Test Research on Two Motors Driven Double Crank Ring-Plate-Type Pin-Cycloid-Gear Planetary Drive
reducer also has some shortcomings, such as the small contact ratio, the large pressure angle, the usage of ‘soft’ gear tooth of the internal involute gear, and the difficulty to achieve dynamic balance. The double crank ring-plate-type pin-cycloid-gear planetary drive (Chinese patent ZL02231994.8) we developed can creatively overcome the shortcomings of the two kinds of reducers previously mentioned. Its loadcarrying capacity is greatly increased. Especially, the drive can achieve dynamic balance with four ring plates so that the operation of the reducer is extremely smooth. The appearance of the new development would surely provide the reducer industry a brand new cycloid planetary drive which has small volume, light weight, wide range of transmission ratio, high transmission efficiency, simple construction, high rigidity of the output shaft, much higher load-carrying capacity [1],[2],[3] and high valuation in practice. During the optimization design of the new drive, with the given parameter and overall size, the load-carrying capacity of the whole drive can be greatly increased by the tooth profile optimization [4] and the parameter optimization [5]. Meanwhile, under the condition of the strength, the shape of the ring plate is optimally designed to reduce its weight and its vibration during operating. In order to validate the theory of the optimization design [6], three prototypes with different structural designs have been developed and manufactured and the load-carry capacity, transmission efficiency, vibration and noise intensity of the prototypes has been tested. The results show that the design theory is right. II. Kinematics principle and structural characteristics A. Kinematics principle The kinematics diagram of the double crank ring-platetype cycloid drive is shown in figure 1. The pin gear is mounted on the coupler (ring-plate) BC of a parallel linkage ABCD . The center OP of the pin gear is at the middle point of the coupler. The center OC of the cycloid gear 5, which meshes with the pin gear 2, is at the middle point of the fixed link AD . The length l of the crank is equal to the eccentricity OP OC between the pin gear and cycloid gear.

The Dangers of Smoking。

Smoking is a dangerous habit. It causes many different diseases, such as lung cancer and heart disease. Many people die from smoking-related illnesses every year. In addition, smoking can harm other people who are nearby. This is called passive smoking. The smoke from a cigarette not only affects the person who is smoking, but also the people around them. This is why many countries have banned smoking in public places.Part II Global Reading。

附件2:外文原文(复印件)Performance of RC frames with hybrid reinforcement under reversed cyclic loadingM. Nehdi and A. SaidDept, of Civil & Env. Eng., The University of Western Ontario, London, Ontario, Canada, N6A 5B9Received." 5 May 2004; accepted." 13 October 2004ABSTRACTThe use of FRP as reinforcement in concrete structures has been growing rapidly.A potential application of FRP reinforcement is in reinforced concrete (RC) frames. However, due to FRP's predominantly elastic behaviour, FRP-RC members exhibit low ductility and energy dissipation. Hybrid steel-FRP reinforcement can be a viable solution to the lack of ductility of FRP-RC members. Using two layers of reinforcement in a section, FRP rebars can be placed in the outer layer and steel rebars in the inner layer away from the effects of carbonation and chloride intrusion. Combined with the use of FRP stirrups, this approach can enhance the corrosion resistance of RC members.However, current design standards and detailing criteria for FRP-RC structures do not provide detailed seismic provisions. In particular, the design and detailing of beam-column joints is a key issue in seismic design. During recent earthquakes, many structural collapses were initiated or caused by beam-column joint failures. Thus, research is needed to gain a better understanding of the behaviour of FRP and hybrid FRP-steel-RC under seismic loading. In this study, three full-scale beam-column joint specimens reinforced with steel, GFRP and a hybrid GFRP-steel configuration, respectively were tested in order to investigate their performance in the event of an earthquake.1.INTRODUCTIONCorrosion of reinforcing steel has been the primary cause of deterioration of reinforced (RC) structures, requiring substantial annual repair costs around the world. Furthermore, modem equipments that employ magnetic interferometers, such as in hospitals, require a nonmagnetic environment with no metallic reinforcement. This has led to an increasing interest in fibrereinforced polymers (FRP) reinforcement, which is inherently nonmagnetic and resistant to corrosion [1].Measurement devices for structural health monitoring purposes. However, FRP materials often exhibit weaker bond to concrete and lower ductility compared to that of conventional steel reinforcement. The bond of FRP to concrete can be improved by means of mechanical anchorages such as surface deformations and sand coating, but its lower ductility remains a major concern, especially in structures subjected to seismic and/or impact loading.Brown and Bartholomew [2] observed that FRP-RC beams behaved in a similar manner to that of steel-RC beams.However, in the design process, two criteria that are not usually problematic in thecase of steel reinforcement can govern the design in the case of FRP reinforcement: deflection and ductility. Most FRP materials usually have a significantly lower modulus of elasticity compared to that of steel (except for some new CFRP products) and thus, often generate higher deflections, Furthermore, the predominantly elastic behaviour of FRP results in little warning before a usually sudden and brittle failure. Satisfying deflection and ductility requirements is a challenge in designing FRP-RC structures. Thus, it is recommended that flexural design of FRP-reinforced slabs and beams should aim at over-reinforced sections in order to achieve a concrete compression failure, which usually allows FRP-RC flexural members to exhibit some plastic behaviour before failure [3, 4].In recent years, there has been a growing interest to investigate the performance of mixed steel-FRP as well as steel-free FRP-RC structures. However, research in this area has been generally limited to some beam and column testing.Most of the newly adopted specifications for the design of FRP-reinforced concrete [4-8] are not comprehensive, often do not include detailed seismic provisions, and do not cover hybrid FRP-steel RC systems. Therefore, research is needed to investigate the performance of FlIP and hybrid FRP-steelreinforced concrete frames under reversed cyclic loading in order to form the basis for future design code provisions for FRP-reinforced concrete in seismic zones. In this study, fullscale steel-reinforced, steel-free GFRP-reinforced, and hybrid GFRP-steel-reinforced beam-column joints were tested under reversed cyclic loading; Their behaviour including load-storey drift envelope relationship and energy dissipation were compared and discussed.2. SCOPE OF PREVIOUS WORKThe use of FRP as reinforcement in RC beams was investigated by various researchers. Different permutations of FlIP and steel as longitudinal and transverse reinforcement,respectively were studied [9-11]. Although transverse reinforcement is usually closer to the concrete surface and is therefore more vulnerable to corrosion, limited investigations have been performed on the use of FRP stirrups. The use of FlIP stirrups has been hindered by their limited availability and the fact that a 60% strength reduction factor at bends for various types of FRP is recommended [6]. Also, bending FRP bars to make stirrups typically needs to be performed in production plants with special care and equipment. The use of FRP NEFMAC (New Fiber Composite Material for Reinforcing Concrete) grids can provide a solution to such a problem; a four-ceU unit taken from a NEFMAC grid provides a three-branched stirrup as shown in Fig.Grira and Saatcioglu [12] investigated the use of both steel grids and CFRP grids as stirrups for confinement of concrete columns having longitudinal steel reinforcement. Several grid configurations were used and column specimens were tested under cyclic loading. They concluded that the performance of columns reinforced with CFRP stirrups was comparable to that of columns reinforced with steel stirrups. They also argued that the use of grids whether made of steel or CFRP provides ease of construction and a near-uniform distribution of the confinement pressure along the column, without congesting the reinforcement cage. They reported that the NEFMAC gridbased stirrups failed at their nodes, which is usually thecommon weakness of FRP stirrups. Fukuyama et al. [13] tested a half-scale three-storey AFRP-reinforced concrete frame under quasi-static loading. RA11S aramid-bars were used for the longitudinal reinforcement of columns, RA7S bars were used as flexural reinforcement for beams and slabs, while RA5 bars were used as shear reinforcement. RA11S, RA7S and RA5 are braided bars with cross-sectional areas of 90, 45 and 23 mm 2, respectively. It was argued that frame deformations governed the design. The frame remained elastic up to a drift angle of 1/50 rad, and no substantial decrease in strength took place after rupture of some main beam rebars owing to the high degree of structural indeterminacy of the frame. It was also noted that the rehabilitation of such a frame was easier than that of conventional RC flames since residual deformations were smaller. However, the flame was not tested to collapse and its behaviour under excessive deformations was not reported. Limited research has been performed on hybrid FRP-steel reinforced concrete. Aiello and Ombres [14] tested 6 beams with different configurations of longitudinal reinforcement including steel only, AFRP only, and hybrid AFRP-steel beams, all with steel stirrups. For some of the hybrid specimens, steel was placed with a larger concrete cover to provide extra protection against corrosion. Experimental results showed that such a hybrid system can have lower service deflection and higher ductility at failure than that of the AFRP steel-flee system. Leung and Balendran [15] tested seven RC beams under four point bending. Concrete strength and reinforcement ratios for both steel and GFRP were varied to produce under-reinforced and over-reinforced sections. Steel rebars were placed at 30 mm higher concrete cover compared to that for GFRP rebars. The study showed that for hybrid beams, steel contributed more effectively to the overall behaviour up to yield. Afterwards, the stiffness of yielded steel dropped drastically and the GFRP rebars started to contribute more efficiently to the section resistance. For high strength concrete beams, the increased flexural capacity resulted in shifting the flexural failure into a shear failure.Some research focused on providing ductility to FRP rebars that are manufactured by filament winding or pultrusion. For instance, Tamuzs and Tepfers [16] investigated the properties of a hybrid FRP rod. They used multiple fibre types along with braiding fibre strands around a soft porous core to achieve a more ductile behaviour. The hybrid rods they produced could provide a ductile behaviour, but the difference between the moduli of different fibre strands seemed to cause uneven load transfer, while the compression of the core material caused a reduction of cross-section. A similar study was performed by Bakis et al. [17] who developed pseudo- ductile FRP rods using different types of fibres. The rods behaved in a pseudo-ductile manner when tested under tension, but premature failure took place due to local stress concentrations. Another study performed by Harris et al. [18] developed a ductile hybrid FRP rebar through braiding of various fibres followed by a pultrusion process. Belarbi et al. [19] were also successful in developing composite reinforcing rebars with a relatively more stable stress-strain behaviour in tension and better load-deflection behaviour under four-point bending. However, such rebars are still in early experimental stages and there is not enough data on their field performance, especially under seismic loading.3. EXPERIMENTAL PROGRAMBeam-column joints can be isolated from plane frames at the points of contraflexure. The beam of the current test unit is taken to the mid-span of the bay, while the column is taken from the mid-height of one storey to the mid-height of the next storey.3.1 Steel-reinforced specimen (J1)3.2 GFRP-reinforced specimen (J4)3.3 Hybrid-reinforced specimen (J5)3.4 Test setup and procedure5. DISCUSSIONThe use of FRP as reinforcement in concrete structures has been increasing in popularity, yet various design guidelines and provisions still need to be developed for its safe implementation in large-scale field applications. For instance, the ACI 440.1R-01 identified a wide variety of research issues pertaining to FRP that need to be addressed, some of which are as simple as establishing the statistical variation of the tensile capacity of FRP rebars. Moreover, the contribution of FRP transverse reinforcement to the shear capacity of RC elements needs to be properly evaluated. The lower bond strength of FRP to concrete compared to that of steel imposes difficulties in design, for instance in satisfying rebar development length such as in the case of beam reinforcement anchorage in exterior joints, for which using FRP would require additional embedded length compared to when steel rebars are used. Also the difficulty of manufacturing bends in FRP makes it difficult to adopt this material in reinforcing structurally complicated configurations and needs to be addressed.A major drawback of steel-free FRP-RC systems is their low energy dissipation under earthquake loading, as demonstrated by the performance of the tested FRP-reinforced joint specimen (J4). The energy input from ground motion is equal to the sum of potential, kinematic, damping and hysteretic energy components [22]. The potential and kinematic energy components vanish after the static equilibrium of the structure is reached, while the damping and hysteretic energy components are responsible for energy dissipation. The hysteretic component becomes the major contributor to energy dissipation when significant inelastic deformations take place. Hence, an FRP-reinforced frame may have to be designed with a high damping component so that when added to its relatively limited hysteretic Component, it can dissipate the energy input during an earthquake. Design guidelines for framed RC buildings by the Architecture Institute of Japan, as outlined by Kobayashi et al. [23], entail ensuring seismic performance by overcoming the ductility deficiency of FRP-RC frames. The study recommended the use of the capacity spectrum method. Performance demand and capacity spectra were evaluated and a performance point, where the demand and capacity spectra meet and members are still below their flexural capacity, was defined as the safety limit. This performance-based design approach was successfully applied to the analysis of a 9-floor FRP-RC frame. The study also pointed out the cruciality of damping in FRP-RC structures and recommended the use of vibration control devices.The use of hybrid steel-FRP RC systems could address many of the drawbacks ofsteel-free RC systems. Steel reinforcement can be used in lateral load resisting structural members, which are not usually exposed to aggressive media, while FRP reinforcement can be used in the envelope of the structure to enhance durability. Alternatively, a hybrid reinforcement configuration can make use of the corrodible steel at a thick concrete cover, while the more durable FRP stays at a minimum cover. Thus, the structure can benefit from using such a hybrid reinforcement system to provide both durability (using FRP) and post-peak reserve strength (using steel).The present study focussed only on comparing the behaviour of FRP, hybrid steel-FRP, and steel-reinforced beam-column joints. Full-scale tests on entire FRP and hybrid-reinforced frames need to be performed to assess the progress of failure globally. The results can be used to calibrate numerical models that can be used to simulate the behaviour of multi-storey FRP and hybrid-reinforced frames with high degrees of redundancy, and accordingly predict the progress of failure. Moreover, passive energy dissipation devices can provide a source of energy dissipation for FRP-reinforced frames, which needs further focussed research. Overall, research efforts are still needed to address many questions and uncertainties, and to develop adequate design provisions dedicated to steel-free and hybrid RC systems, before their widespread use in demanding large-scale structural applications becomes feasible and safe in seismic areas.6. CONCLUSIONSAn effort was made to investigate the performance of GFRP and hybrid steel-GFRP-reinforced beam-column joints and to compare their behaviour to that of standard steel-reinforced beam-column joints under reversed quasi- static (cyclic) loading.,the following conclusions can be drawn:The GFRP-reinforced beam-column joint showed very low plasticity features when tested under reversed cyclic loading. This resulted in lower energy dissipation compared to that of the steel and hybrid reinforced specimens.The hybrid GFRP-steel-reinforced beam-colunm joint showed lower stiffness than that of the conventional steel- reinforced beam-column joint, but exhibited higher stiffness than that of the GFRP-reinforced specimen.The GFRP and hybrid-reinforced specimens showed satisfactory drift capacity, assuming a minimum drift requirement of 3% (0.03 rad) as recommended in the literature for ductile RC flame buildings [24].A hybrid RC system could be tailored to provide a range of performance requirements such as durability, stiffness, strength, ductility, etc. A designer may adapt the reinforcement configuration of the hybrid system to accommodate a balance between such design criteria.This study was only focussed on the level of the subassemblage. A more global concept should be adopted in the design of moment-resisting frames. Thorough dynamic analysis of GFRP and hybrid-RC structures should be performed to better assess their capacity in meeting seismic resistance requirements.Design code provisions for the seismic design of RC structures, which have been developed for ductile steel reinforcement, need to be re-evaluated for FRP-RC structures.。

这篇演说震惊了西方整个学术界,这不仅因为舒尔茨一向给人的印象是一位农业经济学家,而且还因为一般人总以为资本是有形的、物质的,至于教育、在职训练、保健、人口流动等方面的投资也可以增加一国资本存量和加速经济发展的观念对于当时的经济学界来说的确是很新鲜的。

这次会议之后,人力资本成为经济学中一个非常热门的新兴领域,“人力资本”也成了西方教育经济学的基本概念,人力资本理论成为现代西方资产阶级发展经济学的一个主要学派。

《人力资本投资》---- 内容提要舒尔茨这篇《人力资本投资》被人称之为:人力资本研究新领域的“独立宣言”,其在文中提出了九项主张:“在税收政策上应该给人力资本给予优惠;防止人人力资本的闲置和老化;避免对人力资本投资进行人为的干扰;完善人力资本市场,银行应积极主动地提供人力资本所需的费用,鼓励私人和公共投资;政府应承担人力资本投资的大部分费用,特别是资助劳动力向城市转移;重视低收入者的人力资本投资;明确教育和保健同样具有经济意义,它们是一项投资,要扭转投资在这方面的不平衡;增加政府投入、扩大人力资本投资,以减少收入的不平等;舒尔茨所提出的人力资本理论的基本内涵是:把资本分为物质资本和人力资本两种形式。

The Chrysanthemumsby John SteinbeckElisa is a young married lady working on an isolated farm and proud of her skills in growing flowers. One day, she suddenly feels a desire to communicate with the outside world. What happens to her? Please read the following story.The high grey-flannel fog of winter closed off the Salinas Valley from the sky and from all the rest of the world. On every side it sat like a lid on the mountains and made of the great valley a closed 10pot. On the broad, level land floor the gang plows bit deep and left the black earth shining like metal where the shares had cut. On the foothill ranches across the Salinas River, the yellow stubble fields seemed to be bathed in pale cold sunshine, but there was no sunshine in the valley now in December. The thick willow scrub along the river flamed with sharp and positive yellow leaves.It was a time of quiet and of waiting. The air was cold and tender. A light wind blew up from the southwest so that the farmers were mildly hopeful of a good rain before long; but fog and rain do not go together.20Across the river, on Henry Allen's foothill ranch there was little work to be done, for the hay was cut and stored and the orchards were plowed up to receive the rain deeply when it should come.The cattle on the higher slopes were becoming shaggy and rough-coated.Elisa Allen, working in her flower garden, looked down across the yard and saw Henry, her husband, talking to two men in business suits. The three of them stood by the tractor shed, each man with one foot on the side of the little Fordson. They smoked cigarettes and studied the machine as they talked.Elisa watched them for a moment and then went back to her work. She was thirty-five. Her face was lean and strong and her eyes were as clear as water. Her figure looked blocked and heavy in 30her gardening costume, a man's black hat pulled low down over her eyes, clod-hopper shoes, a figured print dress almost completely covered by a big corduroy apron with four big pockets to hold the snips, the trowel and scratcher, the seeds and the knife she worked with. She wore heavy leather gloves to protect her hands while she worked.She was cutting down the old year's chrysanthemum stalks with a pair of short and powerful scissors. She looked down toward the men by the tractor shed now and then. Her face was eager and mature and handsome; even her work with the scissors was over-eager, over-powerful. The chrysanthemum stems seemed too small and easy for her energy.40She brushed a cloud of hair out of her eyes with the back of her glove, and left a smudge of earth on her cheek in doing it. Behind her stood the neat white farm house with red geraniums close-banked around it as high as the windows. It was a hard-swept looking little house with hard-polished windows, and a clean mud-mat on the front steps.Elisa cast another glance toward the tractor shed. The strangers were getting into their Ford coupe.She took off a glove and put her strong fingers down into the forest of new green chrysanthemum sprouts that were growing around the old roots. She spread the leaves and looked down among the close-growing stems. No aphids were there, no sowbugs or snails or cutworms. Her terrier fingers 50destroyed such pests before they could get started.Elisa started at the sound of her husband's voice. He had come near quietly, and he leaned over the wire fence that protected her flower garden from cattle and dogs and chickens."At it again," he said. "You've got a strong new crop coming." Elisa straightened her back and pulled on the gardening glove again: "Yes. They'll be strong this coming year." In her tone and on her face there was a little smugness. "You've got a gift with things," Henry observed. "Some of those yellow chrysanthemums you had this year were ten inches across. I wish you'd work out in the orchard and raise some apples that big." Her eyes sharpened. "Maybe I could do it, too. I've a 60gift with things, all right. My mother had it. She could stick anything in the ground and make it grow. She said it was having planters' hands that knew how to do it." "Well, it sure works with flowers," he said. "Henry, who were those men you were talking to?" "Why, sure, that's what I came to tell you. They were from the Western Meat Company. I sold those thirty head of three-year-old steers. Got nearly my own price, too.""Good," she said. "Good for you." "And I thought," he continued, "I thought how it's Saturday afternoon, and we might go into Salinas for dinner at a restaurant, and then to a picture show -to celebrate, you see." "Good," she repeated. "Oh, yes. That will be good." Henry put on his joking tone. "There's fights tonight. How'd you like to go to the fights?" "Oh, no," she said breathlessly.70"No, I wouldn't like fights." "Just fooling, Elisa. We'll go to a movie. Let's see. It's two now. I'm going to take Scotty and bring down those steers from the hill. It'll take us maybe two hours. We'll go in town about five and have dinner at the Cominos Hotel. Like that?" "Of course I'll like it. It's good to eat away from home." "All right, then. I'll go get up a couple of horses." She said, "I'll have plenty of time to transplant some of these sets, I guess."She heard her husband calling Scotty down by the barn. And a little later she saw the two men ride up the pale yellow hillside in search of the steers. There was a little square sandy bed kept for rooting the chrysanthemums. With her trowel she turned the soil over and over, and smoothed it and patted it firm. Then she dug ten parallel trenches to receive the sets. Back at the 80chrysanthemum bed she pulled out the little crisp shoots, trimmed off the leaves of each one with her scissors and laid it on a small orderly pile.A squeak of wheels and plod of hoofs came from the road. Elisa looked up. The country road ranalong the dense bank of willows and cottonwoods that bordered the river, and up this road came a curious vehicle, curiously drawn. It was an old spring-wagon, with a round canvas top on it like the cover of a prairie schooner. It was drawn by an old bay horse and a little grey-and-white burro.A big stubble-bearded man sat between the cover flaps and drove the crawling team. Underneaththe wagon, between the hind wheels, a lean and rangy mongrel dog walked sedately. Words werepainted on the canvas, in clumsy, crooked letters. "Pots, pans, knives, scissors, lawn mowers.90Fixed." Two rows of articles, and the triumphantly definitive "Fixed" below. The black paint had run down in little sharp points beneath each letter.Elisa, squatting on the ground, watched to see the crazy, loose-jointed wagon pass by. But it didn't pass. It turned into the farm road in front of her house, crooked old wheels skirling and squeaking.The rangy dog darted from between the wheels and ran ahead. Instantly the two ranch shepherds flew out at him. Then all three stopped, and with stiff and quivering tails, with taut straight legs, with ambassadorial dignity, they slowly circled, sniffing daintily. The caravan pulled up to Elisa's wire fence and stopped. Now the newcomer dog, feeling out-numbered, lowered his tail and retired under the wagon with raised hackles and bared teeth.100The man on the wagon seat called out, "That's a bad dog in a fight when he gets started." Elisa laughed. "I see he is. How soon does he generally get started?" The man caught up her laughter and echoed it heartily. "Sometimes not for weeks and weeks,” he said. He climbed stiffly down, over the wheel. The horse and the donkey drooped like unwatered flowers. Elisa saw that he was a very big man. Although his hair and beard were greying, he did not look old. His worn black suit was wrinkled and spotted with grease. The laughter had disappeared from his face and eyes the moment his laughing voice ceased. His eyes were dark, and they were full of the brooding that gets in the eyes of teamsters and of sailors. The calloused hands he rested on the wire fence were cracked, and every crack was a black line. He took off his battered hat.110"I'm off my general road, ma'am," he said. "Does this dirt road cut over across the river to the Los Angeles highway?" Elisa stood up and shoved the thick scissors in her apron pocket. "Well, yes, it does, but it winds around and then fords the river. I don't think your team could pull through the sand." He replied with some asperity, "It might surprise you what them beasts can pull through.""When they get started?" she asked. He smiled for a second. "Yes. When they get started." "Well,"said Elisa, "I think you'll save time if you go back to the Salinas road and pick up the highway there." He drew a big finger down the chicken wire and made it sing. "I ain't in any hurry, ma'am. I go from Seattle to San Diego and back every year. Takes all my time. About six months each way.I aim to follow nice weather."120Elisa took off her gloves and stuffed them in the apron pocket with the scissors. She touched the under edge of her man's hat, searching for fugitive hairs. "That sounds like a nice kind of a way to live," she said. He leaned confidentially over the fence. "Maybe you noticed the writing on my wagon. I mend pots and sharpen knives and scissors. You got any of them things to do?" "Oh, no,"she said quickly. "Nothing like that." Her eyes hardened with resistance. "Scissors is the worst thing," he explained. "Most people j ust ruin scissors trying to sharpen ‘em, but I know how. I got a special tool. It's a little bobbit kind of thing, and patented. But it sure does the trick." "No. My scissors are all sharp." "All right, then. Take a pot," he continued earnestly, "a bent pot, or a pot with a hole. I can make it like new so you don't have to buy no new ones. That's a saving for you." 130"No," she said shortly. "I tell you I have nothing like that for you to do."His face fell to an exaggerated sadness. His voice took on a whining undertone. "I ain't had a thingto do today. Maybe I won't have no supper tonight. You see I'm off my regular road. I know folks on the highway clear from Seattle to San Diego. They save their things for me to sharpen up because they know I do it so good and save them money." "I'm sorry," Elisa said irritably. "I haven't anything for you to do." His eyes left her face and fell to searching the ground. They roamed about until they came to the chrysanthemum bed where she had been working. "What's them plants, ma'am?" The irritation and resistance melted from Elisa's face. "Oh, those are chrysanthemums, giant whites and yellows. I raise them every year, bigger than anybody around 140here." "Kind of a long-stemmed flower? Looks like a quick puff of colored smoke?" he asked."That's it. What a nice way to describe them." "They smell kind of nasty till you get used to them,"he said. "It's a good bitter smell," she retorted, "not nasty at all." He changed his tone quickly. "I like the smell myself." "I had ten-inch blooms this year," she said.The man leaned farther over the fence. "Look. I know a lady down the road a piece, has got the nicest garden you ever seen. Got nearly every kind of flower but no chrysanthemums. Last time I was mending a copper-bottom washtub for her (that's a hard job but I do it good), she said to me, 'If you ever run across some nice chrysanthemums I wish you'd try to get me a few seeds.' That's what she told me.”Elisa's eyes grew alert and eager. "She couldn't have known much about 150chrysanthemums. You can raise them from seed, but it's much easier to root the little sprouts you see there." "Oh," he said. "I s'pose I can't take none to her, then." "Why yes you can," Elisa cried."I can put some in damp sand, and you can carry them right along with you. They'll take root in the pot if you keep them damp. And then she can transplant them." "She'd sure like to have some, ma'am. You say they're nice ones?" "Beautiful," she said. "Oh, beautiful." Her eyes shone. She tore off the battered hat and shook out her dark pretty hair. "I'll put them in a flower pot, and you can take them right with you. Come into the yard."While the man came through the picket gate Elisa ran excitedly along the geranium-bordered path to the back of the house. And she returned carrying a big red flower pot. The gloves were forgotten 160now. she kneeled on the ground by the starting bed and dug up the sandy soil with her fingers and scooped it into the bright new flower pot. Then she picked up the little pile of shoots she had prepared. With her strong fingers she pressed them into the sand and tamped around them with her knuckles. The man stood over her. "I'll tell you what to do," she said. "You remember so you can tell the lady." "Yes, I'll try to remember." "Well, look. These will take root in about a month. Then she must set them out, about a foot apart in good rich earth like this, see?" She lifted a handful of dark soil for him to look at. "They'll grow fast and tall. Now remember this: In July tell her to cut them down, about eight inches from the ground." "Before they bloom?" he asked. "Yes, before they bloom." Her face was tight with eagerness. "They'll grow right up again. About the last of September the buds will start."170She stopped and seemed perplexed. "It's the budding that takes the most care," she said hesitantly."I don't know how to tell you." She looked deep into his eyes, searchingly. Her mouth opened a little, and she seemed to be listening. "I'll try to tell you,” she said. “Did you ever hear of planting hands?" "Can't say I have, ma'am." "Well, I can only tell you what it feels like. It's when you're picking off the buds you don't want. Everything goes right down into your fingertips. You watch your fingers work. They do it themselves. You can feel how it is. They pick and pick the buds.They never make a mistake. They're with the plant. Do you see? Your fingers and the plant. You can feel that, right up your arm. They know. They never make a mistake. You can feel it. When you're like that you can't do anything wrong. Do you see that? Can you understand that?" She was 180kneeling on the ground looking up at him. Her breast swelled passionately. The man's eyes narrowed. He looked away self-consciously. "Maybe I know," he said. "Sometimes in the night in the wagon there -"Elisa's voice grew husky. She broke in on him, "I've never lived as you do, but I know what you mean. When the night is dark -why, the stars are sharp-pointed, and there's quiet. Why, you rise up and up! Every pointed star gets driven into your body. It's like that. Hot and sharp and -lovely." Kneeling there, her hand went out toward his legs in the greasy black trousers. Her hesitant fingers almost touched the cloth. Then her hand dropped to the ground. She crouched low like a fawning dog. He said, "it's nice, just like you say. Only when you don't have no dinner, it 190ain't." She stood up then, very straight, and her face was ashamed. She held the flower pot out to him and placed it gently in his arms. "Here. Put it in your wagon, on the seat, where you can watch it. Maybe I can find something for you to do." At the back of the house she dug in the can pile and found two old and battered aluminum saucepans. She carried them back and gave them to him."Here, maybe you can fix these."His manner changed. He became professional. "Good as new I can fix them." At the back of his wagon he set a little anvil, and out of an oily tool box dug a small machine hammer. Elisa came through the gate to watch him while he pounded out the dents in the kettles. His mouth grew sure and knowing. At a difficult part of the work he sucked his under-lip. "You sleep right in the 200wagon?" Elisa asked. "Right in the wagon, ma'am. Rain or shine I'm dry as a cow in there." "It must be nice," she said. "It must be very nice. I wish women could do such things." "It ain't the right kind of a life for a woman." Her upper lip raised a little, showing her teeth. "How do you know? How can you tell?" she said. "I don't know, ma'am," he protested. "Of course I don't know.Now here's your kettles, done. You don't have to buy no new ones." "How much?" "Oh, fifty cents'll do. I keep my prices down and my work good. That's why I have all them satisfied customers up and down the highway."Elisa brought him a fifty-cent piece from the house and dropped it in his hand. "You might be surprised to have a rival some time. I can sharpen scissors, too. And I can beat the dents out of 210little pots. I could show you what a woman might do." He put his hammer back in the oily box and shoved the little anvil out of sight. "It would be a lonely life for a woman, ma'am, and a scarey life, too, with animals creeping under the wagon all night." He climbed over the singletree, steadying himself with a hand on the burro's white rump. He settled himself in the seat, picked up the lines."Thank you kindly, ma'am," he said. "I'll do like you told me; I'll go back and catch the Salinas road." "Mind," she called, "if you're long in getting there, keep the sand damp." "Sand, ma'am?...sand? Oh, sure. You mean around the chrysanthemums. Sure I will." He clucked his tongue. The beasts leaned luxuriously into their collars. The mongrel dog took his place between the back wheels. The wagon turned and crawled out the entrance road and back the way it had come, along the river.220Elisa stood in front of her wire fence watching the slow progress of the caravan. Her shoulders were straight, her head thrown back, her eyes half-closed, so that the scene came vaguely into them. Her lips moved silently, forming the words "Good-bye -good-bye." Then she whispered, "That's a bright direction. There's a glowing there." The sound of her whisper startled her. She shook herself free and looked about to see whether anyone had been listening. Only the dogs had heard. They lifted their heads toward her from their sleeping in the dust, and then stretched out their chins and settled asleep again. Elisa turned and ran hurriedly into the house.In the kitchen she reached behind the stove and felt the water tank. It was full of hot water from 230the noonday cooking. In the bathroom she tore off her soiled clothes and flung them into the corner. And then she scrubbed herself with a little block of pumice, legs and thighs, loins and chest and arms, until her skin was scratched and red. When she had dried herself she stood in front of a mirror in her bedroom and looked at her body. She tightened her stomach and threw out her chest.She turned and looked over her shoulder at her back.After a while she began to dress, slowly. She put on her newest underclothing and her nicest stockings and the dress which was the symbol of her prettiness. She worked carefully on her hair, penciled her eyebrows and rouged her lips. Before she was finished she heard the little thunder of hoofs and the shouts of Henry and his helper as they drove the red steers into the corral. She heard 240the gate bang shut and set herself for Henry's arrival. His step sounded on the porch. He entered the house calling, "Elisa, where are you?" "In my room, dressing. I'm not ready. There's hot water for your bath. Hurry up. It's getting late."When she heard him splashing in the tub, Elisa laid his dark suit on the bed, and shirt and socks and tie beside it. She stood his polished shoes on the floor beside the bed. Then she went to the porch and sat primly and stiffly down. She looked toward the river road where the willow-line was still yellow with frosted leaves so that under the high grey fog they seemed a thin band of sunshine.This was the only color in the grey afternoon. She sat unmoving for a long time. Her eyes blinked rarely. Henry came banging out of the door, shoving his tie inside his vest as he came. Elisa 250stiffened and her face grew tight. Henry stopped short and looked at her. "Why -why, Elisa.You look so nice!" "Nice? You think I look nice? What do you mean by 'nice'?"Henry blundered on. "I don't know. I mean you look different, strong and happy.""I am strong? Yes, strong. What do you mean 'strong'?" He looked bewildered. "You're playing some kind of a game," he said helplessly."It's a kind of a play. You look strong enough to break a calf over your knee, happy enough to eat it like a watermelon." For a second she lost her rigidity."Henry! Don't talk like that. You didn't know what you said." She grew complete again. "I'm strong," she boasted. "I never knew before how strong." Henry looked down toward the tractor shed, and when he brought his eyes back to her, they were his own again. "I'll get out the car. You 260can put on your coat while I'm starting." Elisa went into the house. She heard him drive to the gate and idle down his motor, and then she took a long time to put on her hat. She pulled it here and pressed it there. When Henry turned the motor off she slipped into her coat and went out.The little roadster bounced along on the dirt road by the river, raising the birds and driving therabbits into the brush. Two cranes flapped heavily over the willow-line and dropped into the river-bed. Far ahead on the road Elisa saw a dark speck. She knew. She tried not to look as they passed it, but her eyes would not obey. She whispered to herself sadly, "He might have thrown them off the road. That wouldn't have been much trouble, not very much. But he kept the pot," she explained. "He had to keep the pot. That's why he couldn't get them off the road." The roadster 270turned a bend and she saw the caravan ahead. She swung full around toward her husband so she could not see the little covered wagon and the mismatched team as the car passed them. In a moment it was over. The thing was done. She did not look back. She said loudly, to be heard above the motor, "It will be good, tonight, a good dinner.""Now you're changed again," Henry complained. He took one hand from the wheel and patted her knee. "I ought to take you in to dinner oftener. It would be good for both of us. We get so heavy out on the ranch." "Henry," she asked, "could we have wine at dinner?" "Sure we could. Say! That will be fine." She was silent for a while; then she said, "Henry, at those prize fights, do the men hurt each other very much?" "Sometimes a little, not often. Why?" "Well, I've read how they break 280noses, and blood runs down their chests. I've read how the fighting gloves get heavy and soggy with blood." He looked around at her. "What's the matter, Elisa? I didn't know you read things like that." He brought the car to a stop, then turned to the right over the Salinas River bridge. "Do any women ever go to the fights?" she asked. "Oh, sure, some. What's the matter, Elisa? Do you want to go? I don't think you'd like it, but I'll take you if you really want to go." She relaxed limply in the seat. "Oh, no. No. I don't want to go. I'm sure I don't." Her face was turned away from him. "It will be enough if we can have wine. It will be plenty." She turned up her coat collar so he could not see that she was crying weakly -like an old woman.。

英语美文原文及其译文篇1Storms Always Give Way to the Sun阳光总在风雨后What is the secret ingredient of tough people that enanble them to succeed? Why do they survive the tough times when others are overcome by them? why do they win when others lose, why do they soar when others sink?The answer is very simple. It is all in how they perceive their problems. Yes,every living person has problems. A problem-free life is an illsion - a mirage in the desert. Accept that fact.Every mountain has a peak. Every valley has its low point. Life has its ups and downs, its peaks and its valleys. No one is up all the time, nor are they down all the time. Problems do end, they are all resolved in time.You may not be able to control the times, but you can compose your response. You can turn your pain into provanity or into poetry. The choice is up to you. You may not have chosen your tough time, but you can choose how you will react to it. For instance, what is the positive reaction to a terrible financial setback? Would it be a positive reaction to cop out or run away? Escape through alcohol? No! Such negative reactions only produce greater problems by promising a temporary "solution" to the pressing problem. The positve solution to a problem may require courage to initiate it. When you control your reaction tothe seemingly uncontrolable problem of life, then in fact you do control the problem's effect on you. Your reaction to the problem is the last word! That is bottom line. What will you let this problem do to you? It can make you tender or tough. It can make you better or bitter. It all depends on you.In the final analysis, tough people who survive the tough times do so because they have chosen to react positvely to their predicament. Tough times never last, but tough people do. Tough people stick it out. History teach us that each problem has a lifespan .No problem is permanent.Storms always give way to the sun. Winters always thaws into springtime. Your storm will pass. Your winter will thaw. Your problem would be solved.译文:坚韧不拔的人成功的秘诀是什么?他们为什么能挺过艰难的时刻,而其他人却被困难所压倒?为什么成功的是他们而失败的人是其他人?为什么他们一飞冲天,而其他人却深陷泥沼?答案很简单,全看他们是如何看待自己面临的难题的。

外文文献翻译原文Analysis of Con tin uous Prestressed Concrete BeamsChris BurgoyneMarch 26, 20051、IntroductionThis conference is devoted to the development of structural analysis rather than the strength of materials, but the effective use of prestressed concrete relies on an appropriate combination of structural analysis techniques with knowledge of the material behaviour. Design of prestressed concrete structures is usually left to specialists; the unwary will either make mistakes or spend inordinate time trying to extract a solution from the various equations.There are a number of fundamental differences between the behaviour of prestressed concrete and that of other materials. Structures are not unstressed when unloaded; the design space of feasible solutions is totally bounded;in hyperstatic structures, various states of self-stress can be induced by altering the cable profile, and all of these factors get influenced by creep and thermal effects. How were these problems recognised and how have they been tackled?Ever since the development of reinforced concrete by Hennebique at the end of the 19th century (Cusack 1984), it was recognised that steel and concrete could be more effectively combined if the steel was pretensioned, putting the concrete into compression. Cracking could be reduced, if not prevented altogether, which would increase stiffness and improve durability. Early attempts all failed because the initial prestress soon vanished, leaving the structure to be- have as though it was reinforced; good descriptions of these attempts are given by Leonhardt (1964) and Abeles (1964).It was Freyssineti’s observations of the sagging of the shallow arches on three bridges that he had just completed in 1927 over the River Allier near Vichy which led directly to prestressed concrete (Freyssinet 1956). Only the bridge at Boutiron survived WWII (Fig 1). Hitherto, it had been assumed that concrete had a Young’s modulus which remained fixed, but he recognised that the de- ferred strains due to creep explained why the prestress had been lost in the early trials. Freyssinet (Fig. 2) also correctly reasoned that high tensile steel had to be used, so that some prestress would remain after the creep had occurred, and alsothat high quality concrete should be used, since this minimised the total amount of creep. The history of Freyssineti’s early prestressed concrete work is written elsewhereFigure1:Boutiron Bridge,Vic h yFigure 2: Eugen FreyssinetAt about the same time work was underway on creep at the BRE laboratory in England ((Glanville 1930) and (1933)). It is debatable which man should be given credit for the discovery of creep but Freyssinet clearly gets the credit for successfully using the knowledge to prestress concrete.There are still problems associated with understanding how prestressed concrete works, partly because there is more than one way of thinking about it. These different philosophies are to some extent contradictory, and certainly confusing to the young engineer. It is also reflected, to a certain extent, in the various codes of practice.Permissible stress design philosophy sees prestressed concrete as a way of avoiding cracking by eliminating tensile stresses; the objective is for sufficient compression to remain after creep losses. Untensionedreinforcement, which attracts prestress due to creep, is anathema. This philosophy derives directly from Freyssinet’s logic and is primarily a working stress concept.Ultimate strength philosophy sees prestressing as a way of utilising high tensile steel as reinforcement. High strength steels have high elastic strain capacity, which could not be utilised when used as reinforcement; if the steel is pretensioned, much of that strain capacity is taken out before bonding the steel to the concrete. Structures designed this way are normally designed to be in compression everywhere under permanent loads, but allowed to crack under high live load. The idea derives directly from the work of Dischinger (1936) and his work on the bridge at Aue in 1939 (Schonberg and Fichter 1939), as well as that of Finsterwalder (1939). It is primarily an ultimate load concept. The idea of partial prestressing derives from these ideas.The Load-Balancing philosophy, introduced by T.Y. Lin, uses prestressing to counter the effect of the permanent loads (Lin 1963). The sag of the cables causes an upward force on the beam, which counteracts the load on the beam. Clearly, only one load can be balanced, but if this is taken as the total dead weight, then under that load the beam will perceive only the net axial prestress and will have no tendency to creep up or down.These three philosophies all have their champions, and heated debates take place between them as to which is the most fundamental.2、Section designFrom the outset it was recognised that prestressed concrete has to be checked at both the working load and the ultimate load. For steel structures, and those made from reinforced concrete, there is a fairly direct relationship between the load capacity under an allowable stress design, and that at the ultimate load under an ultimate strength design. Older codes were based on permissible stresses at the working load; new codes use moment capacities at the ultimate load. Different load factors are used in the two codes, but a structure which passes one code is likely to be acceptable under the other.For prestressed concrete, those ideas do not hold, since the structure is highly stressed, even when unloaded. A small increase of load can cause some stress limits to be breached, while a large increase in load might be needed to cross other limits. The designer has considerable freedom to vary both the working load and ultimate load capacities independently; both need to be checked.A designer normally has to check the tensile and compressive stresses, in both the top and bottom fibre of the section, for every load case. The critical sections are normally, but not always, the mid-span and the sections over piers but other sections may become critical ,when the cable profile has to be determined.The stresses at any position are made up of three components, one of which normally has a different sign from the other two; consistency of sign convention is essential.If P is the prestressing force and e its eccentricity, A and Z are the area of the cross-section and its elastic section modulus, while M is the applied moment, then where ft and fc are the permissible stresses in tension and compression.c e t f ZM Z P A P f ≤-+≤Thus, for any combination of P and M , the designer already has four in- equalities to deal with.The prestressing force differs over time, due to creep losses, and a designer isusually faced with at least three combinations of prestressing force and moment;• the applied moment at the time the prestress is first applied, before creep losses occur,• the maximum applied moment after creep losses, and• the minimum applied moment after creep losses.Figure 4: Gustave MagnelOther combinations may be needed in more complex cases. There are at least twelve inequalities that have to be satisfied at any cross-section, but since an I-section can be defined by six variables, and two are needed to define the prestress, the problem is over-specified and it is not immediately obvious which conditions are superfluous. In the hands of inexperienced engineers, the design process can be very long-winded. However, it is possible to separate out the design of the cross-section from the design of the prestress. By considering pairs of stress limits on the same fibre, but for different load cases, the effects of the prestress can be eliminated, leaving expressions of the form:rangestress e Perm issibl Range Mom entZ These inequalities, which can be evaluated exhaustively with little difficulty, allow the minimum size of the cross-section to be determined.Once a suitable cross-section has been found, the prestress can be designed using a construction due to Magnel (Fig.4). The stress limits can all be rearranged into the form:()M fZ PA Z e ++-≤1 By plotting these on a diagram of eccentricity versus the reciprocal of the prestressing force, a series of bound lines will be formed. Provided the inequalities (2) are satisfied, these bound lines will always leave a zone showing all feasible combinations of P and e. The most economical design, using the minimum prestress, usually lies on the right hand side of the diagram, where the design is limited by the permissible tensile stresses.Plotting the eccentricity on the vertical axis allows direct comparison with the crosssection, as shown in Fig. 5. Inequalities (3) make no reference to the physical dimensions of the structure, but these practical cover limits can be shown as wellA good designer knows how changes to the design and the loadings alter the Magnel diagram. Changing both the maximum andminimum bending moments, but keeping the range the same, raises and lowers the feasible region. If the moments become more sagging the feasible region gets lower in the beam.In general, as spans increase, the dead load moments increase in proportion to the live load. A stage will be reached where the economic point (A on Fig.5) moves outside the physical limits of the beam; Guyon (1951a) denoted the limiting condition as the critical span. Shorter spans will be governed by tensile stresses in the two extreme fibres, while longer spans will be governed by the limiting eccentricity and tensile stresses in the bottom fibre. However, it does not take a large increase in moment ,at which point compressive stresses will govern in the bottom fibre under maximum moment.Only when much longer spans are required, and the feasible region moves as far down as possible, does the structure become governed by compressive stresses in both fibres.3、Continuous beamsThe design of statically determinate beams is relatively straightforward; the engineer can work on the basis of the design of individual cross-sections, as outlined above. A number of complications arise when the structure is indeterminate which means that the designer has to consider, not only a critical section,but also the behaviour of the beam as a whole. These are due to the interaction of a number of factors, such as Creep, Temperature effects and Construction Sequence effects. It is the development of these ideas whichforms the core of this paper. The problems of continuity were addressed at a conference in London (Andrew and Witt 1951). The basic principles, and nomenclature, were already in use, but to modern eyes concentration on hand analysis techniques was unusual, and one of the principle concerns seems to have been the difficulty of estimating losses of prestressing force.3.1 Secondary MomentsA prestressing cable in a beam causes the structure to deflect. Unlike the statically determinate beam, where this motion is unrestrained, the movement causes a redistribution of the support reactions which in turn induces additional moments. These are often termed Secondary Moments, but they are not always small, or Parasitic Moments, but they are not always bad.Freyssinet’s bridge across the Marne at Luzancy, started in 1941 but not completed until 1946, is often thought of as a simply supported beam, but it was actually built as a two-hinged arch (Harris 1986), with support reactions adjusted by means of flat jacks and wedges which were later grouted-in (Fig.6). The same principles were applied in the later and larger beams built over the same river.Magnel built the first indeterminate beam bridge at Sclayn, in Belgium (Fig.7) in 1946. The cables are virtually straight, but he adjusted the deck profile so that the cables were close to the soffit near mid-span. Even with straight cables the sagging secondary momentsare large; about 50% of the hogging moment at the central support caused by dead and live load.The secondary moments cannot be found until the profile is known but the cablecannot be designed until the secondary moments are known. Guyon (1951b) introduced the concept of the concordant profile, which is a profile that causes no secondary moments; es and ep thus coincide. Any line of thrust is itself a concordant profile.The designer is then faced with a slightly simpler problem; a cable profile has to be chosen which not only satisfies the eccentricity limits (3) but is also concordant. That in itself is not a trivial operation, but is helped by the fact that the bending moment diagram that results from any load applied to a beam will itself be a concordant profile for a cable of constant force. Such loads are termed notional loads to distinguish them from the real loads on the structure. Superposition can be used to progressively build up a set of notional loads whose bending moment diagram gives the desired concordant profile.3.2 Temperature effectsTemperature variations apply to all structures but the effect on prestressed concrete beams can be more pronounced than in other structures. The temperature profile through the depth of a beam (Emerson 1973) can be split into three components for the purposes of calculation (Hambly 1991). The first causes a longitudinal expansion, which is normally released by the articulation of the structure; the second causes curvature which leads to deflection in all beams and reactant moments in continuous beams, while the third causes a set of self-equilibrating set of stresses across the cross-section.The reactant moments can be calculated and allowed-for, but it is the self- equilibrating stresses that cause the main problems for prestressed concrete beams. These beams normally have high thermal mass which means that daily temperature variations do not penetrate to the core of the structure. The result is a very non-uniform temperature distribution across the depth which in turn leads to significant self-equilibrating stresses. If the core of the structure is warm, while the surface is cool, such as at night, then quite large tensile stresses can be developed on the top and bottom surfaces. However, they only penetrate a very short distance into the concrete and the potential crack width is very small. It can be very expensive to overcome the tensile stress by changing the section or the prestress。

Lesson 77 A successful operation一阅读课文The mummy of an Egyptian woman who died in 800 B.C. has just had an operation. The mummy is that of Shepenmut who was once a singer in the Temple of Thebes. As there were strange marks on the X-ray plates taken of the mummy, doctors have been trying to find out whether the woman died of a rare disease. The only way to do this was to operate. The operation, which lasted for over four hours, proved to be very difficult because of the hard resin which covered the skin. The doctors removed a section of the mummy and sent it to a laboratory. They also found something which the X-ray plates did not show: a small wax figure of the god Duamutef. This god which has the head of a cow was normally placed inside a mummy. The doctors have not yet decided how the woman died. They feared that the mummy would fall to pieces when they cut it open, but fortunately this has not happened. The mummy successfully survived the operation.二单词解析(一)lastVerb1.(过程、活动、状态)持续,继续Childhood seems to last forever. 童年似乎永不终结。

新概念二77课课文

新概念二77课课文第77课在上一课中,我谈到过不同城市的魅力,而这一课的主题则是关于我个人对大自然的喜爱和热爱。

在现代快节奏的城市生活中,我总是迫切地渴望能够远离喧嚣,放松身心,在大自然中尽情享受宁静与美妙。

首先,让我描述一下我充满热情的野外露营体验。

这是个让我彻底远离城市生活的机会。

我会带上帐篷、睡袋和一些生活必需品,然后选择一个美丽的自然场所搭建我的临时家园。

当夜幕降临,天空的星星们像闪耀的钻石般灿烂。

我被大自然的美景所吸引,仿佛置身于一个完全不同的世界。

我能够近距离观察到各种野生动物,细细聆听着鸟儿的鸣叫声,感受着微风轻拂抚摸皮肤的温暖。

整个过程都让我感到无比舒缓和放松,同时也让我更加珍惜大自然的美丽与宝贵。

其次,我对山脉和海洋的喜爱是不言而喻的。

徒步登山是一项有趣而刺激的活动,让我能够亲临大自然的壮丽景色。

在攀爬山峰的过程中,我会感受到身体的努力和挑战,但同时也能欣赏到高山上的宁静与美丽。

当我站在山顶,俯瞰下方的风景时,我感到一种难以言表的满足和充实感,仿佛我已经征服了世界一样。

另一方面,海洋的魅力是深埋在我心底的。

每当我踏上沙滩,迎接着蓝色的海浪拍打在脚下,我就觉得自己完全融入了这个广袤的海洋世界。

我喜欢涉足海水中,感受水滴在身上流动的感觉,沐浴在阳光下的温暖。

和海洋为伴的时刻让我远离了城市的喧嚣,感受到真正的自由与宁静。

最后,我想说一下大自然给予我们的启示和教育。

我相信,我们可以从大自然中学到很多东西。

例如,看着风吹拂树叶,我们可以学到适应变化的能力;观察蜜蜂忙碌工作,我们可以学到勤奋和毅力;凝视星空,我们可以感受到人类在宇宙中微不足道的存在。

大自然是一个无尽的教室,充满了无限的智慧,只要我们愿意,就能够从中不断学习与成长。

总之,我对大自然的喜爱和热爱是无法用语言来描述的。

无论是野外露营、徒步登山还是远离城市的海滩,我都能够感受到大自然带给我内心深处的宁静与美好。

与此同时,大自然也是一个庞大且无私的教师,它向我们展示了生命和世界的奥秘。

英译汉原文

英译汉原文英译汉原文:GlobalizationA fundamental shift is occurring in the world economy. We are moving rapidly away from a world in which national economies were relatively self-contained entities, isolated from each other by barriers to cross-border trade and investment; by distance, time zones, and language; and by national differences in government regulation, culture, and business systems. And we are moving toward a world in which barriers to cross-border trade and investment are tumbling; perceived distance is shrinking due to advances in transportation and telecommunications technology; material culture is starting to look similar the world over; and national economies are merging into an interdependent global economic system. The process by which this is occurring is commonly referred to as globalization.Correspondent: Globalization has been one of the most important factors to affect business over the last twenty years. How is it different from what existed before? Companies used to export to other parts of the world from a base in their home country. Many of the connections between exporting and importing countries had a historical basis. Today, to be competitive, companies are looking for bigger markets and want to export to every country. They want to move into the global market. To do this many companies have set up local bases in different countries. Two chief executives will talk about how their companies dealt with going global. Percy Barnevik, one of the world’s most admired business leaders when he was Ch airman of the international engineering group ABB and Dick Brown oftelecommunications provider Cable & Wireless.Cable & Wireless already operates in many countries and is well-placed to take advantage of the increasingly global market for telecommunications. For Dick Brown globalization involves the economies of countries being connected to each other and companies doing business in many countries and therefore having multinational accounts.Dick Brown: The world is globalizing and the telecommunications industry is becoming more and more global, and so we feel we’re well-positioned in that market place. You see currency markets are more global tied, economies are globally connected, more so nowadays with expanded trade, more and more multinational account s are doing business in many, many more countries. We’re a company at Cable & Wireless now, well-positioned to carry the traffic and to provide the services to more and more companies that now need to get to five countries or twelve countries, we’re often there.Correspondent: When Percy Barnevik became head of the international engineering group ABB, his task was to make globalization work. He decided to divide the business into over a thousand smaller companies. In this way he believed the company could be both global and local. In answering the question “How do you make globalization work?”, Percy Barnevik describes the “global glue” that keeps the many different people in ABB together. He then looks at the need to manage the three contradictions of company: it is decentralized but centrally controlled, it is big and small at the same time and it is both global and local.Percy Barnevik: We have now for ten years after our big merger created a “global glue” where people are tied together,where they don’t internally compete, but support each other, and you have global leaders with global responsibility and your local managers working with their profit centers, and if you have the right, so to say, agenda for these people and the right structure, you can use a scale of economy and your advantages of bigness but being small. We used to say you have three contradictions: decentralized and still centrally controlled, big and small, global and local, and, of course, to try to make these contradictions work together effectively, then I think you have a big organizational competitive edge.Correspondent: Globalizations can bring advantage to a business, but how does a company go global? Dick Brown mentions three ways companies can achieve “globalness”. Firstly, comp anies can work together in alliances. Secondly, they can acquire or buy other companies, and thirdly they can grow organically by expanding from their existing base.Dick Brown: Well, as you go global, and a handful or more of companies are going to really push out, in my view, to be truly global companies, and some of them, maybe all of them, will also work to be local. They’ll be local in chosen markets and global in their ability to carry their customers’ needs from continent A to continent B. We want to be one of the companies that’s both global and local. Alliances are one way to be global, it’s not the only way to be global; you can acquire your way to “globalness”, you can organically grow your way to “globalness”, you can have alliances which help you get global quicker, so you take your pick.Percy Barnevik: You have to start from the top with local people who understand language, culture and so on, and I think in this global world where the East is coming up now, that’s awinning recipe.Correspondent: ABB already found the winning recipe. Its theory of globalization has become the company’s working practice. So how do you make theory work in practice? Percy Barnevik believes that successful globalization involves getting people to work together, overcoming national, cultural barriers and making the organization customer-driven.Percy Barnevik: You see the easy thing is to have the theory, but then to make the systems work, to make people really work together, to trust each other — Americans, Europeans, Asians, to get over these national cultural barriers and create a common glue, ABB, and then make them customer-driven. If you can achieve that, and create that culture deep down then I think you have an important competitive edge.Correspondent: What Dick Brown and Percy Barnevik have shown is that there are different routes to globalization and that companies have to work hard to succeed in going global. Actually one of the disadvantages of the Global Strategy is that integrated competitive moves can lead to the sacrificing of revenues, profits, or competitive positions in individual countries —especially when the subsidiary in one country is told to attack a global competitor in order to convey a signal or divert that competitor’s resources from anoth er nation. The challenges managers of transnational corporations face are to identify and exploit cross-border synergies and to balance local demands with the global vision for the corporation. Building an effective transnational organization requires a corporate culture that values global dissimilarities across cultures and markets.。

附件2:外文资料翻译原文Title: On the 'long-term equity investment' criteria forchanges in its level of return of listed companies Abstract:Comparison of the 'long-term equity investments'norms and 'investment' criteria, 'internationalnorms' of the similarities and differences, on thisbasis, further analysis of the 'long-term equityinvestments' accounting changes on the level ofearnings of listed companies in China. Keywords:'long-term equity investment' criteria for a comparativeanalysis of the level of returnThe Ministry of Finance on February 15, 2006 enactment of the 'Accounting Standards No. 2 - long-term equity investments' (hereinafter referred to as' long-term equity investments' criteria) and the January 1, 1999 since the implementation of the' Accounting Standards for Enterprises - Investment '(hereinafter referred to as' investment' criteria) are very different, these differences are manifested in what areas specifically? 'Long-term equity investments' norms and 'International Accounting Standards' the existence of differences? And 'long-term equity investments' accounting method change is the ability to affect China's listed companies, the level of return? These are practical profession and the sector is concerned, this paper on these issues accordingly.1, 'long-term equity investments' norms and 'investment' criteria for a comparative analysis of January 1, 1999 implementation of the 'investment' criteria from February 15, 2006 changed its name to 'long-term equity investment' criteria, short-term equity investments, long-short-term bond investments entirely by 'Accounting Standards for Enterprises No. 22 - Tools to identify and measurement 'provisions. With the 'investment' criteria for the provisions relating to long-term equity investments compared to 'long-term equity investment' criteria has undergone many changes, the main differences between the performance of specific aspects as follows: 1, the investment classification of contrast'Long-term equity investment' criteria for investment is divided into: (1) Investment companies have been able to invest in units in the control of long-term equity investments; (2) units of the invested enterprise to be invested with a common control or significant influence of long-term equityinvestments; (3 ) invested enterprises invest in units of being do not have a common control or significant influence, and there is no active market quotations, fair value can not be reliably measured long-term equity investments; (4) invested enterprises invested units do not have a common control or significant influence, and there are quotations in an active market, fair value can be reliably measured long-term equity investments. The 'investment' criteria for investment is divided into: short-term (stocks or bonds) investment, long-term equity investments and long-term bond investment [1] 194. Can be seen, 'long-term equity investment' criteria according to the specific circumstances of long-term equity investments and further made a detailed classification, which requires companies should be different types of long-term equity investment in the appropriate accounting methods were used. In this way, long-term equity investment in the reliability and relevance of accounting information greatly increased.2, the follow-up measurement method equity investment compared'Long-term equity investments' Guidelines: For the above (1), (3), two types of investment and subsequent measurement using the cost method, for paragraph (1) class-controlled long-term equity investments in the preparation of consolidated financial statements, in accordance with the equity method adjustments; above (2) in long-term equity investments using the equity method follow-up measurement; above (4) classes of long term equity investment by the 'Accounting Standards for Enterprises No. 22 - Financial Instruments Recognition and Measurement', respectively, a division of 'trading financial assets' or 'available for sale financial assets'. The 'investment' criteria for the relevant provisions are: (1) does not control and does not have a significant impact on long-term equity investments accounted for using the cost method; (2) control or have a significant impact on long-term equity investments accounted for using the equity method; (3) measured in accordance with the cost of short-term investments, dividends received write-down investment costs. [1] 2073, long-term equity investment in contrast to the initial measurement'Long-term equity investment' criteria require that: (1) new business from the merger of long-term equity investment in the determination of the initial investment cost, if the same under the control of mergers, according to owner's equity accounted share of book value; if the same non - under the control of mergers, it should be according to 'Accounting Standards for Enterprises No. 20 - Business Combinations' identified in the merger accounted for at cost, that is, an exchange transaction ?٠ realized merger, the merger cost of the purchase date the purchaser to obtain being purchased party control of the assets to pay, the occurrence or assumed liabilities and equity securities issued by the fair value; ?ڠexchange transactions through multiple-step to achieve a business combination, merger costs and the costs of each individual transaction; ?Buy side took place for the conduct of a business combination of the direct costsassociated should also be included in the cost of a business combination; ?ܠmerger contract or agreement that may affect the future of the cost of the merger agreement matters, the purchase date if the estimated future events are likely to occur and the right the amount of the cost impact of the merger can be reliably measured, the purchaser should be included in integration costs. (2) In addition to a business combination to form a long-term equity investment approach, other methods (such as cash payments, issuing equity securities, an investor, the exchange of non-monetary assets and debt restructuring, etc.) should be achieved in the fair value of long-term equity investment recorded. The 'investment' criteria with the relevant provisions are: the cost of long-term equity investments were determined according to the following three conditions: ?٠ to obtain long-term equity in cash when the actual payment of the full purchase price as the cost of investment, but does not include the payment of the price has been included in yet to receive cash dividends declared; ?ڠ to abandon the non-cash assets (excluding equity) achieved long-term equity, investment cost in order to give up non-cash assets to determine the book value; ?The original equity method accounting for long-term equity investments at cost method to change accounting, or change the original using the cost method of accounting under the equity method when the carrying value of the original investment as the investment cost. [1] 202-204 we can see from the provisions of the two criteria, 'investment' criteria for mergers not covered by the long-term equity investment approach.4, the equity method of long-term equity investment initial investment, overflow, recognition of discount contrast'Long-term equity investments' Guidelines: Long-term equity investment of the initial investment costs and investment in units should have been the fair value of identifiable net assets of a share of comparison, the current is greater than the latter, those who do not adjust the initial investment in long-term equity investments cost; present when the person is less than the latter, the difference should be included in current profit and loss, while adjusting the cost of long-term equity investments. Equity accounting for long-term equity investment equity investment is no longer recognized the difference. The 'investment' criteria with the relevant provisions are: long-term equity investment, initial investment costs and should have been invested unit share of the net book value of assets to compare the current were greater than the latter, the difference should be included in equity investment difference and amortized in future periods; the current person is less than the latter, the difference recognized as capital reserve. [1] 210 5, the equity method of long-term equity investments recognized investment income compared'Long-term equity investments' Guidelines: In accordance entitled to, or share of the investee's share of net profit or loss realized to confirm the long-term investment gains and losses and adjust the book value of equityinvestments. However, in order to obtain investment-invested enterprises should invest in unit when the fair value of identifiable assets, based on the investee's net profit adjusted for confirmation. The 'investment' criteria for the relevant provisions: In accordance entitled to, or share of the investee's share of net profit or loss realized to confirm the long-term investment gains and losses and adjust the book value of equity investments. [1] 2116, long-term equity investment impairment provision for comparison'Long-term equity investments' Guidelines: cost accounting method, in an active market does not offer fair value can not be reliably measured long-term equity investments, impairment should be in accordance with 'Accounting Standards for Enterprises No. 22 - Financial Instruments Recognition and Measurement' in that the processing, that is, according to the book value of the present value of the difference between the provision for impairment losses and impairment can not be reversed; other in accordance with 'Accounting Standards for Enterprises No. 8 - Impairment of assets' and that the processing has been provision for the reduction value may not be reconverted. The 'investment' criteria with the relevant provisions are: impairment can be reversed, but reversal of the amount shall not exceed the number of its accrual [1] 212.2, 'long-term equity investment criteria' and 'International Accounting Standards' A Comparative AnalysisThe international guidelines on investment are: 'International Accounting Standards No. 25 - Accounting for Investments',' International Accounting Standards No. 28 - Accounting for Investments of the joint venture '; the United Kingdom' Standard Accounting Practice Bulletin No. 1 -- Joint Venture Accounting 'and' Financial Reporting Standard No. 2 - A subsidiary of the accounting '; Canada's' Canadian Institute of Chartered Accountants Handbook' Cap 2010 s, 3050 s; Australia's' Australian Accounting Standard 1006 guidelines - joint ventures' and 'Australian Standard 1016 guidelines - Joint Venture Investment'; region 'Financial Accounting Standards No. 5 - a long-term equity investment accounting standards'; China, Hong Kong's' Standard Accounting Practice No. 10 - Joint Venture Accounting processing 'China's 'long-term equity investments' guidelines on the content of the basic converging International Financial Reporting Standards, where only the International Accounting Standards, for example, a comparative analysis of 'long-term equity investment guidelines' and 'International Accounting Standards' major differences. The main difference between the two lies in processing and impairment of investment in joint venture accounting methods. (1) Impairment of long-term equity investment deal with comparative analysis. China's long-term equity investment impairment related to the treatment, such as the aforementioned, I am not elaborated; while the 'International Accounting Standards No. 25 - Accounting for Investments' requirement is due to a permanent fall in long-term investment value of the impulse of its book value reduction shall be creditedto the income statement, when the value of the investment pick-up or down the reasons ceased to exist, has been offset against the carrying amount to be allocated [2] 85. (2) joint venture investment accounting methods comparison. 'Long-term equity investments' Guidelines on joint ventures should be accounted for using the equity method, while the 'International Accounting Standards No. 31 - Financial Reporting Interests in Joint Ventures' requirement is that for joint venture investments in order to proportionate consolidation method mainly but can also be accounted for using the equity method [2] 111.3, long-term equity investments accounting for changes in the level of earnings of listed companiesAs mentioned earlier, 'long-term equity investments' norms and 'investment' criteria relevant for long-term equity investment compared to the biggest change is that the cost of local law and the scope of equity method of accounting, as well as the equity method, the withdrawal of the equity investment difference and merger spreads and other subjects, and fully reflects the fair value of assets purchased. For the equity investment deal with the difference, 'long-term equity investments' norms and 'Guidelines No. 38 - the first implementation of the Enterprise Accounting Standards' the following specific requirements: ?٠pairs of related enterprises to obtain a result of a merger or acquisition of long-term equity investments, according to book value confirmed that the cost of long-term investments, the actual price paid and the book value of the difference directly recognized as current income. ?ڠpairs of non-associated enterprises to obtain a result of a merger or acquisition of long-term equity investments, according to the actual payment of the cost to confirm the initial price of long-term equity investments. ?the first execution, according to equity method accounting for long-term investment, for related enterprises, yet the difference between amortization and completion of equity investment should be in full write-off, and adjust the retained earnings to offset the difference between equity investment after the balance of long-term equity investments as the first book identification of the cost of meeting its day. ?ܠ For non-affiliated enterprises, there is the difference between equity investment credit should be offset the difference between the lender to adjust retained earnings, and to offset the difference between the lender after the book balance of long-term equity investments as the first identification of the cost of its day; there is a debit balance of the equity investment, long-term equity investment should be the first of its day-book balance of the cost of the identification. Can be seen, long-term equity investment accounting method changes the impact on listed companies is mainly reflected in the net assets and profits of two aspects of future periods.1, on net assets.For the first time implementation, the difference between affiliatedenterprises or non-affiliated enterprises invest in equity investments in both the credit balance of the difference between the net assets affected. In order to evaluate the long-term equity investments may change in accounting methods listed net assets of the degree of influence, we used (difference between the combined equity investment spread) / equity (referred to as EQ indicator) to reflect the criteria for adjusting the degree of influence of different companies. Passed, we found that a larger EQ indicator in the top 10 companies, EQ values are more than 30%, if the difference comes from equity investment associated with acquisitions, it will significantly reduce the company's net assets, specifically in the following table 1 [ 3].Table 1 the difference between equity investments and merger spreads of total shareholder's equity (EQ) the ratio of the top 10 companies Company Name equity Total (million) ?٠ merger spreads equity investment balance (million) ?ST Yun 49.47468 million 94.60%ST Fenghua 2,177,818,169 83.43%Zhangjiajie 2,315,814,286 61.69%ST Daying 66,873,501 52.35%ST Jia Paper 140,767,073 50.25%Star-US joint 5,877,729,326 49.89%G Chong Hing 2,875,112,056 41.93%G * ST Universal 3,976,015,055 37.86%G Jin cast 17,794,056,410 31.70%Baiyun Mountain A 72940 22032 30.21%Source: Wande information, synthesis of Ping An Securities2, the profits of future periods affected.After the abolition of the difference in the equity investment will no longer need to carry out the difference between equity investment amortization, thus affecting the net profit of the enterprises. Equity investment difference debit balance, the net profit will increase, whereas net profit will be reduced. In order to evaluate the long-term equity investment accounting method changes on future periods profits of listed companies, the degree of influence, we used (difference between the combined equity investment spread) / net profit (abbreviated EP indicators) to reflect the criteria for adjusting the degree of influence of different companies. By calculating, we find that a larger EP indicators in the top nine companies, EP values are greater than 800%, if we assume that the difference between the original equity investment or merger spread according to 20-year amortization, net change would be likely to reach more than 50% Of course, the impact of the specific situation of still life and whether or not specifically from its amortization associated with mergers and acquisitions, see Table 2 [3].

According to statistics, A-share listed companies, there are 571 listed companies, there is the difference between equity investments and merger spreads the balance of the total A-share companies more than 40%, of which two have a combined negative 92, if the implementation of new guidelines the difference between equity investment write-off and merger spreads out, then the company's future net profits will fall significantly during the period, while the remaining 479 listed companies in the future will be able to significantly increase net profit.In summary, the new 'long-term equity investments' guidelines have been significantly closer to International Financial Reporting Standards, though, 'the merger difference' and 'equity investments' adjustment will affect the level of most of the benefits listed, but long-term interests of the , the new requirements of the Code will allow the value of listed companies to be more fairly reflect the financial information is more comparable, more conducive to investment decision-making.。
