科技英语 Genetically modified foods
This far-flung outrage took aim at genetically modified crops. But the protests backfired: all the destroyed plants were conventionally bred. In each case, activists mistook ordinary plants for GM varieties.
原因不难理解。世界上已有4400万公顷土地(相当于台湾面积的12.3倍)种植了基改作物,可是从某个角度来看,那些作物都是隐形的。植入农作物的基因,你一个也看不见、尝不出、摸不着,或察觉它对环境的影响。光凭外观,你无从知道含有外源基因的花粉粒是否会毒害蝶儿,或是传播到几公里外使其他植株受精。最令人担忧的正是它的“隐形”。基改作物究竟如何影响环境?我们何时才会注意到这些影响呢?
It's easy to understand why. In a way, GM crops-now on some 109 million acres of farmland worldwide-are invisible. You can't see, taste or touch a gene inserted into a plant or sense its effects on the environment. You can't tell, just by looking, whether pollencontaining a foreign gene can poison butterflies or fertilize plants miles away. That invisibility is precisely what worries people. How, exactly, will GM crops affect the environment-and when will we notice?

微囊包封相变材料在节能混凝土墙体上的应用摘要本文章研究一种在热方面使用相变材料的新型混凝土,最终目标是研发一种在建筑上能够起到节能的产品。
现在的工作是建筑两个尺寸的混凝室作为实验装置,以研究相变材料的夹杂物在26摄氏度的熔化点下的影响,混凝室是在西班牙当地建造的。
这个研究的结果表明了使用封装相变材料墙体能量的储存情况,与不用相变材料的传统混凝土相比,前者改善了热惯性,并且有较低的内部温度。
关键字:建筑,相变材料,热能量储存,节能,混凝土1、绪论热贮备是能量守恒的一个重要方面,这主要归因于热能的合理利用,对于垃圾焚烧和工业过程中产生的余热的有效利用,还有对工业废热发电和太阳能的越来越多的利用。
对太阳能的利用要求一个有效的热储存,因此,对太阳能的利用要想成功,很大程度上,依赖于能量储存的方法。
早在1980年以前,相变材料就曾经被考虑用作建筑上的热储备。
随着相变材料在石膏板、熟石膏、混凝土和其他材料墙体上的实现,热储备将会成为建筑结构的一部分甚至包括轻质建筑。
在文献中,开发和测试用来引导相变材料人造壁板和相变材料混凝土系统的模拟实验,以提高标准石膏人造壁板和混凝土块的热能储存能力,试验在峰值负载移位和太阳能利用上有特别的兴趣。
在过去20年中,一些大容量封装相变材料的窗体被用在主动或被动的太阳能利用上,包括直接获取。
然而,大多数封装商业产品的表面,在相变材料遭到太阳直接辐射熔化以后,会向建筑不恰当地释放热量。
相对地,建筑物的墙壁与天花板为建筑物每个区域的被动传热提供了大量的面积。
一些研究者针对饱和石膏人造壁板和其他使用相变材料的建筑材料做了调查,并描述了不同类型的相变材料以及它们的特性。
生产技术、热性能和已经注入相变材料的石膏人造壁板混凝土块的应用,已经在前面提到并且讨论过了。
相变材料必须被封装起来,这样就不会对结构材料的功能产生不利影响。
先前的试验使用了大容量封装或者宏封装,由于相变材料较差的传导性导致了试验的失败。

中国地质大学长城学院本科毕业设计外文资料翻译系别:工程技术系专业:机械设计制造及其自动化姓名:李旭学号: 052115032015年 3 月 5 日Introduction of MachiningHave a shape as a processing method, all machining process for the production of the most commonly used and most important method. Machining process is a process generated shape, in this process, Drivers device on the work piece material to be in the form of chip removal. Although in some occasions, the workpiece under no circumstances, the use of mobile equipment to the processing, However, the majority of the machining is not only supporting the workpiece also supporting tools and equipment to complete.Machining know the process has two aspects. Small group of low-cost production. For casting, forging and machining pressure, every production of a specific shape of the workpiece, even a spare parts, almost have to spend the high cost of processing. Welding to rely on the shape of the structure, to a large extent, depend on effective in the form of raw materials. In general, through the use of expensive equipment and without special processing conditions, can be almost any type of raw materials, mechanical processing to convert the raw materials processed into the arbitrary shape of the structure, as long as the external dimensions large enough, it is possible. Because of a production of spare parts, even when the parts and structure of the production batch sizes are suitable for the original casting, Forging or pressure processing to produce, but usually prefer machining.Strict precision and good surface finish, machining the second purpose is the establishment of the high precision and surface finish possible on the basis of. Many parts, if any other means of production belonging to the large-scale production, Well Machining is a low-tolerance and can meet the requirements of small batch production. Besides, many parts on the production and processing of coarse process to improve its general shape of the surface. It is only necessary precision and choose only the surface machining. For instance, thread, in addition to mechanical processing, almost no other processing method for processing. Another example is the blacksmith pieces keyhole processing, as well as training to be conducted immediately after the mechanical completion of the processing.Primary Cutting ParametersCutting the work piece and tool based on the basic relationship between the following four elements to fully describe : the tool geometry, cutting speed, feed rate, depth and penetration of a cutting tool.Cutting Tools must be of a suitable material to manufacture, it must be strong, tough, hard and wear-resistant. Tool geometry -- to the tip plane and cutter angle characteristics -- for each cutting process must be correct.Cutting speed is the cutting edge of work piece surface rate, it is inches per minute to show. In order to effectively processing, and cutting speed must adapt to the level of specific parts -- with knives. Generally, the more hard work piece material, the lower the rate.Progressive Tool to speed is cut into the work piece speed. If the work piece or tool for rotating movement, feed rate per round over the number of inches to the measurement. When the work piece or tool for reciprocating movement and feed rate on each trip through the measurement of inches. Generally, in other conditions, feed rate and cutting speed is inversely proportional to.Depth of penetration of a cutting tool -- to inches dollars -- is the tool to the work piece distance. Rotary cutting it to the chip or equal to the width of the linear cutting chip thickness. Rough than finishing, deeper penetration of a cutting tool depth. Rough machining and finishing machiningThere are two kinds of cuts in machine- shop work called, respectively, the "roughing cut" and the "finishing cut". When a piece is "roughed out", it is quite near the shape and size required, but enough metal has been left on the surface to finish smooth and to exact size." Generally speaking, bars of steel, forging, castings, etc. are machined to the required shape and size with only one roughing and one finishing cut. Sometimes, however, certain portions of a piece may require more than one roughing cut. Also, in some jobs, for example, when great accuracy is not needed, or when a comparatively small amount of metal must be removed, a finishing cut may be all that is required. The roughing cut, to remove the greater part of the excess material, should be reasonably heavy, that is, all the machine, or cutting tool, or work, or all three, will stand. So the machinist’s purpose is to remove the excess stock as fast as he can without leaving, at the same time, a surface too torn and rough, without bending the piece if it is slender, and without spoiling the centers. The finishing cut, to make the work smooth and accurate, is a finer cut. The emphasis here is refinement - very sharp tool, comparatively little metal removed, and a higher degree of accuracy in measurement. Whether roughing or finishing, the machinist must set the machine for the given job. He must consider the size and shape of the work and the kind of material, also the kind of tool used and the nature of the cut to be made, then he proceeds to set the machine for the correct speed and feed and to set the tool to take the depth of cut desired.Automatic Fixture DesignAssembly equipment used in the traditional synchronous fixture put parts of the fixture mobile center, to ensure that components from transmission from the plane orequipment plate placed after removal has been scheduled for position. However, in certain applications, mobile mandatory parts of the center line, it may cause parts or equipment damage. When parts vulnerability and may lead to a small vibration abandoned, or when their location is by machine spindle or specific to die, Tolerance again or when the request is a sophisticated, it would rather let the fixture to adapt to the location of parts, and not the contrary. For these tasks, Elyria, Ohio, the company has developed Zaytran a general non-functional data synchronization West category FLEXIBILITY fixture. Fixture because of the interaction and synchronization devices is independent; the synchronous device can use sophisticated equipment to replace the slip without affecting the fixture force. Fixture specification range from 0.2 inches itinerary, 5 pounds clamping force of the six-inch trip, 400-inch clamping force. The characteristics of modern production are becoming smaller and smaller quantities and product specifications biggest changes. Therefore, in the final stages of production, assembly of production, quantity and product design changes appear to be particularly vulnerable. This situation is forcing many companies to make greater efforts to rationalize the extensive reform and the previously mentioned case of assembly automation. Despite flexible fixture behind the rapid development of flexible transport and handling devices, such as backward in the development of industrial robots, it is still expected to increase the flexibility fixture. In fact the important fixture devices -- the production of the devices to strengthen investment on the fixture so that more flexibility in economic support holders.According to their flexibility and fixture can be divided into: special fixture, the fixture combinations, the standard fixture, high flexible fixture. Flexible fixture on different parts of their high adaptability and the few low-cost replacement for the characteristic.Forms can transform the structure of the flexible fixture can be installed with the change of structure components (such as needle cheek plate, Multi-chip components and flake cheek plate), a non-standard work piece gripper or clamping elements (for example: commencement standard with a clamping fixture and mobile components fixture supporting documents), or with ceramic or hardening of the intermediary substances (such as : Mobile particle bed fixture and heat fixture tight fixture). To production, the parts were secured fixture, the need to generate clamping function, its fixture with a few unrelated to the sexual submissive steps.According to the processing was part of that foundation and working characteristics to determine the work piece fixture in the required position, then need to select some stability flat combination, These constitute a stable plane was fixed inthe work piece fixture set position on the clamp-profile structure, all balanced and torque, it has also ensured that the work features close to the work piece. Finally, it must be calculated and adjusted, assembly or disassembly be standard fixture components required for the position, so that the work piece firmly by clamping fixture in China. In accordance with this procedure, the outline fixture structure and equipped with the planning and recording process can be automated control.Structural modeling task is to produce some stable flat combination, Thus, these plane of the work pieces clamping force and will fixture stability. According to usual practice, this task can be human-machine dialogue that is almost completely automated way to completion. A man-machine dialogue that is automated fixture structure modeling to determine the merits can be conducted in an organized and planning fixture design reduce the amount of the design, shortening the study period and better distribution of work conditions. In short, can be successfully achieved significantly improve fixture efficiency and effectiveness.Fully prepared to structure programs and the number of material circumstances, the completion of the first successful assembly can save up to 60% of the time.Therefore fixture process modeling agencies is the purpose of the program has appropriate documents.中文翻译食品机械加工工艺机械加工是所有制造过程中最普遍使用的而且是最重要的方法。
厨房清洁背后的科学力量作文
厨房清洁背后的科学力量作文英文回答:Kitchen cleaning is not just a mundane chore; it is backed by the power of science. Understanding the science behind kitchen cleaning can help us effectively remove dirt, bacteria, and other contaminants, ensuring a safe and hygienic environment for food preparation.One important aspect of kitchen cleaning is understanding the chemistry of cleaning agents. Different cleaning agents have different chemical compositions, which determine their effectiveness in removing different typesof dirt and stains. For example, dish soap contains surfactants that break down grease and oil, while bleach contains chlorine that kills bacteria and disinfects surfaces. By understanding the chemical properties of cleaning agents, we can choose the right products for specific cleaning tasks.Another scientific aspect of kitchen cleaning is the importance of temperature. Heat can enhance the cleaning power of certain agents. For instance, hot water can help dissolve grease and oil more effectively. Additionally, high temperatures can kill bacteria and other microorganisms. This is why we often use hot water when washing dishes or cleaning countertops. On the other hand, cold water can be effective for removing certain stains, such as chocolate or blood, as it helps prevent the stain from setting.Furthermore, the physics of cleaning plays a role in kitchen cleaning. The physical action of scrubbing or wiping helps to dislodge dirt and bacteria from surfaces. The friction created by scrubbing breaks the bond between the dirt and the surface, allowing it to be easily removed. This is why we often use scrub brushes or sponges when cleaning pots, pans, or countertops. Additionally, the absorbent properties of materials like paper towels or microfiber cloths help to soak up spills and remove moisture, preventing the growth of bacteria.In summary, the science behind kitchen cleaning involves understanding the chemistry of cleaning agents, the impact of temperature, and the physics of cleaning actions. By applying this knowledge, we can effectively remove dirt, bacteria, and other contaminants from our kitchens, ensuring a safe and clean environment for food preparation.中文回答:厨房清洁不仅仅是一项乏味的家务,它背后有着科学的力量。

淀粉科学实验的作文
淀粉科学实验的作文英文回答:Starch Science Experiment.In this science experiment, I investigated the effects of different variables on the properties of starch. I hypothesized that the type of starch, the concentration of starch, the temperature of the starch solution, and the presence of other solutes would all affect the viscosity, clarity, and gel strength of the starch solution.To test my hypothesis, I conducted a series of experiments in which I varied one variable at a time while keeping the other variables constant. I used different types of starch (cornstarch, potato starch, and wheat starch), different concentrations of starch (1%, 5%, and 10%), different temperatures (room temperature, 50°C, and 100°C), and different solutes (sugar, salt, and oil).I found that the type of starch, the concentration of starch, the temperature of the starch solution, and the presence of other solutes all had a significant effect on the properties of the starch solution.The type of starch affected the viscosity, clarity, and gel strength of the starch solution. Cornstarch producedthe highest viscosity, followed by potato starch and then wheat starch. Cornstarch also produced the clearest solutions, followed by potato starch and then wheat starch. Wheat starch produced the strongest gels, followed bypotato starch and then cornstarch.The concentration of starch affected the viscosity, clarity, and gel strength of the starch solution. Thehigher the concentration of starch, the higher the viscosity, the lower the clarity, and the stronger the gel strength.The temperature of the starch solution affected the viscosity, clarity, and gel strength of the starch solution. The higher the temperature of the starch solution, thelower the viscosity, the higher the clarity, and the weaker the gel strength.The presence of other solutes affected the viscosity, clarity, and gel strength of the starch solution. Sugar increased the viscosity and clarity of the starch solution, but decreased the gel strength. Salt decreased theviscosity and clarity of the starch solution, but increased the gel strength. Oil had no effect on the viscosity or clarity of the starch solution, but decreased the gel strength.中文回答:淀粉科学实验。
红薯面磨粉工艺流程
红薯面磨粉工艺流程英文回答:The process of making sweet potato flour involves several steps. First, the sweet potatoes are harvested and cleaned to remove any dirt or debris. Then, they are peeled and washed to ensure that only the flesh of the sweet potatoes is used. The peeled sweet potatoes are then cutinto small pieces to facilitate the drying process.After cutting, the sweet potato pieces are blanched in boiling water for a short period of time. This helps to remove any residual dirt or impurities and also softens the sweet potato pieces, making them easier to grind into flour. The blanched sweet potato pieces are then drained andcooled before proceeding to the next step.Once cooled, the sweet potato pieces are spread out on trays or racks and dried in a drying chamber or under the sun. The drying process can take several hours or even days,depending on the drying method used and the moisture content of the sweet potato pieces. The goal is to reduce the moisture content of the sweet potato pieces to a level where they can be easily ground into flour.After drying, the sweet potato pieces are ground into a fine powder using a grinding machine or mill. The resulting sweet potato flour is then sifted to remove any larger particles or impurities. The flour is then packed into bags or containers for storage or further processing.中文回答:制作红薯面磨粉的过程包括几个步骤。

The drying experiment is carried by the designed dryer, from the setting-to-work test, the design was success.Keywords: Microwave control system, microwave dryer, microwave drying, microwave power generatorINTRODUCTIONHoneysuckle is a traditional Chinese herbal medicine commonly used in China (Li, 1991); modern medical research shows that other than detoxification it also has antibacterial, antiviral, antipyretic, anti-inflammatory, hepatoprotective, hemostatic,antioxidant, immune regulation and so on. More and more pharmacological effects of honeysuckle were found, the market demand for honeysuckle is also a substantial increase. However, honeysuckle are saved after dried, honeysuckle drying process has become a hot research. Chen and Du (1997) studied hot air circulation drying process of honeysuckle and found that the drying effect using a higher temperature and high drying speed is better than a lower temperature and a long time drying, photogenic acid content is relatively low using hot air circulation drying and the medicinal value is small. Microwave drying effect is much better than the other drying methods by comparing the experimental result (Geng and Ge, 2013; Geng et al ., 2013). Microwave drying apparatus used in drying honeysuckle process is not reported because of the high cost of microwave apparatus. Microwave drying apparatus is designed based on microwave drying experimental results; and find the microwave drying conditions and the best process route on honeysuckle in this study. METHODOLOGY The whole structure and principle of microwave dryer:The whole structure of microwave dryer: The wholestructure of the apparatus is designed to be annulus according microwave drying process and basic principles of microwave drying honeysuckle and has structure compact, footprint small, material handling convenience and ease of continuous production. The microwave drying apparatus is assembled mainly by microwave generator, microwave dryer, dehumidifyingsystems, control system, transmission systems, microwave leakage inhibited mechanism and other components, shown in Fig. 1.The components design:The microwave generator: The microwave generator consists of a magnetron (2M210-M1 Panasonic), high-voltage transformer (700E-1 (AL)), high-voltage diodes (HVH-12) high-voltage capacitor (CH85 1.0 μF ±3% 2100VAC 50/60 HZ -10/85 internal discharge resistor,fuse (8A250V SICHERUNG FUSE). The microwave generator function is to generate microwave, honeysuckle is in high temperature under the microwave affecting and then play the effect of drying. The energy transport mechanism: The energy transport mechanism is to ensure the transmission of microwave energy. According to the distribution characteristics of microwave energy (Chen et al ., 1993), the apparatus is designed similar car headlights (Fig. 2); the role of the headlamp reflector is that gathered radiation from a point in a limited taper angle and produce a high luminous intensity. The design can make the microwave distribute uniformly and the drying effect is better. The design of microwave drying chamber: Since microwave energy are more concentrated in the dryingchamber, materials heating is rapid, especially for sheetmaterials heating and drying, therefore waveguide type drying chamber is selected. Designed ring-shaped tunnel microwave dryer made from galvanized tin, the upper wall opened a coupling port for inputting microwave; both sides of the upper wall has two rowsFig. 1: The whole structure figure of annulus microwave dryer1: Microwave drying zone; 2: The left microwaveleakage control mechanism; 3: Material handing area;4: The right microwave leakage control mechanism; 5:The microwave dryer framework; 6: Inverter motor; 7:Transmission systems; 8: Microwave dryer; 9:Waveguide mounting plate; 10: Parabolic waveguideassembly; 11: Microwave generator; 12: Microwavegenerator installation; 13: Cover; 14: DehumidifyingsystemsFig. 2: Shape of the energy transport mechanismof apertures for discharging moisture; in the middle sidewall provided with an observation window for observing the internal running (Wang, 2004). The microwave dryer size is designed according to size and volume of honeysuckle and how to make the electric field evenly distributed and drying efficiency. The drying efficiency determines the maximum size, the size and volume of honeysuckle and the uniformity of the electric field determine the minimum size under normal circumstances.Material transmission system: Honeysuckle transmission trays are set in the bottom of the microwave drying chamber, rubber roller is supported in the bottom of tray and located by the inner circular orbit guide wheel, the tray is driven by motor and frequency control of motor speed is used according to the thickness of honeysuckle and microwave power. Dehumidifying system: Air humidity inside the drying chamber is an important factor affecting drying efficiency. Vapor from honeysuckle is discharged continuously in drying process, if not discharged promptly the vapor from the chamber, it will reduce the drying efficiency and the discharged humidity is to be set thus can improve drying efficiency. Holes are opened the inner wall with 10 rows, 3 mm diameter and center distance of 8 mm. ventilation is installed outside the drying chamber and prevent condensation of water back, both preventing microwave leakage and ensuring the vaper discharged smoothly.The microwave leakage control mechanism:The microwave leakage control mechanism is disposed at both ends of the microwave dryer, the microwave leakage control mechanism installed in order to avoid harm to the human. The home heating microwave oven and industrial microwave drying apparatus leakage is stipulated as follows: at 50 mm distance from the apparatus, the microwave power cannot exceed 500 mW/mm2(2450 MHz) (Wang, 2004). The microwave leakage control mechanism of microwave drying apparatus is used hybrid-type mechanism (Zhang and Hong, 1999); suppressor is composed by comb-type attenuator and added absorbed material in the end.The principle of microwave dryer: Fresh honeysuckle contains a lot of water; the water molecules rub strongly in a very short time at sufficiently high frequency under the microwave effect, make the molecular motion increase, the temperature rise and while water in fresh honeysuckle evaporated in form of vapor. Surface temperature is slightly lower than temperature of the inner layer due to evaporative cooling, at the same time the heat is generated in honeysuckle and the vapor is formed continuously, so that pressure gradient is formed. Water in honeysuckle is discharged under impacting of pressure gradient, which is microwave drying principle (Hatibaruah et al., 2013).MICROWAVE DRYER PERFORMANCEANALYSISThe same mass with same quality is taken; drying fresh honeysuckle using different drying methods (natural drying, coal drying and microwave drying), then determined of photogenic acid content (Huang et al., 1996). The results are shown in Table 1.Table 1 shows that content of photogenic acid is the highest in microwave drying, the content of photogenic acid is higher in coal drying,and the content of photogenic acid is minimum.Table 1: Content of photogenic acid in different drying methods Drying method Sample No.Content of photogenic acid(peak area/peak height) Natural drying 16536318/383243 Coal drying 2 8913332/518366 Microwave drying 3 9671787/567369CONCLUSIONThe annular microwave dryer can be used for drying fresh honeysuckle and can realize continuous production, improved production efficiency and clean.A parabolic waveguide is used in microwave dryer, microwave distribution is more uniform in microwave dryer.REFERENCESChen, C.M. and G.X.

外文翻译专业过程装备与控制工程学生姓名于亮亮班级 B装备032班学号 0310140146 指导教师咸斌.甘薯粉丝和面机对称蜗管进口的实验室研发Bingtao Zhao, Henggen Shen, Yanming Kang翻译:于亮亮摘要:设计三种具有不同几何形状进口的甘薯粉丝和面机,一种是传统的单一切向进口(CTSI),一种是对称的直蜗管进口(DSSI),还有一种是对称的收敛蜗管进口(CSSI)。
进口类型对甘薯粉丝和面机工作特性的效果,包括收集效率和压降,本文研究并比较其与粒子大小和流速的关系。
实验结果表明对称的蜗管进口(SSI),尤其是CSSI形状进口,随着新增的可忽略压降的条件下越来越多的对收集效率有重要的影响。
另外,收集效率和压降的研究结果也包括试验数据和理论模型之间的比较。
关键字:甘薯粉丝和面机;对称的蜗管进口;收集效率;压降。
⒈介绍:甘薯粉丝和面机广泛应用于空气污染控制领域,为含悬浮微粒气体进行气–固分离等工业应用[1]。
由于其制造简单,操作成本低,和对极端的苛刻条件的适应性好,因此无论是应用在工程上还是操作过程上甘薯粉丝和面机成为最主要的除尘装置之一。
然而,越来越多的提倡环境保护,气–固分离都强调应该分离出最大量的微尘粒子。
为达到这个要求,甘薯粉丝和面机几何学和性能的改善要比替换可更换件来得重要。
许多专家认为扩大旋风室是提高甘薯粉丝和面机性能的主要因素,通过引进新设计的进口与操作变量。
这包括对一台分离试样的甘薯粉丝和面机的装有多个进口叶片的分馏器的测试并结合其他的研究[2],德奥特建立一个数学模型来预算小型圆柱多谐振荡器甘薯粉丝和面机的收集效率[3],穆尔和麦克法伦以莱普勒的典型几何学为基准测试一个有多个进口的甘薯粉丝和面机[4],高塔姆和斯蒂纳斯设计和测试一个可换气的多进口甘薯粉丝和面机取样器的最小方向偏差[5],通过分离后的清洁空气来比较一个双进口甘薯粉丝和面机的性能[6]。
在本文中,介绍了一些形状研究员设计的不同形状进口的新式进口,和它们对甘薯粉丝和面机的性能效果的实验性研究。
⒉试验性的研究三种具有不同几何形状进口的甘薯粉丝和面机,包括传统的单一切向进口(CTSI),对称的直蜗管进口(DSSI),和对称的收敛蜗管进口(CSSI),已经研制出了。
它们的几何形状和尺寸见Fig1和Table⒈为了测试不同的进口类型所带来的效果,其它的尺寸设计完全相同,仅进口的几何形状不同。
Fig.1 甘薯粉丝和面机形状示意图:(a) Model A 传统的单一切向进口 (b) Model B对称的收敛蜗管进口 (c) Model C 对称的收敛蜗管进口。
.Table 1:甘薯粉丝和面机尺寸统计:(单位mm)Fig.2:试验结构系统示意图图⒉所示为实验系统机构。
压降是由接在甘薯粉丝和面机进口和出口管的两压力计测量的。
通过一数字微压计(SINAP ,压差1000-IIIC )读得。
收集效率是通过微颗粒大小分析器(SPSI,LKY -2)所得粒度分布计算的。
由于Model B,C具有一样对称的进口,所以组合式甘薯粉丝和面机各进口的流速是相等的。
并且流速可由阀来控制;运行条件也相同,将浓度为5.0g/m3的粒子用双喷管螺旋给料机喂到进口管中。
固体颗粒为滑石粉核心密度的2700kg/m3,按原标准尺寸分配,平均直径的5.97Am,几何偏差为2.08。
在这次测试过程中平均大气压,环境温度,和相对湿度分别是99.93kPa,293K,75%。
⒊结果和讨论3.1 收集效率图3显示所测量的甘薯粉丝和面机总效率与流速或者进口速度的关系。
正如预料的那样收集效率随进口速度的增加而增加。
然而,Model B Model C两甘薯粉丝和面机有着对称的蜗管进口,在同一进口速度下,两者的总效率永远要高于传统的单一切向进口甘薯粉丝和面机(Model A),特别是有CSSI的甘薯粉丝和面机(Model C)的总效率最高。
在测试给定的相同速度条件下,通过改善进口几何形状所带来的甘薯粉丝和面机总效率的增加率分别为0.15–1.15%和0.40–2.40%。
图4(a)–(d) 比较不同进口类型的甘薯粉丝和面机的分级收集效率。
在进口速度分别为11.99,16.04,20.18,和23.85m/s时的流速分别为388.34,519.80,653.67,和772.62 m3/h。
可见,甘薯粉丝和面机的摩擦效率随粒子大小的增加而增加。
所有甘薯粉丝和面机的分级收集效率曲线都呈S形。
DSSI(Model b)和CSSI(Model c)甘薯粉丝和面机的摩擦效率分别比CTSI甘薯粉丝和面机(Model a)大2–10%,5–20%。
这表明进口的几何形状对甘薯粉丝和面机的收集效率有着重要的影响。
进入有对称的蜗管进口的甘薯粉丝和面机(Model B和C)的粒子容易聚集在甘薯粉丝和面机壁上,因为粒子只能移动很短的位移,尤其CSSI(Model C)改变了粒子分布浓度并使粒子在进入甘薯粉丝和面机的筒体前就从气体中分离了出来.图5根据传统的理论[7–11]比较了流速为653.67m3/h(进口速度为20.18m/s)时的试验数据。
很明显,以Mothes /Loffler模型Iozia/ Leith 理论得出的效率曲线比其它的学说所得的曲线更符合试验结果。
这些结果与研究进行经过Dirgo、Leith 和Xiang 等人的研究结果相吻合。
Fig.3 不同进口速度下甘薯粉丝和面机的总效率比较表明有些模型可以推断一个还没有公开的理论结果。
但是现有的试验数据理论还不足以推断出流态和粒子浓度分布的变化是对称的蜗管进口对甘薯粉丝和面机性能产生的效果。
为了更清楚地验证对称的蜗管进口对甘薯粉丝和面机性能的作用效果,再看图6,表示随着流速或进口速度的变化引起的各个模型的50%切截尺寸。
在相同进口速度下model c和model b的50%切截尺寸比model a要低。
与进口速度的减少一样,50%切截尺寸也是近似呈线性减少的。
例如,当进口速度为20.18m/s时,50%切截尺寸的减少率由model b的9.88%和model c的24.62%决定。
这表明新型进口可以促进甘薯粉丝和面机的收集效率。
3.2.压降甘薯粉丝和面机得压差数值通常表示为一定数量的气体入口速度压头高度差,用压差数值系数表示,压差数值系数是进口动压压差数值的分度。
表2列出了在不同的入口速度时这三个甘薯粉丝和面机的压差数值系数值。
显然,甘薯粉丝和面机的压降高低与流速高低有关。
然而,一定流速或者入口速度下,A、B和C模式的压力降系数有所不同,在5.21和5.76之间变化,其平均值为5.63。
例如模式B在5.22–5.76之间变化,平均值为5.67;模式C在5.16–5.70之间变化平均值为5.55;模式A根据回归分析计算。
这是一个重点,因为由此有可能在没有有效的压差值增加的情况下提高气旋收集效率。
表3列出了压降的试验数据与电流理论的比较结果。
结果显示Alexander和Barth 模式与试验数据最符合,尽管Shepherd ,Lapple 和Dirgo 气旋模式推算也很出色。
Fig.4 不同进口速度时的选粉效率等级:(a)进口速度为11.99 m/s (b)进口速度为16.04 m/s (c) 进口速度为20.18 m/s (d) 进口速度为23.85 m/s.Fig.5 试验所得效率等级与理论的比较50%切截尺寸Table 2 :甘薯粉丝和面机的压力损失系数:Table 3 :与理论压力损失系数比较:4、结论人们发明了一种具有对称的蜗管进口(SSI),DSSI和CSSI的新型甘薯粉丝和面机,并且测试和比较了这种进口类型的甘薯粉丝和面机的性能。
实验结果显示这种DSSI甘薯粉丝和面机和CSSI甘薯粉丝和面机的总效率分别比CTSI甘薯粉丝和面机高出0.15–1.15%和0.40–2.40%。
此外,DSSI甘薯粉丝和面机、CSSI甘薯粉丝和面机和CTSI甘薯粉丝和面机的压力损失系数分别是5.63、5.67和5.55。
尽管这些并联进口增加了甘薯粉丝和面机的复杂程度并加大了其成本,然而具有SSI尤其是CSSI的甘薯粉丝和面机具有更好的收集效率,而且显著的减少了压力损失。
这篇文章介绍了借助于改进进气道几何形状设计而改善甘薯粉丝和面机性能的可能性。
