时也导致了船舶在波浪上的稳性特征值的变化。其中,船舶横摇恢复力矩作为保证 船舶安全的最为重要的参数受此变化影响最为严重。传统理论对船舶各个运动模态 的数值估计和预报是在船舶线性运动理论框架下进行的,适应于微幅运动,对于船 舶发生大幅度运动时所呈现强烈的非线性运动无法适用。参数横摇的存在揭示了船 舶海上客货安全和航行效率上存在的危险隐患.其影响强度是船舶频域幅值理念下 安全预报的盲区,因此正确预报船舶参数横摇的发生范围和危险程度势在必行。 1.1.2 研究目的

Hartwell)、英国伦敦皇家癌症研究基金会的保罗・纳斯(Paul Nurse)和提莫西・亨特(Timothy Hunt) 3位科学家, 以表彰他们发现了“细胞周期的关键调节因子”。

他们采用遗传学和生物化学的方法, 确定了在真核生物中控制细胞周期的两种因子: 细胞周期依赖性蛋白激酶(CDK)和细胞周期蛋白。

这一重大发现在生物学和医学的诸多方面具有重要的意义。

细胞是构成生物体的基本结构单位和功能单位。

细胞进行分裂是细胞生长的重要环节。

细胞通过细胞周期, 完成分裂, 进行增殖以繁衍后代。

细胞周期大致可分为4个时相, 即G1期、S期、G2期和M期。

细胞周期的不同时相具有高度精确的协调性, 细胞必须在完成上一次时相后才能进入下一次时相。

一个细胞周期结束, 不仅细胞数量增加为二, 而且将染色体准确无误地遗传给分裂出的子细胞。

这一过程的任何缺陷都将导致遗传信息的改变, 最终有可能导致癌变。

这3位科学家的研究工作有着一定的连贯性, 为揭示细胞周期调控的分子机理做出了共同的贡献。

哈特韦尔是最早关注细胞周期的人, 并试图探究其控制机理。

利兰・哈特韦尔(Leland H. Hartwell 1939—)1939年10月30日出生于美国洛杉矶。

在他10岁左右的时候, 就对一些事物有着强烈的好奇心, 常常采集动物标本像蝴蝶、青蛙、蛇和蜘蛛等, 了解一些他感兴趣的问题。

Standard Pump AssemblyNOTE:This exploded view is of a PVP 60/76. For all practical purposes it may be used as a guide to determine PVP Series components.Use of a Relief ValveThe use of a relief valve, while not mandatory is recommended in the main circuit to suppress hydraulic shock loads and adds additionalsystem protection.Fluid RecommendationsPremium quality hydraulic oil with a viscosity range between 150-250 SSU (30-50 cst.) at 38°C (100°F). Normal operating viscosity range between 80-1000 SSU (17-180 cst.). Maximum start-up viscosity is 4000 SSU (1000 cst.).NOTE:Consult Parker when exceeding 71°C (160°F) Inlet Fluid Temperatures. Oil shouldhave maximum anti-wear properties, rust and oxidation treatment.FiltrationFor maximum pump and system component life,the system should be protected from contamination ata level not to exceed 125 particles greater than10 microns per milliliter of fluid. (SAE Class 4/ISO16/13.) Due to the nature of variable displacement pumps, variations in pump inlet conditions, fluid acceleration losses, system aeration, and duty cycle we do not recommend suction line filters. We do recommend the use of a properly sized, in-tank, suction strainer. Contact your Parker representative for assistance.Start-UpOn initial start-up, the case should be filled with oil, pressure adjustments should be reduced and the circuit should be open to permit priming.Inlet ConditionsNot to exceed .17 bar (5 In. Hg.) Vacuum at 1800 RPM on petroleum base fluids. See recommended speed spectrum for specific inlet conditions.Shaft Rotation and Line UpPump and motor shaft alignment must be within.010 TIR maximum, using a standard floating coupling. Please follow coupling manufacturer’s recommended installation instructions to prevent end thrust on pump shaft. Turn pump to assure freedom of rotation. Pump and motor must be on a rigid base. The coupling should be sized to absorb the peak horsepower developed.Installation and MountingWhen mounting a PVP Series Pump, the “case drain”must be on top of the pump. The “case drain” should be a separate line unrestricted to the reservoir and extend below the oil level as far from the inlet lineas possible. The “case drain” line must not exceed .7 bar (10 PSI) back pressure. Suggested maximum line length is 10 feet.Special InstallationsConsult your Parker representative for any application requiring the following:Pressure above rated, drive speed above maximum, indirect drive, fluid other than petroleum oil, oil temperature above 71°C (160°F).Inlet PressureNot to exceed 1.72 bar (25 PSI).。

CONTROLEDGE PLCHoneywell’s PLC is part of the ControlEdge™ family, a next-generation family of controllers providing unprecedented connectivity through all levels of process and business operations. The result is optimized operations and maintenance efficiencies that liberate personnel from manual processes. ControlEdge PLC is one of the first controllers in the market to achieve Cybersecurity ISA Level 2 certification.NEW GENERATION CONTROLLERControlEdge PLC dramatically reduces configuration, integration, and support costs while decreasing risk with the best cybersecurity on the market. Honeywell is the first to provide a complete ecosystem including PLC, SCADA, and DCS together. Combined withExperion®, ControlEdge PLC minimizes downtime through unified support, and lowers total cost of ownership through extended system lifecycle and the best investment protection on the market. Experion and ControlEdge PLC leverage a common HMI platform, providefaster field device commissioning, and improve device diagnostics.Built-in OPC UA, EtherNet/IP, DNP3, Modbus, Profinet, MQTT protocol, and cybersecurity provide smooth integration to a range of instruments, equipment and software from multiple vendors. The first PLC to offer HART-enabled Universal I/O with optional redundancy configuration, providesremote configuration, late design change flexibility, and simulation for improved project implementation and training.HOW IS CONTROLEDGE PLC DIFFERENT?Experion IntegrationHoneywell can serve as your single vendor for all automation needs, including the DCS, PLC, Varaiable Frequency Drive, SCADA, Field Device Manager for asset management, and a Panel PC - all with seamless integration, configuration, and support.Coordination is easier with fewer teams and direct access to system knowledge, and auto-configuration of PLC data points in Experion Server means easy updates and faster project deployment. A single point of responsibility reduces both risk and cost with fewer coordination errors, less engineering, faster installation, less training and reduced hardware.Field Device Manager (FDM) provides fast and accurate commissioning of field devices and simplified diagnostics, resulting in fewer site trips. Combining FDM with the HART IP open standard offers design flexibility and protectionof existing site investments. HART command function blocks in the PLC support improved plant operation and device diagnostics, along with reduced commissioning and installation cost.Operator effectiveness is increased with a common HMI across system applications. An integrated solution provides pre-built diagnostics, anintegrated alarm summary, and history, trending and reporting on a single Experion infrastructure with native peer-to-peer integration to Experion Controllers. Results are fewer operator and engineering stations, less hardware and wiring, reduced IT licensing and training, fewer errors, and increased efficiency and availability. You benefit from reduced cost over the lifecycle with smaller footprint and easier maintenance. The Experion PPC (Panel PC), provides a touch user interface and consistent HMI for an operator either in the field or in the control room. Consistent interface alarms, trends, diagnostics and history results inbetter response and plant uptime.Lean Project Execution andUniversal I/OHoneywell’s lean project executionsolution provides several enhancements to the PLC.ControlEdge PLC offers a variety of I/O choices for flexibility and reduced system cost. HART-enabled Universal I/O means no additional costly hardware to support HART.

哈奇投资法则案例

哈奇投资法则案例

哈奇投资法则案例(最新版)目录1.哈奇投资法则简介2.哈奇投资法则案例分析3.哈奇投资法则的实际应用4.哈奇投资法则的优缺点正文1.哈奇投资法则简介哈奇投资法则,全称“哈奇投资组合优化法则”,是由美国著名投资专家威廉·哈奇(William H.Gross)提出的一种投资组合优化方法。

该法则主张通过分散投资来降低风险,同时追求较高的投资收益。

哈奇投资法则适用于各类投资者,包括个人投资者和机构投资者。

2.哈奇投资法则案例分析假设投资者有 100 万元,希望分散投资到股票、债券和现金三种资产中。

根据哈奇投资法则,我们可以通过以下步骤来构建投资组合:(1)确定各类资产的预期收益率和风险。

例如,股票的预期收益率为 8%,风险为 20%;债券的预期收益率为 4%,风险为 10%;现金的预期收益率为 1%,风险为 0%。

(2)计算每种资产的预期收益风险比,即预期收益率除以风险。

股票的预期收益风险比为 0.4,债券的预期收益风险比为 0.4,现金的预期收益风险比为 0.1。

(3)根据预期收益风险比,分配投资金额。

假设投资者希望获得 5% 的预期收益率,那么可以按照预期收益风险比,将 100 万元投资金额分配到股票、债券和现金中。

具体分配方案为:股票投资金额为(0.4/1.5)×100 万元≈26.67 万元,债券投资金额为(0.4/1.5)×100 万元≈26.67 万元,现金投资金额为(0.1/1.5)×100 万元≈6.67 万元。

3.哈奇投资法则的实际应用哈奇投资法则在实际应用中具有较高的灵活性。

投资者可以根据自己的风险承受能力、收益预期和市场环境,调整投资组合中的资产种类和比例。

同时,哈奇投资法则也适用于动态调整,投资者可以根据市场变化,及时调整投资组合,以保持投资组合的收益风险比稳定。

4.哈奇投资法则的优缺点哈奇投资法则的优点主要表现在:(1)简单易懂,便于投资者掌握和操作;(2)分散投资,有效降低投资风险;(3)追求较高投资收益,符合投资者利益。

HART-LEAP WELLTHE Knight had ridden down from Wensley MoorWith the slow motion of a summer's cloud,And now, as he approached a vassal's door,"Bring forth another horse!" he cried aloud."Another horse!"--That shout the vassal heardAnd saddled his best Steed, a comely grey;Sir Walter mounted him; he was the thirdWhich he had mounted on that glorious day.Joy sparkled in the prancing courser's eyes;The horse and horseman are a happy pair; 10 But, though Sir Walter like a falcon flies,There is a doleful silence in the air.A rout this morning left Sir Walter's Hall,That as they galloped made the echoes roar;But horse and man are vanished, one and all;Such race, I think, was never seen before.Sir Walter, restless as a veering wind,Calls to the few tired dogs that yet remain:Blanch, Swift, and Music, noblest of their kind, Follow, and up the weary mountain strain. 20The Knight hallooed, he cheered and chid them onWith suppliant gestures and upbraidings stern;But breath and eyesight fail; and, one by one,The dogs are stretched among the mountain fern.Where is the throng, the tumult of the race?The bugles that so joyfully were blown?--This chase it looks not like an earthly chase;Sir Walter and the Hart are left alone.The poor Hart toils along the mountainside;I will not stop to tell how far he fled, 30Nor will I mention by what death he died;But now the Knight beholds him lying dead.Dismounting, then, he leaned against a thorn;He had no follower, dog, nor man, nor boy:He neither cracked his whip, nor blew his horn,But gazed upon the spoil with silent joy.Close to the thorn on which Sir Walter leaned,Stood his dumb partner in this glorious feat;Weak as a lamb the hour that it is yeaned;And white with foam as if with cleaving sleet. 40Upon his side the Hart was lying stretched:His nostril touched a spring beneath a hill,And with the last deep groan his breath had fetchedThe waters of the spring were trembling still.And now, too happy for repose or rest,(Never had living man such joyful lot!)Sir Walter walked all round, north, south, and west,And gazed and gazed upon that darling spot.And climbing up the hill--(it was at leastFour roods of sheer ascent) Sir Walter found 50 Three several hoof-marks which the hunted BeastHad left imprinted on the grassy ground.Sir Walter wiped his face, and cried, "Till nowSuch sight was never seen by human eyes:Three leaps have borne him from this lofty brow,Down to the very fountain where he lies."I'll build a pleasure-house upon this spot,And a small arbour, made for rural joy;'Twill be the traveller's shed, the pilgrim's cot,A place of love for damsels that are coy. 60"A cunning artist will I have to frameA basin for that fountain in the dell!And they who do make mention of the same,From this day forth, shall call it HART-LEAP WELL."And, gallant Stag! to make thy praises known,Another monument shall here be raised;Three several pillars, each a rough-hewn stone,And planted where thy hoofs the turf have grazed."And, in the summer-time when days are long,I will come hither with my Paramour; 70And with the dancers and the minstrel's songWe will make merry in that pleasant bower."Till the foundations of the mountains failMy mansion with its arbour shall endure;--The joy of them who till the fields of Swale,And them who dwell among the woods of Ure!"Then home he went, and left the Hart, stone-dead,With breathless nostrils stretched above the spring.--Soon did the Knight perform what he had said;And far and wide the fame thereof did ring. 80Ere thrice the Moon into her port had steered,A cup of stone received the living well;Three pillars of rude stone Sir Walter reared,And built a house of pleasure in the dell.And near the fountain, flowers of stature tallWith trailing plants and trees were intertwined,--Which soon composed a little sylvan hall,A leafy shelter from the sun and wind.And thither, when the summer days were long,Sir Walter led his wondering Paramour; 90 And with the dancers and the minstrel's songMade merriment within that pleasant bower.The Knight, Sir Walter, died in course of time,And his bones lie in his paternal vale.--But there is matter for a second rhyme,And I to this would add another tale.PART SECONDTHE moving accident is not my trade;To freeze the blood I have no ready arts:'Tis my delight, alone in summer shade,To pipe a simple song for thinking hearts. 100As I from Hawes to Richmond did repair,It chanced that I saw standing in a dellThree aspens at three corners of a square;And one, not four yards distant, near a well.What this imported I could ill divine:And, pulling now the rein my horse to stop,I saw three pillars standing in a line,--The last stone-pillar on a dark hill-top.The trees were grey, with neither arms nor head;Half wasted the square mound of tawny green; 120 So that you just might say, as then I said,"Here in old time the hand of man hath been."I looked upon the hill both far and near,More doleful place did never eye survey;It seemed as if the spring-time came not here,And Nature here were willing to decay.I stood in various thoughts and fancies lost,When one, who was in shepherd's garb attired,Came up the hollow:--him did I accost,And what this place might be I then inquired. 130The Shepherd stopped, and that same story toldWhich in my former rhyme I have rehearsed."A jolly place," said he, "in times of old!But something ails it now: the spot is curst."You see these lifeless stumps of aspen wood--Some say that they are beeches, others elms--These were the bower; and here a mansion stood,The finest palace of a hundred realms!"The arbour does its own condition tell;You see the stones, the fountain, and the stream; 140 But as to the great Lodge! you might as wellHunt half a day for a forgotten dream."There's neither dog nor heifer, horse nor sheep,Will wet his lips within that cup of stone;And oftentimes, when all are fast asleep,This water doth send forth a dolorous groan."Some say that here a murder has been done,And blood cries out for blood: but, for my part,I've guessed, when I've been sitting in the sun,That it was all for that unhappy Hart. 150"What thoughts must through the creature's brain have past!Even from the topmost stone, upon the steep,Are but three bounds--and look, Sir, at this last--O Master! it has been a cruel leap."For thirteen hours he ran a desperate race;And in my simple mind we cannot tellWhat cause the Hart might have to love this place,And come and make his deathbed near the well."Here on the grass perhaps asleep he sank,Lulled by the fountain in the summer-tide; 160 This water was perhaps the first he drankWhen he had wandered from his mother's side."In April here beneath the flowering thornHe heard the birds their morning carols sing;And he, perhaps, for aught we know, was bornNot half a furlong from that self-same spring."Now, here is neither grass nor pleasant shade;The sun on drearier hollow never shone;So will it be, as I have often said,Till trees, and stones, and fountain, all are gone." 170"Grey-headed Shepherd, thou hast spoken well;Small difference lies between thy creed and mine:This Beast not unobserved by Nature fell;His death was mourned by sympathy divine."The Being, that is in the clouds and air,That is in the green leaves among the groves,Maintains a deep and reverential careFor the unoffending creatures whom he loves."The pleasure-house is dust:--behind, before,This is no common waste, no common gloom; 180But Nature, in due course of time, once moreShall here put on her beauty and her bloom."She leaves these objects to a slow decay,That what we are, and have been, may be known;But at the coming of the milder day,These monuments shall all be overgrown."One lesson, Shepherd, let us two divide,Taught both by what she shows, and what conceals;Never to blend our pleasure or our prideWith sorrow of the meanest thing that feels." 1901800.。
