通过有限元分析计算，设计人员在设计阶段就能了解到构件的应力、应变及位移，同时可以方便地对构件作反复修改，达到优化结构的目的。

These boastings have always shocked me, for I reverence love as the noblest of the passions, and it is impossible for me to conceive how one who has truly fallen victim to its benign influence can ever thereafter speak flippantly of it.

这些自夸之词令我震惊，因为我把'爱情'视为一种高贵的激情，对之深怀敬畏。再者说，一个曾真正堕入'爱情'之温柔陷阱的人，此后又如何能反复轻率地谈论它呢，这对我来说简直不能想像。

Because one need to search H in the range of 110, 1 and calculate the autocorrelation function many times, the concise formula of autocorrelation function of discrete fractional Gaussian noise is used to improve the processing speed. Simulation results have shown that it can estimate H accurately and more effectively than conventional LMS based on autocorrelation ftinction for both pure fractal signal and noise-corrupted fractal signal.

But circumstances inside the Wang Jia Wei film displays one kind sometimes all in linearity time going over and future hanging to purchase state , that often is able to point out solar terms in event beginning in image "hooligan formal biography " in famous show opening,"Chongqing tells the sum the "east evil west is poisonous to the date relapse in forest "" despite of he uses detail to go to emphasize the time concept unceasingly,these stories that he gives an account of and not special time background, they may may happen within this city corner every day, They whip the specimen being away from out in life only from the city But that you only are capable to do some detail discovering two stories is each other alternative in fact , Wang Jia Wei uses this to play hide-and-seek coming to bring about one kind of synchronic sex effect dyadic game if you had looked at "Chongqing forest " carefully,chance and nothing order having shown the present age city life now that the linearity time concept having dispeled tradition narrating is protruding, the intention having formed one kind of dyadic spirit of existentialism thereby accumulates, Wang Jia Wei applying on space is more than time benefits by associating together, If you have looked at Wang Jia Wei's work but have moved, that is by no means since are what the overall world impression initiates, but being resonance because of detail, is fragmentary as well as atmosphere called up by the subjective soliloquy that the garrulity spends can let you produce mental conception makes

王家卫电影里的场景往往都在线性时间的过去和未来中呈现出一种悬置状态，尽管他不断地用细节去强调时间概念，像《阿飞正传》里那个著名的开场、《重庆森林》里对日期的反复诉说和《东邪西毒》里经常会在事件开头指出节气，但他讲述的这些故事并没有特别的时间背景，它们可能每天都会发生在这个城市的角落里，它们只是从城市生活中抽离出来的标本。如果你仔细看过《重庆森林》，你就会发现两个故事的某些细节其实是互相交错的，王家卫用这种捉迷藏式的游戏来造成一种共时性的效果，既消解了传统叙事的线性时间观念又凸现了当代都市生活的偶然和无序，从而形成了一种存在主义式的精神意蕴，而王家卫在空间上的运用更是与其时间相得益彰，如果你看了王家卫的作品而感动的话，那绝不是由于整体世界的印象所引发的，而是因为细节、片断以及絮语化的主观独白所唤起的气氛能让你产生心领神会的共鸣使然

There was an increasing demand for engine power due to industrial development. As early as the 2nd century BC, the ancient Greeks invented an engine that was powered by the reaction from spurting steam; in 1690, the Frenchman Barben invented the first piston steam engine. On the basis of his predecessors' work and with his own hard work and numerous trials and failures, James Watt invented the steam engine with connecting rod, flywheel and centrifugal speed governor in 1782.In 1784, the British government granted a patent to James Watt for producing steam engines, which signified that man had entered the age of the steam engine and also significantly expedited the beginning of the Industrial Revolution in 18th century Europe. By the 1830s, steam engines had been widely used in various sectors such as textile, metallurgy, coal mining and transportation; for example, the American Robert Fulton invented the steamboat and the Englishman George Stephenson invented the steam locomotive.

随着社会的进步，社会由农业时代进入工业时代后，对全用手工操作已十分不满足，人们随着工业发展对动力的需求日益突出，瓦特在前人研究蒸汽的基础上，甚至早在公元前二世纪，古希腊人创造的一种利用蒸汽喷射的反作用的发动机，以及1690年法国人巴比首先发明第一台活塞式蒸气机等，刻苦钻研，反复实验，经历无数次挫折和失败，终于在1782年发明了具有连杆、飞轮和离心调速器的双动作蒸气机，使之成为了可以实用的蒸气机。1784年英国政府授予瓦特以制造蒸气机的专利证书，这标志着人类进入了蒸气机时代，有力地促进了欧洲18世纪的产业革命。

The study has shown:(1) With increasing sediment depth and the woody giblets, the total organic carbon, the extraction of benzene , the total humic acids and the unhydrolyte are enhanced, while the hydrolyte is decreasing.(2) According to the GC-MS analysis, n-alkane,n-alkan-2-ones and n-alkanones are composed mainly of long-chains,such a result is thought to be characteristic of a herbaceous input from 2300a.B.P. n-alkanones exist in the samples may be considered as the evidence of microorganisms activity.(3) It is showed that the lipids is more sensitive to the climate change than the floristic. The proxy of the pollen spore of the peat stratum is different from the normal environment proxy. It is one of the main reasons that the sensitivity difference of the bog vegetation reacting to the climate isn't accordant with the log of the fat molecule fossil and biology fossil.(4) The transformation of the peat organic carbon is under the influence of temperature,acidity,organic material constituting, etc, and it showed the up-trend with the depth. In the short-term scale, the conversion of the peat organic carbon is effected by seasonal water,regional climate and vegetations; while in the long-term scale, it is controlled mainly by the climate.(5) According to the comparing the orderliness of organic compound,vegetation giblets with the depth to the characteristics of the peat molecule fossil with the section, in the development of this peatmire, 1500a B.P（210cm）is regard as the borderline of the late Holocene, the keynote of the front period is warm with several cold fluctuations, and the trend of the back period is dry and cold although there were several fluctuations.

研究表明：（1）随深度的增高及植物残体中木本残体的增多，总有机碳、苯萃取物、总腐植酸、不被水解物含量逐渐增高，而易水解物含量减少；（2）GC- MS分析显示，正构烷烃，直链烷基2-酮和正烷醇均以长链组分为主，揭示了该泥炭柱剖面2347a.B.P的母源输入以草本植物为主；甲基酮类和短链正烷醇的存在是微生物活性很大的生物证据；（3）通过有机分子标志物与孢粉、植物残体等指标的对比研究表明：脂类化合物对气候变化的反映要比植物种灵敏得多，不同沼泽植物对气候变化的敏感性的差异是脂类分子化石记录与生物大化石结果很难一致的主要原因之一；（4）泥炭有机碳的转化受到温度、酸度、有机物质组成等很多因素的影响，短时间尺度，泥炭有机碳的转化受季节性降水、地方气候和植被等因素的影响；长时间尺度，泥炭地有机碳的转化，受气候条件控制；（5）总结泥炭分子化石特征、泥炭有机质各组分含量及植物残体组成随深度的变异规律，分析结果显示该泥炭地层形成过程中，1500a B.P（210cm）可作为划分前后晚全新世的界线，前期的基调是气候偏暖，但又有几次偏干冷气候的反复，后期气候以干冷为主，其间虽有几次上升波动，但整体趋势不变。
