Based on the entropy theory and Dempster - Sharer evidential theory, the problems of information fusion in mechanical characteristic parameter and mechanical failure diagnosis ware studied.

利用信息论熵的相关理论和D-S证据理论，分别研究机械特征参数提取和机械故障诊断的信息融合问题。

The results show that the amorphous PLGA fiber with porous structure (0.1-1.0 μm) is obtained by diluted solvent spinning method and the mechanical properties is affected by pressure and temperature. Bending strength and shearing strength of the samples increase firstly and then decrease with the increase of molding temperature and pressure. While the molding temperature is 160℃and the pressure is 105MPa, the PLGA materials possess optimal mechanical properties, bending strength, shearing strength and bending modulus 187.3 MPa, 100.0 MPa and 2.5 GPa, respectively. The mild temperature molding PLGA materials are desired to play a grate role in non-bearing internal fixation devices.

研究结果表明：非晶多孔结构的PLGA纤维可通过溶液沉析纺丝的方法获得，其孔径为0.1~1.0μm；压制压力和压制温度对材料的力学性能影响较大，材料的抗弯强度、剪切强度和抗弯模量均随着温度和压力的增大而先增大后降低；在压制压力为105MPa，压制温度为160℃时，试样的力学性能比较理想，此时，其抗弯强度可达到187.3MPa，剪切强度达到100.1MPa，抗弯模量达到2.5GPa，可望作为非承重部位骨折愈合内固定材料。

There was on his face an expression of solemn and holy rapture, as if he were revealing to me the mysteries of his religion. I became far more interested in him than in the socks. I looked at him in amazement."My friend," said I,"if you can keep this up, if this is not merely the enthusiasm that comes from novelty, from having a new job, if you can keep up this zeal and excitement day after day, in ten years you will own every sock in the United States." My amazement at his pride and joy in salesmanship will be easily understood by all who read this article. In many shops the customer has to wait for someone to wait upon him. And when finally some clerk does deign to notice you, you are made to feel as if you were interrupting him. Either he is absorbed in profound thought in which he hates to be disturbed or he is skylarking with a girl clerk and you feel like apologizing for thrusting yourself into such intimacy. He displays no interest either in you or in the goods he is paid to sell. Yet possibly that very clerk who is now so apathetic began his career with hope and enthusiasm. The daily grind was too much for him; the novelty wore off; his only pleasures were found outside of working hours. He became a mechanical, not inspired, salesman. After being mechanical, he became incompetent; then he saw younger clerks who had more zest in their work, promoted over him. He became sour. That was the last stage. His usefulness was over. I have observed this melancholy decline in the lives of so many men in so many occupations that I have come to the conclusion that the surest road to failure is to do things mechanically. There are many teachers in schools and colleges who seem duller than the dullest of their pupils; they go through the motions of teaching, but they are as impersonal as a telephone.

他的脸色庄严而虔诚，就像是在向我透露他的信仰中的奥秘似的我对他远远超过了对袜子的兴趣我吃惊地打量着他"我的朋友，"我说，"如果你能这样保持下去，如果这热情并不仅仅缘于新奇，缘于找到份新工作，如果你能日复一日地保持这种热心和激情，不出十年，全美的每一双袜子都将是从你手中卖出去的"我对他推销时的自豪与欣喜所感到的诧异，读者诸君当不难理解在很多店铺，顾客不得不等待有人来招呼当终于有个售货员肯屈尊理你，那样子又让你感觉像是打扰了他他不是陷于讨厌被人搅扰的深思之中，就是和女售货员嬉戏调笑；而你不适时的插入打断了他们的亲昵，为此你感觉好像需要道歉似的他显示出对你和他拿着工资去卖的东西毫无兴趣然而，就是这样一个如此冷漠的售货员，或许当初也是满怀希望和热情开始工作的天天枯燥乏味的苦差事令他不堪忍受，新鲜感磨去了，惟一的乐趣只能在工作之外找到他成了一个机械的没有干劲的售货员机械呆板之后便是笨拙无能随后，看到比他年轻工作热情比他高的售货员得到了提拔，在他之上，他于是变得烦躁刻薄此时便到了他职业生涯的最后阶段他不再有用了我观察到，很多职业中的太多人在人生道路上都有这种可悲的堕落由此我得出结论：机械地应付差事是离失败最近的路大中小学里的许多教师，似乎比他们最最迟钝的学生还要呆滞；他们似乎也搞搞教学，却毫无人的感情，就如同一部电话机

There was also ice-type trap that has its own CD, a fire trap type has its own CD, now did not materialize, DZ down the trap speed was a lot faster, you may also have their own snow, I feel that the survival of LR should be the introduction of mechanical traps, and before this is not magic-type traps were CD, and talents from the survival of deep point out that the characteristics of mechanical trap is triggered only once, the effect of the main tactics, such as an elastic traps, and the task: I would like to bird eggs inside the elastic bed is similar to the trap of those who touch the vertical bounce as high as 20-30 yards, ex, yes, he has been in the air, hit two shots.

还记得以前有说冰类陷阱有自己的CD，火类陷阱也有自己的CD，现在都没有实现，DZ拆陷阱的速度倒是快了不少，可能暴雪也有自己的考虑，我觉得生存LR应该引入机械陷阱，这个不和之前的魔法类陷阱共CD，且由生存深天赋才能点出，机械陷阱的特点是只触发一次，战术效果为主，比如出现一个弹力陷阱，和任务：我要鸟蛋里面的弹力床相似，把触碰陷阱的人垂直弹起20-30码那么高，（恩，对，他在空中了，打两枪。

In particular, twin-screw-type air compressor is widely used in mechanical, metallurgical, power electronics, pharmaceuticals, packaging, chemicals, food, mining, textiles, transport, and other industrial fields, compressed air into the mainstream products air compressor, is to A standard atmospheric pressure of air through the transformation of the mode of energy output to meet the needs of users of air equipment, energy conversion generally be interpreted as mechanical energy to kinetic energy.

尤其是双螺杆式的空气压缩机被广泛应用机械，冶金，电子电力，医药，包装，化工，食品，采矿，纺织，交通等众多工业领域，成为压缩空气的主流产品空压机，就是把一个标准大气压的空气通过能量转化的方式输出来满足用户需求的空气的设备，能量转化一般都是可理解为机械能转为动能。

The main reason of resin fragmentation is mechanical stirring, so it is not suited for a reactor with a mechanical stirrer.

研究表明，机械搅拌对树脂催化剂破碎有很大的影响，因此，反应器中不宜有机械搅拌装置。

The microstructure of PE dispersed in polyamide matrix effects the properties of composites. PE spherulites are good for mechanical properties and sustention of water absorption. Checked PE has many cavities existed at the interface of PA and PE, resulting in decrease of mechanical properties and water absorption.

PE在PA基体中微观形态的不同导致了复合材料性能的差异，球状分布有利于材料的韧性增加，但吸水率降低很少；网状分布时，PE/PA两相间空隙较多，材料力学性能降低，但吸水率却大幅下降。

On the other hand,there still exit many negative aspects that restrict the promotion of international competitiveness of mechanical and electronic products after China entering WTO. First,with the reduction of tariff and non-tariff wall,the international competitive environment of mechanical and electronic products will be more and more severely.

本文从理论和现实两个视角来分析机电产品国际竞争力提升的内在机制：一方面，通过将比较优势和竞争优势理论、战略性贸易理论和产业内贸易理论的基本思想与当前的国际经济环境及时代背加入WT 0后中回机电产品国际无争力馒开分析景相结合，提出机电产品国际竟争力提升所需具备的产业和贸易政策：另一方面，通过实现机电企业的核心竞争力，来提升机电产品的国际竞争力。

"Each human infection constitutes an opportunity for genetic modification of the virus through reassortment, mutation, or both...."
