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。

The traditional mechanical lock is only a simple mechanical device.

传统的机械门锁仅仅是单纯的机械装置。

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
