成形的

Among the many remarkable final projects that have been proposed and presented at the end of the course have been a Renaissance hourglass blown in the MIT glass shop and set into a frame turned on our set shop lathe; a four harness loom built by a student who then wove cloth on it; a number of chain mail tunics and coifs; a wide variety of costume and furniture pieces and electrified period lighting fixtures.

在以往的课程中，学生们构想并于期末展示出了很多优秀的作品，比如一个文艺复兴时期的沙漏，它是学生在麻省理工学院的玻璃工作坊吹制、并在我们布景工作坊的车床上成形的；一台由学生制作的四综纺织机，制作者真正用它来织布；许多锁子甲束腰外衣和头巾；各式各样的服饰、家俱和电气化时代的照明设备。

I saw when at his Word the formless Mass, This worlds material mould, came to a heap: Confusion heard his voice, and wilde uproar [ 710 ] Stood rul'd, stood vast infinitude confin'd; Till at his second bidding darkness fled, Light shon, and order from disorder sprung: Swift to thir several Quarters hasted then The cumbrous Elements, Earth, Flood, Aire, Fire, [ 715 ] And this Ethereal quintessence of Heav'n Flew upward, spirited with various forms, That rowld orbicular, and turnd to Starrs Numberless, as thou seest, and how they move; Each had his place appointed, each his course, [ 720 ] The rest in circuit walles this Universe.

我曾目见，这世界实质不成形的块块，在神的指点下就变成这许多东西。 '混沌'听从神的话，旷野的喧哗镇静下去，无边无垠的空间，也有了界限；到神第二次发言时，'黑暗'就逃走了， '光明'来临了，从混乱中产生了秩序。从此，地、水、火、风等粗笨的元素都赶快各就各位；同样地，天上轻灵的第五元素也以各种各样的形式产生出来，升到空中，滚成球形，正如你所看见的不可计数的星辰怎样运行。它们各有指定的地方，各有轨道，剩下的灵气，成了宇宙的城廓。

The research mainly focuses upon the unique deformation mechanism, forming method, quality control and parameter optimization, and the key technologies in Finite Element Analysis for the 3D Non-Axisymmetric thin-walled tube spinning. A CNC spinning equipment for the 3D Non-Axisymmetric thin-walled tube has been designed and manufactured based on the experimental investigation of the forming method.

The plastic deformation mechanism of the process is explained. The vector equations of the curved conical surface and the figure of the particle motion for the forming process of the bending tube are presented. The theoretical model of stress and strain fields of the forming process is deduced. The practical forming process of tubes of large diameter demonstrates the validity of the new type of design method of the ox-horned core bar and the computation formula of the length of the raw tube.

The stability of the interface between two-layer fiber flow is essential for getting high quality multi-formation and layer purity. Some measures of keeping the stability of interface are got from theoretical analyse. The measures is close reducing the velocity difference between two layers; putting the fiber of lower density on the upper layer and the fiber of relatively higher density on the lower layer; and using low pulsation pump as the pumping equipment.

两层叠加流动的界面稳定性对多层成形的质量及层间纯度有重要影响，本文通过采用小扰动法对流动界面的稳定性分析认为，减小层间速度差；把密度较大的纸浆置于下层，密度较小的纸浆置于上层；以及采用低脉冲泵作为上浆泵均有利于保持层间流动界面的稳定性。

The forming limit diagram relates to strain paths, then the forming limit diagram made in linear strain path can not be directly used to complex strain paths.

根据试验测定的不锈钢板材成形极限图用理论方法建立了不锈钢板材的成形极限应力图，其真实板材成形极限图和成形极限应力图均是一条直线，只有这样板材成形才能满足塑性变形体积不变条件。

American antitrust laws date from 1890, while many of the convincing explanations Dr. Xue offers were not developed in the economics literature until the second-half of the 20th Century. And while American courts have for some years now reshaped antitrust law to reflect this newer understanding, other nations' courts and regulators seem to want to stop the intellectual clock at about 1950, the highpoint of fallacious antitrust reasoning.

美国的反垄断法始于1890年，但兆丰所介绍的这些令人折服的解释，许多是到了20世纪后半叶才逐渐在经济学研究中成形的；而尽管美国的法院在过去这些年里已经开始重塑反垄断法，以求体现这些新知识，但其他国家的法院和管制者却似乎要让智力的时钟定格在1950年附近，而那恰恰是反垄断思维荒诞不经的高峰期。

The good news is that after formatting from the command line to FAT32 (format /fs:fat32 /a:4096 drive:) all but one of the problematic games that I tested work perfectly.

好消息是，从指挥线后格式化了FAT32(格式/曾荫权：了FAT32/答：4096年径：)所有问题，但其中的游戏测试工作，我很好。
