By means of finite element method, we analyze the stress distributing and fatigue state of tube mill hollow shaft of some factory applied self-produce FE soft ANSYS, provide the bases for estimating working circumstance of tube mill of running state.

利用有限元分析方法，应用自制的有限元软件ANSYS程序，对某厂管磨机出料中空轴的应力分布及疲劳状态进行分析研究，从而为判断运行状态中管磨机的工况提供依据。

The annular sealing member and inlet are provided with means to secure said sealing member to said inlet to prevent axial movement therebetween, said second sealing means engaging the outer curved surface of the tubular member whereby sealing engagement may be effected between the sealing member and the tubular member over a plurality of relative axial positions therebetween.

所述的第二密封装置与管形件的外曲面接合，借此实现密封件和管形件之间在多个相对轴向位置上的密封连接。

During ion source operating, alternating axial magnetic field and azimuthal electric field in discharge tube ionize hydrogen gas purified by hot palladium pipe, and form plasma. In fifties year, research reports studied on RF ion source are numerous however most of them are concerned about application, and research reports relevant to discharge theory or experiment model are unfrequent.

离子源工作时，放电空间交变的轴向磁场和涡漩电场激发放电管中经钯管纯化后通入的氢气电离，形成等离子体。50多年来，关于高频离子源的研究报告很多，但是，这些研究主要都集中在应用研究方面，有关高频无极环形放电离子源的理论与实验模型研究不是很多。

The results indicated that the density of microtubule and neurofilament increased and the increase interrelated with axonal cross section.

由于微管参与了轴浆转运的机制，微管的增加提示其在神经再生中起了重要的作用。

The centrosome is the classical site of microtubule nucleation and is thought to be essential for axon growth and neuronal differentiation--processes that require microtubule assembly.

中心体是微管核化的经典位置，并且轴突生长和神经分化都需要微管蛋白的组装核化。

In this dissertation, we purify,functionalize, and align the single-walled carbon nanotubes by Langmuir-Blodgett technique using compression-transfer method.

本文正是针对这一问题，对单壁碳纳米管进行了提纯、功能化，并利用LB技术的液面排布转移法实现了碳纳米管沿着轴向大面积定向排列。
