These techniques fall ino two distinct classes, depending upon whether or not the shaft is also balanced as a rigid body.

这些方法可以分为明显的两类，决定于是否把轴作为刚体进行平衡。

Based on elastic FEM theory and heat transfer theory, the author USES I-DEAS software as a CAE tool, builds the finite element analysis method and techniques of the principle shaft system on work.

本文采用I - DEAS软件作为计算机辅助分析的工具，基于弹塑性有限元理论和传热学理论，建立了工作状态下主轴系统的有限元分析方法及技术处理方法。

If you're caught you will get sent to D-Block solitary, a tiny cube where days are marked by a light shaft travelling across the wall - or you might be interrogated using techniques only alluded to in the otherwise thorough Alcatraz audio tour, with first-hand accounts by prison guards and prisoners of the Rock.
