摘要
用“类比法”引入一个新的物理概念——转动惯性线，并由此为定理在这类问题中的应用构划出一幅清晰的物理图象，使得对问题的分析求解显得十分简易．
Universally,there is lacking in imaginal understanding in theapplication of angular momentum theorem to the process that rigid body system rotate about fixed axis. In this thesis,a new physical concept is put forwardby means of anaIogy method that do is rotating inertia line. It not only describes a clear physical picture in the appIication of angular momentum theorem,but sometimes makes the solution to these problems easy as well.
