非惯性系中单摆的振动周期

The Vibration Period of Simple Pendulum in the Inertialess Reference System

计算非惯性系中单摆的振动周期,一般的方法学生不容易接受。如果先求出非惯性系中单摆的平衡位置和平衡状态下的合力,再使“空间转换”,按惯性系列出单摆运动的微分方程,求出周期,效果很好。

For avoiding confusion, the vibration period of simple pendulum is discussed in two levels, first, the resultant forces of equilibium poison and equilibium state in the intertialess reference system are obtained, then, teh differential equation of simple pendulum is given and the period is obtained in the inertial reference system by 'space transformation'.
