摘要
研究复摆钟在相对论运动下的钟慢效应和复摆钟发生钟慢效应的内在机制.结果表明,复摆钟整体沿水平方向运动的钟慢效应是因为动力学机制发生了变化;而沿垂直方向运动的钟慢效应,既与动力学机制的变化有关,也与运动学机制的变化有关.一般情况下,无论复摆钟朝什么方向运动,都将发生钟慢效应.两惯性系相对速度一定时,运动的复摆钟都比静止的钟慢了一个相同的因子.
Time dilation effect and the inherent of its mechanisms based on compound pendulum at relativistic motion are studied. The results of studying show that time dilation effect in horizontal motion of compound pendulum is a result of the change in mechanism of dynamics such as acceleration of gravity, such in vertical motion of compound pendulum is due to both the change in mechanism of dynamics and the change in mechanism of kinematics. Generally, the motion of compound pendulum as a whole moving along at any direction in an inertial frame has time dilation effect. And if the relative velocity of two inertial frames is constant, the compound pendulum in motion runs slower at a same factor than the resting one.
