加速杆的相对论收缩
Relativistic contraction of an accelerated rod
摘要：
本文讨论了加速度和速度均沿杆长方向时，加速度作用下刚性杆任意一点的相对论运动。讨论包括一个时间相关的力施加到一个单一的点，以及一个时间无关的力沿杆任意分布的情况。杆的相对论长度的时间依赖性取决于力的作用点，但在加速终止后，最终的速度和长度不依赖于它。在匀加速杆上的观察者感觉到一个惯性力，它在加速方向上减小。定性地讨论了实际杆的非刚性对结果的影响。
英文摘要：
The relativistic motion of an arbitrary point of an accelerated rigid rod is discussed for the case when velocity and acceleration are directed along the rod's length. The discussion includes the case of a time-dependent force applied to a single point, as well as a time-independent force arbitrary distributed along the rod. The time dependence of the rod's relativistic length depends on the application point of the force, but after the termination of acceleration the final velocity and length do not depend on it. An observer on a uniformly accelerated rod feels an inertial force which decreases in the direction of acceleration. The influence of non-rigidity of realistic rods on our results is qualitatively discussed.
