摘要: 通过分析密立根油滴的受力情况和运动状态,确认在测量油滴做匀速运动一段确定距离的时间时,不必考虑油滴的加速过程.测量时间和平衡电压时应按顺序进行,先测量时间,后测量平衡电压.在一般情况下,如果油滴在受电场力的作用下15s内没有移动,可以认为仪器显示电压是平衡电压.

关键词: 平衡状态, 加速过程, 测量顺序, 初始条件

Abstract: When measuring the time for uniform moving a fixed distance, the accelerated access needs not be considered. There is a measuring order that firstly time, then equilibrium voltage. If the oil drop does not move within 15 s in general, the voltage on the apparatus should be the equilibrium voltage.

Key words: equilibrium state, accelerated access, measuring order, initial condition
