摘　　要：利用DISLab研究弹簧振子简谐运动中力和位移随时间变化的关系,发现弹簧在振动过程中回复力存在滞后现象.本文通过设计实验,研究了弹簧的劲度系数、振子质量和振幅对回复力滞后的影响.The variations of restoring force and displacement in the harmonic vibration process of spring oscillator were studied using DISLab.Hysteresis of restoring force of the spring was found in the process of its vibration.Influences of the spring＇s stiffness coefficient,oscillator quality and amplitude on the hysteresis of restoring force were studied.

关 键 词：DISLAB 弹簧振子 回复力
