摘要
对竖直振动的弹簧系统进行了理论分析,得出振动频率与弹簧自身质量及振子质量的关系满足tan〔(m1/k)～1/2ω〕(m1/k)～1/2ω=m1/m2,在弹簧的固定点用力传感器对力的变化进行了测量,实验结果与理论分析相一致.
The frequency of an oscillator with a spring of finite mass is derived to satisfy tan tan（√mi/kω）√mi/kω=m1/m2 in the gravity. The force at the fixed point of the vertical spring is measured by a force sensor, its frequency isin agreement with the value obtained from our theoretical analyses.
