摘要
在大学物理实验教材中常用音叉弦振动形成共振驻波来测量音叉的振动频率,但对其中的"二分频"现象无相关的理论解释,本文在建立与"二分频"现象相似的模型中,用数值计算的方法演示了这一结果。
The method of resonance of stationary wave by tuning fork bowstring vibration is always applied to measure the frequency in college experiment text.However,the theoretical interpretation of half frequency is not seen.This paper,by building the similar mold of half frequency,focuses on displaying the results by numerical methods.
