摘　　要：对音叉作受迫振动的规律及音叉振动周期与双臂质量的关系进行了研究,自制了新型的音叉受迫振动与共振实验仪,该仪器不仅可以手工调节做实验,而且可以实现计算机实时测量.The forced vibration of a tuning fork is studied,an experimental device is constructed and the dependence of resonance frequency to the mass of the arms of the fork is measured, the real-time measurement is realized.

关 键 词：音叉 受迫振动 共振 实时测量
