摘要
利用多普勒效应实验仪器测量垂直简谐振动的周期和频率实验中,对传统测量方法进行了改进,测量接收器悬挂弹簧后再加挂砝码时的弹簧的伸长量.采用2种方法进行实验,测量结果表明改进后的方法误差更小、更精确.
Vertical harmonic vibration was researched,its period and frequency were measured by the Doppler effect experiment instrument.The traditional method was improved by measuring the change in the length of the spring hung on the receiver with the increasement of weight.By analyzing two sets of data,it concluded that adopting the second method could come to a more accurate conclusion.The sources of error of the first method was also analyzed.
