“比较测量法”在三线摆实验中的应用

摘要

This paper discusses the reason why the traditional method to measure ＂third-line pendulum inertia＂ experiment produces greater error.Besides,on the basis of the original experiment,it makes some improvement and puts forward the new measuring method-＂comparison measurement＂,and also expounds the details by using the error theory.%探讨了＂三线摆法测转动惯量＂实验在传统测量方法上产生较大误差的原因,对原实验的测量方法进行了改进,提出了新的测量方法——＂比较测量法＂,并运用误差理论作了较为详细的阐述。
