摘　　要：在普通物理实验中,测定空气比热容比的实验,已被许多先进的技术手段和方法所代替,实验误差可控制在较小的范围内.但在实际操作中,南方春季潮湿的空气,将给实验带来很大的误差.针对这种情况,对实验装置做适当改进,可以消除这种影响.并介绍测量空气比热容比的'超声法',以提高测量精度.In doing general physics expermenta tion,A lot of develope d technigue me asures has been introduce in the one of measuring air ratio of sp ecific heat'?'.The experiment error can be controlled in a small range.But in practical manipulation,the moist spring air in south will cause a large err or.To counter his cirsumstance,doing some approp riate improvement on experime nt device con eliminate his effect.In order to improve the precision of experim e nt,this article will introduce a method of how to use ultrasonic wave to meas ure air ratio of specific heat'?'.
