摘　　要：针对空气比热容比测定实验误差较大的现状,采取在设定测量准确度标准的前提下,先由理论值反推导出测量参考值,确定出测量值可取范围的实验方法,增强了实验可控制性,将操作误差减小到了最低限度;同时,使学生在科学思维和实验技能上得到充分地训练。According to the status of the larger error of air specific heat capacity ratio measurement ex- periment, the author proposed that the measurement reference value was can be firstly anti-deduced by the reference value. Under the premise of setting the measurement accuracy requirements, the desirable range of measured values was determined. This method enhanced experimental controllability, and the error was reduced to a minimum. At the same time, the students get adequate training in experimental methods and skills.
