摘要
化学反应焓变的测定是大学化学实验中的一个经典实验。本文对选取的60名学生的实验报告数据进行了分析,并结合教师在预备实验中发现的问题,对实验数据的误差进行了分析,并提出了实验设备的改进方法。
Determination of enthalpy change of chemical reaction is a classical experiment in university engineering chemistry experiment.data of 60 students'experimental reports were extracted and analyzed and combined with the problems found by the teachers in the preparatory errors of experimental data were analyzed,and the methods of experimental equipment improvement were proposed.
