摘　　要：用混合法测定物质比热容中通常把高温物质放入低温的水中，这时损失大量的热量，增加了测量误差，为减少这部分误差，提出了把低温物质放进高温物质的实验方法和步骤。In the experiment of determining mass specific heat capacity by hybrid method, it is a usualpractice to put a high- temperature substance into low- temperature water, thus lossing a multitude ofheat and increasing error in determination. In order to decrease this error. the experimental method andprocedures are suggestd that low - temperature substance be put into high- temperature one.
