摘要
测量冰的熔解热实验涉及热学实验的若干基本内容，如混合量热法和孤立系 统、冷却定律和修正散热以及测温原理，具有热学实验绪论的性质。作者设计了 多组实验，不断改变实验条件来对冰的熔解热进行测量。本文在此基础上，对实 验数据进行了处理，分析了误差来源并对不同实验条件对实验过程产生的影响进 行了分析，并给出实验经验以及改进建议。

Abstract
Some of the fundamentals of ice melting heat measurement relates to thermal experiments, such as mixing calorimetry and isolated system, cooling law and modified cooling and temperature measurement principle, the nature of heat experiment. The author designed several experiments to measure melting heat of ice by changing the experimental conditions constantly. On this basis, the experimental data are processed, the error sources are analyzed, and the effects of different experimental conditions on the process are analyzed, and the experimental experience and suggestions are given.
