非绝热情况下冰的溶解热的测定

Measurement of the Heat of Fusion of Ice in the Non-adiabatic Case

研究非绝热情况下精确测定冰的熔解热。与传统方法不同,测量时冰水混合物可以置于完全非绝热环境中。通过控制冰水混合物对环境的放热和从环境吸热相等来摒除环境对测量系统的影响。结果表明,通过选取合适的冰块质量、热水质量和温度三个基本要素,测量得到的冰的熔解热的值与公认值符合得很好。该文涉及到的实验方法和数据对冰的熔解热的测定具有重要参考价值。

How to measure the heat of fusion of ice in the non-adiabatic case was investigated.With difference to some traditional methods,the mixture of ice and water could be placed in the non-adiabatic environment in the measuring process.The effect on system from environment could be removed by controlling the heat absorbing or releasing between system and environment. The results show that the measured value was in good agreement with the reference value,through controlling the quality of three basic elements,i.e.,the mass of ice,the mass of water,and the temperature of water.The experimental methods and the data in this paper have important reference value for the measuring of the heat of fusion of ice.
