摘要
《物理化学》中燃烧焓的测定实验时间长,实验操作有一定的难度,实验一次性成功率低。经过大量的实验证明,改变燃烧皿的材质和装样的方法,并且改变夹层与量热容器的水温差值要求,缩短了实验时间,实验成功率达到99%以上。
Determination test on combustion enthalpy in Physical Chemistry need long time, the operation was difficult and the success of one trial was low. Through practice, experiment time was shortened and the success was reach 99% when material character of combustion dish, sampling mode and temperature difference betweens sandwich and calorimetry vessel were changed.
