摘要
化学反应过程中热量衡算通常情况下主要就是焓差的计算,焓是一种状态函数,其绝对值无法求取,比焓和焓差的计算成为热量衡算的主要任务。比焓和焓差的计算关键是计算基准的确定,同时也离不开热容值的正确获取。
The calculation of heat balance can mainly be regarded as enthalpy minus enthalpy in chemical reaction course. Enthalpy is a kind of state function. Its absolute value can not be got. The primary mission of heat balance is calculation of specific enthalpy and enthalpy difference. The key to calculate the specific enthalpy and enthalpy difference is to make sure of the benchmark as well as the value of heat capacity value.
