Secondly, the enthalpyof elementary substance under standard state is defined as the criterion of component enthalpy, thus reaction heat is no longer needed in energy balance.
其次，热量衡算时，将标准状态下单质的焓定义为所有组分的基准焓，不再需要反应热数据。

The former includes the calculation ofreaction free enthalpy, equilibrium constants, maximum output, gaseous phase partial pressure and theoretical decomposition voltage of molten salt electrolysis.
