摘要

应用线性代数理论，将等效热降法进行了扩展，使得其不但能够计算出蒸汽做功，而且能够计算抽汽系数、凝汽系数、再热份额、疏水量等其它参数值。这样，应用等效热降的法则，不但可以计算热力系统局部参数及系统变化时单位新蒸汽做功的变化，还可以计算这些局部参数变动所引起的上述其它参数变化量。最后给出了两个算例，其结果与常规热平衡法完全符合。

Abstract

By using the linear algebra the equivlent heat drop method has been extended to calculate not only the work done by the fresh steam but also the fractions of extracted steam and steam to condenser and to reheater

etc. This new method can be used to calculate the changes in the work done by fresh steam while the thermal system and any local parameters vary. Two examples are given to check the algorithm. It is found the results obtained by this method quite agree with that obtained by normal energy conservation method.
