熵方程 meaning in English

entropy equation

In order to accurately calculate the available energy dissipation resulted from the steam flowing through a restrictive device , a new view point for measuring energy in steam piping network system has been put forward , i . e . a model for computing the available energy dissipation has been obtained through entropy equation in occurrence process of the resistance , which is deduced from steam condition equation of iapws - if97
为了准确计算蒸汽流经阻力件产生的可用能损耗，提出了蒸汽管网系统能量计量的新观点，即通过iapws - if97的蒸汽状态方程，推导出阻力发生过程的熵方程，得到可用能损失计算模型。
