摘要
对新的马丁-侯状态方程(简称M-H-th方程)特征常数求解算法进行了优化改进,使特征常数不随蒸发点的选取而改变,把M-H-th方程优化改进的特征常数算法应用于水蒸气,得到了基于M-H-th的水蒸气状态方程。新的水蒸气状态方程只有10个特征常数,精度高于原水蒸气马-侯状态方程,可以应用新的水蒸气状态方程计算水蒸气焓、熵,适用于水蒸气(汽轮机)建模。
The new Martin - Hou equation of state （ M - H - th equation） characteristic constant so- lution method was optimized, which makes the characteristic constant do not change with the selection of the evaporation point. The characteristic constants of M - H - th equation optimization were applied to water vapor, and the water vapor equation of M - H - th was obtained. New water vapor state equa- tion only has 10 characteristic constants, the accuracy of state equation is higher than the original water vapor Martin - Hou state equation, can be applied to new vapor state equation calculating the steam enthalpy, entropy, is applicable to water vapour （steam turbine） modeling.
