过热水蒸汽的热焓是蒸汽动力装置热力计算中经常用到的一个状态参数。一般是在已知蒸汽温度、压力的条件下,由水蒸汽热力学性质表查取,对表上不能直接查得的数值,则采用线性内插法计算。这样求取焓值,既查表又计算,比较复杂。现在由于电子计算器应用普 The enthalpy of superheated steam is a commonly used state parameter in the thermal calculation of steam power plants. Generally known steam temperature and pressure conditions, the steam thermodynamic properties of the table access to the table can not directly check the value, the use of linear interpolation method. This enthalpy, not only look up the table and calculation, more complicated. Now due to the application of electronic calc universal
