| 摘 要： | 将ＤＳＦＤ优化方法引入状态方程的拟合中，在Ｌｙｄｅｒｓｅｎ修正的两参数普遍 化数据表的基础上，关联出Ｚｃ为０．２７流体的通用状态方程和饱和蒸气压方程，并由此 导出了其他热力性质的解析表达式。在０．５≤Ｔｒ≤１５及０．０１≤Ｐｒ≤３０的广泛范围内， 在偏差函数的计算精度及连续性方面，均比Ｌｙｄｅｒｓｅｎ数据表有较大改进，并且编制了计 算程序．编绘了热力性质两参数统一通用计算图。可方便地同时确定密度、各种偏差函 数、焓差、熵差、内能差、焓 、内能 及其组成部分热 及机械同等热力参数。

| Abstract: | The DSFD optimization method is first introduced into the data- fit-ting for the equation of state (EOS), which makes the generalized EOS and vapor pressure equation for fluids with Zc = 0.27 based on the two-parameter relations proposed by Lyderscn. Furthermore, the expressions for other thermodynamic properties are also derived there from. The average relative deviation of Z is 0.9% when Pr is between 0.01 and 30.0 and Tr is between 0.5 and 15.0. For engineering purposes, we present a new two--parameter integrated generalized chart drawn by computer for determining the thermodynamic properties of fluids with Zo = 0. 27. |
