应用分子聚集理论改进的三次型状态方程(聚集硬球分子模型)

The cubic equation of state improved with molecular aggregation theory(Hard globular molecular model)

作者应用分子聚集理论对Van der Waals模型作了改进,从而导出考虑分子聚集的三次型状态方程,通过对30种物质(包括强极性和氢键缔合的物质)饱和汽和饱和液PYT数据的检验,表明该方程精度高,适用范围广。

The model, of Van der Waals has been improved by the author with the molecular aggregation theory, hence resulting in a cubic equation of state involving molecular aggregation. Through the examination of PVT data of saturated vapors and saturated liquids of thirty substances(inc'uding substances with strong polarity and hydrogen bond asscciation), it was shown that the equation has high precision and adaptability of broad range.
