摘要
本文以 P—R 方程为基础,推出了预测维里系数的新的关系式.预测结果表明,新关系式应用简便,计算精度较高,在一般工程计算中具有一定的实用价值。
Based on the P—R equation,a new relative equation about Virial coefficient is forecast in this article,then it is tested with the reference data of fluidal P-V-T properties.As a result, this relative equation is not only simple to use,but also more accurate to calculate,so it has more practical value in the ordinary engineering calculation.
