摘　　要：运用PT状态方程计算纯物质饱和蒸汽压的性质,由于所联解的方程为非线性,计算流程涉及多次迭代求根等形式,人工计算是非常复杂的,甚至无法完成。而利用Excel超强的数据处理功能,通过简单的设计,可以比较容易解决饱和蒸气压和其相关的热力学性质的计算。PT calculated using the equation of state the nature of the saturated vapor pressure of the pure substance,since the combined solution of the equation is nonlinear calculation process involves multiple iterations Root and other forms of manual calculation is very complicated,if not impossible to complete. The use of Excel's powerful data processing capabilities,a simple design,can be relatively easy to solve,and its saturated vapor pressure related to the calculation of thermodynamic properties.
