【摘要】 在全面收集整理和评价目前文献报导的蒸气压估算方法的基础上，建立了一个功能较全、易于推广应用的纯物质饱和蒸气压软件包。纯物质的饱和蒸气压是重要的热力学性质之一，也是化工过程设计与控制必不可少的重要基础物性数据。因此准确估算纯物质的饱和蒸气压的方法和软件系统有十分重要的理论和实际意义更多还原

【Abstract】 n the basis of comprehensively collecting, systermatizing and evaluating estimationmethods for saturated vapor pressure reportedon current literatures, a computer packagewhich has more functions and is easy to bespread out for estimating saturated vaporpressures of pure substances has been established. The saturated vapor pressure of puresubstance is one of the important thermodynamic properties and is an essential basic datum for chemical engineering process designand control. Therefore, the method and package system for accurately estimating saturatedvapor pressures of pure substances are of veryimportant theoretical and practical significance.更多还原
