| 摘 要： | 从质量守恒原理出发推导出开放系统两个新的质量平衡方程：Ｃ＾ｏｉ－Ｃ＾Ａｉ－△Ｃｉ,（Ｃ＾Ｏｉ－Ｃ＾Ａｉ）／Ｃ＾Ｏｉ＝μ（Ｃ＾Ａｉ／Ｃ＾Ｏｉ）－μｉ。该方程不公在图示和计算方面均优于Ｇｒａｎｔ方程,而且还同时将Ｂｒｉｍｈａｌｌ和Ｄｉｅｔｒｉｃｈ质量平衡方程作为一个特例而包容它。

| Abstract: | On the basis of mass balance two new mass-balance equations for open systems have been attained as follows:which have the advantages of diagramatization and calculation over Grant'sequation, and include equations of Brimhall and Dietrich as a special .case. "Isocon" defined by Grant is reexamined and thought to be inappropriate. and can be replaced by characteristic mass-to-mass ratio line: O'Hara's formula for the calculation of mass changes is incorrect according to the relationship among mass, volume, density and porosity changes in the system. Three new diagrams are established to distinguish immobile elements in open systems in order to resolve problems involved in other previous diagrams. |
