摘要
对流─弥散方程和渗流基本微分方程中的源汇项，分别是决定含水层中任一内点上水质量和溶质质量时变率的重要因素之一。而关于源汇项不适当的乃至是错误的表述，在文献中却不乏其见，其影响之大是显而易见的．本文深入分析了某些表述的不当或错误之处，给出了正确的处理与表述方法。
The terms of source and convergence in the covection dispersion equation and the basic differential equation of seep-now are partly main factors, which decide a time-change ratio of the water and solute qualites in an any point of aquifers.Some unsuitable and even wrong expressions on the terms of source and convergence are nothing mew in some literatures.It is quite obvious that their influence is very tremendous. This paper deeply analyses some unsuitable or wrong points and gives a correct treatment and expression way.
