Abstract: In this paper the analytical solution for one dimensional convection flow with alkali loss is obtained by using the method of Laplace transform. Under the assumption of fixed streamline, we can generalize the solution for two dimensional convection flow. Therefore the distribution of alkaline concentration and alkali loss may be analyzed and calculated.

摘要： 本文用Laplace变换的方法求得了碱水渗流时,一维对流模型的精确解。在流线不变的假定下,可以将结果推广到二维渗流的情形。据此,可以计算、分析注采井组碱水浓度分布和碱耗量。
