提出了一个估计溶质运移参数的确定性方法。通过Laplace空间的数学转换得到一个包含运移参数的线性时间函数。运用这个关系及两个时间观测浓度数据形成关于参数的非线性方程。求解参数的计算方法和数据误差分析也作了详细讨论。几个假设算例被用于检验参数估计模型 ,计算表明估计参数与算例设计的真参数有很好的一致性。

A method for estimating the parameters of solute transport is proposed. The linear time function is obtained from the Laplace transformation space. Based on this function and observation data the non linear equation for determining the parameters is established. The procedure of calculation and possible error are discussed. Examples are given for demonstration.
