基于同伦方法反演非饱和土中镉离子传输参数

PARAMETER DETERMINATION OF Cd++ TRANSPORT THROUGH UNSATURATED SOILS BASED ON HOMOTOPY METHODS

摘要: 依据实验室土柱实验结果，引入同伦方法对镉离子在不同非饱和土样中的传输参数进行了反演计算，得到了相应的反演结果.

Abstract: Homotopy methods were used for computing modelparameters of Cd + + ion transport through unsaturated soils.Numerical results demonstrate the feature of stability and globalconvergence of the homotopy methods. Calculated BTCs agree well withexperimental BTCs.%Computational results could be referenced by practical problems.
