摘要
给出了具有单裂隙的双重介质中，裂隙一端有分时注入源情形下的迁移模型的解析解及一些简化条件下的解析解；并利用解析解研究了核素在双重介质中的迁移问题。
In this paper, a analytic solution of modelling radionuclide migration infractured porous media with a sectioned point source in fracture has been derived andsolutions under the problem has been simplifed and given. The solution has been used tocalculate concentration of radionuclide in fractured porous media.
