摘　　要：大量现象和研究成果都表明核素以泥沙颗粒为载体进行迁移转化.本文运用环境科学、水力学、泥沙工程学基本原理,巧妙结合MATLAB数学工具和数学方法,创造性地提出了一维非稳态瞬时排放核素的迁移转化模型,并与连续排放核素的情况进行了对比.Many phenomena and findings have demonstrated that nuclide pollutants transform through the carrier of sediment. In this article, a one dimensional migration model of unsteady instantaneous nuclide emission in the sedi- ment of Zijiang river is derived by applying the theory of environmental science, hydraulics and the principle of sedi- ment engineering. The comparison between the models of unsteady instantaneous nuclide emission and continuous nu- clide emission is made in the last part.
