摘要：

本文以水相和泥沙相核素的物理迁移为基础,分析深海采矿船附近海底重金属的迁移扩散､吸附解析和悬移沉降等作用,结合水力学､泥沙动力学等方程,建立了重金属迁移转化的整体模型和分相模型,并利用差分算法对模型进行求解,最后结合实验测定和实测资料给出的模型相关参数,运用MATLAB软件对重金属的迁移进行图像模拟,直观地反映重金属浓度的变化过程.

Abstract: Based on the physical migration of the water phase and the siliceous nuclide,this paper analyzes the migration and diffusion,adsorption and suspension of the heavy metals near the deep sea mining vessel sedimentation. A global model and some phase separation models of heavy metal migration and transformation are established by making use of the equations of hydraulics and sediment dynamics.The models are solved by differential algorithms.Given the parameters in the models by experiments or measurements,the migration of heavy metals is then simulated by the MATLAB software with intuitive demonstration.
