摘要
根据重金属的传播特征,建立了关于确定表层土壤重金属污染源的偏微分方程模型.运用数值积分以及参数估计,得出其单位体积内重金属污染物的质量.同时,利用MATLAB软件拟合二元二次方程对其进行数值求解,从而较方便且准确地确定出重金属污染源的具体位置.
According to the propagation characteristics of heavy metals, the partial differential equation is constructed to determine the heavy metal in the surface soil pollution source model. Using the numerical integration and parameter estimation, the unit volume of heavy metal pollutants in the quality is obtained. At the same time, by use of MATLAB software to fit two variables quadratic equations, the numerical solution is derived, which is more convenient and accurate for the determination of the heavy metal pollution source location.
