液体仓库污染评估模型

Mathematical Models for the Assessment of the Ground Pollution of a Liquid Storage

建立了两个数学模型 ,利用仓库周围样品所测得的数据来评价液体仓库对土壤的污染情况 .两个模型抛开传统的复杂三维微分方程 ,分别从水平切面和竖直剖面入手 ,建立二维微分方程 ,并解出可以用代数方法确定参数的解析解 ,同时 。

In order to assess the ground pollution of a liquid storage, this paper establishes two mathematical models according to the principle of diffusion. The models are established in terms of horizontaled diffusion and vertical diffusion, discarding the traditional and complex three-dimension differential equation. Their analytical solutions whose parameters can be ascertained by solving algebra equations through proper layout of sample spots are discussed in the paper.The paper also addresses the method of sampling as well as the type and number of measurements meehool.
