在概化的平面区域内，采用上述方法模拟了二维初始浓度高斯分布和水流激波在旋转速度场及均匀速度场上的对流输移问题，结果表明方法在优化幅值衰减和数值扰动以及计算效率方面具有相当的发展潜力和应用前景

The technique of boundary-fitted coordinate system is used to overcome the difficulties resulting from the complicated shapes of natural river boundaries;the method of alternating direction implicit finite difference scheme is used to solve the partial differential equations in the transformed plane;and the technique of moving boundary is used to deal with the river bed exposed to water surface.

用适体坐标技术克服天然河道复杂的几何边界给有限差分法所带来的困难；用交替方向隐式有限差分格式求解变换平面上的偏微分方程；用动边界技术处理河床的淹露。

Calculated the lower limit of abnormal after the plane through the delineation of the contour map of the occurrence and analysis of abnormal findings were as follows: work area on the lithology in terms of more or less divided into two parts, East and West, the western area for the low-resistivity, lithology is metamorphic carbonaceous sandstone or slate, for the emperor in eastern areas, lithology for granite and granite porphyry, quartz vein occurrence in eastern and more, these quartz veins is into the eastern part of the resistivity of the form of alternating high and low.

计算了异常下限值后，通过圈定了平面等值线图上的矿点异常和其它分析得到结论如下：工区就岩性而言大致划分为东西两部分，西部为低阻区，岩性为变质砂岩或炭质板岩，东部为高祖区，岩性为花岗岩及花岗斑岩，东部多赋存石英脉，这些石英脉是的东部电阻率成高低交替的形式。
