大气污染物等浓度曲线画法初探

On the drawing method of atmospheric pollutants concentration contour-line

介绍一种环境影响评价中大气污染物等浓度曲线的画法,可用于绘制任意接近的等浓度曲线而不会相交或相切,运算量较小且与图形大小无关。

A drawing method of atmospheric pollutants concentration contour-line,which is required as a result of environmental impact assessment,was described. No intersection or tangent will come across with this method. Furthermore,this method is independent on the size of chart and consumes fewer computing time.
