摘要
把被定义区域的污染密度看成一张超曲面，再把该超曲面划分为形状相同相互连结的小单元，如三角形，在每个三角形顶点上设一个监测点，测该点的污染密度，以此来推导任一三角形的污染密度和整个区域的平均污染密度公式。把它应用到大气降尘上，就可求出大气降尘量。为大气降尘量和其他污染密度的计算，提供了一个新的方法。
First to look the pollution density of defined area as a supper curved surface,then todivide it into units joining each other which has the same shape,e. g. triangle,set up a monitorspot at every apex of the triangle,measure the pollution density of the spot and calculate the for-mula of pollution density at every triangle and formula of the average pollution density at wholearea with this. It is used to the atmospheric deposition, then the amount of deposition is workedout.This paper offer a new method for calculating the atrnospheric deposition or other pollutiondensity.
