摘　　要：在沈阳城区按功能区特点设立１２个空气采样点采集空气。经仪器测出各功能区空气中的菌落数，并用奥美良斯基公式计算出各处大气中细菌粒子的浓度分布。结果表明，这些细菌粒子的浓度分布也同样适用于麦克斯韦速率分布律，即大气中细菌粒子的浓度越大，其比率也越大。Twelve sample stations of air-collection were set up according to property of function districts inShenyang urbon area。Air was collected on the pan by natural sinking. Having been dealt with,the strains of bac-teria particle were tested by instruments in each function district.The distribution of dense of the bacteria parti-cles in the atmosphere has been obtained by formula of microbiology and it does fit in with Maxwell DistributionIaw,that is,the denser the distribution of the bacteria particles in the atmosphere is,the greater the rate is.
