摘　　要：运用空气质量模式的基本理论,研究汽车尾气排放的扩散规律。选用多种典型空气质量模式,对汽车污染进行计算机模拟。在每一模式下,可对大气稳定度、混合层高度、扩散参数等进行选择计算;并能进行瞬时浓度及长期浓度的预测。设计的程序适用于各种气象条件、各种道路条件、各种车型。Laws of automobiles exhaust gas emission are studied on the basis of the fundamental theory of theair quality mode. Automobile pollution is simulated on computer with various typical air quality modes. With eachmode, the atmospheres stability, the mixed layers height and the emission parameter can be calculated and theinstantaneous concentration, the long-term concentration can be predicated. The program designed properlyapplies to various meteorological and road conditions and various type of vehicles.
