Abstract

By mean of monitoring SO₂ and NO_x, we put forward a new conception about air ground pollution belt, and get two-dimensional finite difference equation of air pollution. Meanwhile dispersion coefficient and wind speed are considered as gray parameters. One gray numerical quality model of air pollution is built according to gray theory and applies to the air pollution diffusing system of Handan city, and simulates SO₂ and NO_x during heating times and unheating times. The result shows the gray numerical model is suitable for application.
