| 摘 要： | 从平流扩散方程出发，通过对方程中扩散系数的选择及时间微分项的求解，建立了一个适合中性大气条件的浓度场预测模式。该模式模拟计算值与实测值比较，浓度场最大相对误差为－２８．０％，在１．５倍偏差范围内。

| Abstract: | Starting from the advective diffusion equation, by choicing the diffusion coefficient and solving the differential term with respect to time for the equation, a predication model for the concentration field suitable for the condition of neutral atmosphere is set up. The simulated values obtaining from this model are compared with practical monitoring values, the maximum relative error of the concentration field is-28. 0%, and in the range of 1. 5 times of deviation. |
