在MM5和RADM耦合的基础上，考虑了NH3的源排放，获得了NH3的时空分布、演变特征；在此基础上，讨论了气体向粒子的转化，结果表明：干气溶胶总量分布与大气中H2SO4、NH3的浓度分布有非常好的对应，富氨环境条件下，产生干气溶胶的多少是由H2SO4浓度决定的；气溶胶中的含水量与干气溶胶的浓度分布没有太多的联系，主要取决于大气中相对湿度的大小。

By evaluating MM5 (the Fifth Generation Penn State/NCAR Mesoscale Model), RADM (Regional Acid Deposition Model) and MARS (The Model for an Aerosol Reacting System), a coupled regional photochemical model is developed to study the transformation processes from gas to particle. With this coupled model, the characteristics of spatial and temporal distribution and variation of regional tropospheric photochemical precursors, products in the northern China are studied, such as SO2, NO2, O3, H2SO4, and HNO3. On the basis of this, the ammonia emission is considered and its spatial and temporal distribution and variation are obtained. The main conclusions are: the distribution of total dry particles is strongly correlated with the emission of SO2, NO2, and NH3; the total dry aerosol amount is mainly determined by H2SO4 concentration in ammonia-rich environment; the water amount in aerosol does not have good relationship with the distribution of dry aerosol, and it is mainly determined by the relative humidity.
