| 摘 要： | 利用三维欧拉型污染物输送模式，气相过程分别采用查表法处理和直接耦合区域性光化学模式（ROS），对1992年硫氧化物输送、沉降量与实测值进行了模拟比较。结果表明，查表法可以节省大量的计算时间，所用时间约为直接耦合化学模式的1／7，查表法处理气相过程能够较好地反映SO2和SO4^2-浓度分布与沉降状况，与直接耦合化学模式具有同样的精度和较好的可信度。 |

| Abstract: | Using a 3\|D Eulerian transport model with the gas\|phase chemical process adopted a look\|up table method and directly coupling regional photochemical model (ROS) method, the transport and deposition amount of sulfur oxides in 1992 were simulated and compared with the observed data. The results show that the coupling method takes as approximately seven times computation time as the look\|up table method whereas the look\|up table method has a general agreement with the observed values in accuracy as the coupling one does. It is suggested that the look\|up table method succeeds in dealing with gas\|phase chemical process for SO x reactions and is very promising in simulation of long\|range transport of SO x pollutants and regional\|scale forecast of air quality. |
| Keywords: | sulfur oxides look\|up table method Eulerian transport model |
