| 摘 要： | 在相同初和排放条件下，对四种应用较广的光化学烟雾反应机理（GB4－99RADM2,RACM,SAPPRC99）进行了6组方案的比较，比较物种包括：（1）OHHO2自由基，（2）H2O2，HNOE，PAN，甲醛和有机硝酸酯光学产物，（3）甲苯和SO2，（4）NOy,NOa，由于各机理对VOCs，自由基及含氮化合物处理的不同，导致了模拟结果存在较大差异，我们用模式模拟这些物种时，应特别注意要理不同而带来的模拟结果差异。

| Abstract: | A comparison of four atmospheric photochemical mechanisms (e.g. CB4-99, RACM, RADM2, SAPRC99) was conducted by using the same initial values and emission data. Eight species (including: (1) OH and HO2 radicals, (2) H2O2, HNO3, PAN, formaldehyde and or-ganic nitrate, (3) toluene and SO2, (4) NOy NOa and NOz) were studied. Due to the different methods of lumping VOCs and treating radicals among the four mechanisms, significant differences of the prediction were found. Therefore, for selecting mechanisms in simulating of these species it should be paid more attention to the difference of photochemical mechanisms. |
