摘　　要：在复合气体添加剂作用的SNCR反应条件下,采用敏感性分析方法,对机理模型GAD98M99进行简化,选择126个反应替代461个反应的反应模型组成简化机理。在Chemkin4.1平台上,对简化机理与详细机理计算结果进行比较,表明得到的简化机理能在比较广的温度范围内（650~1 100℃）比较准确地预测气体添加剂影响下的SNCR反应过程。Sensitivity analysis has been used to reduce the kinetic model-GAD98M99 to simulate SNCR process considering the influence of multicomponent gas additives：CH4,CO,H2.The reduced kinetic model is made up of 126 reactions out of 461 reactions in the detailed model.By comparing the results with the two models through Chemkin 4.1,it is found that the reduced model can replace the detail model with little inaccuracy in the condition of temperature between 650~1 100℃.
