英文摘要：

The object of study is the selectivity catalyzes deoxidation （SCR） flue gas denitration system. Based on the study of its reaction mechanism, the SCR dynamics model was then obtained, which was used to build the simulation platform in Matlab. The platform could simulate the basic process of SCR flue gas denitration, and then the data was comprehensively analyzed. Therefore, with the arranged data, soft-sensor methods were used to build the corresponding model, which was applied to realize the control of the SCR denitration process.
