采用程序升温手段，检测模拟机车排烟温度、排烟管气压降、烟气组成和烟气浓度的烟气催化净化效率。以Arrhenius方程、伯努利方程和克拉伯龙方程作为理论基础，根据反应速率和净化烟气效率随反应活性温度、烟气压力降以及烟气浓度之间的变化关系，推导出具有实用性的试验函数关系式。通过实验手段，校正修饰参数，导出反应速率与催化效率之间的函数关系式为：ηT=12πδe-（ ML-ln υ-Tμ）22δ2+C。

The catalytic efficiency for flue gas was detected by temperature programmed tichnique under the condition of simulate locomotive smoke temperature,air pressure drop,flue gas composition and con-centration. According to the reaction rate and the purification gas efficiency changed by reaction tempera-ture,the gas pressure drop and the flue gas concentration,the function with practicability relationship was deduced based on Arrhenius equation,Bernoulli equation and Clapyron equation as theoretical basis. Using experimental method to regulate modification parameters,the correlation function between reaction rate and catalytic efficiency was derived as follows:ηT= 1 2πδe-( ML-ln υ-Tμ)22δ2 +C
