Shock tube is a very important tool in the study of high temperature chemical kinetics, but there exist some drawbacks in its application for accurate measurement of chemical kinetic parameters.This paper is concerned with the study of using non-tailor chemical shock tube for overcoming the shortage and getting the good chemical kinetic results.The kinetic parameters for two reactions, t-butyl chloride decomposition and ethylene oxide isomerization were studied under non-tailor condition. Experimental results showed that good results could be obtained by using the comparative method instead of using the calculation method to get the temperature of system by shock velocity.
