摘　　要：基于化学反应动力学的基本理论建立化学反应动力学模型,以深入研究利用低温等离子体技术降低柴油机尾气中NOx排放过程中的反应机理。文中以Matlab软件作为辅助工具求解微分方程组,进行计算机模拟,并在试验系统上进行验证,模拟结果与试验结果比较吻合,由此证明所建立的模型基本可靠,最后还得出一些有用的结论。The kinetic model of chemical reactions has been established based on the principle of chemical kinetics in the essay, in order to do some further research on the mechanism of reactions which occur during the process of purifying the NOx of diesel exhaust by the technology of non-thermal plasmas. The software of Matlab as to be an auxiliary tool has been used to evaluate a group of differential equations and the results are simulated on a computer, then to be validated on the experimental system, The agreement between the simulated results and experimental outcomes prove that the established model is credible, and get some useful conclusions at last.
