【摘要】 用特征函数法（Ｋａｒｈｕｎｅｎ－Ｌｏｅｖｅ方法）求解分布参数系统中的偏微分方程，状态变量用包含特征函数的双正交基函数展开，可以降低方程组维数。比较动态实验获得的特征函数与模型计算值，作为竞争模型鉴别依据，并以丁烯氧化脱氢作为研究对象，说明该方法在动态动力学模型参数估计与模型鉴别上的有效性。更多还原

【Abstract】 Partial differential equdtions used to describe distributed parameter systems are solved by the eigenfunction,by which state varibles are expanded with double orthonomal set for dimen- sion reduction. Comparision between calculated and experimentally determined eigenfunction distributions can be applied for model discrimination.The present method is proved to be valid for studying parameter estimation and model dis-crimination of the oxidative dehydrogenation of butene as an example.更多还原
