Abstract: This paper describes the study of optimal discrimination in detail among rival models for the reaction of synthesis of ammonia on "A" catalysts. For this purpose the sequential procedure has been applied, the parameters in candidate models have been preliminarily estimated, and rival models have been screened with proposed criteria. The discrimination was achieved. One of the models was found superior to the others and was finally retained. This paper also deals with the selection of algorithms for least-squares fitting, the details of technical matters in discrimination procedure and the criteria for identification of models.

摘要： 本文详细讨论了用序贯法对“A”系催化剂上氨合成反应的速率模型最佳判别的过程;对不同速率模型中的参数进行初估,按设定的准则作序贯判别,最后选出优惠的模型方程。 文中还讨论了最小二乘法的选择;判别过程的具体技术问题及模型的判别准则。
