英文摘要：

A software platform for the optimization of frequency response characteristic function used for the characterization of catalysts has been developed based on LabVIEW. The optimization algorithm of simplex algorithm and Powell method were introduced, as well as fundamental principles refer to catalyst models and objective functions. The flow chart of program platform was presented. Design procedures, the graphic programs and some other techniques for main program VI and model configuration, simplex method, theory model, etc. were＇also described.
