英文摘要：

The BP neural network algorithm used in approximation of function has two shortcomings which are slow convergence rate and easily falling into the local. In order to solve the problems, a new method is proposed in this paper and is complicated on a typical complex system-the synthetic ammonia decarbornization industrial process. The main issue of the proposed approach is on modelling and optimization of the RBF （Radial Basis Function） neural network. The learning capability of RBF neural network on processing nonlinear system is used, and the modelling and optimization of RBF neural network is present. Furthermore, some simulation studies with calcinations section have been done. The simulation result shows the superiority of the RBF neural network.
