【Abstract】 Based on predecessors’work, and the plant data of total conversion rate and number averaged molecular mass, the Cauchy distribution of micro cores is proposed in terms of the principle of probability and statistics. The macro kinetic model with expressions of the total conversion rate and number average molecule mass is derived from the macro mixed method. Additionally, the neural network sub model and the regression sub model are used in the model for building up the correlation functions of intermediate parameters k 1, k 2, and k 3 with the operation conditions. It is verified by the simulation and practical running results that the model can present practical process properties.更多还原
