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.
