Abstract: Curve fitting method of BP neural network was introduced and applied in the model of the dispersion of calcite crystals by MATLAB tools. The results show that BP algorithm has high forecasting capacity and good generalization capacity in three areas: the map of curve fitting, the deviation curve and the error norm. BP neural network can automatically identify mathematical model, which has higher precision, and its principle is relatively simple. So it is a very good tool for complex input-output system.
