Based on adaptive multivariate nonlinear regression -BP neural network model for solar activity prediction, first establish the relationship between time and the number of sunspots model, and then based on the differential evolution algorithm model for solving, and then use the differential evolution algorithm model and BP neural network model for mixed model to solve, calculate the maximum for back generation, to achieve the next cycle prediction.	cache/fcis-27234.pdf	txt/fcis-27234.txt
