| 摘 要： | 太阳耀斑爆发与多种因素存在着非线性的关系,其中规律难以把握.选择时间变化长短,工作频率,路径大圆距离,VLF传播相位变化偏移量4个与太阳耀斑级别预测密切相关的重要因素,构建了BP神经网络模型;然后利用Matlab工具箱对网络模型进行系统仿真与多次训练,使网络的预测输出不断逼近期望输出,实现对太阳耀斑级别的预测,通过结果误差分析,表明这种方法具有有效性与可行性.

| Abstract: | there is nonlinear relationship of various factors with solar flare,in which the law is difficult to grasp.We select the length of time-varying,operating frequency,the path of the great circle distance,the VLF propagation phase change offset four forecast solar flares level Closely related to important factors to construct a BP neural network model.Then use the Matlab toolbox to network model for system simulation and training for many times.The predictive output of network continues to approximate the desired out put,the solar flares level forecast by the results of error analysis showed that this method has validity and feasibility. |
