本文分析了太阳质子事件的发生频率与太阳活动水平、质子事件大小的关系和峰值通量的分布特征,参考尼米克(1997)的工作,引入蒙特·卡洛方法建立了太阳质子事件统计模式,可以计算以太阳黑子数(SNN)表征的不同的太阳活动水平下高能质子及其他重粒子的能谱和峰值通量特征等参数,计算结果与实测数据接近。 This paper analyzes the relationship between the frequency of solar proton events and the solar activity level, the size of proton events and the distribution of peak flux. Referring to the work of Nimik (1997), the Monte Carlo method is introduced to establish the statistical model of solar proton events , The energy spectrum and peak flux characteristics of high energy protons and other heavy particles under different solar activity levels, which are characterized by SNN, can be calculated. The calculated results are close to the measured data.
