高能宇宙射线的时间变率
Time variability of high energy cosmic rays
摘要：
我们的模型涉及宇宙射线加速超新星遗迹已被用来预测宇宙射线强度在很长一段时间的统计基础上。如果（这是极有可能的）需要PeV宇宙射线引起的大范围空气簇射来引发陆地闪电，那么过去PeV强度的剧烈变化可能具有重要的生物效应。该模型已被用于估计PeV宇宙射线强度在地球上的变化方式在过去的数万年。
英文摘要：
Our model involving cosmic ray acceleration in supernova remnants has been used to predict cosmic ray intensities over long periods of time on a statistical basis. If, as is highly probable, extensive air showers caused by PeV cosmic rays are needed to initiate terrestrial lightning then past dramatic changes in PeV intensities may have had important biological effects. The model has been used to estimate the manner in which the PeV cosmic ray intensity at Earth has varied over the past tens of thousand years.
