概论 在探讨外因对地震的调制和触发作用时,以往人们曾作了许多研究工作。如寻找固体潮、气象条件、磁暴等各种外因与地震发生的相关性,讨论其中的物理机制等。本文则试图对宇宙线这一外因的强度变化与大地震之间的关系作一探讨。 Introduction Many studies have been conducted in the past when discussing the modulation and triggering of external causes of earthquakes. Such as looking for tide, meteorological conditions, magnetic storms and other external factors and the occurrence of the earthquake, the discussion of the physical mechanism. This article attempts to discuss the relationship between the cosmic ray intensity change and the major earthquake.
