摘要
1989年9月29日发生了30多年来最大的地面宇宙线增强事件(即GLE事件)。本文描述这次世界范围内的大事件的主要特征,包括强度时间变化、能谱、各向异性以及地理位置上的分布特征,并简述了这次事件对地球环境产生的影响。
The ground level enhancement (GLE) from the solar proton flare of 29, Sept., 1989 is recorded by the world wide network of the neutron monitors and μ-meson telescopes. This GLE is the greatest event since the event on 23 Feb. 1956. The features of the world wide GLE including the intensity time profiles, the spectrum, the anisotropy and the geographical distribution etc. are studied in this paper. And the influences of the GLE on the earth's environment are described briefly in this paper.
