摘　　要：最近，一个困扰人们达十几年之久的γ射线源Geminga被证认为X、γ射线脉冲星，其光学对应体也被确定为一颗光谱偏蓝的25等星。对Geminga脉冲星的确证说明存在着一类没有射电辐射的脉冲单星。与以往的评述文章不同，作者从观测和数据分析角度介绍了人们对Geminga的认识过程以及有关的高能天体物理中时间分析的基本方法。Recently, a gamma-ray source Geminga, which has been mysterious for more than ten years, was identified to be an X and Gamma-ray pulsar. It's optical counterpart was also argued to be a star of lnagnitude 25 with blue spectrum. The ekistence of Geminga indicates that. there exists a kind of single pulsars which have no radio emission. This paper introduces the improvement process of the knowledge about Geminga and the related fundamental method of time analysis in Higll Energy Astrophysics.
