Analysis of 1991 March 24 CME''''s structure using galactic cosmic rays'''' data
用银河宇宙线数据分析1991年3月24日CME的结构

In this paper,1991 March 24 CME's structure is analyzed by determining the moment of sudden change in galactic cosmic ray intensites using wavelet method based on the sudden change in galactic cosmic ray intensities when a CME just arrives at the magnetosphere. The results show that the thickness of the CME-driven shock is about 0.2228AU,while the space scale from the front side of the CME to the most intense magnetic structure is about 0.325AU.
