The records of cosmogenic nuclides in Dome Fuji ice core, covering 720 kyr, wereanalyzed by means of Accelerator Mass Spectrometry. By analyzing several prominentgeomagnetic events, Laschamp, Blake, Iceland Basin, in detail, the records ofcosmogenic nuclides, especially Beryllium-10, were found to be excellent indicator ofthe variation of cosmic ray intensity.

本文用加速器质谱法分析了72万年以来富士冰穹冰芯中宇宙成因核素记录。通过对冰岛盆地Laschamp、Blake等几个重要地磁事件的详细分析，发现宇宙成因核素，特别是B_2O_3 -10的记录是宇宙线强度变化的良好指示。
