利用羊八井ASγ阵列实验数据分析宇宙线的较长周期变化.收集整理Tibet ASγ阵列1994～2003年间记录的宇宙线触发率数据和气象数据,发现这段时间的宇宙线触发率存在明显的年周期变化,气压、室内温度、室外温度与宇宙线触发率有着相似的年变化,存在较强关联;对宇宙线触发率进行多元气象参量修正,修正后的宇宙线触发率不再有明显的年变化;利用小波分析和数学统计方法分析气象修正后的宇宙线触发率,没有发现确定的几日周期.统计结果显示：宇宙线周期变化中4日周期和6日周期较多,其次是5日7、日和8日周期.

With the Yangbajing AS＇y array, the longer periodic variation is studied. First, cosmic ray flux re- corded and meteorological parameters between 1994 - 2003 are collected and tided. The annual variation of the cosmic ray flux data is obvious. The annual variation of each meteorological parameter likes cosmic ray flux. There is obvious correlation existing between cosmic ray and each meteorological parameter. After the meteorological effect of cosmic ray being corrected by using multianalysis, there is no annual variation of cos- mic ray. Then the cosmic ray flux after corrected is analyzed with wavelet analysis and statistics. It is found that there is no uniform variation of several diurnal. Statistical result of data shows that there are more 4 diur- nal and 6 diurnal variations of the cosmic ray, the next are 5 diurnal, 7 diurnal and 8 diurnal.
