摘要
利用１９９０年６月至１９９３年１０月间采集的数据，西藏空气簇射阵列（海拔高度４３００ｍ）以５．７、７．１的显著性观测到了１０ＴｅＶ宇宙线的太阳阴影和月亮阴影；研究发现，行星际磁场效应使太阳阴影偏向西０．６２°，南０．２２°：仔细研究了太阳阴影与太阳活动及其不对称性的关联，对太阳阴影位置的偏转发其变化行为给出了新的定性解释。
Using the data obtained in the period of June 1990-October 1993,the shadowsof the Sun and the Moon have been detected at 5.7 and 7.1 levels respectively inthe 10TeV cosmic ray flux by the Tibet air shower array at an altitude of 4300mabove sea level. The shadow of the Sun is found to be deflected away from the Sunby 0.62°to the west and 0.22 to the south by the interplanetary magnetic field.The correlations between the shadow of the Sun and Solar activity and its asymmetryare studied in Detail. A new qualitative explanation to the shift and yearly variation ofthe Sun's shadow is presented.
