摘　　要：对甘巴拉山铁乳胶室所观测到的部分族事例与 Ｃ Ｏ Ｓ Ｍ Ｏ Ｓ 程序产生的模拟族事例进行可识别高能核心的共线性的分析，得到与 Ｐａ ｍｉｒ 组基本一致的结果．The alignment of energetically distinguished cores both in a part of family events observed with Kanbala iron emulsion chambers and the simulated family events given by COSMOS code is analyzed.The results obtained in this work are basically in agreement with those of Pamir Collaboration.Simultaneously,the criteria of identifying γ rays and hadrons are also discussed.
