摘　　要：研究了甘巴拉山厚铅乳胶室族事例中高能簇射的特征．给出了族中观测能量Ｅｒ（Ｅｈ）≥１０ＴｅＶ的高能ｒ簇射、强子簇射及退级联后的单个簇射与簇射团的能谱和能量加权横向扩展的分布．将实验结果同ＨＤＳＱＩ模型模拟的结果进行比较，结果表明，ＨＤＳＱＩ模型基本上能说明族中高能簇射的能谱及横向特征．The characteristics of high energy showers in family events observed by thick-type Ph emulsion chambers at Mt. Kanbala are studied. The energy spectra and the energy-weighted lateral spread distributions of the gamma and hadronic showers in family events and the single gamma and cluster showers in rejuvenated families with visible energy Era10TeV are presented. The comgiarisons of experimental results with Monte carlo simulation and some discussions are given. It is shown that the measurements are consistent with the predictions o f the HDSQI model.
