摘　　要：利用模拟计算结果,对观测能量大于800TeV的γ族的原初粒子判别方法进行了讨论。根据γ族的横向分布判别原初粒子,对于质子是比较准确的。结合甘巴拉山乳胶室的大型γ族数据,用这一方法作了判别。The method of identification of primary cosmic ray particles of garnma families with vi- sible energies above 800 TeV has been investigated by using the results of Monte Carlo simula- tion. It has been found that, for proton primaries, the lateral distributions of certain parame- ters of gamma families may be taken as a reliable criterion. The experimental data of big ga- mma families obtained from Mt. Kanbala emulsion chamber experiment have been analyzed on the basis of this criterion.
