摘要
观测能量大于１０１５ｅＶ的γ族事例，在乳胶室中往往形成晕，给进一步观测超高能核作用的特征带来许多不便．目前只能给出一些粗糙的量来描述晕事例．然而晕事例的内部还有精细的结构，能提供更多的信息．作者对超高能族事例尽可能作逐个簇射测量，并用测量晕的方法进行重复测量，进行比较．并就某些特例作了分析与讨论．
Gamma family events with visible energies higher than 1015eV usually form halos in the emulsion chambers,which bring up some problems for further investigating the characteristics of superhigh energy nuclear interactions. At present,only a few gross quantities are used for describing the halo events.On the other hand,there are some fine structures inside the halo, which can give us more information.We have measured all the showers one by one in the superhigh energy family events and compared the results with those obtained by the method of halo measurements.Analyses and discussions are made forsome special events.
