Abstract：
The traditional clustering method was improved.the family events were clustered in the scanning way,the criterion of multi-core event was redefined,through comparing the experimental results of multi-core events with simulation calculation,the nuclear interactions in the superhigh energy region were studied.Simultaneously,the method of using the energy fraction of main clusters to distinguish the big family event (∑E_γ≥500TeV) which is produced by primary proton was proposed by this work.
