摘　　要：根据喷注判定的圆锥法来判断喷注，重新分析了ＵＡ１－１９８５年的６３０ＧｅＶ非单衍ｐｐ碰撞实验数据。分析发现对事件样本，单事件平均横动量ｐ与多重数ｎ是正关联的，而对喷注事件子样本则是负关联的；According to jet definition-cone algorithm to identify jets, we reanalyse UA1 minimum-bias non-single diffractive pp data at =630GeV, The correlations between pt and multiplicity for the event sample and subsamples are studied in detail. We found that they are positively correlated for the event sample, while negatively correlated for the jet event subsample. The correlations and decorrelations between mini-jets are also studied. We further analyse the possibility of large rapidity gap existence between the two minijets, and find that there are no particles between two minijets in some events, but the statistics are not enough.
