| 摘 要： | 提出了粒子群关联概念，并以此建立了一种检测集合流的新方法，采用新方法对２．１ＡＧｅＶＮｅ＋ＮａＦ碰撞的Ｂｅｖａｌａｃ流光室４π实验事件粒子群的关联进行了研究．通过与蒙特卡罗结果进行比较，推测该实验事件集合流的集体性约在７５％－９５％之间。

| Abstract: | A concept of particle-group correlations is proposed in this paper. In according with the new concept, a new method of collective Dow measurement is constructed. Using the new method, the particle-group correlations arising from collective flow are studied with 4. data lbr 2. 1A GeV Ne NaF collisions at the Bevalac streamer chamber. Comparing with the Monte Garlo results, the collectivity of the particles in the final state of this collision is inferred in the range from 75% to 95%. |
