| 摘 要： | 根据聚合级次定律提出一种相对论重离子碰撞中粒子鉴别的新方法。采用该法分析了Ｂｅｖａｌａｃ流光室１．２Ａ ＧｅＶＡｒ＋ＢａＩ２和２．１ＡＧｅＶ Ｎｅ＋ＮａＦ４π实验事件中ｚ≤２的粒子及碎片的产生几率。发现了粒子鉴别前后两种实验事件快度分布的变化。

| Abstract: | On the basis of the coalescence power law,a new method of particles identification is proposed. By using new method,the production p] obability of particles andfragments of z<2 for 4rs experiments events of l.2 A GeV,Ar + Bal, and 2.1 AGeV Ne+NaF collisions in the Bevalac streamer chamber is anillysed. The change of rapidity distribution after particles identification is found. |
