| 摘 要： | Wigner- Dyson型的随机矩阵理论作为一种可能的统计分析方法用来分析高能重离子碰撞中所产生的粒子谱的某些无规性 ,此统计分析方法被用来初步分析了EMU0 1的实验结果 ,通过分析可以看出在 CERN/SPS和 BNL/AGS能区粒子主要是随机产生的. In high energy heavy ion collisions, a possible measure for a certain irregularity of the spectra of produced particles is proposed by using the Wigner-Dyson statistical analysis method. The preliminary results from EMU01 experiments are given by using this statistical analysis method. The analysis shows that the dominant effect is random emission in available high energy nucleus-nucleus collisions at CERN/SPS and BNL/AGS regions.
