本文在玻色-爱因斯坦凝聚的演化π介子气体（EPG）模型中计算了全同π介子的三粒子和四粒子关联。分析了EPG模型在不同动量间隔下的多π关联函数，并与Pb-Pb碰撞的实验数据进行了比较
We calculate the three-and four-particle correlations of identical pions in an evolving pion gas (EPG) model with Bose–Einstein condensation. The multi-pion correlation functions in the EPG model are analyzed in different momentum intervals and compared with the experimental data for Pb–Pb collisions at
