计算了由夸克-胶子等离子体(QGP)颗粒表面强子化所产生的π介子和K介子的多粒子玻色-爱因斯坦关联. 对有限初始重子数密度的情况，K+介子的多粒子关联比π介子的多粒子关联弱，K-介子的平均多粒子关联强度随QGP颗粒数目Nd的增加而快速下降. 在零初始重子数密度情况下，K+和π介子的平均多粒子关联强度的差别随Nd的增加而变得明显.

The multiparticle Bose-Einstein correlations of pions and kaons produced by a surface hadronization of the quark-gluon plasma droplets are calculated. For finite initial baryon density, the multiparticle correlations of K+ are weaker than those of π, and the average multiparticle correlation intensities of K- decrease rapidly with the increase of the number of the droplets Nd. For zero initial baryon density the differences between the correlation intensities of K+ and π become obvious with Nd increase.
