Abstract：
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 N_d. For zero initial baryon density the differences between the correlation intensities of K⁺ and π become obvious with N_d increase.

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 N_d. For zero initial baryon density the differences between the correlation intensities of K⁺ and π become obvious with N_d increase.
