摘　　要：研究了费米子动力学效应对两胶子、三胶子凝聚的贡献,研究结果表明:随温度升高,胶子凝聚值比未计及费米子动力学效应衰减得更快;并且随着夸克味数的增加,加快衰减.当味数N_f=3时,胶子凝聚消失的温度为T_0≈200MeV。On the basis of the references [1-3], the effect of the fermionic dynamics to the two-gluon condensates and the three-gluon ones are investigated. It is found that due to the effect of the fermionic dynamics the values of the gluon condensates decrease last with the temperature, and their decreasing rate increases when the fermion flavor number increases. The values of the gluon condensates are found to be vanish at T0≈200 MeV for the flavor number Nf= 3.
