  1. The second aspect : from qgp kinetic equations with collision integrals, by using the relaxation time approximation, we calculate the distribution functions to the second order correction. we obtain the distribution functions for quarks ( and anti - quarks ) and gluons under perturbation of the fluctuation of the color field. then in the high - temperature - low - density area, we discuss the characteristics of the distribution functions, and use t hem to get the net baryon density and the energy density

    第二,從有碰撞項的qgp動力論方程出發,忽略自旋,在色漲落擾動下,利用弛豫時間近似,得到夸克和膠子分佈函數的二級修正,通過數值分析重點討論了高溫低密情況下qgp中成分粒子分佈函數的特性,並且由分佈函數得到凈重子數密度和能量密度。
