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(fā)，忽略自旋，在色漲落擾動下，利用弛豫時間近似，得到夸克和膠子分布函數(shù)的二級修正，通過數(shù)值分析重點討論了高溫低密情況下qgp中成分粒子分布函數(shù)的特性，并且由分布函數(shù)得到凈重子數(shù)密度和能量密度。
