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，从有碰撞项的qgp动力论方程出发，忽略自旋，在色涨落扰动下，利用弛豫时间近似，得到夸克和胶子分布函数的二级修正，通过数值分析重点讨论了高温低密情况下qgp中成分粒子分布函数的特性，并且由分布函数得到净重子数密度和能量密度。
As the time microscale factor in fast transient high - strength heating or cooling can not been ignored , heat relaxation time is introduced . based on hyperbolic heat conduction equation and kinetic equation added inertia , theoretical analysis and study of stress diffusion and transformation in heat impact process were developed 考虑到快速高强度加热或冷却带来的时间微尺度因素，引进热松弛时间，以双曲线型热传导方程和考虑惯性力的运动方程为基础，对热冲击过程的应力传播与变化规律进行了理论上的分析和研究。
According to gaseous " molecular kinetic , the mass diffusion rate is within finite value . so theoretical conclusion of mass flux ' s producing and the essential relation of flux vs . force could be drawn . with the assumption that local density states in near equilibrium and the distribution is gradual changed , the classical first pick ' s law was modified considering mass relaxation time 根据气体分子运动论对质量传播速度为有限值情况下的质量流的产生及流与力之间的本构关系作了理论推导，在假定局域浓度处于近平衡态，其分布为渐进的情况下得到了考虑质量松弛作用的经典fick第一定律的修正式。
