collision integral造句

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。
