摘要
用热传播子的实时形式对高温条件下夸克（忽略质量）场三圈真空图进行了详细地计算，找出了其中和费米-狄拉克统计因子有关的红外发散积分的类型，并对这种发散积分进行了正规化，进一步把真空图中的红外发散全部孤立出来了．
The infrared divergences in vacuum graghs of quark (ignored mass) field at high tempethere are calculated in detial by real-time formulation of Green function, a kind of infrared divergent integral related to F-D statistical factor is pointed out and its regularization is discussed. All of the infrared divergences in three-loop vacuum graghs of quark field are isolated.
