With this method, the nextto-leading order Debye screening mass was evaluated within real time hot QCD. Since the gluon damping rate was included self-consistently on the internal line of the self-energy, the infrared divergences were removed without putting by hand in a nonperturbative magnetic mass as a cutoff, and the results are positive and gauge-independent. In addition, the selfconsistent calculation method of the damping rates of the fast moving particles in a QGP was suggested, the self-consitent equations were derived at finite tempeature without infrared divergences, and the approximation solutions were shown. Meanwhile the relaxation times of the gluons and quarks were estimated as τ〓～0.7fm/c and τ〓～1.5fm/c at energy scales of RHIC and LHC.

用这种自洽方法从实时热QCD出发用计算了QGP中次带头阶Debye屏蔽质量，由于自洽包含了胶子自能内线中横胶子的衰减率，克服了红外发散的困难，不必用手加的非微扰磁质量作截断，证明了得到的结果是正定的且规范无关，同时本文给出了QGP中快速粒子衰减率的自洽计算方法，推出了有限温度下快速粒子衰减率的自治方程且红外发散不出现，给出了方程的近似解，并估计了RHIC和LHC能标下胶子和夸克的弛豫时间分别为τ〓～0.7fm/c，τ〓～1.5fm/c。
