Starting from the spectral representation of quasi-particles, when Debye screening mass and finite width of the particle are taken as parameters into the spectral functions, we will get effective propagators of quarks and gluons, and then establish the effective perturbation theory which reflects directly collective effects in QGP, and analyse some thermodynamics problems about soft partons in QGP.

接着，从准粒子的谱表示出发，自洽地将Debye屏蔽质量和粒子的有限宽度作为参量纳入QGP中玻色型和费米型准粒子的谱函数，得到夸克胶子等离子体中胶子和夸克的有效传播子，进而建立了直接反映QGP集体效应的有效微扰论，藉此一般性地分析了夸克胶子等离子体中软粒子的有关热力学问题。
