| 摘 要： | 本文讨论在背景场量子色动力学框架中的等时方程赝标介子解. 方程的积分核由微扰和非微扰贡献两部分组成．微拔部分是通常的单胶子交换图的贡献；非微扰部分的贡献来自于最低阶的夸克和胶子凝聚效应. 当输入合理的夸克质量参数和耦合常数时，可以得到与实验相符合的赝标介子谱．

| Abstract: | We present the pseudo-scalar solutions of the equal-time equation for the quarkantiquark bound states in QCD in the background fields. The kernel includes both of perturbative and nonpertubative interactions. The perturbative part is usual onegluon exchange, nonperturbative part comes from the contributions of the lowest order quark and gluon condensates. With the reasonable parameters, we obtain the mass spectrum in good agreement with the data. |
