摘　　要：用在电磁等离子体中广泛证明有效的导数展开法求解夸克胶子等离子体动力论方程，发现场方程的自作用项对夸克胶子等离子体的非Ａｂｅｌｉａｎ激发的非线性频移具有非常重要的影响．求解到第三阶，得到了包含胶子自耦合作用的非线性频移的解析表达式，并给出了ｋ＝０模式的纯胶子气的非线性频移的数值解．The derivative expansion method is used to solve the kinetic equations of quark-gluon plasma. In the process of solution, we find that the self-interaction term of the mean field equation plays an important role to the nonlinear eigenfrequency shift of the non-Abelian excitations in quarkgluon plasma. To the third order of derivative expansion, we get the general analytical expression of nonlinear frequency shift including the self-interaction in the leading order of coupling constant and give out the value of eigenfrequency shift for the pure gluon plasma to the important k = 0 modes.
