导出了一般非均匀磁化等离子体中相对论性带电粒子的一组自洽非线性陀螺动力学方程。考虑了由低频陀螺动力学排序给出的空间和时间尺度的全电磁场波动。将非线性相对论性陀螺动力学Vlasov方程与低频麦克斯韦方程（其中电荷密度和电流密度用陀螺动力学Vlasov分布的矩表示）结合得到自洽性。对于这些自洽回旋动力学方程，导出了低频能量守恒定律。
A set of self-consistent nonlinear gyrokinetic equations is derived for relativistic charged particles in a general nonuniform magnetized plasma. Full electromagnetic-field fluctuations are considered with spatial and temporal scales given by the low-frequency gyrokinetic ordering. Self-consistency is obtained by combining the nonlinear relativistic gyrokinetic Vlasov equation with the low-frequency Maxwell equations in which charge densities and current densities are expressed in terms of moments of the gyrokinetic Vlasov distribution. For these self-consistent gyrokinetic equations, a low-frequency energy conservation law is also derived.
