从相空间守恒回旋运动公式出发，平行动量守恒的系统推导揭示了微湍流驱动内旋转的新机制。这种机制通过并联非线性出现在回旋运动公式中，是由于极化漂移引起的电荷分离而出现的。该机制的推导和物理讨论将在整封信中进行。
Starting from a phase space conserving gyrokinetic formulation, a systematic derivation of parallel momentum conservation uncovers a novel mechanism by which microturbulence may drive intrinsic rotation. This mechanism, which appears in the gyrokinetic formulation through the parallel nonlinearity, emerges due to charge separation induced by the polarization drift. The derivation and physical discussion of this mechanism will be pursued throughout this Letter.
