我们表明，线性碰撞过程不阻尼极向流驱动的离子温度梯度（ITG）湍流。由于这些流动在饱和湍流水平中起着重要的作用，因此采用线性无碰撞旋转阻尼的陀螺流体模拟可能会高估该水平以及ITG模式引起的运输。{版权} {美国物理学会}
We show that linear collisionless processes do not damp poloidal flows driven by ion-temperature-gradient (ITG) turbulence. Since these flows play an important role in saturating the level of the turbulence, this level, as well as the transport caused by ITG modes, may be overestimated by gyrofluid simulations, which employ linear collisionless rotation damping. {copyright} {ital 1998} {ital The American Physical Society}
