Near-resonant energy transfer to large-scale stable modes is shown to reduce transport above the linear critical gradient, contributing to the onset of transport at higher gradients. This is demonstrated for a threshold fluid theory of ion temperature gradient turbulence based on zonal-flow-catalyzed transfer. The heat flux is suppressed above the critical gradient by resonance in the triplet correlation time, a condition enforced by the wave numbers of the interaction of the unstable mode, zonal flow, and stable mode.

通过近共振能量转移降低阈值热通量

研究表明，近共振能量转移到大规模稳定模式可以减少线性临界梯度以上的传输，从而有助于在较高的梯度下开始传输。基于基于纬向流催化转移的离子温度梯度湍流的阈值流体理论证明了这一点。通过三重态相关时间中的共振将热通量抑制在临界梯度以上，该条件由不稳定模式，纬向流和稳定模式的相互作用的波数所强制。
