当存在高频波湍流时，低频微脉动可以强烈调制高频波振幅，导致磁层高能电子损失率出现有限脉动（微脉动振幅较小）。一个极其理想化的模型表明，当微脉动周期小于电子沉淀寿命时，沉淀调制以指数方式依赖于微脉动幅度。
When high-frequency wave turbulence is present, low-frequency micropulsations can strongly modulate the high-frequency wave amplitudes, leading to finite amplitude pulsations in the loss rate of energetic electrons from the magnetosphere (micropulsation amplitude is small). An extremely idealized model suggests that the precipitation modulation depends exponentially on the micropulsation amplitude, when the micropulsation period is less than the electron precipitation lifetime.
