漂移效应在日光层中带电粒子的传输中起着重要作用。众所周知，湍流磁场可以减少粒子漂移的影响。然而，这种减少的确切性质尚不清楚。本研究旨在提供对这种减少的一些见解，并提出一种相对简单、易于处理的建模方法，该方法提供的结果与湍流磁场中漂移系数的数值模拟合理一致。
Drift effects play a significant role in the transport of charged particles in the heliosphere. A turbulent magnetic field is also known to reduce the effects of particle drifts. The exact nature of this reduction, however, is not clear. This study aims to provide some insight into this reduction and proposes a relatively simple, tractable means of modeling it that provides results in reasonable agreement with numerical simulations of the drift coefficient in a turbulent magnetic field.
