摘要：

Using the differential effective medium approach, the diffusivity, chi(e), of a weakly collisional plasma confined by a magnetic configuration close to the stochastic threshold is estimated. With a good approximation, one gets chi(e) approximately chi(perpendicular-to)/f, where chi(perpendicular-to) is the diffusivity in the KAM region with undestroyed magnetic surfaces and the fraction of these regions.
