摘要：

Global gyrokinetic simulations of turbulence include physical effects that are not retained in local flux-tube simulations. Nevertheless, in the limit of sufficiently small rho(*) (gyroradius compared to system size) it is expected that a local simulation should agree with a global one (at the local simulation radius) since all effects that are dropped in the local simulations are expected to vanish as rho(*)-->0. In this Letter, global simulations of a well-established test case are indeed shown to recover the flux-tube limit at each radius. (C) 2004 American Institute of Physics.
