摘要：

A self-consistent theory of finite-e universal-mode turbulence is developed. Saturation results from resonance broadening of the electron response due to magnetic shear. Electron diffusion, for e>memi, is due to the magnetic part of the fluctuations. The diffusion coefficient, D=0.1 [Te(Ti+Te)]4(memie)(LsLn)2vii2Ln, scales inversely with density, is independent of magnetic field, and is in excellent quantitative agreement with observations on the Alcator tokamak. © 1979 The American Physical Society.
