摘要
Basing on the new method of trajectory stochastic treatment advanced by one of the authors of this paper,the theory of“clumps”in drift-wave turbulence in tokamak plasmas has been developed.It is shown that,as a longer time behaviour,plasmas in tokamaks will have the same“clumps”effects as those in uniform magnetic fields,although the diffusion crossing magnetic field Lines in tokmaks will be enhanced.The influence of the non-uniformity of the magnetic field,such as curvature,shear,etc.,on the transverse diffusion and the“clump”life-time is discussed.
