  The diffusions and anomalous diffusions of charged particles in the plateau
regime of toroidal plasma with a Maxwellian velocity distribution are studied.
The transport theory of plasma is discussed under the toroidal coordinate
system and the magnetic field is assumed to be axisymmetric. Based on the
diffusion flux obtained in the toroidal plasma, we derive the diffusion
coefficient tensor and thermal diffusion coefficient tensor, where two angular
diffusion coefficients are the anomalous diffusions, depending on the radial
position and having nothing to do with the magnetic field. All the radial
transport coefficients and the normal angular coefficients are inversely
proportional to square of the gyrofrequency and so to square of the magnetic
induction. The numerical analyses show clearly dependences of these complex
transport coefficients on the temperature, the magnetic fluid stability safe
factor and the effective collision frequency, respectively.
