摘要:

The thermal equilibrium electric field fluctuation energy of the gyrokinetic model of magnetized plasma is computed and found to be smaller than the well‐known result ⟨&dgr;E⋅&dgr;E⟩(k)/8&pgr;= 1/2T/[1+(k&lgr;D)2] valid for arbitrarily magnetized plasmas. It is shown that, in a certain sense, the equilibrium electric field energy is minimum in the gyrokinetic regime.
