摘要：

A transport equation for the turbulent residual helicity is studied for the self-consistent determination of the alpha dynamo effect. For this purpose, a simplified method for analyzing transport effects on mean-field magnetohydrodynamics is presented. Using this method, the mathematical structure of the turbulent residual-helicity equation is examined and its model equation obeying the least minimum requirements is discussed.
