- 論文の詳細を見る
Statistical analysis is made of effects of homogeneous turbulence upon magneticfield, in a close relation to the magnetic-dynamo problem. Using a statistical-mechanical approach developed in the study of inhomogeneous non-magneticturbulence, a formula is found for the mean electromotive force playing animportant role in dynamo theory. The so-called a-effect, in special, is expressedin a simple form under the pseudo-isotropic turbulent field whose statisticalproperties have an exponential time dependence.
