内容記述(抄録等)
Langevin's equation as an adequate description of Brownian motion is applicable in large variety of systems which are close to equilibrium. For these systems hydrodynamic equations describe the long wave-length, Iow-frequency phenomena. The equation of motion for these systems of continuous media is generalized to the similar type of Langevin equation and correlation of fluctuation is discussed.
