摘要: After a brief review of dynamic correlations in equilibrium fluids, we consider the long-range between fluctuations fluid subjected to large stationary temperature gradient. These enhance and modify Rayleigh spectrum fluid. We elucidate that modifications line are determined by coupling entropy transverse velocity fluctuations. Recent attempts test theoretical predictions with aid light-scattering experiments discussed.
