【 摘 要 】

As is well-known, in gas dynamics there are three levels of descriptions: microscopic, mesoscopic and macroscopic. The corresponding equations are: Liouville, Boltzmann, and hydrodynamic equations, respectively. The difficulty of condensed matter such as classical liquids is general absence of well-defined mesoscopic level of descrition which is a scaffold so to speak enabling us to jump from microscopic to macroscopic desritions. However, there are certain circumstances in which this is possible as we illustrate for critical dynamics and phase ordering kinetics.
