statistical physics
2.The relation of empty cellar radiation energy density and absolute temperature is derived through Thermody- namics and Statistical Physics two methods, the ones that thus state Thermodynamics and Statistical Physics are unified.
3.As molecular motor lies in liquid environment, it can be regarded as Brownian particles or Brownian rachet in physics, and its motion can be classified into theoretical frame of Brownian movement, analyzed and calculated by Langenvin equation or Fokker-Plank equation in nonequilibrium statistical physics.
4.“In the present context, criticality and self-organized criticality, used in the sense of statistical physics, refer to two very different concepts, which leads to a lot of confusions, as seen in this debate.
5.From electrooptic effect, light quantum theory, Compton scattering effect and the matter wave of De Broglie and its statistical law, the teaching method on waveparticle duality in university physics is discussed.
