| Abstract: | Based on the definition of entropy, the three probability distribution functions are deduced in microcanonical ensemble, canonical ensemble, grand canonical ensemble. And the definition of entropy is discussed and widely utilized in the ensembles. In the end, the thermodynamical property of the ensembles are discussed. |
