A New Model of Statistical Laws of Solids
余子山 ：徐州市农委，江苏 徐州
The conclusions of the existing statistical models, such as Debye model and Einstein model, lack of scientificity for departure from the solid intrinsic energy laws badly. The statistical laws of solids are re-studied and a new model is founded. Some original viewpoints, especially in low temperatures, are acquired. It is considered that atomic mass and temperature affect greatly on the scopes of energy levels, state density function, state number and atoms distribution etc. In low temperatures, the energy scope is very narrow; the highest energy level EU is smaller than kT; possible state number is few; thermal capacity is in (direct) proportion to temperature. And the potential energy’s affections on scope of energy levels, state density function, state number, and thermal capacity are more notable than the kinetic energy’s affections. In high temperatures, the ratio of the effective volume of atomic nucleus motioning, a new concept defined, to the solid volume is researched. Besides, the basic problems, such as thermal capacity, are studied.
