Separability of Specific Volume and Its Application to Free-Gas Model of Thermoelectrons
-
摘要: 在巨正则统计系综中获得了系统比容可按哈密顿组成拆分的两类系统，即哈密顿完全可分或相互间存在联系的子系统的化学势可由相应的自由能得到。在此基础上讨论了金属自由电子近似模型中热电子对比容的贡献，并给出了相应的吴-经参数。Abstract: Two kinds of systems whose specific volumes can be separated into several parts according to Hamiltonian have been obtained in a grand ensemble. These systems' Hamiltonians are absolutely separable or the chemical potentials of those whose Hamiltonians are not independent can be yielded via respective free energies. On this basis, the partial specific volume contributed by thermoelectrons in metals under a free-gas approximation and the corresponding Wu-Jing parameter are studied as a brief example.
