简谐晶体高温比热的量子修正

The Quantum Correction of High Temperature Heat Capacity for Harmonic Crystal

爱因斯坦假设和德拜假设采用量子论处理了晶格的低温热容问题,而高温部分晶格的热容仍然采用的是传统的隆-帕替定律。本文在对晶格热容的高温温区处理上,考虑到量子效应,对点阵的高温热容加以了量子修正。

The heat capacity of lattice for low temperature zone was developed by Einstein and Debye by using quantum method,while the heat capacity for high temperature zone still adopts the conventional Dulong-petit law.In this paper,we develop the quantum correction for the heat capacity of lattice for high temperature zone.
