一维单原子链振动能与热容的研究

摘要

The lattice vibration energy and heat capacity can be accurately solved in one-dimensional atomic chain, comparing them with the lattice vibration energy and heat capacity of Einstein model and Debye model,the advantages and disadvantages of the models can be find out. The analysis is done to deepen the understanding of the models and to help us in improving the models.%对于一维晶格可以严格求出振动能和热容,将它们与爱因斯坦模型和德拜模型的结果进行比较,可以找出两种模型的成功与不足,如此可以加深对模型的理解,也有助于模型的完善.
