摘要
采用界面重标度方法，严格求解了对称Ａ－Ｂ－Ａ结构的原子晶格链中晶格振动的界面态的本征值问题，获得了界面态存在的充分必要条件的精确解析式．
he exact solutions of interface state eigenvalue problems of lattice vibrations in a monoatomic chain of symmetry A-B-A structure are investigated by use of the interface rescaling approach. The necessary and sufficient condition for the existence of such interface states is obtained exactly and analytically.
