摘要
第一次，我们介绍一充分量为原子的一个半无限的链模型的机械 Hamiltonian。我们然后由“不变的 eigen 操作员”的优点导出这个模型的颤动模式在二个不同盒子中的方法，它简明、揭示。
For the first time, we introduce a fully quantum mechanical Hamiltonian for a semi-infinite chain model of atoms. We then derive the vibration modes of this model by virtue of the ＂invariant eigen-operator＂ method in two different cases, which is concise and revealing.
