摘要

一个简单的模型，基于一个谐振子粒子在笼形物笼内的行为，调整填充原子的振动频率作为笼大小的函数，用于不同作者制备的不同类型的i型笼形物化合物，使我们能够提取有关电荷转移的结论，“响尾蛇”和包含笼之间的关系，也可以预测，对于给定的网络组成，哪些原子对散射某些声子频率有用。

Getting rid of acoustic phonons in heat transport

A simple model based on the behavior of a harmonic oscillator particle inside a clathrate cage that adjusts the vibration frequency of filler atoms as a function of the cage size for different type-I clathrate compounds prepared by different authors allows us to extract conclusions regarding charge transfer, relationships between "rattler" and containing cage and also, to predict, for a given network composition what atoms would be useful to scatter certain acoustic phonon frequencies.
