1·It was observed that their phonon spectra vary with their hydrogen content.

观察到了它们的声子谱随含氢量而变化以及声学支有规则的软化现象。

2·This course has a three part group project assignment which covers the (1) physical structure, (2) the phonon spectra, and the (3) band structure of a semiconductor.

本课程含有一个具有三个组成部分的小组设计作业，覆盖半导体的：（1）物理结构，（2）声子谱，以及（3）带结构。

3·Origins of other phonon modes in the spectra are discussed as well.

对光谱中的其他声子模式的起源也进行了讨论；

4·The X-ray diffraction (XRD), excitation, emission and phonon side band spectra of the upper and lower parts of crystals were measured.

测定了晶体下部与上部的X射线衍射图（XRD）、激发光谱、荧光光谱以及声子边带谱。

5·The low-lying spectra of a quantum dot, where the two electrons interact with each other under a magnetic field, and the effect of electron-phonon interactions to the spectra are discussed.

研究了磁场下量子点中二电子系统的低激发态能谱，考察了电子-声子相互作用对能谱的影响。
