各向同性晶体

For non-diagonal processes there is "Coherent enhancement" therefore the one-phonon processes are more important than the two-phonon processes; At the same time, we presented a new theoretical framework of phonon-assisted energy transfer, in which the running lattice wave theory is introduced instead of the Debye theory for phonons,therefore emphasizes the important effects of optical phonons and coherence effects of anisotropic lattice waves etc.

非对角过程中的干涉是相加的，因而首先应考虑单声子而非双声子过程；接着，用计及原子尺度上晶体结构的&格波模声子&取代各向同性连续介质模型中&德拜声子&来描述所涉声子，提出了新的声子协助的能量传递理论，指出了德拜模型中没有的&光学声子的重要性&和&各向异性的格波干渋&等新视点。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
