Researches on second nearest neighbor for lattice vibration of one - dimensional diatomic chain 一維雙原子鏈晶格振動中的次近鄰
The lattice vibrations are called phonons ? they behave just like particles , and their emission and absorption by the electrons generate a weak attractive interaction 晶格的振動稱為聲子,它們的行為就像粒子,被電子放射或吸收時會產生微弱的吸引力。
The fluorescence intensity of pb became weak when the crystal phase began to form in tha the lattice vibration absorbed the energy induced by the fluorescent transition 隨著體系中晶態(tài)的生成, pb離子進入晶格中,由于晶格振動所產生的聲子吸收了躍遷回落產生的發(fā)光能量, pb離子的熒光強度明顯下降。

Because the lattice vibration is weak at very low temperature , the contributions of electrics and other low energy excitations become dominant parts of specific heat . therefore , we can study the micromechanism of many physical phenomena from specific heat measurement 在很低的溫度下,由于晶格振動變得很弱,電子和低能激發(fā)貢獻越來越突出,這對我們通過低溫比熱研究很多現象的微觀機制十分有利。
Abstract : considering the second nearest - neighbor interaction and cubic , quartic anharmonic interactions simultaneously , we employ the multiple scales method combined with a quasidiscreteness approximation to calculate the lattice vibration . it is shown that the kind of nonlinear chain exhibits envelope soliton , envelope kink and envelope antikink soliton . these results can also be used to explain the experimental phenomena that the kink amplitude of the self - localized structure is determined only by the intrinsic properties of its lattices 文摘:同時考慮次近鄰諧振相互作用和三次方、四次方非諧相互作用,利用多重尺度結合準離散近似方法去計算晶格振動行為,發(fā)現一維非線性點陣中存在包絡孤子及正扭結型包絡孤子、反扭結型包絡孤子,解釋了自局域結構的幅度只取決于點陣中的固有參數的實驗現象
