Researches on second nearest neighbor for lattice vibration of one - dimensional diatomic chain 一維雙原子鏈晶格振動(dòng)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(dòng)稱為聲子,它們的行為就像粒子,被電子放射或吸收時(shí)會(huì)產(chǎn)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(jìn)入晶格中,由于晶格振動(dòng)所產(chǎn)生的聲子吸收了躍遷回落產(chǎn)生的發(fā)光能量, pb離子的熒光強(qiáng)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(dòng)變得很弱,電子和低能激發(fā)貢獻(xiàn)越來(lái)越突出,這對(duì)我們通過(guò)低溫比熱研究很多現(xiàn)象的微觀機(jī)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(shí)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(jié)合準(zhǔn)離散近似方法去計(jì)算晶格振動(dòng)行為,發(fā)現(xiàn)一維非線性點(diǎn)陣中存在包絡(luò)孤子及正扭結(jié)型包絡(luò)孤子、反扭結(jié)型包絡(luò)孤子,解釋了自局域結(jié)構(gòu)的幅度只取決于點(diǎn)陣中的固有參數(shù)的實(shí)驗(yàn)現(xiàn)象
