Researches on second nearest neighbor for lattice vibration of one - dimensional diatomic chain 一维双原子链晶格振动中的次近邻
The lattice vibrations are called phonons ? they behave just like particles , and their emission and absorption by the electrons generate a weak attractive interaction 晶格的振动称为声子,它们的行为就像粒子,被电子放射或吸收时会产生微弱的吸引力。
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 随着体系中晶态的生成, pb离子进入晶格中,由于晶格振动所产生的声子吸收了跃迁回落产生的发光能量, pb离子的荧光强度明显下降。

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 在很低的温度下,由于晶格振动变得很弱,电子和低能激发贡献越来越突出,这对我们通过低温比热研究很多现象的微观机制十分有利。
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:同时考虑次近邻谐振相互作用和三次方、四次方非谐相互作用,利用多重尺度结合准离散近似方法去计算晶格振动行为,发现一维非线性点阵中存在包络孤子及正扭结型包络孤子、反扭结型包络孤子,解释了自局域结构的幅度只取决于点阵中的固有参数的实验现象
