| 3. | 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。 |
| 4. | 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。 |

| 7. | 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。 |
| 8. | 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 |
