The anharmonic effect of atomic vibration taken into account and from the potential energy which reacts each other among atoms, boltzmann statistical principle used, the relation formula of temperature and the distance change between atoms and coefficient of linear expansion is derived
摘要考慮原子振動的非簡諧效應，從原子間相互作用勢能入手，運用玻爾茲曼統計原理，推出了原子間距的變化與溫度的關系式，並導出了固體的線脹系數。 -
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
