anharmonic ratio

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
