anharmonic interaction meaning in English

非简谐作用

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
