【摘要】 本文应用多重尺度微扰方法研究了双线或同轴传输线中传播波的非线性调制,导出了波振幅所满足的非线性schrodinger方程,并给出了包络孤波解,这对于电力传输问题的研究是有帮助的。更多还原

【Abstract】 In this paper, we study the nonlinear modulation of the propapating wave in double or the same axial transmission lines by using multiple seals peturbation method. A nonlinear Schrodinger equation representing the wave amplitude action is derived, and the envelope soliton of the NLS squation is qiven. It is helpful to the study on the problem of electric power transmission.更多还原
