我们发现了一类具有非线性响应漂移机制的光折变介质中多分量部分相干孤子的精确解。它们的新颖之处在于复合m分量的锯齿形孤子位于恒定背景平面波上。解的特征是两个自由参数，这两个参数与复合孤子的最大强度和背景的振幅有关。[s0031 - 9007 (99) 08778 - 5]
We have found a new class of exact solutions for multicomponent partially coherent solitons in photorefractive media with a drift mechanism of nonlinear response. Their novel feature is that the composite M-component sech-shaped soliton is located on a constant-background plane wave. The solutions are characterized by two free parameters and these are related to the maximum intensity of the composite soliton and to the amplitude of the background. [S0031-9007(99)08778-5]
