| 摘 要： | 本文通过在三波相互作用的耦合方程中加进衰减项,同时对复振幅进行一个相位变换得到了有相位变化和衰减的三波相互作用耦合方程。解这些方程得到了孤波解。最后讨论了相位变化和衰减对孤波的影响,得到了一些有趣的结果。

| Abstract: | In this paper we obtained the coupled equations of three-wave interaction, which include phase variations and attenuations by adding the attenuation term to the coupled equations in Ref.1] and playing a phase transformation to the complex amplitude, Sloving these equations we got the solitary waves solutions. At last we discussed the effects of phase variations and attenuations on the solitary waves in three-wave interactions and obtained some interesting results. |
