摘要
本文用摄动法导出了非线性弦振动的K-dV方程,讨论了只有耗散和色散的特殊情况,然后详细讨论了K-dV方程的孤波解的性态,并给出了非线性弦振动孤波的主要特征.
This,paper derives the K-dV equation in thevibration of nonlinear string by meane of Pertutbation method.The specific case with only dispersive or dissipation is discus-sed,Then the properties of the solutions of solitarv waves inK-dV equation are stated in more detail, and the main features ofthe solitary waves iu K-dV equation are stated in more detail, andthe main features of the solitarv waves in nonlinear string aregiven.
