非线性波动系统的冲击层解
ShockLayerSolutionofNonlinear WaveSystem
摘要
Abstract
Weconsideredthethirdboundaryvalueproblem ofnonlinearsingularlyperturbed wave equation.Firstly,the outer solution was constructed by using singular perturbation method. Secondly,correctiontermsoftheshocklayer,initiallayerandboundarylayerwereobtainedbyusing thestretchedvariables.Finally,theasymptoticexpansionofsolutiontoproblem wasgiven,andthe uniformvalidityofitsasymptoticsolutionwasproved.关键词
