研究了一维半线性双曲型方程组在小扰动下高频振动的传播。我们得到一个新的退化抛物型方程组的轮廓，有效的渐近发展的精神Joly，Metivier和Rauch。
We study the propagation of high frequency oscillations for one dimensional semi-linear hyperbolic systems with small parabolic perturbations. We obtain a new degenerate parabolic system for the profile, and valid an asymptotic development in the spirit of Joly, Metivier and Rauch.
