Abstract:	本文主要目的是對平面凸角扇形膨脹波之普朗特-梅耶二氏流中,超音速微小擾動之理論重新加以分析和驗證。利用Strained Coordinates方法,從普朗特-梅耶二氏流邊界值問題中推導得知,超音速一階微小擾動方程式是非線性的。超音速非線性漸近理論所得之結果非常有趣且與普朗特 -梅耶流之確解相當接近。 The essential point of view introduced here is to re-examine the Supersonic Small Perturbation Theory of centered Prandtl-Meyer expansion. By using the method of Strained Coordinates, the first - order approximate equation to the boundary-value problem of the Prandtl-Meyer flow is found to be nonlinear. The supersonic nonlinear theory gives some interesting results and agrees well with the exact solution of Prandtl-Meyer expansion.
