| 摘 要： | 本文首先提出一个新的‘人工来流振荡’模型，在此基础上建立了跨声速叶栅多工况点气动反命题的变域变分理论，可以保证叶栅在相当广阔的变工况范围内都能保持优良的运行特性。本理论的突出优点是可较直捷地推广到全三维流动和有旋流动中去，因而具有广阔的发展与应用前景。

| Abstract: | A variational formulation of the entitled problem based on an artificial flowoscillation concept is presented,enabling cascades to be designed with favorable performancein a wide range of off-design conditions. The theory can be readily extended to 3-D androtational flows. |
