本文第一部分综述了不可压缩流中后掠机翼过渡的预测方法，给出了简单的过渡准则，并讨论了将众所周知的Ender方法扩展到三维情况的可能性。本文第二部分给出了这些不同技术的应用；通过对转折点实测值和预测值的比较表明，关键问题在于稳定性特性从横流方向向流向方向的演变。
The first part of this paper is concerned with a survey of the methods which can be used for predicting transition on swept wings, in incompressible flow; simple transition criteria are presented and possible extensions of the well known enmethod to three-dimensional situations are discussed.Applications of these various techniques are given in the second part of the paper; comparisons between measured and predicted transition locations indicate that the key problem lies in the evolution of the stability characteristics from the crossflow direction to the streamwise one.
