摘要
说明二维非定常与三维定常比拟准则存在着一些内在的矛盾，进而说明用Ｌａｇｒａｎｇｅ方法揭示的二维非定常分离应该用染色线而不应用轨线来解释。
It is shown that there are some discrepanicies in the analogy criteria of two dimensional unsteady separation and three dimensional steady separation. Furthermore, based on Lagrangian method to describe fluid motion, the unsteady separation phenomenon could be explained by means of streaklines rather than path lines.
