第三章研究二阶流体运动的控制方程和平均欧拉方程。

In the third chapter, we consider the equations governing the motion of second grade fluid and averaged equations.

主要考虑外平面图，系列平行图和平面欧拉图这三类特殊的平面图。

In this paper we prove that the problem is polynomial solvable on several special classes of graphs, such as outerplanar graphs, series-parallel graphs and Eulerian planar graphs.
