网络分析可以通过图的结构来实现，同时，图的平面特征允许面的操作：对于任意的有向弧，只有一个面位于它的右边，一个位于左边。

Any graph which can be redrawn in this way without crossings is called a planar graph,such graphs being of the utmost importance in the theory of graphs.

任何能够按这种方式重画为一个没有交叉线的图称为平面图，这种图在图论中极为重要。

Any graph which can be redraen in this way without crossing is called a planar graph,such graphs being of the utmost importance in the theory of graphs.

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
