双语例句
- Some corollaries on tutte's theorem
Tutte定理的几个推论 - Tutte's result can be views as a generalization of Whitney's result since any maximal planar graph with at least five vertices and with no separating triangles is 4-connected.
不含有分离三角形的极大平图是4连通图，因此Tutte的结果可以看作是Whitney结果的一个推广。 - This paper proves that counter example of Heawood is four-color by using Tait's methods, counter example of Tutte is also four-color by using Kempe's chains.
该文用Tait方法证明了Heawood反例是四色的；用Kempe链方法证明了Tutte反例也是四色的。 - Note that if a maximal planar graph has separating triangles, then it can not be 4-connected and therefore Tutte's result can not be applied.
注意到：一个极大平图若含有分离三角形，则其不是4连通的，因此不能运用Tutte的结果。 - Part two presents background and plots of Cosi fan tutte, and then analyzes and compares roles in the operas.
