两部图的计数

Two picture count

图论是数学的一个分支,它以图为研究对象,研究节点和边组成的图形的数学理论和方法。图论中的图是由若干给定的点及连接两点的边所构成的图形,这种图形通常用来描述某些事物之间的某种特定关系及事物,用连接两点的边表示相应两个事物间具有这种关系。图论的研究对象相当于一维的拓扑学。标定图的计数是图的计数的基础,了解两部图的计数,在实际运算中可以减少许多不必要的盲目性。标定两部图的数目和独立结点、边的数目是两部图中的重要概念。

The graph theory is mathematic a branch,it regarding diagram as the sketch's mathematics theories that the research object,research node constitute with the side with the method.The graph in the graph theory is a point and side of conjunction two that be settled by somely to the side for sketch for constituting,this kind of sketch usually using to of describing some things thing for of a certain and praticular relation,using linking two mean two things of cowgirls to have this kind of relation.The Graph theory that research object that is equal to the a dimension Topology.What mark picture count is the enumerated foundation of picture,know two pictures count,reducing a lot of unnecessary blindness in actual operation.This paper discusses and independent node that marks the number of two pictures and the number of side.
