网络图结点的编号方法

Study on Network Event Numbering Method

以网络拓朴逻辑和网络图绘制原则为基础，阐述了网络图结点编号所遵循的一般规律，进而给出了进行网络图结点编号的基本方法，从网络始结点起沿着箭线方向，在一个结点编号后，去掉由其发出的所有箭线，然后再从剩余的网络图中找到没有箭线进入的结点，给它编一个较已编过的号更大的号。

On the basis of network topology logic and network drawing principle,the general rule and method of the network event numbering are put forward. That is, from the start event, the events are numbered following the arrow's direction and all arrows leaving from the numbered event are deleted, then finding and numbering an event with no arrow entering it in the rest network till the final event.
