| 1. | A circ is an undirected graph having only vertices of even nonzero degree .
一广义圈是一无向图，其顶点次数都是非零偶数。 |
| 2. | To avoid detail we shall use the latter symbol for both undirected and directed graphs and rely on the context for clarity .
为了避免琐碎，对无向图和有向图我们都采用后一符号，而靠上下文加以澄清。 |
| 3. | All graphs under consideration are undirected and finite
本文所考虑的图皆指有限无向图且无环。 |
| 4. | Several reliability preserving reductions for the graph g are given
