将一个网络A嵌入到另一个网络B中是指将A中的各节点映射到B的节点。

膨胀系数（Dilation）膨胀系数是指被嵌网络在主嵌网络中对应的边数（即链路数）。如果系数为1，则称为完美嵌入。例如，2-D环绕可完美嵌入到超立方体连接中去。

In computer science, transclusion is the inclusion of part or all of an electronic document into one or more other documents by hypertext reference. Transclusion is usually performed when the referencing document is displayed, and is normally automatic and transparent to the end user. The result of transclusion appears to be a single integrated document, although its parts were assembled on-the-fly from various separate sources, possibly stored on different computers located in disparate places.
