Strong Triadic Closure Property is that if a node has strong ties to two neighbors, then these neighbors must have at least a weak tie between them. A local bridge occurs, on the other hand, when a node is acting as a gatekeeper between two neighboring nodes who are not otherwise connected. In a network that follows the Strong Triadic Closure Property, one of the ties between nodes involved in a local bridge needs to be a weak tie.

强三元闭包性指，如果一个节点与两个邻居具有强联系，则这些邻居之间必须至少有一条弱联系。另一方面，当某节点在两个互不相连的邻居间充当'''<font color="#FF8000">中间人 Gatekeeper</font>'''时，则将产生局部桥。在遵循强三元闭包性质的网络中，局部桥涉及的节点之间的联系必然至少包括一条弱联系。
