网桥（Bridge）是一种用于绕过网络审查或限制的工具。在Tor网络中，网桥是Tor节点的一种特殊类型，用于帮助用户连接到Tor网络，即使在网络审查存在的情况下也能够绕过限制。

Like ordinary Tor relays, bridges are run by volunteers; unlike ordinary relays, however, they are not listed publicly, so an adversary cannot identify them easily.

在计算机网络中，网桥是一种网络设备，通常用于连接两个或多个局域网（LAN）或网络段，以便它们可以相互通信。网桥工作在OSI（开放系统互连）模型的数据链路层，主要用于在同一网络协议下传输数据帧。

Tor is a program you can run on your computer that helps keep you safe on the Internet. It protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. This set of volunteer relays is called the Tor network.
