这个翻译太要命

只列举了后面的翻译问题，实在忍不了了。前面也有问题，不过我没做记录。

c is able to observe the update u’ only by, say, reading /b after receiving the notification corresponding to u.

如果u和u'分别修改了/a节点和/b节点，其中客户端c在/a节点设置 了监视点，c只能观察到u'的新，即接收到u所对应通知后读取/b节 点。

In both cases, XXX can be anything as long as there are no other auth Providers with the same XXX.

这两种情况下，XXX 可以为任意值，只要没有任何重名的authProvider，

Although the discussion so far has focused on the case where the client crashes, all the points in this section apply also when the session has simply expired.

尽管到目前为止我们讨论的都是客户端崩溃的案例，本节中还需要讨论会话过期的问题。
