图7中，我们在时间框架中额外添加了一个用户访问文件来表示所提供的文件访问模式—用户以读模式还是以写模式访问。

In Figure 7, we've added a field in addition to the time frame a user accesses the file to represent in which mode the file access is provided - whether the user is accessing for write or for read.

但其他用户能以读模式访问文件。

But other users can access the file in read mode.

一般来说，如果两个或多个用户以写模式并发访问文件，第一个用户保证能以写模式访问文件，其他用户的写模式访问请求将排队。

In general, if two or more users access the file in write mode concurrently, the first user is granted write mode access to the file and the remaining users write mode access requests are queued.
