这与硬盘不同，硬盘是文件和东西永久存储的地方。
This is different from the hard disk, which is where files and stuff are permanently stored.
这种永久数据就是文件数据。
如果应用程序对某个文件进行写操作(而不是读操作)，那么永久存储分页将是“经过修改的”，并且AIX必须在释放这些分页之前将其刷新到磁盘。
If the application had been doing writes to the file instead of reads, the permanent storage pages would be "modified," and AIX would have to flush the pages to disk before releasing the pages.
因此，永久存储分页就是缓存在内存中的部分文件。
So, permanent storage pages are basically just pieces of files cached in memory.
您仍需要一些数据文件的永久存储。
You will still require some permanent storage for your data files.
因此，内存中的永久存储分页与磁盘中的文件数据完全相同。
So, the in-memory permanent storage pages are equivalent to the file data on the disk.
当经过修改的永久存储分页需要换出(从内存移动到磁盘)的时候，会将它写入到文件系统中。
When a modified permanent storage page needs to be paged out (moved from memory to disk), it is written to a file system.
比如，我们可以把它作为一个，附加的功能，这样人们可以，选择打印永久性的文件或者暂时使用的文件。
We're gonna just make it, for example, as an extra feature so people can either choose to print the permanent document or temporary document.
如前所述，可以直接释放没有经过修改的永久存储分页，无需将其写入到文件系统中，因为文件系统包含该数据的原始副本。
As mentioned earlier, an unmodified permanent storage page can just be released without being written to the file system, since the file system contains a pristine copy of the data.
存储在这里的文件应该被认为是临时的，因为每个实例的文件系统不是永久的。
Files stored here should be considered temporary because each instance's file system is ephemeral.
随着程序对该文件进行读写操作，AIX内核将该文件的数据作为非计算性的永久存储分页在内存中进行缓存。
As a program does reads and writes to the file, the AIX kernel caches the file's data in memory as non-computational permanent storage pages.
如果关闭该文件，那么AIX内核将继续在内存中(在永久存储分页中)缓存该文件的数据。
If the file is closed, the AIX kernel continues to cache the file data in memory (in permanent storage pages).
由于在很多基于Linux的嵌入式系统上没有硬盘，因此initrd也会作为这种系统上的永久根文件系统使用。
Because there is no hard drive in many embedded systems based on Linux, the initrd also serves as the permanent root file system.
仅永久储存文件系统inode,dentry对象的目的是改善性能。
Only file system inodes are stored permanently, where dentry objects are used to improve performance.
按住shift键的同时点击删除按钮可以永久删除文件。
Hold the Shift key when clicking the delete button to permanently delete a file.
如果想作永久的更改，则必须更新emacs初始化文件。
If you prefer to make a permanent change, you have to update your Emacs initialization file.
如名称所示，varnishd文件是varnish守护进程——缓存和服务来自内存的内容的永久服务。
The file varnishd, as its name implies, is the varnish daemon - a perennial service that caches and serves content from memory.
提示：要想自动地添加所有新文件并且把已经删除的所有文件标为永久删除，可以使用Mercurial的hgaddremove命令。
Tip: to add automatically all new files and mark any files that have been removed for permanent removal, you can use Mercurial's handy hg addremove command.
当对某个文件出现进程缺页(意味着该进程引用了文件的部分内容，而这部分内容当前没有缓存在永久存储分页的内存中)的时候，该进程将产生一个缺页。
When a process page faults on a file (meaning the process references a part of the file that is not currently cached in memory in a permanent storage page), the process generates a page fault.
如果您具有不需要长期永久保存的临时文件，那么可以将这些文件存储在高速缓存中。
If you have temporary files that do not need long-term persistence, you can store those files in a cache.
若要永久地将交换空间添加到系统，您必须配置启动配置文件之一来自动启用交换空间分配。
To add the swap space permanently to your system, you must configure one of the boot configuration files to enable the swap allocation automatically.
通过使用一种易于实现和维护的选择，您可以通过点击按钮来更改显示语言，而不需要对用户概要文件进行永久性的更改。
Using an option that is easy to implement and maintain, you can change the display language by clicking a button without making a permanent change to the user profile.
如果一个文件包含某个进程的可执行文本，那么系统会将该文件视为计算性的，并且将该文件中的所有永久存储分页都标记为计算性的。
If a file contains executable text for a process, the system treats the file as computational and marks all of the permanent storage pages in the file as computational.
如果该文件不包含可执行文本，那么系统会将该文件视为非计算性的，并且将该文件中的所有永久存储分页都标记为非计算性的。
If the file does not contain executable text, the system treats the file as non-computational file and marks all of the pages in the file as non-computational.
例如，如果一个应用程序正在读取某个文件，那么该文件数据将缓存于永久存储分页的内存中。
For example, if an application is reading a file, the file data is cached in memory in permanent storage pages.
除非你使用非常原始的邮件系统，否则它都会提供一个功能(通常叫“文件夹”)来永久保存邮件，方便日后随时查看。
Unless you have a very primitive E-mail system, it probably has some system (usually called "folders") that can be used to permanently store messages for recall at any time in the future.
另一种模式是让用户订阅实际上是自助内容的视频，随后将视频通过流媒体技术载入电脑中，但不留下永久的备份文件。
The other approach is to let users subscribe to what is, in effect, an all-you-can-eat buffet of videos, and then to “stream” video to their computers without leaving a permanent copy.
用户不能永久储存文件或者文件夹。
The user should not be able to permanently store files or folders.
应用程序依赖XML文件来进行数据交换以及关系数据库来提供数据永久性都是应用程序业务逻辑(也就是其模式)的特征。
An application's reliance on XML documents for data exchange and relational databases for data persistence are characteristics of the application's business logic (that is, its model).
档案雨刮器-安全工具让你可以删除任何文件永久没有复苏。
