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.
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 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.
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。
So, the in-memory permanent storage pages are equivalent to the file data on the disk.
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。
If the file is closed, the AIX kernel continues to cache the file data in memory (in 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。
For example, if an application is reading a file, the file data is cached in memory in permanent storage pages.
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。
The data should be transformed and stored in file systems or databases to be permanent.
若要把暂态对象永久保留，就必须把对象转换成一定格式的数据存储在文件或数据库中。
