-[section:emulation Emulation for systems without shared memory objects]
-[*Boost.Interprocess] provides portable shared memory in terms of POSIX
-semantics. Some operating systems don't support shared memory as defined by
-* Windows operating systems provide shared memory using memory backed by the
-   paging file but the lifetime semantics are different from the ones
- defined by POSIX (see [link interprocess.sharedmemorybetweenprocesses.sharedmemory.windows_shared_memory
-   Native windows shared memory] section for more information).
-* Some UNIX systems don't fully support POSIX shared memory objects at all.
-In those platforms, shared memory is emulated with mapped files created
-in a "boost_interprocess" folder created in a temporary files directory.
-In Windows platforms, if "Common AppData" key is present
-in the registry, "boost_interprocess" folder is created in that directory
-(in XP usually "C:\Documents and Settings\All Users\Application Data" and
-in Vista "C:\ProgramData").
-For Windows platforms without that registry key and Unix systems, shared memory is
-created in the system temporary files directory ("/tmp" or similar).
-Because of this emulation, shared memory has filesystem lifetime in some
-of those systems.
+[section:emulation 无共享内存对象的系统下的模拟支持]
+[*Boost.Interprocess] 提供了POSIX语义下的可移植共享内存。一些操作系统并不支 持POSIX规格的共享内存:
+*  Windows系统利用分页文件实现共享内存,但它的生命期与任一POSIX规格不同
+(请参阅[link interprocess.sharedmemorybetweenprocesses.sharedmemory.windows_shared_memory
+   原生Windows共享内存]段)。
+*  一些UNIX系统并非完全支持POSIX共享内在对象。
+在这些平台中,使用创建于临时目录里的"boost_interprocess"文件夹下的映射文件 来模拟共享内存。 +在Windows平台中,如果注册表中有"Common AppData"键,"boost_interprocess"文件 夹创建在其指定的目录中 +(XP系统一般是"C:\Documents and Settings\All Users\Application Data",Vista系统则是"C:\ProgramData")。 +至于没有该注册表键的Windows平台或Unix系统,共享内存创建于系统临时文件目录下 (类似于"/tmp")。

 [classref boost::interprocess::shared_memory_object shared_memory_object]
-provides a static `remove` function to remove a shared memory objects.
-This function [*can] fail if the shared memory objects does not exist or
-it's opened by another process. Note that this function is similar to the
-standard C `int remove(const char *path)` function. In UNIX systems,
-`shared_memory_object::remove` calls `shm_unlink`:
-*  The function will remove the name of the shared memory object
-named by the string pointed to by name.
-*  If one or more references to the shared memory object exist when
-is unlinked, the name will be removed before the function returns, but the
-removal of the memory object contents will be postponed until all open and
-map references to the shared memory object have been removed.
+这个函数有点类似于标准C函数中的`int remove(const char *path)`。在UNIX系统 里,
+*  该函数将移除由字符串指针指定的共享内存对象的名称。
+*  如果存在一个或多个共享内存对象的引用,函数返回前名称将被移除,

* Even if the object continues to exist after the last function call, reuse of
 the name will subsequently cause the creation of a
