从计算机大小的角度来看，虚拟内存是

Virtual memory from a computer size perspective is

[一种制作程序的方式] 具有大范围的连续性 地址；但实际上是零件 当前正在使用的是分散的 在RAM周围，非活动部分是 保存在磁盘文件中. (维基百科)

[a way to make the program] think it has a large range of contiguous addresses; but in reality the parts it is currently using are scattered around RAM, and the inactive parts are saved in a disk file. (Wikipedia)

我会将Windows任务管理器中的VM大小解释为可寻址虚拟内存总空间或该进程当前在虚拟内存空间中使用的内存量.

I would interpret VM Size in the Windows Task manager as either the total addressable virtual memory space or the amount of memory the process is currently using in the virtual memory space.

但是在许多情况下，在任务管理器中，WM大小小于内存使用量"，后者应为该进程正在使用的RAM数量.因此，我想WM尺寸还有其他含义吗?

But in the Task Manager the WM Size is in many cases less than Mem Usage, which should be amount of RAM the process is using. Therefor I guess that WM Size means something else?

推荐答案

这是此进程分配的所有私有(非共享)字节的总数，无论当前是否在物理内存中.

It's the total of all private (not shared) bytes allocated by this process, whether currently in physical memory or not.

对于这样的开发人员来说，我建议安装 SysInternals Process Explorer 并使用它代替默认的任务管理器.此值在其中称为专用字节".

For a developer watching process state like this I would recommend to install SysInternals Process Explorer and to use it instead of the default Task Manager. This value is called "Private Bytes" in it.
