如果您想要在应用程序将要支持的所有体系结构上保持通用的起始地址，那么在确定那个地址之前必须考虑所有的体系结构。

You have to consider all architectures before deciding on the addresses if you want to keep the starting addresses common for all the architectures that are going to be supported by the application.

缺点是，32位的程序必须认识这种分段体系结构，才能充分利用32位地址空间。

Of the disadvantages, a 32-bit program must be cognizant of the segmented architecture to take full advantage of the 32-bit address space.

在这种体系结构中，对于所有平台，每个进程的地址空间都是2的64次方，或者18,446,744,073 GB。

With this architecture, the address space of each process is 2 to the power of 64, or 18,446,744,073 GB, on all platforms.
