It is important to set this limit so the stack and Shared memory address space do not collide with each other.

设置这个限制，使堆栈和共享内存地址空间不会相互冲突，这一点很重要。

However, if two or more processes want to communicate using Shared memory, they need to have the same address space, thus limiting the addresses they can utilize.

然而，如果两个或更多进程要使用共享内存进行通信，那么它们需要有相同的地址空间，从而限制了它们所能使用的地址。

However, a Shared memory segment cannot be "split" across quadrants and be guaranteed a contiguous address space.

但是，共享内存段不能跨象限“拆分”，而应该保证是一个连续的地址空间。
