可以在概念上将哈希表认为是一系列的 bucket，每个 bucket 所拥有的地址是通过应用哈希函数从键值导出的。

You can think of a hash table conceptually as a series of buckets, each with an address that is derived form the key value by applying the hash function.

子进程的进程号（PID）将成为这个散列的关键字，而其键值就是该子进程正在处理的相对应的主机地址。

The keys of this hash will be the child process ID (PID), and the value will be the corresponding host that the child is processing.
