So basically if we think of buckets and pipes, that's a very thin pipe connecting the bucket for A and B, B so we drip from A to B, C then we have this very fat pipe connecting B and C.

大体上如果我们想象桶和管子，连接A桶和B桶的管子很细，所以液体从A滴入，然后我们有很粗的管子连接B和。

The optimizer has been able to do algebraic simplification on a+a, instead generating 2*a, and on (c*b)*12 + c*b, instead generating (c*b)*13.

该编译器可以对a+a进行代数简化，即改为生成2*a，也可以对 (c*b)*12 + c*b 进行代数简化，即改为生成 (c*b)*13。

If a user's PATH is set to a: B: c: d, the shell first attempts to find the command in directory A. If it isn't found there, the shell moves on to look in directory B and so on.

如果用户的PATH被设置为A：B：C：D，那么shell将首先尝试在目录a中查找命令。
