bounded by

基本解释

So, then I can choose my favorite surface bounded by C.
那么我可以选择一个被C界定的曲面。
The lifetime is most likely bounded by an expiration time, especially in a distributed environment where invalidating a token can be quite a challenge.
很可能通过一个过期时间来界定生存期，特别是在分布式环境中，要使一个令牌失效是非常困难的。
So, and similarly, if I take any other loop that avoids the origin, I can find, actually, a surface bounded by it that does not pass through the origin.
类似的，对于任何不经过原点的环路，都能找到一个以之为界的曲面,该曲面不经过原点。

Remember last time, I said that there's different kinds of complexity in our code, and I suggested for simple branching programs, the amount of time it takes to run that program is, in essence, bounded by the number of instructions, because you only execute each instruction at most once.
但是这里有个很重要的点,记得上节课，我提过在我们的代码中，有不同种类的复杂度，而且我还说了对于简单的分支程序,运行这种程序需要的总体时间,大体上，是和指令的数目相关的,因为每个指令只会被执行最多一次。
