任何情况下工不需要计算时间，但是功率需要。

In any case work does not include time, but power does.

在这种情况下，激进的编译器可能认为它根本不需要计算result。

In this case, an aggressive compiler might conclude that it does not need to compute result at all.

因为不需要计算傅立叶逆变换，因此两尺度序列更易于求得。

The centrosysmmetric B-spline wavelets have simple expressions and the two-scale sequences are easily obtained.

And as long as that smaller computation reduces to another smaller computation, eventually I ought to get to the place where I'm down in that base case.

如果我不属于基础事件,那么我需要把它简化为更简单的计算，随着计算的不断简化,最终我能分解成基础事件。

Now remember, we went through before how it's a state function but to calculate it, you'd need to find a reversible path, along which you can figure this out.

请记住，我们不需要知道它是怎样的一个态函数,只计算就可以了，你需要找到一条可逆路径，沿着这条路径就能算得这个结果。

And if you're going from Boston to someplace else where New York just happens to be on the way, it doesn't have to recompute that part of it.

如果你是从波士顿到其他地方,而碰巧路过纽约你就不需要，重新计算从波士顿到纽约这段路了。
