在频谱感知中，我们使用能量检测的方法，发现半投票准则是最优的融合准则。

We focus on energy detection for spectrum sensing and find the optimal fusion rule which is the half-voting rule.

我们可以使用的所有能量都不会永远持续下去。

All the energy we could ever use won't last forever.

我们已经看到了所有其他机器人使用的方式，比一个人走路用的能量多得多。

All the other robots we have seen use way, way more energy than a human USES when a human walks.

Well, we can't guarantee with UV light we'll have enough energy to eject every single electron, so that's why when we use x-rays, they're higher energy, you can pretty much be guaranteed we're going to eject all of those electrons there.

好，我们不能保证紫外光有足够的能量,激发出每一个电子，所以我们要使用，X，射线，它的能量更高，你可以非常确定,我们可以激发出其中所有的电子。
