All right, so you can't get perfect efficiency, 0 but at least if you were able to go to zero degrees Kelvin, then you'd be all set.

好吧，你得不到完美的效率，但至少如果能把温度降到,那你就万事俱备了。

If you could get to zero degrees Kelvin, you'd get perfect efficiency, 0 but you can't get to zero degrees Kelvin, you can't. Even if you have an infinite amount of resources, you can't get there.

如果能达到，你就能获得完美的效率，但你得不到，得不到，即使你有无穷多的资源,你也做不到。

So, it turns out that we have zero nodes that we're dealing with when we're talking about a 3 d orbital.

所以结果是,３ｄ轨道没有节点。

That's going to presumably be given--mathematically if we gave it a number, we'd slap a zero on that.

如果用数学解释,给它一个数字，给它一个零。

5 So similarly would there be the number 65 next to this then the corresponding number for V-I-D and then there's generally a special character at the end that looks like a zero that says end of string here.

同样，A就是,接着再填上V-I-D对应的ASCII码,在最后还有添上一个特殊的字符,有点像0，代表这是该字符串结束。

I can write this as d less than zero.

我可以把这个写成的d小于零。

But in sigma orbitals, you have no nodal planes along the bond axis, so if we had a nodal plane here, we'd see an area where the wave function was equal to zero.

但在sigma轨道里，沿着轴向是没有节点平面的，如果我们有个节点，我们就会看到某个地方波函数等于0。

We can look at the 2 p, which should have one radial node, and we just figured it out for the, excuse me, 3d for the 3 p has one radial node, and for the 3 d here, we should have zero radial nodes, we just calculated that.

我们看2p，它有一个节点，我们已经知道对于，不好意思，是3p有一个节点，对于，它应该没有径向节点，我们刚刚算过这个。
