But keep in mind sigma orbitals have no nodal planes along the bond axis.

但记住sigma轨道沿着，键轴方向是没有节点的。

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。

And a sigma bond forms any time you have two orbitals coming together and interacting on that internuclear axis.

当你把两个轨道合在一起，并在核间轴上有相互作用时，就形成了sigma键。

Any time two orbitals come straight on together in that internuclear axis, you're going to have a sigma bond.

任何时候两个轨道，在核间轴上直接到一起，你就能得到sigma键。

First of all, this is the two s orbitals in hydrogen, 1s plus 1s smearing to give us this sigma molecular orbital.

首先，这是氢气中的两个s轨道，1s与1s轨道重叠，产生sigma分子轨道。
