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。

So this is very similar to what we saw i n terms of sigma orbitals and pi orbitals.

这和我们在sigma轨道,和π轨道中看到的很像。
