这是反键分子轨道，我们有了成键，现在我们讨论反键。
So if we name this orbital, this is an anti-bonding molecular orbital So we had bonding and now we're talking about anti-bonding.
这里的这个，因为处在一个较高的能级，被叫做反键分子轨道能级。
And this one here, because it is at a higher energy is called antibonding molecular orbital.
我将给分子轨道加上标，这个上标，表示反键轨道，有一个星号。
And I am going to superscript it molecular orbital, and this upper one, to indicate that it's antibonding, has the asterisk.
特别的，我们把它们和，分子轨道相联系起来，我们说它们可以成为，成键轨道或者反键轨道。
So specifically, what we do associate them instead is within molecular orbitals, and what we say is that they can be either in bonding or anti-bonding orbitals.
这是sigma星，来自于1s的反键轨道，它是一个分子轨道。
This is sigma star with the antibonding orbital that came from 1s, and it is a molecular orbital.
本文对分子轨道理论教学中关于对称性匹配原则，最大重叠原则， 分子轨道符号及反键效应等几个问题进行了讨论。
The present author discusses the symmetricalmatching principle, the maximum overlapping principle, the molecule orbitalsymbols and the anti-bond effect in the teaching of the molecule orbital theory.
通过CO分子接近表面时各分子轨道能量本征值的变化，讨论了各轨道的成键、反键特征。
The bonding and antibonding character for the CO valence level have also been studied by analysis of the variations of the molecular eigenvalues when the CO molecule approaches the surface.
今天我们先来，讨论两种分子轨道，我们要讨论成键和反键轨道。
So, we'll start today talking about the two kinds of molecular orbitals, we can talk about bonding or anti-bonding orbitals.
