Again, we're going to take the linear combination of those p atomic orbitals and make what are called pi or some more sigma molecular orbitals.

同样的，我们需要得到,原子p轨道的线性组合,然后组成我们所说的,π分子轨道或者sigma分子轨道。

So again, what we're talking about is the linear combination of atomic 2 p orbitals, and now we're talking about 2 p z.

同样，我们说的是,原子2p轨道的线性组合，现在我们我们说的是2pz。
