If I now hybridize these, if I take these and I make four symmetric, now, these are just the sp3 orbitals.

如果我将他们杂化，然后形成4个对称的轨道，这就是sp3轨道。

This bond is polar, but again, as I alluded to earlier, because the carbon is centered in the tetrahedron, because of the sp3 hybridization, the molecule itself is symmetric and nonpolar.

这个键是非极性的，但是，我们断言过早，因为C是中心原子，由于sp3杂化，这个分子本身是非极性的且对称的。

All right, so in terms of s p 3 hybrid orbitals, let's combine all four together on one axis, because this is what's going to happen in an s p 3 carbon atom.

对于sp3杂化轨道，让我们把4个结合起来，因为这是sp3碳原子中发生的情况。
