pz与pz重叠形成2个∏键)。在成键过程中，由于原子间的相互影响，同一原子中几个能量相近的不同类型的原子轨道（即波函数），可以进行线性组合，重新分配能量和确定空间方向，组成数目相等的新的原子轨道，这种轨道重新组合的过程称为杂化（hybridization），杂化后形成的新轨道称为杂化轨道（hybridorbital）。
And don't forget that hybridization is a construct invented to make it easier for us to visualize bonding but the experimental evidence is that it does not occur. So your idea that triplet CH2 has one electron in a p orbital and one in a sp2 orbital is not accurate. ...
The results indicate also that by means of hybridization changes the orbitals follow the nuclear displacements approximately 25% of the way in the case of the symmetric CH 2 deformation and slightly more in the case of the CH 2 rock.
+CH 2 =CH 2 is studied including the hybridization change of the reaction center. The interaction energy is devided into two parts. The first is a stabilization energy — the contribution due to the π -electron delocalization (including the hybridization effects). It is computed by the PPP ...
