嗯。。这个想像的还是有问题。。。
必须多人合作才能有双键出来 - -

“没有σ键哪有π键呀？没有猪皮哪有猪毛呀？”

强烈赞扬

很有才华！[s:63]

【我和你】σ键

我和你
头碰头
同住宇宙中
为成键
纳米行
相会在键轴
来吧
朋友
伸出电子云
我和你
头碰头
变成一家人

You and me, head to head, we are family,
For the bond, a nano-meter, meeting in bond axis.
Come together, share the electron cloud,
You and me, head to head, we are family.

谁来写个delta键
