蛋白物的生存取决于骨骼形成化石的方式。
The survival of the proteins depends on the way in which bones are fossilized.
鼻部的组织和软骨结构太软,无法形成化石。
The tissue and cartilage of a nose are too soft to fossilize.
在这重要的一亿年的周期内缺乏化石(记录),关于这一点,有一种解释是早期的动物是软体动物,所以它们无法形成化石。
One interpretation regarding the absence of fossils during this important 100-million-year period is that early animals were soft bodied and simply did not fossilize.
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。
We can still hybridize all these orbitals, however, so we can still form four hybrid orbitals, which are again, 2 s p 3 hybrid orbitals.
但我们仍然可以杂化这些轨道,所以我们还是可以形成4个杂化轨道,同样的,是2sp3杂化轨道。
So, this forms a tetrahedron, which forms the sp3 hybrid orbitals.
这就形成了一个四面体,它是由sp3杂化轨道形成的。
