这种海绵状组织是形成蛋壳的钙质来源。

This spongy tissue serves as a source of calcium for eggshell formation.

巢里的那些恐龙可能是成年雄性，不会需要用来制造蛋壳的钙。

Those dinosaurs on the nests were probably adult males who wouldn't have needed calcium for making eggshells.

这种名叫OC-17的蛋白质能够加速蛋壳的形成。

The protein, called ovocledidin-17 (OC-17), speeds up the development of the shell.

But still, when we're talking about the radial probability distribution, what we actually want to think about is what's the probability of finding the electron in that shell?

但当我们讲到径向概率分布时,我们想做的是考虑，在某一个壳层里,找到电子的概率,就把它想成是蛋壳？

So if you think of a shell, you can actually just think of an egg shell, that's probably the easiest way to think of it, where the yolk, if you really maybe make it a lot smaller might be the nucleus.

可以把它想成，个蛋壳，这也许是，最简单的思考办法,蛋黄如果，缩小非常多倍的话,就可以想象成核子。
