And if we go ahead and square that, then what we get is a probability density, and specifically it's the probability of finding an electron in a certain small defined volume away from the nucleus.

我们得到的是，一个概率密度，它是，在核子周围，某个很小的,特定区域,找到电子的概率,所以它是概率密度。

Double your vegetable intake and reduce fat -- Both of these changes will significantly decrease the calorie density of your diet without decreasing the volume of food that you consume.

CNN: How can I maintain my energy level for sports while on a diet?

But accurately working out Mathilde's volume (necessary because density is the ratio of mass to volume) was harder.

ECONOMIST: Asteroids

Power density refers to the energy flow that can be harnessed from a given unit of volume, area or mass.
