And when we take the wave function and square it, that's going to be equal to the probability density of finding an electron at some point in your atom.

当我们把波函数平方时，就等于在某处,找到一个电子的概率密度。

The important point here is it's not just a probability, it's a density, so we know that it's a probability divided by volume.

它不是概率,而是概率密度，所以我们知道，它是密，除以体积，我们。

Proponents point to the enormous energy density of the fuel (the amount of energy contained per unit).

FORBES: The Future of Nuclear Power in the United States

That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation.

FORBES: As SOPA Looms, John Perry Barlow On 'The Right To Know'

While proponents of deregulation point to lower fares between high density hubs, these bargains are subsidised by exorbitantly high fares for flights between the thousands of smaller cities across the country.
