The densities of the terrestrial planets average about 5 times the density of water, whereas the Jovian planets have densities that average only 1.5 times the density of water.

So, instead of having the periodic variation of water, or the periodic variation of air density here we're talking about an electric field.

不像水或者空气密度的,周期变化，我们这里,讨论的是电场。

The density of water molecules within the leaf is typically 60 times greater than the density of carbon dioxide in the air, and the diffusion rate of the water molecule is greater than that of the carbon-dioxide molecule.

During the dive, which takes up to four hours due to the high density of the water (it is filled with certain chemicals plus air pressure to simulate the circumstances found in space), the cosmonauts in training practice space walking -- and may lose a few kilos off their waist line in the strenuous process.

Mathilde is a rubble pile with a density very close to that of water.
