To remind you of something we learned from biology: the surface area ratio increases when the volume of an object decreases.

要是你还记得的话，上生物课时我们学过：一件物件的表面面积比率，随著物件体积减少而增加。

The noble metal sulphide particles are monodispersed on the active carbon particles and the surface area ratio of noble metal sulphide particles to active carbon particles is at least 0.20.

What's so great about the dome is that it does exactly what Bucky wanted; that is, it has the highest ratio of enclosed area to external surface.

圆屋顶额伟大之处在于它封闭区到外部表面的比例最高，那正是巴基想要的效果。

The family of these materials includes much-touted, carbon-based members such as graphene and nanotubes, and are notable in part for their surface area-to-weight ratio.

But as an object gets smaller, the ratio between its surface area and its volume rises.

The result, they claim in a paper that will appear this month in the Journal of Physical Chemistry, is a nanofibre material with an extremely high ratio of surface-area to volume.
