And if you have rough candy with a high ratio of surface area to volume, then there's more places for the bubbles to go.

如果你粗燥的硬糖具有很大的表面积，那么泡泡们就有更多的地方可以去了。

This, in turn, means clever engineering can increase the surface area (and thus the storage capacity) without increasing the volume.

这样，就意味着巧妙的工程学能够在电压不变的情况下通过增加电极间表面积以提高电荷储备。

So if we want to talk about the volume of that, we just talk about the surface area, which is 4 pi r squared, and we multiply that by the thickness d r.

如果我们要讨论它的体积，我们要用的是表面面积，也就是4πr的平方，乘以厚度dr

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

ECONOMIST: Small wonders

Self-seeding may explain why large tumors tend to grow (in percentage terms) more slowly than small tumors: It could be that growth is a function of surface area rather than volume.

FORBES: Magazine Article

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.
