These particles have very high ratio surface area, which make it consolidated to form glass easily.

这种粉末具有很高的比表面积，因而很容易烧结成玻璃。

The result shows:The reaction time for using of the oxide was shorter and the ratio surface of the super-thin oxide was smaller.

结果表明：利用微波加热技术制备的超细氧化物所需反应溶液的浓度低、所用的反应时间短、比表面积大。

The results showed that the biodegradability of the films was strongly correlated with starch content of the films and impacted by ratio surface area of the films.

试验结果表明，膜的生物降解性与膜中的淀粉含量正相关，并受膜比面积大小的影响。

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.

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

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.
