The bigger the animal is, the lower its surface-to-volume ratio; for every ounce of body mass, there is proportionately less surface through which heat can escape.
动物体型越大，其体表体积比越低；躯体每增加一盎司的重量，所能散发热量的表面就成比例减少。

Second, the high surface-to-volume ratios of such bodies promote heat loss, so they cool quickly between successive impacts.
第二，这类天体的表面积对体积比值高，促使散热更快，因此在各次撞击之间会快速冷却。

Semiconductor nanoparticles possess many unique optical properties, high surface-to-volume ratio and other properties related to their nanometer dimension.
