Natural weathering rates are limited by, among other factors, the exposed surface area of chemically reactive rock.
自然风化的速度受进行化学反应岩石的接触表面积等因素限制。
That can be used as a proxy for phytoplankton population in a given area, since the tiny organisms live close to the ocean's surface, where they are exposed to sunlight they use to produce energy.
海水的清晰度可被用作衡量在特定水域的浮游植物数量的指标，因为这些微生物生活在海洋表面，在那里它们可以得到它们用之产生能量的阳光。
They're crisper and thinner than regular fries, which means that they're exposed to greater heat per surface area, killing pathogens and reducing water content.
麦当劳的薯条比一般的更脆也更薄，说明他们表面过油的时间也更长，杀灭了细菌原体也降低了水分含量。

And so desert plants have evolved ways to stay hydrated, including sporting tiny leaves to reduce the surface area exposed to the sun's water-zapping rays.
因此这些沙漠植物进化出保持水分的各种方式，包括长着极其细小的叶子以缩减暴露在炎炎烈日中的面积。
The advantage of that, he says, is that the small particles would have much more surface area exposed to sunlight and the water, allowing them to harness the sun's energy more efficiently.
这个的优势，他说，在于小粒子在阳光下和水中会有更大的表面积，就能更充分的吸收阳光。
Cleaning of the surface is in the form of bubble formation on the part that vaporizes the chemical in order to react the oxidizer in the vapor state to the exposed surface at the bubble growth area.
表面的清洗为在零件上形成气泡的形式，其使化学品蒸发以在气泡形成区域将处于蒸气状态的氧化剂与暴露的表面反应。
