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。
In the pumping process, if water levels continue to decline, we should pay attention not to let the exposed surface of the water running submersible pump.
在抽水过程中，若水位不断下降，要注意不要让潜水电泵露出水面运行。
