Like surface tension which turns water into a potentially deadly substance for insects.

如面张力，把变成对昆虫致命潜在陷阱。

That's what creates surface tension and it has a property called cohesion.

这就是产生面张力原因它有一种叫做内聚力特性。

How does your brain feel about calculating the surface tension of the domain walls?

那你大脑对于计算畴壁面张力怎么看？

Surfactants' ability to break surface tension makes them useful to humans as a wetting agent.

面活性剂打破面张力能力使它们作为湿润剂来说对人类是非常有用。

But buoyant objects don't rely on surface tension, so they continue surfing the meniscus.

但是有浮力物体不依赖于面张力，所以它们会继续在弯月面浮动。

A buoyant object will always repel something held up by surface tension's stretchy membrane.

一个有浮力物体总是会排斥由面张力弹性膜支撑东西。

They're too dense to be buoyant, they float because of surface tension.

它们密度太大以至于无法浮起来，它们漂浮是因为面张力。

And that's because surface tension takes over.

这是因为面张力出现了。

Water can't enter it because their hairs are too tiny to break its surface tension.

无法进入，因为它们毛发太细密了， 无法打破面张力。

It would quickly engulf you, its surface tension too hard for you to break and you'd drown.

它会很快把你吞进去，由于面张力太难打破，你会被淹死。

This defense mechanism relies on another property of surfactants — their ability to break the surface tension of water.

这种防御机制依赖于面活性剂另一种特性——打破面张力能力。

Instead, they gather into thick blobs of liquid around their eyes because the water surface tension holds tears together.

相反，眼泪在眼睛周围凝结成浓稠液体团，因为面张力把眼泪聚集在了一起。

Remember how I said spherical, blobby shapes minimize surface area thanks to surface tension?

还记得我说过球状滴形状由于面张力而使面积最小吗？

The chemical properties of soap lower the surface tension of water, so anything relying on surface tension to stay afloat will sink.

肥皂化学性质降低了面张力，因此任何依靠面张力保持漂浮东西都会下沉。

Surface tension happens because water molecules are more attracted to each other than the air around them.

面张力出现原因是因为分子彼此之间吸引力比它们周围空气对它们吸引力更大。

And so the insect carries its own outside lung around and can basically breathe underwater thanks to surface tension.

所以昆虫能到处带著自己外肺。并基本上能在下呼吸。一切受惠于面张力。

Or the Blue Dragon nudibranch, which floats upside down in the water using surface tension and camouflages with the water.

或者是蓝龙裸鳃鲨，它利用面张力倒挂在面上，并利用面伪装自己。

Well, now that you can focus again, what do you say we get back to surface tension of domain walls?

现在你注意力又能集中了，咱们可以回到畴壁面张力研究了吧？

Other aquatic insects like water treaders exploit surface tension, just like thumbtacks and paper clips.

其他生昆虫，如蟑螂，就像图钉和回形针一样利用面张力。

Because the surface tension is different in space.

因为空间中面张力是不同。
