And that buoyant object did the opposite, it floated to the middle.

而那个有的物体则反，它漂到l了中间。

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

但是有的物体不依赖于表，所以它们会继续在月动。

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

一个有的物体总是会排斥由表弹性膜支撑的东西。

It's buoyant, it weighs less than the milk it displaces.

它是有的，它的重量比它排开的牛奶轻。

A buoyant object will always be pushed up the liquid to the highest point on a meniscus.

有的物体总是会被向上推到月的最高点。

Manatees fart to maintain the right buoyancy in water.

海牛放屁是为了在水中保持适当的。

Floating in space is similar to floating in water, so astronauts practise their spacewalk in swimming pools.

在太空中受到的和在水中受到的同，所以宇航员在泳池中练习太空行走。

Any such churning is overwhelmed by the extra buoyancy of the warmer surface layers.

海洋的任何搅动都被表层海水所增加的给掩盖了。

That's because the upward buoyant force is always stronger than the downward force of gravity.

那是因为向上的总是强于向下的重。

Their size gives them increased buoyancy and musculature to be great swimmers.

它们的体型增加了它们的的和肌肉组织，使得它们成为了优秀的游泳运动员。

So as you travel deeper, the buoyancy force from the metallic hydrogen counteracts gravity's downward pull.

所以当你下降得更深，来自金属氢的，抵消掉向下的重。

Wang said she was most impressed by the buoyancy experiment Wang Yaping conducted.

王亚平的实验让王亚萍印象最深。

Tiny hairs on their legs trap air bubbles and increase their buoyancy.

它们腿上的细毛捕获气泡并增加它们的。

And I argued if one balloon provides some unit of lift, why wouldn't we be able to scale that?

我想说，如果每个气球都能提供一定的，那我们多用些气球不就行了吗？

If the length or diameter of the bamboo is not long enough, it will not be buoyant enough to float.

如果竹子的长度或者直径不够，便不会产生足够的。

The way we practise spacewalk is in water. Water gives us the neutral buoyancy that we need.

我们训练太空行走是在水中进行的。水能给我们提供我们需要的中性。

Their presence lowers the magma's density, and increases the buoyant force pushing upward through the crust.

它们的存在降低了岩浆的密度，并增加了向上推动地壳的。

After all, penguins aren't trying to stay up in the air; they're fighting against the buoyancy of seawater.

毕竟， 企鹅并不想在空中停留；他们在对抗海水的。

The liquid in turn exerts an upward buoyant force equal to the weight of the fluid that's been displaced.

液体反过来施加向上的，等于被置换的流体的重量。

So it's going to be modular, it's going to be buoyant, it's going to be designed to resist a tropical storm.

所以它将是模块化的， 它是有的，它的设计是为了抵御热带风暴。
