Once it's cooled down below the critical temperature, the properties of the material change.

一旦温度降到界温度以下，材料的性质就发生变化。

For water, the critical temperature is about 647 Kelvin.

对，界温度 它等 373 秒。

They were afraid the critical temperature would be reached and it would set off a second explosion. That would have been a terrible tragedy.

他们担心抵达界温度而引发第二次爆炸 这造成严重的悲剧。

Above the critical temperature, you can increase the pressure as much as you want, but the gas will never condense into a liquid.

高界温度，我们可以压力增加为 我们想要，但气凝结成液。

The extra energy of the unbroken symmetry state would then be released and would reheat the universe to a temperature just below the critical temperature for symmetry between the forces.

未破缺的对称状态的额外能量被释放，并宇宙重新加热到刚好低力之间对称的界温度的温度。

Bosons, on the other hand, when they get below a critical temperature, they're like five-year-olds on a soccer field, so they don't have a concept of formation, they just bunch up together.

另一方面，当玻色子低界温度时，它们就像足球场上的五岁孩子，所以它们没有编队的概念，它们只是聚在一起。
