The temperature scale that turns out to be well—defined and ends up giving us the concept of an absolute zero is the ideal gas thermometer.

理想气体温标它有精确的定义，并能引出绝对零度的概念。

Their tool, the Bose-Einstein condensate, is a superchilled soup of matter that can be created only when the temperature is near absolute zero.

他们的工具——“Bose-Einstein”冷凝物是一种冰冷的汤质物，在接近绝对零度的温度下产生。

Unfortunately, the standard definition of a second relies on what the atom does at a temperature of absolute zero. Real clocks need to run at room temperature, where the shell of electrons puffs up.

遗憾的是，一秒钟的标准定义依赖于原子在绝对零度的条件，而实际的时钟需要在室温下运行，室温条件下电子壳层膨胀了。

So the concept of an absolute zero, a temperature below which you just can't go, that's directly out of the scheme here, this linear interpolation scheme with these two reference points.

这就是绝对零度，这样，从线性插值的图像出发，我们得到了绝对零度的概念，你永远无法达到,低于绝对零度的状态。

These atoms are cooled to a temperature of only a few billionths of a degree above absolute zero, the coldest possible temperature, at which all motion stops.

Their tool, the Bose-Einstein condensate, is a superchilled soup of matter that can be created only when the temperature is near absolute zero.

This slows down the movement, and hence the temperature, of its atoms to a fraction of a degree above absolute zero.
