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。

Last time we reach the third law which is telling us that we can't quite get to zero degrees Kelvin .but that as the temperature approaches zero degrees Kelvin, the absolute entropy of a pure substance in perfect crystalline form is zero.

上次课我们得到了热力学第三定律,这个定律告诉我们我们无法,达到0K的温度,但是在我们接近绝对零度的过程中，以完美晶体形式存在的纯物质的绝对熵,也趋向于零。

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.
