And 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.

比如理想气体温标,它有精确的定义,并能引出绝对零度的概念,今天我们就先来谈谈它。

All right, so now we have the makings of a good thermometer and a good temperature scale.

这一常数只决定于温度,于是我们现在,可以定义一个理想的温度计和温标了。

The lowest possible temperature in the Celsius scale is minus 273.15 degrees Celsius. So that begs the notion of re-referencing our reference point, of changing our reference points.

在摄氏温标中,绝对零度是-273。15摄氏度5,这样，我们需要重新定义参考点,将零度的参考点取在绝对零度处，而不是0摄氏度处。
