All right, next time we're going to talk about a much better scale, which is the ideal gas thermometer and how we get to the Kelvin scale.

好，下次我们,会讲一种好得多的温标，关于理想气体温度计,和开氏温标的导出。

And so now, instead of using these reference points for the Kelvin scale, we use the absolute zero, which isn't going to care what the pressure is.

就像理想气体温标,与气体的种类无关一样，具有普适性，在开尔文温标中。

So, this temperature, this absolute zero here, which is absolute zero on the Kelvin scale.

在负无穷处，现在把绝对零度定义为，开尔文温标中的0度。

The reference points are water freezing or boiling, and the interpolation is linear and then that morphed into the Kelvin scale as we're going to see later.

参考点是水的冰点和沸点,插值是线性的,随后它被发展成为开氏温标,我们之后会看到。

And then you would get the Kelvin scale.

这就是开尔文温标。

And so redefining then the temperature scale to the Kelvin scale, where t in degrees Kelvin is equal to t in degree Celsius, plus 273.15.

以K为单位的温度,是以℃为单位的温度,加上273。15度。

We have an interpolation scheme between zero and 273.16 with two values for this quantity, and we have a linear interpolation that defines our temperature scale, our Kelvin temperature scale.

的两个值做线性插值,就得到了开尔文温标,直线的斜率等于水的三相点,也就是这一点处的f的值,再除以273。16，这是这条直线的斜率，这个量，f在三相点处的值。
