-
To change a reference point from this point here being zero instead of this point here being zero.
这样就得到了,开尔文温标。
-
Because we can take our interpolation here our linear interpolation the slope of this line.
用开尔文,而不是摄氏度作单位。
-
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。
-
And we had the similar statement by Kelvin about the heat engine that required that some heat gets dumped into a cold reservoir in the process of converting the heat from the hot reservoir into work.
相同的陈述,同样的有开尔文表述：,把热量完全从高温热源,转移至低温热源的过程中,必然有功的输出。
-
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。
-
Let's draw it in degrees Kelvin, instead of in degrees Celsius.
来重画一下这幅图，现在温度的单位是开尔文。
-
And then you would get the Kelvin scale.
这就是开尔文温标。
-
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。
