If I had taken as my interpolation scheme, my white curve here, I could go to infinity and have the equivalent of absolute zero being at infinity, minus infinity.

要注意，如果我们采用，像图中白线这样的插值方案的话,我就可以一直降温下去,相应的绝对零度点。

Something like this. That would be perfectly fine interpolation. All right, we choose to have a linear interpolation.

这种插值的方法也是完全可行的,好，现在我们决定使用，线性插值的方案。

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。

You can choose a linear interpolation or quadratic, but you've got to choose it.

你可以选择线性插值或抛物线型插值,但你总要做出选择。

Now there many ways I can connect these two points together. The simplest way is to draw a straight line. It's called the linear interpolation. My line is not so straight, right here. You could do a different kind of line.

最简单的办法是,像这样画一条直线,这叫线性插值,不过我的这条线画得不太直，你也可以用别的办法,比如一条抛物线。
