The triple point temperature, triple point pressure.

这是三相点温度，这是三相点气压。

youdao

So our usual phase diagram here with temperature on this axis here and pressure on this axis here, and we've got our triple point sitting here.

我们通常的相图是这样，这个轴是温度轴，这个轴是压强轴，这里是三相点。

youdao

A unit of absolute temperature equal to1/273.16 of the absolute temperature of the triple point of water. This unit is equal to one Celsius degree.

开绝对温度单位，等于水的三态点绝对温度的1／273。16。这个单位等于一摄氏度。

youdao

And the triple point of water is 16K that temperature and pressure - there's a unique temperature and pressure where water exists in equilibrium between the liquid phase, the vapor phase, and the solid phase.

与水的三相点,我们定义它为273。,水的三相点,是一个特定的温度和压强,可以使水的液态，气态和固态三相共同达到平衡，三相点是液态。
