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

It's a very common thing to get, the triple point from this.

从这里得到三相点是非常常见的。

youdao

The triple point temperature, triple point pressure.

这是三相点温度，这是三相点气压。

youdao

So this unique temperature and unique pressure defines a triple point everywhere, and that's a great reference point.

这样，无论在何处,三相点都具有相同的温度和压强,十分适合来作参考点。

So the triple point is liquid solid, gas, all in equilibrium.

气态，固态，三相平衡,你可能会想。

So the partial pressure or the pressure by which you have this triple point, happens to be 6.1 times 10 to the minus 3 bar.

而要小得多,事实上，水的三相点时的压强是6。1毫巴。
