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。
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。
Then if I change to the triple point, where the number of phases is three, then the number of degrees of freedom 2 is one minus three is minus two, two plus two is zero.
如果考虑三相点，这里有三个相，那么自由度的数目，为1减去3得负，再加上2等于零。
