这是汽化线，有时汽化和液化曲线没有完全分开，因为某些原因，这两条线会在某个点相交，非理想情况。

And the bubble line. Sometimes, instead of having a nice separation between the bubble and the dew line, there's a special point which for some reason those two curves meet. Non-ideality.

我在这个点，保持溶液混合物，然后进行汽化，在这里读出气相的成分比例。

I'm on this point here, I keep my solution, my mixture. I make a gas, I read off the composition of the gas phase here.

大体标本上测量汽化腔的大小，观察不同能量级、不同时相点及不同分组的汽化腔大小差异。

The sizes of the boiloff cavity at the gross specimens were observed and the differences of the sizes were compared among different energies, different times and different groups.
