This is zero. So again, in the ideal liquid mixture case, their molecules aren't interacting.

这是零，又一次，在理想液体混合物的情况下，它们的分子没有相互作用。

If that's not zero, unlike the ideal case, now unlike before, where we just had entropy driving the mixture, now there's an energy of mixing.

如果那不是零，和理想的情况不同，和以前不同，以前我们只有熵来驱动混合，现在有混合能。

Of course, in the case of the ideal liquid mixture, there's no energetic interaction.

当然，在理想液体混合物的情况下，没有能量相互作用。

Then they measured the capacitance (the ability to hold an electric charge) of 4, 000 different positions to pinpoint the ideal mixture.

As Mr Bergan movingly recounts, Eisenstein developed a curious mixture of audacity and cunning, always pushing his films towards an ideal state which he must have known could never be realised, for political or economic reasons, yet managing to remain employed and to launch yet another project after the previous one had collapsed or been compromised or sabotaged.
