The sharp drop in oil prices in recent weeks may reduce this differential, but could easily be reversed by supply disruption or a harsh winter.

近期原油的大幅下跌也许能减少两者之间的差距，不过原油供应的中断或是严冬都很容易再度扩大这个差距。

OK, and now we return to this differential.

好，让我们回到这个微分式。

We can measure the heat capacity at constant volume, and now we have another term, and if we can figure out how to measure it, we'll have a complete form for this differential du which will enable us to calculate du for any process.

我们能够测量恒定体积下的热容，这里我们有另一项，如果能够知道怎么测量它，问我们就有了这个完整的微分式,就能够对任何过程计算。

So, let's say we start off at the distance being ten angstroms. We can plug that into this differential equation that we'll have and solve it and what we find out is that r actually goes to zero at a time that's equal to 10 to the negative 10 seconds.

也就大约是这么多,所以我们取初始值10埃,我们把它代入到,这个微分方程解它,可以发现，r在10的,负10次方秒内就衰减到零了。
