This one turns out to be the heat capacity, and this one turns out to be something that we measure in the Joule-free expansion.
其实,这就是热容,这是焦耳自由膨胀实验中,我们要测量的物理量。
And for any of the other compounds. So in other words, by defining that reference state, we can then figure out or measure heats of formation of a vast number of compounds.
对吧?对于任何其他的,化合物也是一样,所以换句话讲,定义了这个参考状态,我们就能算出或测量许多。
It's a measure of Milton's ambition and his intellectual courage that enables him to set out to justify a God who can inflict upon his creatures such a seemingly arbitrary act of licensing.
就是弥尔顿的雄心和他智慧的勇气,让他去证实上帝是能强加给他创造的世界,这样看起来专横的控制的行为。
So there it's--I'm simply taking the Cole Porter piece and throwing in an extra beat in each measure an unstressed beat in each measure and it works out pretty well.
我只是简单的把科尔·波特的作品,在其每小节中,加了一拍,在其每小节中,加了一个非强拍,看起来效果还很不错
It turns out the electrical potential or electricity that you can measure on the surface of the body reflects things that are happening deeper inside like the beating of your heart.
人们已经证明在体表测量得到的电势能,或者电信号,能够表征,像心跳这样,身体较深处的变化
But if we could statistically control for every other variable, all I'd need to do is measure the distance from your door to everybody else's door on campus and I could chart out who's going to fall in love with whom on the Yale campus.
如果我们能精确地控制其他可变因素,那么只需要测测距离,你宿舍门到其他宿舍门的距离,我就能够计算出,校园里谁爱上了谁。
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。
This is why people right tables and tables of H delta H's. Why you have delta H's from all these reactions, because this is basically the heat and the heat is something we can measure, we can control. We can figure out how much heat is going in and out of something.
这就是为什么人们一再提出ΔH的原因,为什么在所有的反应中你都能看到Δ,因为它就是热量,而且热量,是一种我们可以测量并且控制的东西,我们可以测量出有多少热量,从一些东西里面放出或被吸收。
