So instead of v bar, we write p v bar minus b, equal r t.
现在考虑,这些气体分子之间。
Now you have to know from elementary calculus that v times dv/dt is really d by dt of v square over 2.
根据初等微积分知识你们得知道,v乘以dv/dt其实就是d/2)/dt
And our job is to find out what is the mathematical description of this path, this line in p-V's case that connects these two point.
我们的任务,就是找出,描述这条曲线的方程。
In the case of France again, they are the work of a brilliant military engineer called Vauban, v-a-u-b-a-n.
例如法国,在佩皮尼昂 里尔 蒙梅迪等地方,这样的要塞城镇随处可见
And,so,Henri V could capitalize on that because there were lots of people that would be very happy to see him come back because of their belief.

How many of you have seen Henry V in the Laurence Olivier version 1945?
有多少人看过一九四五年版,劳伦斯·奥立佛执导的《亨利五世》
ArgV You can think of this variable Arg V as literally an array a sequence of chunks of memory that literally are back to back to back in memory, and when you say bracket zero, by convention, you are referring to the variables stored here.
你可以想象这个变量,按顺序排列的一块块内存,依次地在内存中紧邻着的,当你指明,按照惯例,涉及,存储的变量在这里。
Okay. So that's the "Duke of Earl" progression: the basic I,VI,IV,V,I.
好,这就是Duke,of,Earl这首歌的和弦进行,I,VI,IV,V,I级。
And if we talk about electrons or photoelectrons, again we can describe it in terms of energy, we can talk about velocity, and from there, of course, you can figure out the energy from 1/2 m v squared, and actually we can also describe the electron in terms of wavelength.
如果我们谈论电子或者光电子,我们又可以从能量的角度来描述它,我们可讨论速率,从那里,当然,你可以计算1/2,m,v2得出能量值,而且事实上我们也可以,从波长的角度来描述电子。
We'll get an expression in which there is no t; t has been banished in favor of v.
我们现在得到了一个不含t的表达式,t被v替换掉了
So I can make a quantity that I'll call V bar, which is the molar volume, the volume of one mole of a component in my system, and that becomes an intensive quantity.
所以我可以定义,一个叫做一横的量,这是摩尔体积系统中,一摩尔某种组分的体积,它就变成了。
This is his picture of Charles V at a battle in Germany in 1648.
这是一张查理五世,在1648年德国战争中的画
Get out of your mind Henry V, forget the Battle of Agincourt.
忘掉亨利五世,1415年英王亨利五世于法国北部阿金库尔村以弓箭手重创兵力数倍于己的法军
And if I draw a diagram on a T-V diagram of T-V V1 I'm starting with some V1 here.
画出过程的,图,what,I’m,doing,here,初态是。
When a particle moves in a circle, it has an acceleration towards the center of this size, v^2 over R.
当一个质点在圆周上运动时,它有一个指向圆心的加速度,v^2 / R
As p goes to zero of p times v bar.
适用于任何气体。
