He urged revival of the slave-trade in the late 1850s, and he developed a theory of what he called warranteeism--w-a-r-r-a-n-t-e-e-I-s-m.

他促成了十八世纪五十年代后期,奴隶交易的复苏,还自己发明了一套理论,名为抵押品主义

I've been using the blackboard a little ad hoc here, but suppose I neaten things up here now and present this rectangle is let's say R RAM, the memory inside of your computer.

我在这里特别地使用这块黑板，假如我整理这些东西，把它们呈现,这个长方形，假如说就是内存，你电脑的内存。

It's true for any gas, and if I remove this limit here, r t is equal to p v bar, I'm going to call that an ideal gas.

这样的气体被称作理想气体,这就是理想气体的性质，理想气体的涵义是什么？

but I think it's motivational, and so I said, are you sure that J.R. Hicks invented the term "forward rate"?

但我觉得这很有趣,我问他,你能肯定,J·R·希克斯是"远期利率"的提出者吗

I'm going to just put that in, and it's the cosine of the number times i plus sine of the number times j times R.

我要在式子加入这个量,这个式子就等于这个值的余弦乘以 i,加上这个值的正弦乘以 j 再乘以常数 R

But instead in this chemistry course, I will just tell you the solutions to differential equations. And what we can do is we can start with some initial value of r, and here I write r being ten angstroms. That's a good approximation when we're talking about atoms because that's about the size of and atom.

但在这个课里，我会直接，告诉你们微分方程的解,我们可以给距离r一个初始值,我这里把r取10埃,当我们讨论原子时,这是一个很好的近似,因为原子的尺寸。

I'm going to call it r. It's going to be the gas constant, and now I have r times t is equal to the limit, p goes to zero of p r.

如果去掉p趋于0的条件,在有限压强下都,保持RT=pV的关系。

That's what I meant. This is called R.

这就是我说的 R

If you want to write it as a vector equation, you want to write it as v square over r minus-- I want to say that it's pointing in the direction toward the center.

如果要写出矢量方程,就应该写成 -v^2 / r,也就是说,方向就向圆心

If you are describing a particle with location R, the vector we use typically to locate a particle, R then R is just i times x + j times y, because you all know that's x and that's y.

如果你要描述一个位移为 R 的质点,这个矢量一般用表示质点 R 的位移,R 可表示为 i ? x + j ? y,显然你们都知道这段是 x,那段是 y

p1V1/R That p2 V2 over R, and then I have p1 V1 over R, the R's cancel out.

就是p2V2/R除以，两个R消掉了。
