This depends on the path. It tells you right here the path is constant pressure. These don't depend on the path, right. V doesn't care how you v get there. u doesn't care how you get there.
这由变化的具体路径决定,这个小脚标表明过程是恒压的,这些量都与具体路径无关,即不管是通过什么路径使得体积变化为Δ
How is the real estate market doing in the U.S. right now?
美国现在的房地产市场怎么样?
The U.S.Bill of Rights, specifically the Second Amendment, guarantees Americans the right to keep and bear arms.

And now we're almost done, except what we H really want is delta H and not delta U, right.
我们差不多已经完成了,除了我们实际上想要的是Δ

60 kilobits of memory. I mean, your flash cards have more than that, right?
是的160K,你们现在的U盘,都比这个容量大吧?
"This is a duty and a right." The Goldstone Report endorsed by the U.N.
VOA: standard.2009.10.18
Now, you know with constant volume, H now it's not going to be delta H that's U straightforward to measure, it's going to be dealt u, all right.
好,现在你们知道在体积恒定的条件下,我们得到的不是Δ,我们直接测量到的是Δ,好,但这基本上也是一样的。
I still think everything is not perfect in our mortgage situation in the U.S., and the dollar is rallying, but that's a bad thing right now.
VOA: standard.2010.05.21
Well, all right, delta u is equal to zero for that.
好吧,绝热过程中。
Last year, the court ruled the 2nd amendment to the U.S.Constitution's protects the right of an individual citizen to own a handgun in the District of Columbia, a federally governed enclave.
VOA: standard.2009.10.01
So delta u B is Cv times T2 minus T1, right.
是Cv乘以,对吧?
Morrell said the review does not mean that the counterinsurgency approach is over, but rather that U.S.officials want to make sure their strategy is right before committing significant numbers of additional troops.
VOA: standard.2009.09.23
It makes sense, right, because you know we got less work out and delta u is the same right, so it must be that less heat got transferred.
这是显而易见的,因为输出的功更少,且Δu相等,所以需要的热量更少。
The high court ruling says the right to have a handgun for self defense is a fundamental right under the Second Amendment to the U.S.Constitution and applies to state and local jurisdictions.
VOA: standard.2010.07.06
U And then if we can also determine delta u, then we know this, we know delta u is q plus w w, then we can determine work as well, right?
然后,如果我们也能定出△,然后我们知道这个,我们知道△U等于q加?
"Two-point-four billion dollars in highly competitive grants to develop the next generation of fuel-efficient cars and trucks, powered by the next generation of battery technologies all made right here in the U.S.of A,"
VOA: standard.2009.08.05
Right. Delta u is zero, and it's also equal to this.
同时也等于这个,所以q1等于负w1。
I don't know how much you read about the-- right now we are going through a major financial crisis, which started in the U.S.
我并不知道你读了多少...,现在我们正在经历一个严重的金融危机,它起始于美国
u=q+w All right, what is delta u? delta u is q plus w.
好,Δu是多少?Δ
UC So we can immediately write delta u C is Cv times T1 minus T2. Delta Hc C is Cp times T1 minus T2, right?
所以我们可以直接写出△,是Cv乘以,△HC是Cp乘以,对吧?
So here are results for pathway A, right, for delta u zero delta H zero. I didn't actually explicitly write it or did I?
这是路径A的结果,△U是零,△H是零,我没有明确地写出来,是吧?让我们把它再写一遍?
Delta u is zero, right? It should be completely second nature.
u=0,对吧?这应当,成为本能的答案了。
Yeah. You're jumping slightly ahead of me, but basically, I'm done when this is equal to 1 right? Because I get down to the base case, so I'm done when b u is over 2 to the k is equal to 1, and you're absolutely right, that's when k is log base 2 of b.
因为这就是最基本的情况了,因此当b/2的k次方等于1的时候就停止了1,你说的太对了,就是k等于b的以2为底的对数的时候,你们都坐的挺靠后的啊,我不知道是不是我讲的不太明白?
du/dT constant pressure is the direct derivative with respect to temperature here, which is sitting by itself under constant volume keeping this constant but there is temperature sitting right here too.
偏U偏T,p恒定是对,温度的直接微分,而它本身对体积不变,保持它不变,但是这里也有一个温度,这就是偏U偏V,T恒定。
U It's u, because u is to q plus w right, heat and work, but it's adiabatic. So there's no heat, exchange with the environment, and it's constant volume, so there's no p dV work, right.
什么是零?是U,因为,等于q加w,热量和功,但这是绝热的,所以系统与环境间没有热量交换;,同时它是灯体的,所以也没有pdV形式的功。
And we can we can do this in principle except for one important detail, which is that enthalpy just like energy u isn't measured on an absolute scale but on a relative scale, right?
除了一个重要的细节,就像能量U一样,它不是,以绝对标度度量的,而是以相对标度度量的,对吧?
