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
And typically, we'll be treating at least some cases where we're dealing with ideal gases in which case we can easily get delta u.
那么我们也可以定出功,对吧?,典型地,我们至少会处理,一些理想气体的情况。
There's an index committee that keeps bringing in new shares when new companies become important; they try to get the 500 representative of the most companies in the world--in the U.S.
有一个指数委员会在新公司发展壮大的时候,一直持续替换新股,他们希望在美国,用500指数来反映,世界上大部分的公司
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?
So, I just want to write a few examples down with a few values for delta u or delta H or delta S, and see whether we can get any clues from what we see.
我先写一些例子,例子包含一些内能,自由焓和熵的变化数值,然后看从中,我们能不能得到一些启示。
This is from a U.S. Government website called treasurydirect.gov and you can get on and access it at any time.
来自于美国政府网站,treasurydirect.gov,你们也可以随时访问
And that in the case of constant volume, U in this case that's my delta u, and then I'll H add my little delta n term to get delta H.
这是在等体情形下,此时的到的是Δ,然后我可以加上Δn的项来得到Δ
