So this delta energy here is very simply the energy of the initial state minus the energy of the final state.
很简单的,这个能量差等于,初始能量减去末能量。
W1 So I have my initial state, my final state, W1 my initial state, my final state here.
再加热,做功,对系统做的总功是。
So we can't actually see any of that, it's too high energy for us to see. So everything we see is going to be where we have the final energy state being n equals 2.
所以我们是看不见它的,它能量太高了,我们能看见的,都是终态等于2的情况。
In my final slide is a picture of the first indexed bond; this is issued by the State of Massachusetts I actually own this bond.
最后一张幻灯片是,第一支物价指数债券的照片,这是麻省州政府发行的,其实我收藏了这张债券
How do you get from the initial state to the final state?
你是怎样,从初态过渡到末态的?
Define the initial state. Define the final state.
定义初态,定义末态,定义路径。
The sum of path number 2 and path number 3 get me to the same place, so the energy change by going through this time path, this intermediate point here back all the way to final state should be the same the red path.
而经过路径2和3可以3,到达同样的末态,因此经过路径,2和3带来的能量的变化,与路径1带来的,能量变化相同。
OK, so, the thing about a state function is that the function has a value for initial conditions and at final conditions.
态函数的特点是,在初始状态有一个值,在末状态也有一个值。
