It's much more relevant to set our zero point energy as the separation of a bond in terms of talking about the reactions that we'll usually be dealing with here.
更好的是把零点能定在,键断裂的时刻,在讨论化学反应的时候,而我们以后将经常遇到化学反应。
Then they should be pricing whatever they're selling at a lower price
那么他们应该把所卖的物品价格定得低一点
Schrodinger said I am going to take that same idea, and I am going to apply it to a larger scale system.
薛定谔说我将用同样的思路,我要把它用到一个更大的系统中。
As small an amount below his price as you can do.
尽量把价格定的只比他低一点
I can lock in the interest rate right now.
我现在就可以把利率定下来
I have to find out exactly the right time.
我还没把具体时间定下来
So I said before when we were talking about single atoms, we always define the zero energy as when an electron was actually ejected, but now, when we talk about chemical reactions taking place, it's very, very rare that we're actually going to be talking about anything that gets to this point here.
我之前说过,当我们讨论单个原子的时候,我们总是把零点能,定在电子被发射出去以后,但是现在,当我们讨论化学反应发生的时候,非常非常罕见出现,确实达到,这种程度的情况。
We saw the Schr?dinger equation for atomic hydrogen, but you can write it for more complex systems.
我们看过原子氢的薛定谔方程,但其实我们能把他用在更复杂的体系。
And notice that if Pepsi has priced above the monopoly price, suppose Pepsi has priced this good so high that it's above the monopoly price, then, as the gentleman said, I can capture the whole market by pricing just below Pepsi.
注意如果百事设定的价格高于垄断价格,假设百事把价格定得太高了以至于,高于垄断价格,那么像那位先生说的,我可以用低于百事的价格来占领整个市场
When we first introduced the Schrodinger equation, what I told you was think of psi as being some representation of what an electron is.
当我们第一次介绍,薛定谔方程的时候,我说你们,可以,把psi看做是,电子位置的代表。
