Yale University is a non-profit corporation; the price of a share in Yale University is undefined-- it's zero over zero.
耶鲁大学可以看作是个非盈利组织,它的股价无法定义,是零除以零
Actually, you can't say what the share price is because there are zero shares and they have a zero price, so the value of the price per share is zero over zero and you can't define it.
实际上你并不能确定它的股价多少,因为股数为零,其市值也为零,所以每股价值就是,零除以零,无法计算
And a bit, B-I-T, just a shorthand for binary digit, 2 so a digit of zero over a one, bi means two, you only have two digits.
比特,B-I-T,是binary,digit的简写,从0到1的数字,而bi表示,所以你就只有两个数字。
Obviously, if the balance of pleasure over pain is positive, that's better than zero.
显然如果快乐减痛苦是正的,即比零大。
q1*q2/ That's simply q1, q2 over 4 pi epsilon zero R.
那只是简单的。
Going around in a cycle the integral of dq over T is less than or equal to zero.
对一个循环过程作dq除以T的积分,小于等于零。
t the new deal, s over , by the unemployment is down to close to zero by the middle of the War.
如果不是新政,If,it,wasn’,萧条结束,it’,失业率也降低到接近零点,在二战中的时候。
du/dV So now our du/dV, dp/dT at constant T is just T times dp/dT which is just p over T minus p, it's zero.
现在我们的恒定温度下的,等于T乘以dp/dT,在这里,等于p除以T,最后再减去p,结果是0。
So that's it; it's over; we've just hit zero.
所以,它结束了;我们已经达到零点了。
e The charge on the anion times minus e, so there is the minus e squared, 0R0 and divided by 4 pi epsilon zero r naught, because now I am evaluating this function at r naught, one minus one over n where n is the Born exponent.
阴离子的电荷乘以,因此会有-e的频繁,除以4πε,因为现在我用r圈评估这个函数,1-1/n,n是波恩指数。
I know the energy in this first pair would equal -e^2 That is just going to equal minus e squared over 4 pi epsilon zero r naught.
我们明白第一对的能量将会等于,等于,/4πε0,R圈。
Right. N is over here for counting from zero.
对的,从0开始计数,N到了这边。
And now the force, in its most general term / is q1q2 over 4 pi epsilon zero, which is the conversion factor r squared.
库仑力的最基本形式,就是,其中r是一个变量。
And we wrote something that looks, the energy is equal to minus the Madelung constant times Avogadro's number, 0R0 q1 q2 over 4 pi epsilon zero R zero.
我们写下了,晶格能等于负的马德隆常数,乘以阿伏伽德罗常数,乘以q1q2除以4πε
