It's just the number that was picked between 1 and 10 that's probably bigger than 5 or 6, not smaller.
它产生一个在1到10之间的数0,或者大于等于5或者6的数。
OK. If last minus first is greater than or equal to 2-- sorry, less than 2, then either look at this thing or look at that thing.
大于等于儿,抱歉,是小于二,看看这里或者那里,这就是我说的要特别小心的地方。
So, we do this here for the photoelectric effect, and in terms of the photoelectric effect, what we know the important point is that the incoming photon has to be equal or greater in energy then the work function of the metal.
所以,我们做这个是为了说明,光电效应,在光电效应方面,我们知道的最重要的事情,就是入射的光子能量必须等于,或者大于金属的功函数。
We saw that in general dS is greater than T or equal to dq over T.
我们发现一般来说dS大于,或者等于dq除以。
And keep going, until the square of one of those integers is greater than or equal to - sorry, just greater than x. OK, why am I doing that? When I get greater than x, I've gone past the place where I want to be.
如果还是比x小的话,跳到3,这么继续下去,直到一个整数的平方大于或者等于,对不起,是大于x,好,为什么我要这么做呢?,让我得到的整数的平方和。
z And what you need to remember is if the z 8 is equal to eight or greater, such as oxygen being the cut-off point, this sigma 2 p orbital is actually lower in energy than the pi 2 p orbitals, the molecular orbitals.
你们要记住如果,等于或者大于,就像O是分界点,这时sigma2p轨道,比π2p轨道能量更低。
