squared value

基本解釋

You'll notice that there's a little bit of a difference in these equations here from the ones from the other day, which is that you have z squared value in there.
你們會注意到這里的方程,和我們那天的方程,有些小的不一樣，這里有z平方。
This is reflected in the fact that the vacuum expectation value of the field squared is nonzero in quantum field theory. Therefore there exist the so called vacuum fluctuations.
這反映在量子場論中場量平方的真空平均值不為零，這就是所謂的真空漲落。
The two are identical except that - mine is in this direction-- - this is increasing value of r-- +mMG so mine would be plus m MG divided by r squared if I'm here at location r.
這兩個力相同，除了,我的力沿著這個方向-,這是r的增長方向-,所以我的力是,除以r的平方,如果我在這個位置。

You'll notice that there's a little bit of a difference in these equations here from the ones from the other day, which is that you have z squared value in there.
你們會注意到這里的方程,和我們那天的方程,有些小的不一樣，這里有z平方。

We'll introduce in the next course angular nodes, but today we're just going to be talking about radial nodes, psi and a radial node is a value for r at which psi, and therefore, 0 also the probability psi squared is going to be equal to zero.
將會介紹角節(jié)點,但我們今天講的是，徑向節(jié)點，徑向節(jié)點就是指，對于某個r的值,當然，也包括psi的平方，等于,當我們說到s軌道時。
