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(huì)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(chǎng)論中場(chǎng)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(gè)力相同，除了,我的力沿著這個(gè)方向-,這是r的增長(zhǎng)方向-,所以我的力是,除以r的平方,如果我在這個(gè)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(huì)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。

You see an object in motion, you find a and you give a a certain numerical value, 10 meters per second squared.
你看到一個(gè)物體在運(yùn)動(dòng),你會(huì)發(fā)現(xiàn)它的 a,然后給 a 賦值,10 米每秒平方

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(huì)介紹角節(jié)點(diǎn),但我們今天講的是，徑向節(jié)點(diǎn)，徑向節(jié)點(diǎn)就是指，對(duì)于某個(gè)r的值,當(dāng)然，也包括psi的平方，等于,當(dāng)我們說(shuō)到s軌道時(shí)。
