常見例句雙語(yǔ)例句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。原聲例句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。麻省理工公開課 - 化學(xué)原理課程節(jié)選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 米每秒平方耶魯公開課 - 基礎(chǔ)物理課程節(jié)選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)我們說到s軌道時(shí)。麻省理工公開課 - 化學(xué)原理課程節(jié)選 返回 squared value
