常見(jiàn)例句雙語(yǔ)例句If you call this plus, then if you get a minus sign, you know that the velocity is in the opposite direction.你若稱(chēng)此爲(wèi)正號(hào)，你若想要一個(gè)負(fù)號(hào)，你們知道的,相反方曏的速度。Similarly, if m is equal to either plus 1 or minus 1, py we would in turn call it the p y orbital, or the p x orbital.類(lèi)似的，如果m等於+1或，我們可以叫它，或者px軌道。The magnitude is one, of course and the momentum, if I leave this off we would call that minus one because it's a one-dimensional problem.大小是1，而動(dòng)量是，如果我們忽略不計(jì)，可把它稱(chēng)作負(fù)一,因爲(wèi)這是一維問(wèn)題。原聲例句1 Similarly, if m is equal to either plus 1 or minus 1, py we would in turn call it the p y orbital, or the p x orbital.類(lèi)似的，如果m等於+1或，我們可以叫它，或者px軌道。麻省理工公開(kāi)課 - 化學(xué)原理課程節(jié)選 返回 call if minus
