polar molecule

常見例句

They form a polar molecule, that is.
它們形成一個(gè)極性分子，也就是說。
Here is the question. Is methane a polar molecule or a nonpolar molecule? Let's look carefully.
問題是，甲烷是一個(gè)極性分子還是非極性分子,我們仔細(xì)看看。
If a non-polar molecule is subjected to an electric field, the electrons and nuclei are displaced and a diplo moment is generated .
如果一個(gè)無極分子被置于電場(chǎng)作用之下，則電子和核發(fā)生位移，從而產(chǎn)生一偶極矩。

Symmetric disposition of polar bonds still results in a nonpolar molecule.
空間對(duì)稱的極性鍵分布,還是會(huì)導(dǎo)致整個(gè)分子為非極性分子。

We only have the one bond so the actual HF molecule is polar, it has a net dipole.
但HF中只有一根鍵,所以分子也是極性的而甲烷中有一個(gè)網(wǎng)狀偶極。
