| 当玻璃中PbO引入后，Pb2+电子层最外层两个未配对的6S电子，这两个未配对电子存在，使Pb2+离子极化率极高而且易被O2-极化，极化导致离子变形和离子间距缩短，从而不仅部分使Pb-O间距进一步缩短，而且场强增大，对O2-吸引力增强，使Al-O与Si-O键力减弱。 |

| After adding PbO to glass, due to the existence of two unpaired electrons in the outermost shell of the Pb2+ electron layer, the Pb2+ ion becomes polarized and absorbs the O2- anion easily. Such polarization causes changes in the ions, shortening distances between ions, thus resulting not only in closing the distance between Pb and O ions, but also increases the force field. This in turn causes O2- to increase attraction such that the bonds between Al and O, as well as Si and O to be weakened. |
