The flux of electric field intensity E through a closed surface is equal to zero, which means in the surface A: there are more positive charges than negative charges. B: there are more negative charges than positive charges. C: there are the same quantity of the positive charges and negative charges. D: there is no polarized chargeharge.

关于Lens以下说法正确的是（） A: 光学镜架需要装配光学镜片，但在配镜之前需要装配DemoLens做支撑 B: 太阳镜片可能是玻璃的，但没有办法做宝丽来偏光片（Polarized），而且装配困难，价格昂贵 C: CR39片和PA片韧性比较好，不会出现开裂问题，所以框撑变形了也没有关系 D: PC片抗瞬间冲击能力强可以当作护目镜用，抗疲劳应力能力强，所以不怕变形
