The absolutely dry concrete,actually, is the good nonconductor, whose resistivity can be as high as 108 kΩ.cm, whereas the humid concrete is thought to be semiconductor and its resistivity is around 10 kΩ.cm.

绝对干具体，实际上，是良好的绝缘体，其电阻率可高达108kΩ。cm高，而潮湿的混凝土，被认为是半导体，其电阻率约为10kΩ。cm。

It was found that the resistivity of the TiO2, thin films deposited on Ti and Ti substrates increased non-linearly with the increase of the thickness of the films and varied in the range from conductor or semiconductor to nonconductor, respectively. The conducting layer thickness of the films deposited on different substarte materials is different and the films deposited on glass are nonconductors.

结果表明，沈积在Ti和Si基底上的TiO2薄膜的电阻率随著膜厚的增加而非线性增大，分别经历了导体、半导体到绝缘体或半导体到绝缘体的电阻率范围的变化过程， TiO2薄膜导电层厚度也不相同，沈积在玻璃表面TiO2薄膜为绝缘体。
