narrow size film 中文意思是什麼
narrow size film
解釋
窄膠片-
Compared with host film, thickness and porosity of composite film change not much, while average and maximum pore size decrease, and pore size distribution range become narrow. further more, controlling reaction time can control the content of in - situ transforming fe3o4
結果表明，採用膜相滲透原位化學轉化法合成制備的fe3o4 / pvdf復合膜，其膜厚、孔隙率與原來的pvdf基體膜相比變化不大，平均孔徑、最大孔徑則有明顯減小，孔徑分佈范圍變窄，孔徑更趨于均勻，膜孔形態更為規整。 -
Research on tio2 includes nanoparticals, thin film, mesoporous materials and titanium oxide nanotubes. in this paper, tiox nanotubes were obtained by hydrothermal reaction from tio2 and the mixture solution of naoh and koh. these nanotubes can be regards as h2ti3o7 structure which have a narrow distribution in size which inter diameter and outer diameter are about 3 nm and 8nm, respectively
前面本論文報道了通過用tiq和naoh與koh的混合溶液反應，合成了一種具有hzti3o :結構的氧化欽納米管，最近研究發現發現當用koh取代混合堿液時，得到另一種一維納米結構的物質:納米線。
