2 ) morphology and electric properties of nanofilms of of tioi and batios two kind structures of tic > 2 nanofilms were obtained : the multihole network and the general granule film ; and the structure could be controlled by changing the preparation conditions 我们所得到的si - tio2薄膜，表面具有两种结构：多孔网络tio2薄膜和颗粒分布均匀较平整的tio2纳米颗粒薄膜。研究了两类纳米薄膜的微区电导特性。
