The crystallization and orientation behaviors of BOPP film were discussed. The orientation features in crystalline and amorphous regions were compared.

介绍了BOPP薄膜的结晶行为和取向行为，分析了晶区和非晶区取向的不同特点。

XRD results indicate that amorphous titanium oxide film is formed on the surface after anodic oxidation, and corrosion rates of titanium crystal vary along different crystalline orientation.

经x射线衍射分析，纯钛表面经阳极氧化处理后，其表面生成了一层非晶态的氧化钛薄膜，并且钛晶体的各个表面沿不同结晶方向的腐蚀速率不相同。

This amorphous layer can serve as the buffer layer of the subsequent growth of the top SBN60 films and result in the high orientation of it.

总结起来就是非晶层成分的变化以及结构的缓冲导致SBN薄膜能以最低的能量生长。
