在O_2气氛下薄膜呈相对较多的金红石相。
More rutile peaks were observed in thin films annealed in O_2.
结果表明，随着环境温度的升高，所生成的二氧化钛颗粒的尺度变大，产物中金红石相含量增加，锐钛矿相含量减少。
The results indicate hat the size of TiO_2 crystallite increased and the crystalline phase transformed from anatase to ruffle with the rise of ambient temperature.
