中文摘要：

研究了TFA—MOD法在铝酸镧基体上制备YBCO超导薄膜时不同初始热处理温度对薄膜的影响。通过XRD、Raman光谱和SEM等手段，对生长过程中的YBCO超导薄膜结构进行表征、分析，探讨了YBCO的生长机制。

英文摘要：

Epitaxial YBCO superconducting thin films was deposited by trifluoraceticacid - metal organic deposition method on single crystalline LaAlO3 （001） substrate, and microstructurc and superconductivity of YBCO thin films were analyzed by X - ray diffraction, scanning electron micrograph and Raman spectrum. We discussed the growth model of YBCO in the article.
