用ＸＲＤ、ＳＥＭ和ＥＤＳ研究了用三源分别蒸发和单溶液源超声雾化蒸发ＭＯＣＶＤ－ＹＢＣＯ／Ａｇ超导膜的显微组织和成分。两种工艺所制ＹＢＣＯ样品的ＴＣＯ为８８～９１Ｋ。静态沉积ＹＢＣＯ／Ａｇ膜的电流密度Ｊｃ高于动态沉积样品。其中单溶液源超声雾化ＭＯＣＶＤ－ＹＢＣＯ／Ａｇ膜的Ｉｃ和Ｊｃ最高达到３５８Ａ和２２×１０５Ａ／ｃｍ２（７７Ｋ，０Ｔ）。
The microstructure and composition of the MOCVD-YBCO / Ag superconducting film were studied by XRD, SEM and EDS respectively with three sources of evaporation and single source ultrasonic atomization. The TCO of YBCO samples made by the two processes is 88-91K. The current density Jc of the YBCO / Ag films deposited statically was higher than that of the dynamically deposited samples. Among them, the Ic and Jc of the MOCVD-YB-CO / Ag film were up to 3.58A and 22 × 105A / cm2 (77K, 0T) respectively.
