阐述了利用离子束分析技术分析高温超导氧化物陶瓷Ｙ－Ｂａ－Ｃｕ－Ｏ中各成分含量的一般原理．运用α粒子在３．０４５ＭｅＶ附近和Ｏ的弹性共振背散射以及卢瑟福背散射，得到了Ｙ－Ｂａ－Ｃｕ－Ｏ各成分的含量，并与质子Ｘ射线荧光分析的结果作了比较，提出了一种简单的背散射处理方法．该方法具有简单、快速、槽度高等优点．
The general principle of analyzing the content of Y-Ba-Cu-O in high-temperature superconducting oxide ceramic by ion beam analysis is described. The contents of Y-Ba-Cu-O were obtained by elastic resonance backscattering of α particles near 3.045 MeV and O and Rutherford backscattering, and compared with the results of proton X-ray fluorescence analysis A simple method of backscatter. The method has the advantages of simple, fast and high slot.
