In chapter 1, the progress in study of the ruthenium complex oxides. especially the coexistance of magnetism and superconductivity in 〓 and 〓 are introduced. The introduction makes conclusion that all of the Ru-1212 and Ru-1222 compounds reported are accompanied by small amounts of SrRuO〓 impurities, this is to say that, it is difficult to synthesize pure samples of these two compounds by traditional solid state reaction. So the author think that the studies for new synthesis methods of ruthenate superconductors which is beneficial to the synthesis of new type precious metals superconductivity is very important till now.

第一章重点综述了钌系复合氧化物的研究进展，特别是其中超导电性的发现及其钌系1212、1222相铜氧化物超导电性和铁磁性共存的特征，在此基础上可以看出，至今文献报道所获得的Ru-1212和Ru-1222相化合物都含有少量的SrRuO〓杂相，即很难通过原有的固相反应方法得到纯相化合物，由此作者提出，现有钌系超导氧化物合成的新方法研究仍具有重要的现实意义，这也将更有利于探索合成新型贵金属超导体。

At extremely low temperatures, some metals and alloys lose their resistance to electrical current and become superconductive.

在极低的温度下，某些金属和合金失去其对电流的电阻变成超导体。
