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。

The USM is a kind of new electrical motor which develops in recent 20 years, it broke through the traditional concept of electrical motor. It didn"t have the electromagnetism winding and the magnetic circuit, and it didn"t uses the mutually electromagnetism to transform the energy, moreover, the volume of electrical motor is small, the weight is light, the transfer efficiency is high. For it was so small, so light, and so thin, it have begun to use on automobile. But the usage of superconductivity electrical motor is still in the experimental stage at present. The main reason is that the super conductivity material has not realized the high temperature, but with the development of technical, the possibly uses of superconductivity electrical motor in the big horsepower like automobile generator and on actuation electrical motor causes the electrical machinery to be smaller in volume, lighter in weight, and higher in efficiency.

超声波电机是近二十年来发展起来的一种新型电机，它突破了传统电机的概念，没有电磁绕组和磁路，不用电磁相互作用来转换能量，体积小、重量轻、转换效率高，很小、很轻、很薄，在汽车上已经开始使用；超导电机的使用目前还处在实验阶段，这主要的原因是超导材料还没有实现高温化，但是，随着技术的发展，超导电机可能使用在汽车的起动机和驱动电机这些大马力上，使原有的电机体积更小，重量更轻，效率更高。
