At this point , bardeen , cooper and schrieffer ( bcs ) produced their epochmaking pairing theory of superconductivity 当时巴丁、库珀和施瑞弗（ bcs ）提出了他们的划时代的超导电性配对理论。
Superconducting material is used , for example , in magnetic resonance imaging for medical examinations and particle accelerators in physics 超导电性和超流动性是在极端低温状态下发生的2种现象。
Mgb2 is discovered to be a superconductor at a remarkably high critical temperature - 38 . 5k , the highest in the similar metallic compounds Mgb2是2001年初报道具有超导电性的，其tc为38 . 5k ，在同类化合物中是最高的。
Because most researches on this subject use numerical approach , an analytical method is developed to investigate the property of mesoscopic superconductor 在ginzburg - landau理论框架内，发展了一种解析的处理方法研究了介观超导体的超导电性。
Physicists know that in both types of material , the superconductivity is caused by electrons pairing up and gathering en masse in a single collective quantum state 在这两种超导体材料中，超导电性是由于电子成双成对地集结在单一的量子态所产生，这是物理学家已知的部份。
Topics covered include crystal structure and band theory , density functional theory , a survey of properties of metals and semiconductors , quantum hall effect , phonons , electron phonon interaction and superconductivity 内容包括了晶体结构和能带理论，密度泛函理论，金属和半导体特性概论，量子霍尔效应，声子，电子-声子的相互作用以及超导电性。
