钇钡铜氧化物陶瓷把超导材料的转变温度提高到90K以上,这是一个重大的突破.然而,有试验表明测量电流的大小对这种材料的转变温度有极其明显的影响,测量电流从2mA变到50mA转变温度降低了近20K.因此,如何提高它的电流密度,把它做成具有实用价值的元件,这将是下一个突破.这个突破很自然地要建立在对材料的微观组成充分了解的基础之 Yttrium barium copper oxide ceramics increase the transition temperature of superconducting materials above 90 K, which is a major breakthrough.However, some experiments show that the size of the measured current has a very significant impact on the transition temperature of this material. The measurement current from 2mA change to 50mA transition temperature decreased by nearly 20K.Therefore, how to increase its current density, make it a practical value of the component, it will be the next breakthrough.This breakthrough is very natural to be based on the microscopic composition of the material Fully understand the basis
