【摘要】 在高 T_c 超导体的应用中,首先遇到和必需解决的是稳定性问题,特别是在潮湿空气和浸水条件下,对样品超导电性的影响.但在至今所进行的相应的研究中,都不能定量地测定样品中的水含量.本文采用热中子透射法测定了样品的水含量,从而定量地研究了水含量对超导样品性能的影响.更多还原

【Abstract】 For the application of the high-Tc superconductors the stability of their superconductivity is the first problem which we have to solve,specially when they work in moisture or water.There are several papers which discuss this subject,but up to now,we have not found any results of relationship of superconductivity with water quantity.In this paper,we introduce a method which measures the quantity of water in sample of YBa2Cu3O7-δ by thermal energy neutron transmission.更多还原
