【摘要】 块状单畴高温超导体的重要特性参数之一"俘获磁通密度"决定了单畴超导体能够冻结住的最大磁通俘获场,实际用户在设计装置时必须了解这些参数.然而,这些数值强烈地依赖于测试方法.随着国内块状单畴超导体的研究、生产、应用的不断发展,市场规模的不断扩大以及国际贸易的开展,迫切需要建立一个与国际接轨的测试标准,统一材料提供方与用户之间对单畴块材性能的表征过程.经国家标准化管理委员会批准,2013年全国超导标准化技术委员会将IEC 61788-9国际标准《SUPERCONDUCTIVITY-Measurements for bulk high temperature superconductors-Trapped flux density of large grain bulk oxide superconductors》(《超导电性:块状高温超导体的测量—大晶粒氧化物超导体的俘获磁通密度》)转化为国家标准,本文主要介绍有关"标准"的转化实施过程.更多还原

【Abstract】 Trapped flux density is one of the important parameters of high temperature superconducting single domain bulks,which determines the maximum magnetic field that the bulk superconductor can generate.The users of bulk superconductors must know the value ofthe trapped flux density for the design of their devices.However,it is strongly dependent on testing method,and therefore it is critically important to set up a national standard for determining the value both for domestic manufacturers and industrial users.It is commissioned by National Standardization Management Committee(NSMC)that Standardization Technology Committee of China Board of Superconductor Division has transformed international standard IEC617889《SUPERCONDUCTIVITY-Measurements for bulk high temperature superconductors-Trapped flux density of large grain bulk oxide superconductors》into the Chinese national standard.In this paper,the details on the translation work were introduced briefly.更多还原
