由于美国没有一个具体的超导电性国家计划，也没有一个单独的政府部门或多个政府部门协作组织，制定一个全方面规划．因而要全面总结其超导电性方面的研究非常困难．美国国家科学基金（ＮＳＦ）根据提议并依据研究者的研究质量授权研究，其它政府部门根据提议内容和自身需要，? Since the United States does not have a specific national plan for superconductivity, nor does it have a single government department or a number of government departments and organizations to formulate a comprehensive plan. Therefore, it is very difficult to comprehensively summarize the research on its superconductivity. The NSF authorizes studies based on proposed and researched research quality, and other government departments, based on what they propose and what they need?
