现在,美国发生了超过日本的超导热;而且在超导的研究开发体制、常温超导体的探索方面,美国远远超过了曾一度处于同一水平的日本。谈论美国的高技术而不考虑其同军事的关系是无意义的,而这正是超导体开发竞争的根本的目的。本文试图详细报告美国超导研究最前沿的情况。 At present, the United States has surpassed Japan's superconducting heat; moreover, the United States has far surpassed Japan once in the same level as the superconducting research and development system and the room temperature superconductor exploration. It is pointless to talk about the high technology of the United States without regard to its relationship with the military, and this is the fundamental purpose of competition in the development of superconductors. This article attempts to report in detail the forefront of research on superconductivity in the United States.
