1986～1987年,超导研究在钇钡铜氧系和镧铜氧系等材料上取得了重大突破,超导器件在液氮温度区工作的目标已经实现。这一重大研究成果一旦实现实用化和商品化,必然导致一场新的工业革命。这一趋势已引起世界各国,尤其是先进工业国的极大关注。因此,作为超导材料的关键原料的稀土资源立即成了许多国家垂涎的目标。种种迹象表明,日本为争夺全球经济和技术的霸主地位,已把争夺超导技术产业市场作为一个重要的战略目标,并已制订出一个从资源到市场的超导产业的长远战略计划,他们瞄准的第一个目标就是中国。日本共同社1月5日的电讯报道,日本“为了在获得稀土资源的竞争中不落后,通产省将与中国协商共同开发超导材料问题”。日
From 1986 to 1987, superconductivity research made major breakthroughs in materials such as lanthanum-copper-oxygen systems and thorium-copper-oxygen systems. The goal of superconducting devices working in the liquid nitrogen temperature zone has been realized. Once this major research achievement is realized and commercialized, it will inevitably lead to a new industrial revolution. This trend has drawn great attention from all countries in the world, especially advanced industrial countries. As a result, rare earth resources, which are key raw materials for superconducting materials, have immediately become a coveted goal for many countries. All indications indicate that Japan has been contending for the dominance of the global economy and technology and has contend for the superconducting technology industrial market as an important strategic goal, and has formulated a long-term strategic plan for the superconducting industry from resources to markets. The first goal is China. Japan’s Kyodo News Agency’s telecommunications report on January 5th stated that “In order to not lag behind in access to rare earth resources, the Ministry of International Trade and Industry will negotiate with China to jointly develop superconducting materials.” day
