超导材料获新突破前不久,中国科技大学研制成功零电阻温度高于130K的超导材料——铋、铅、锑、锶、钙、铜、氧超导体,创造了目前世界上超导临界温度的最高纪录。四种金属品被禁止出口经贸部自二月起已禁止铜及铜基合金、铝及铝基合金、镍及镍基合金,以及镍材四种商品出口。与此同时,还增加了对新闻纸、聚苯乙烯、聚丙烯、金属镁、橡胶等十六种商品实行出口许可证
Not long ago, China University of Science and Technology successfully developed a superconducting material with a bimodal resistance above 130K, namely bismuth, lead, antimony, strontium, calcium, copper and oxygen superconductors, and created the world’s superconducting critical temperature The highest record Four kinds of metal products are banned from export MOFTEC has banned the export of four kinds of copper and copper-based alloys, aluminum and aluminum-based alloys, nickel and nickel-based alloys, and nickel materials since February. At the same time, it also increased the export of newsprint, polystyrene, polypropylene, magnesium metal, rubber and other 16 kinds of goods export license
