新 的 突 破 1984年春,一种被称为第三代稀土永磁材料──钕铁硼,在中国科学院物理研究所和中国科学院电子研究所的实验室里诞生了.我国成为继日本、美国以后第三个研制成功这种新材料的国家.钕铁硼是迄今世界上磁性最强的永磁材料.它在许多领域有着重要应用.因而,它成为国际磁 New breakthrough In spring of 1984, a kind of rare earth permanent magnet material called NdFeB was born in the laboratory of Institute of Physics, Chinese Academy of Sciences and Institute of Electronics, Chinese Academy of Sciences, China became the second generation after Japan and the United States The third country to successfully develop this new material, NdFeB is by far the most magnetically permanent magnet in the world, and it has important applications in many fields. As a result, it becomes an international magnet
