A massive, 'semi-infinite' trove of rare-earth metals has been found in Japan
最新消息：日本南鸟岛海域发现大量稀土金属资源！
Researchers have found hundreds of years' worth of rare-earth materials underneath Japanese waters — enough to supply to the world on a "semi-infinite basis," according to a study published in Nature Publishing Group's Scientific Reports.
根据发表在自然出版集团《科学报告》中的一项研究表明，研究人员在日本海域发现了稀土资源，可供全世界在半无限的基础上使用数百年。
Rare-earth metals are crucial in the making of high-tech products such as electric vehicles and batteries, and most of the world has relied on China for almost all of its needs.
要制造高科技产品，比如电动汽车和电池，稀土金属是至关重要的。而世界上大部分国家的稀土需求基本都依赖于中国。
The seabed contains more than 16 million tons of rare-earth oxides, according to the study. That's equivalent to 780 years' worth of yttrium supply, 620 years of europium, 420 years of terbium and 730 years of dysprosium
该研究表明，日本海底含有超过1600万吨的稀土氧化物，其中，钇可供全世界使用780年，铕可供全世界使用620年，铽可供全世界使用420年，镝可供全世界使用730年。
