In fact , japanese imports of certain key chinese rare earths , including the oxides lanthanum and cerium , actually rose in 2010 from the previous year .

事实上，2010年日本从中国进口的某些关键稀土元素，包括镧和铈的氧化物实际上较前一年有所增加。

Global demand for materials such as lanthanum and neodymium was surging as the world 's appetite for hybrid cars , wind turbines and ever-faster phones with better screens increased .

随着混动汽车、风力涡轮机和速度越来越快、屏幕越来越好的手机需求增加，镧、钕等材料的需求出现井喷。

Rare earths are 17 chemically similar metallic elements such as europium , yttrium and lanthanum that have unique magnetic , optical and other properties crucial for miniaturisation , lasers and energy efficiency .

稀土是指17种化学上相似的金属元素，如铕、钇和镧，它们具有独特的磁性、光学性和其它特性，对微型化、激光和能源效率至关重要。

A kilogram of lanthanum oxide -- used in oil refining and hybrid vehicles -- now fetches just us $ 13 a kilo , compared with an average us $ 104 a kilo last year .

用于炼油和混合动力汽车的氧化镧现在仅卖到每公斤13美元，相比之下，去年的价格是平均每公斤104美元。

Taking the first 11 months of 2010 together , japan 's imports of chinese lanthanum oxide jumped a whopping 259 % from the same period in 2009 .

按照2010年前11个月计算，日本从中国进口的镧氧化物规模比2009年同期大幅增加了259%。
