The redesigned motor still uses the lightrareearthelement neodymium, which is found in North America and Australia, as well as China.
重新设计的电机仍使用了轻稀土元素钕,北美、澳大利亚和中国都有这种矿藏。

The rare gas isotope geochemical analyses also support that there is a genetic association between the lightrareearthelement mineralization and mantle processes.
稀有气体同位素地球化学研究也在一定程度上揭示了牦牛坪轻稀土矿化与地幔过程之间存在着成因关系。

It gave the process design of four-elementlightrareearth separation and showed the result of dynamic equilibrium imitation by computer.
