1·The catalytic converter on your exhaust system contains cerium and lanthanum.
排气系统上的接触反应器含有铈和镧。
2·To give just one example, every Toyota Prius has over 25 pounds of lanthanum in its nickel-metal hydride battery.
举个例子，每辆丰田普瑞斯的镍合金电池里就有超过25磅镧族金属材料。
3·As soon as lanthanum takes that electron, this level rises ever so slightly, and then we jump down here and fill in the lanthanide.
一旦镧得到了电子，这一层就会稍稍上升，然后我们向下填一下镧系元素。
4·And they still may need to retest for other radioactive isotopes that had been found in the seawater around the No. 2 reactor, including troubling quantities of cesium, barium, cobalt and lanthanum.
并且，他们或许要对2号反应堆周边其他放射性同位素的含量，包括对铯、钡、钴、镧的浑浊度，进行重新检测。
5·Using an atomic force microscope and two layers of insulators (lanthanum aluminum oxide and strontium titanium oxide), Levy and his colleagues created a nanoscale transistor.
列维和他的同事们用原子力显微镜和两片绝缘体（镧氧化铝和锶钛氧化物），研制出了一枚纳米晶体管。
