含镧系元素的结构类似的程序提供了更大的欺骗范围。 Similar procedures with structures containing lanthanide elements offered even greater scope for deception. | ||
稀土元素也称镧系元素，化学性质与锕族元素(89到104)相似。 Rare earths, also called lanthanides, are chemically similar to actinides (89 through 104). | ||
并非所有稀土元素都像钪、钇、镧加上14所谓的镧系元素那样稀少。 It is not as though the rare-earth elements-scandium, yttrium and lanthanum plus the 14 so-called lanthanides-are all that rare. | ||
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。 As soon as lanthanum takes that electron, this level rises ever so slightly, and then we jump down here and fill in the lanthanide. | ||
因此，要记住，当你在看元素周期表时，不要忘了镧系元素，有时候也会用到它们。 So, remember when you're looking at your periodic table, don't forget about the lanthanides, sometimes they come into play. | ||
提要稀土是化学元素周期表中的镧系元素和化学性质相似的钇、钪共17种元素的统称。 ABSTRACT Rare earth is a collective name for 17 elements including ytterbium (Yb), scandium (Sc), and lanthanide series. | ||
芳香环谱带的相对强度和频率对于镧系元素原子序数的依赖关系表明双-双效应的存在。 The dependence of relative intensity and frequency of bands of aromatic ring on the atomic number of lanthanides indicates the presence of a double-double effect. | ||
第一种是在在矽（111）基板上成长氧化矽，并将镧系元素-铽，以离子布植的方式植入样品。 One of them is to implant terbium ion into silicon oxides thin film which is grown on Si(111) substrates. | ||
