Spectrometric analysis of titanium alloys part 14 : determination of yttrium content - inductively coupled plasma atomic emission spectrometric method 钛合金化学成分光谱分析方法.第14部分:电感耦合等离子体原子发射.光谱法测定微量钇含量
Another method of increasing vortex pinning involves adding microscopic inclusions of some second material such as yttrium oxide or titanium diboride 另一个增强涡流固定效果的方法是加入第二种材料的小颗粒，例如氧化钇或是二硼化钛。
Praseodymium oxide - determination of lanthanum oxide , cerium oxide , neodymium oxide , samarium oxide and yttrium oxide contents - x ray fluorescence spectrometric method 射线荧光光谱法测定氧化镨中氧化镧氧化铈氧化钕氧化钐和氧化钇量
Rare earth elements ( rees ) consist of lanthanide series with atomic numbers from 57 to 71 , as well as scandium ( atomic number 21 ) and yttrium ( atomic number 39 ) 稀土是指原子序数从57到71的镧系元素以及与其同族的钪和钇，共有17个元素。
Cerium and cerium oxide - determination of lanthanum oxide , praseodymium oxide , neodymium oxide , samarium oxide and yttrium oxide contents - emission spectrographic method 发射光谱法测定金属铈及氧化铈中氧化镧氧化镨氧化钕氧化钐和氧化钇量
Neodymium and neodymium oxide - determination of lanthanum oxide , cerium oxide , praseodymium oxide , samarium oxide and yttrium oxide contents - emission spectrographic method 发射光谱法测定金属钕氧化钕中氧化镧氧化铈氧化镨氧化钐和氧化钇量
The rule is that with the increasing of yttrium ' s contents , the granularity , the circular - degree and the distributing - leveling of the quasicrystals are improved 其规律为，伴随y含量的增加，准晶体的晶粒度、圆整度和分布均匀化程度均有提高。
