元素鈰 的英文怎麼說
中文拼音 [yuánsùshì]
元素鈰
英文
ce-
The lighter rare-earth metals, from cerium to europium in the first half of the series, have more complex crystal structures than the heavier elements.
輕的稀土金屬，從鈰到銪的前一半序列比重元素具有更為復雜的晶體結構。Activated agent of cerium that is abundant and cheap together with a little terbiumas additive is used in the study, to research and explore luminescent mechanism of aluminates strontium
本研究擬選用原料豐富、價格便宜的輕稀土元素鈰作敏化劑，以鋱作激活劑，對其在鋁酸鍶基體中的發光機理這一新領域進行研究和探討。The wall rock of ore - bodies is the siliceous dolostone and alkaline volcanic rock ( trachy andesite ) in the yinachang deposit. based on the shape of ore - bodies and the structure and texture of ores, the deposit was identificed as synsedimentary with wall rocks. there occurred ree minerals, such as bastnaesite, monazite and allanite, associated with apatite and fluorite with ree contents to a certain extent
礦體產出形態和礦石的結構構造等均顯示礦體與賦礦地層同沉積特徵；出現獨立礦物氟碳鈰礦、獨居石及褐簾石，磷灰石、螢石、菱鐵礦等礦物中也含有一定量的稀土，沿礦體走向和垂向稀土元素變化不大。According to the sample prepared by hydrothermal method, the doping cations can enter the spinel lattice. rare earth cations mostly occupy position b because of their big radius. cerium are oxidized to ce4 +, whose radius is relatively small, and ce4 + mostly occupies position a. as a whole, the coercivity of cobalt ferrite doped with rare earth element is bigger than that of pure cobalt ferrite
結果表明，對水熱法制備的鐵氧體粒子，雜質離子能夠進入其尖晶石晶格中，並因稀土離子的半徑較大，而絕大部分佔據尖晶石的b位，鈰元素因被氧化成為四價離子，離子半徑相對較小，而主要佔據a位。Determination of the cerium subgroup of rare earth elements content - tribromoarsenazo spectrophotometric method
