镧石

The correlative analysis of theotoliths' thermoluminescence result show that half width and peak point is related to the subgroup element、Lanthanide and actinium elements highly.

耳石热释光曲线与耳石元素和水体元素的相关性分析表明耳石热释光半高宽和峰位主要与耳石中的副族元素、镧系及锕系元素之间呈显著的相关关系。

Objective: To establish a method for determination of barium in drinking water by AAS with lanthanum-coated graphite tube.

Mineral resources: statewide total of iron, copper, lead, zinc, Gong, antimony, gold, silver, platinum group metals, vanadium, titanium, cobalt, tungsten, tin, molybdenum, bismuth, germanium, gallium, cerium, lanthanum, selenium, uranium, thorium, radium, beryllium, sulfur, arsenic, dolomite, silica, limestone metallurgical, chemical limestone, coal, peat, marble, stone finishes, Iceland spar, graphite, turquoise, agate 45 kinds of minerals and so on.

矿产资源：全州共发现有铁、铜、铅、锌、贡、锑、金、银、铂族元素、钒、钛、钴、钨、锡、钼、铋、锗、镓、铈、镧、硒、铀、钍、镭、铍、硫、砷、白云岩、硅石、冶金灰岩、化工灰岩、煤、泥炭、大理岩、饰面石料、冰洲石、石墨、绿松石、玛瑙等45种矿种。

The reaction of the mixed rare earth concentrate including monazite (REPO_4) and bastnaesite (REFCO_3) decomposed by CaO and NaCl additives in the temperature of 100～1000 ℃ was studied by means of XRD and TG-DTA.

用XRD和TG DTA热分析技术，研究了含独居石和氟碳铈镧矿的混合稀土精矿在100～1000℃焙烧过程中，添加CaO，NaCl时，REPO4和REFCO3的分解反应。

Generally the larger La~(3+) ion prefers the monazite type due to its higher oxygen coordination number of 9 as compared to 8 of the zircon type.

而EDTA作为模板剂除了螯合和诱导晶体生长外，还起到抑制镧离子形成9配位结构的作用，从而避免了单斜独居石结构晶相的产生。

A yellow trivalent metallic element of the rare earth group; occurs in monazite and bastnasite in association with cerium and lanthanum and praseodymium .

一种稀土属黄色多价元素，与铈、镧、镨共生于独居石和氟碳锑矿中。

Ago a kind of misconception that the rare earth metals is very scarce in nature, in fact not the case, many of which elements such as lanthanum, cerium, praseodymium, neodymium and samarium in accordance with their distribution in nature is no less well-known people in some of the elements of industry, common There ore monazite, scandium yttrium stone, silicon and cerium stone, stone and brown curtains and other fluorocarbon calcium cerium ore.

以前有种错误概念，认为稀土金属在自然界很稀少，其实不然，其中很多元素如镧、铈、镨、钕和钐按其在自然界的分布不次于人们在工业上熟知的某些元素，常见的矿石有独居石、钪钇石、硅铈石、褐帘石和氟碳钙铈矿等。

A soft, silvery-white, malleable, ductile, metallic rare-earth element, obtained chiefly from monazite and bastnaesite and used in glass manufacture and with other rare earths in carbon lights for movie and television studio lighting.

镧：一种质软、银白色、有延展性的、可塑性的稀有金属，主要是从独居石和氟碳铈矿中提取出来，用于玻璃工业及电影或电视摄影照明的碳棒灯中。

There will be much work to be done on the research of the utility of La-containing zeolites.

关于含镧沸石的应用，还有待于进一步的探讨。

The TiO2/zeolite doped with each of rare earth ions La3+,Nd3+,Yb3+ was prepared from tetrabutyl titanate and rare earth oxide by solgel process.

以钛酸丁酯和稀土氧化物为原料，采用溶胶凝胶法制备了镧、钕和镱稀土离子掺杂TiO2/沸石光催化剂。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
