Studies of Sr, Nd and Pb isotopes of various stratigraphic units, granite plutons and fluorite ores indicate that the metallogenic materials of fluorite were derived from multiple sources, and the isotopic composition of fluorite is characterized by crust_mantle mixed sources.

各地层单元、花岗岩体和萤石矿石的Sr、Nd、Pb同位素研究表明，萤石的放射性同位素组成具有壳、幔源混合的特点，成矿物质来源具有多源性。

The invention provides an anhydrous hydrogen fluoride production process; reaction raw materials fluorite powder and sulfate are mixed by an external mixer and enter into a converter with jacket; hot air with the temperature of 350 DEG C to 600 DEG C is fed in the jacket; the fluorite powder and the sulfate have chemical reaction and produce hydrogen fluoride; the produced hydrogen fluoride enters into a scrubber from a furnace header to be washed; the washed hydrogen fluoride enters into an intermediate tank from a condenser, and then receives distillation and degasification to prepare the finished product anhydrous hydrogen fluoride; solid residue is emitted from a furnace tail.

本发明提供一种无水氟化氢生产工艺，反应原料萤石粉及硫酸经外混器混合后进入带有夹套的转炉，向夹套内通入350～600℃的热风，萤石粉和硫酸在发生化学反应生成氟化氢，生成的氟化氢气体由炉头进入洗涤塔进行洗涤，洗涤后的氟化氢由冷凝器进入中间槽，然后经过精馏、脱气制得成品无水氟化氢；固体残渣由炉尾排出。

When the molar fraction of SnO2 is 83%, the main component of the coating isO2 solid solution with rutile structure. When the molar fraction of SnO2 is 44%, the main components of coating are theO2 solid solution with rutile structure andO2 solid solution with fluorite structure. When the molar fraction of SnO2 is 17%, the main component of the coating isO2 solid solution with fluorite structure. Annealed at higher temperature than 450 ℃, CeO2 is found in the coating containing 83%Sn, and there is not SnO2 in the coating containing 83%Ce, which suggests that fluoriteO2 has higher thermal stability than rutileO2. When the molar fraction of SnO2 increases, the dispensability of the coatings is improved greatly.

结果表明：通过控制制备条件可获得具有纳米结构的钛阳极涂层；当Sn的摩尔分数为83%时，涂层主要为金红石相的O2固溶体；当Sn的摩尔分数为44%时，涂层中金红石相O2固溶体和萤石结构的O2固溶体共存；当Sn的摩尔分数为17%时，涂层由萤石结构的O2固溶体组成；高于450 ℃退火时，含83%Sn的涂层中出现CeO2相，而在含83%Ce的涂层中没有出现SnO2相，表明在相同的溶质浓度下，萤石结构的O2固溶体比锡基金红石相O2固溶体具有更好的热稳定性；而涂层中的SnO2具有明显改善涂层分散性的作用。

fluorite：氟石

燃烧某种药草和植物,如艾草,以及淋浴或泡於水中等都能用来清涤气场,而某些水晶矿石和宝石则有助於治疗气场. 例如,可以把氟石(fluorite)高举在头顶十五秒,此时该晶石内的能量会放射出来,而它亦可以在十~十五秒内自动充能.

fluorite：瑩石

这里主要指的是佳能EF镜头中使用了莹石(Fluorite)镜片或磨削非球面镜片的镜头称为"L"镜头. 这种镜头的标志是镜头前端的红色标线,是佳能的高档专业镜头. APO镜头是指这些镜头采用复消色散设计和特殊低色散玻璃(SLD)镜片,

fluorite：石

另一个特色是,Sigma 新开发了 FLD 镜片,这是一种人工萤石,可以提供较 高的透光性,并且具备如同莹石(Fluorite)一样,有较低的折射率跟低色散表现,并使镜头拥有更高的解析力和对比度,当然,在价格上,也会比原厂低 廉.
