Because the oxidate was dispersed in the material, oxyfluoride materials have excellent chemical and mechanical properties, more easy to be prepared than the fluoride glasses or crystal.

由于氧化物的存在，这种材料有稳定的化学、力学性能，比氟化物玻璃或晶体更易于制备，从而在光纤放大器、上转换激光器及显示方面有广阔的应用。

Babies who are exposed to fluoride have a higher risk of getting dental fluorosis, which is a permanent tooth defect arising when fluoride damages the cells which form the teeth.

Mao Ling Duan said that although the human body can be from day-to-day diet to fluoride intake, and intake hard enough, the development of early childhood tooth growth will be affected, so early childhood development in the permanent tooth germ plus if the participation of fluoride Heng Calcified teeth, the permanent teeth grow in the future will be more acid-resistant.

段茂玲表示，人体虽可自日常饮食中摄取到氟，却难足量摄取，对发育中的幼儿牙齿生长会有影响，所以，幼儿发育中的恒牙牙胚若有外加的氟化物参与恒牙钙化，未来生长出来的恒牙会更耐酸。

Methods SH-SY5Y cells, a human neuroblastoma cell line, were incubated with different concentrations of fluoride for 48 hr and somle of them were treated with vitamin E precedently. The functional situation of cells was measured by MTT method; lipid peroxidation was detected by High-Performance Liquid Chromatography; phospholipid was separated by a Silica SepPak cartridge and neutral lipids by HPLC.

体外培养SH-SY5Y人脑神经母细胞瘤细胞，在培养液中加入不同浓度的氟化物或加入抗氧化剂，培养48h后用测定细胞MTT的方法来了解细胞的损伤程度，用高效液相色谱法分离和测定培养液中脂质过氧化物水平，用过柱和比色法测定细胞生物膜磷脂含量，用高效液相色谱法测定细胞生物膜辅酶Q和胆固醇含量。

Contaminant cations such as calcium,magnesium,barium,strontium,and radium and anions such as fluoride ,nitrate,fulvates,humates,arsenate,selenate,chromate ,and anioic complexs of uranium can be removed from water by using ion exchange or adsoption onto activiated alumina.

具有污染能力的像Ca，Mg，Ba，Sr，Ra的阳离子，和像氟化物，硝化物，黄酸物，腐质酸物，砷酸盐，硒酸盐和铬酸盐的负离子以及像铀一样的负离子复合物可以通过离子交换和离子吸附从水中排除。

A complex sample containing BMP and sodium fluoride was implanted under the abdominal skin of young male Wistar rats.

在纯化的BMP中加入氟化物再植入大鼠皮下，通过比较植入物在不同植入时间的组织学变化，碱性磷酸酶、酸性磷酸酶活性及钙含量来反映BMP的生物活性。

TEM images showed that LaF3, PrF3, NdF3 and SmF3 nanoparticles were spherical or spherical-like with mean diameter of about 35~39 nm.

结果表明，稀土氟化物纳米粒子具有球形或类球形的形貌，平均粒径为35~39nm。
