fluorosilicic acid meaning in English
氟硅酸
Examples
- Abstract : the iodine is extracted from fluorosilicic acid solution by carbon tetrachloride after the iodine ion is oxidized to the free iodine . the oxidant b is adopted through sifting oxidants
摘要对氟硅酸提碘过程的氧化剂进行选择研究，结果表明，对碘回收率而言氧化剂b较好。 - As quartz fraction in loess is separated by the tedious process of etching with fluorosilicic acid for 6 days , 20ml 30 % fluorosilicic acid per gram , not only the feldspars in loess could be removed completely , but also less quartz could be etched away in loess
溶蚀实验表明，用40 hf溶蚀40min对石英的损失太大，不适合黄土中石英的分离。用30氟硅酸（ 20ml冶）溶蚀约6天，分离黄土中的石英颗粒，既可以溶蚀掉长石颗粒，又对石英的损失较小。 - In order to elaborate the app licability of osl to loess , especially single aliquot regenerative protocol ( sar ) , involving stimulation of the same disc with an infra - red laser diode followed by blue leds to polymineralic fine - grains of loess , such explanations as light bleaching , preheat , anomalous fading , prior - ir exposure were investigated in this paper . for drawing adequate coarse grains from loess , quartz and feldspars , as well as loess , were etched by hydrofluoric acid and fluorosilicic acid . the sequence of ages of holocene loess in weihe rivier basin has been established by single - aliquot ( sar ) and multiple - aliquot using fine - grains and sar using coarse - grains
本文通过渭河流域全新世黄土的光晒退实验，地表黄土样品的d _ e值测定，细颗粒单片的预热、反常衰退、红外暴露实验，说明释光测年在全新世黄土中应用的可行性及单片再生剂量法( sar )在黄土细颗粒中的适用性；为了从黄土中分离出足够的粗颗粒，进行了纯石英和长石的氢氟酸( hf )和氟硅酸( h _ 2sif _ 6 )溶蚀实验，黄土粗颗粒石英溶蚀分离实验；通过细颗粒单片、多片的blsl 、 irsl和post - irosl ，热释光，及粗颗粒石英的blsl的年代测定，选择适于全新世黄土的释光测年方法，并建立了渭河流域全新世黄土的年代序列。
