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
本文通過渭河流域全新世黃土的光曬退實驗，地表黃土樣品的d _ e值測定，細顆粒單片的預熱、反常衰退、紅外暴露實驗，說明釋光測年在全新世黃土中應用的可行性及單片再生劑量法（ sar ）在黃土細顆粒中的適用性；為了從黃土中分離出足夠的粗顆粒，進行了純石英和長石的氫氟酸（ hf ）和氟硅酸（ h _ 2sif _ 6 ）溶蝕實驗，黃土粗顆粒石英溶蝕分離實驗；通過細顆粒單片、多片的blsl 、 irsl和post - irosl ，熱釋光，及粗顆粒石英的blsl的年代測定，選擇適于全新世黃土的釋光測年方法，並建立了渭河流域全新世黃土的年代序列。 -
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
摘要對氟硅酸提碘過程的氧化劑進行選擇研究，結果表明，對碘回收率而言氧化劑b較好。 -
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
溶蝕實驗表明，用40 hf溶蝕40min對石英的損失太大，不適合黃土中石英的分離。用30氟硅酸（ 20ml冶）溶蝕約6天，分離黃土中的石英顆粒，既可以溶蝕掉長石顆粒，又對石英的損失較小。
