中文拼音 [fúdàisuān]
氟代酸
英文
fluoro acid-
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
