Separation of carrier phase of primordial noble gas component trapped in primitive chondrites with ultra-high centrifugal force

用盐酸和氢氟酸处理原始碳质球粒陨石，得到碳质残渣。用超高离心分离机对残渣进行分离，得到两个馏分。对这些馏分进行了惰性气体同位素测量，在较重的馏分中检测到极高浓度的惰性气体。

A primitive carbonaceous chondrite was treated by hydrochloric acid and hydro fluoric acid and a carbonaceous residue was obtained. The residue was separated with an ultra-high centrifugation system and two fractions were obtained. Noble gas isotopic measurement was conducted for the fractions and extremely high concentrations of noble gases were detected for the heavier fraction.
