本工作运用仪器中子活化分析法首次测定了我国某些不同化学群的球粒陨石非磁性相及吉林陨石高温高压实验产物非磁性相中的Fe,Mg,Al,Ca,Ni,Co,Au,Sb,Ir,Cr,Mn,Zn,Ti,V,Na,Sm,Lu,Yb,Hf,Sc,La,Eu和Se等23个元素的含量。在球粒陨石非磁性相中,亲铁元素Ir,Ni,Co,Au随H→L→LL群有增 In this work, the neutron activation analysis method was used to measure the Fe, Mg, Al, Ca, Ni, Co and Au in the non-magnetic phase of the non-magnetic phase of the high temperature and high pressure products of Jilin meteorite , Sb, Ir, Cr, Mn, Zn, Ti, V, Na, Sm, Lu, Yb, Hf, Sc, La, Eu and Se. In non-magnetic phase of chondrite, the contents of Ir, Ni, Co and Au are increased with H → L → LL groups
