本文中介绍了对阿伦德(Allende)陨石中4个壳层球粒的核部和壳部所做的仪器中子活化分析和放射化学中子活化分析工作,测定了8个(4对)样品的25个痕量元素。分析结果表明,元素在球粒核部和壳部具有不同的分布特征,这一结果为研究球粒的成因提供了进一步依据。
This article describes instrumental neutron activation analysis and radiochemical neutron activation analysis of the four shell pellets in Allende meteorites. Eight (4 pairs) 25 trace elements of the sample. The results show that the elements have different distributions in the nucleus and shell of the pellet, and this result provides a further basis for the study of the genesis of the pellet.
