摘要
本文根据二颗行星际尘的质谱(1～32a.m.u)和EDS谱,分析了它们的低原子序元素的丰度.结果表明,它们与相应的太阳系元素丰度值相近,是碳质球粒型宇宙尘,可能保留有较多大用系形成初期的信息。
In this paper we analyse the abundances of Low-Z elements in two IDPs. from their mass spectra ( mass from 1 to 32) with Secondary Ion Spectrometry, and EDS (X-Ray Energy Dispersive Spectra). The results show that the abundances are similar to those of the Solar—System. So the two IDPs are chondritic, and they may have more information of the early Solar-System.
