宇宙尘的研究能够为探索太阳系的起源以及天体的演化提供重要的信息,所以一直是宇宙化学和天文地质学的一个活跃的研究领域。 为了鉴别宇宙尘的真伪及其来源,一个重要的方法就是测定它们的化学组成。然而,由于宇宙尘的重量一般只有几微克到上百微克,粒径大体上在几微米到几百微米,因此,普通的
The study of cosmic dust can provide important information for exploring the origin of the solar system and the evolution of celestial bodies. Therefore, it has been an active research field in cosmochemistry and astronomy. In order to identify the authenticity of cosmic dust and its source, an important method is to determine their chemical composition. However, since cosmic dust generally weighs only a few micrograms to hundreds of micrograms and the particle size is generally in the range of several micrometers to several hundred micrometers, ordinary
