太阳系形成及演化研究方法

通过对陨石的研究，说明太阳系的形成与演化历史，包括太阳星云的凝聚过程、高温加热熔融事件和低温蚀变过程，陨石母体的热变质作用、熔融分异作用以及冲击变质作用等。对太阳星云的化学组成和同位素组成不均一性、前太阳物质的存在及其意义、太阳系形成和演化的同位素绝对年龄、间隔年龄以及宇宙射线暴露年龄等进行了讨论。结合太阳系形成和演化的研究，特别对电子探针、离子探针、透射电子显微镜以及拉曼光谱等微束分析技术在该领域的应用和相关问题进行了讨论。

METHODS OF RESEARCH ON FORMATION AND EVOLUTION OF THE SOLAR NEBULA

Based on the studies of meteorites, the authors introduce the formation and evolution of the solar system, including condensation, heating and alteration in the solar nebula, thermal metamorphism, igneous fractionation and shock metamorphism in parent bodies of meteorites. Heterogeneities in chemical and isotopic compositions of the solar nebula, interstellar grains, absolute and interval isotopic ages, and cosmic ray exposure ages are also discussed. Meanwhile, the authors also discuss on the related experimental methods, especially, electron probe microanalysis, ion probe, transmission electron microscope and laser Laman spectrometer.
