摘要：

Short-lived radionuclides are radioactive elements with half-lives <= 100 Myr. They have all decayed away from their initial abundances, but their presence in the early Solar System could be inferred from radiogenic excesses of daughter products in meteoritic components. A detailed understanding of the initial abundance and distribution of short-lived radionuclides can shed light on the formation condition and immediate astrophysical environment of the early Solar System.
