摘要：
We measured the abundances of as many as 35 elements in 22 metal-poor stars to examine the nucleosynthesis yields from metal-poor Type II SNe and from the r-process. We present a new trend in [Zn/Fe], confirm a universal r-process pattern for Z greater than or equal to 56, and find variations of up to 1 dex in [Y/Ba].
