1) thick-disk population
厚盘族
2) thick disk
厚盘
1.
Since thick disks in SO galaxies were originally detected in 1979,thick-disk compo- nents have been discovered in many disk galaxies,and there are more and more observational evidences that the thick disk in an external galaxy should be a component of the galaxy which is structurally,chemically and kinematically distinct from the thin disk of the galaxy.
自1979年以来,越来越多的观测证据表明,在许多盘状星系中普遍存在厚盘成分,它们在结构、化学组成和运动学等方面与薄盘有着明显的不同。

对太阳邻域内银河系盘星、特别是厚盘恒星年龄-金属度关系的研究进展作了较为详细的回顾和评述；说明目前对盘星是否确实存在年龄-金属度关系还存在争议，而厚盘恒星可能存在这种关系。
3) layers of thickness
