Moreover, the turbulent stress also causes the convection the mixing action to strengthen, so elements abundance of the stellar interior and surface are all changed.
另外，湍流应力还使对流的混合作用加强，从而导致恒星内部及表面的各元素丰度都发生改变。
Note3: Actinide abundance ratios may be applied to measurements of stellar ages.
注3：锕充足比率可用于测量恒星的年龄。
Analysis about the abundance in different stellar populations is a very important subject in study of the structure and chemical evolution of the Galaxy.
恒星元素丰度是探讨银河系化学演化的重要探针，分析不同星族成分的元素丰度是研究银河系结构和化学演化的重要课题。
