- In the future, the study on the inhomogeneity of the Galactic chemical evolution and the new observation of halo stars will give more understanding of this problem. 同时，超新星引起的星系演化的不均匀性不足以解释观测到的晕星快中子元素含量的弥散，因此这个问题还有待于更进一步研究。

- We calculate and discuss the probability to detect FGS using the chemical evolution model of Galactic halo posed by Tsujimoto et al (TSY 99) under the assumption that the first generation star has Miller Scalo form of initial mass function. 为解释这一观察现象 ;将以Tsuiimoto等人提出的银晕的化学演化模型为基础 ;假设形成第一代恒星的初始质量函数具有Miller Scalo的形式 ;从理论上预言和讨论探测第一代恒星的可能性 .

- According to the conventional hypothesis, the earliest living cells emerged as a result of chemical evolution on our planet billions of years ago in a process called abiogenesis. 根据传统的假说，最初的活细胞，肇生于数十亿年前地球上的化学演化过程，这种说法称为无生源说。
- Lithium is one of the few nuclei which are synthesized during the Big Bang, the abundancesof which are of importance for our understanding of many problems, ranging from primordialnucleosynthesis, to the chemical evolution of our Galaxy. 锂是少数几种在大爆炸中生成的元素之一，研究锂丰度对于探讨各种元素核合成理论以及星系的早期化学演化规律都具有十分重要的意义。
- Thus, this kind of secondary r-process site seems ruled out by the observations. Recently, the abundance evolution of n-capture elements in metal-poor stars play more and more important and active role in chemical evolution of theGalaxy. 由于星系r一过程元素的主要来源为大质量星secondaryr一过程(通过种子核核合成)，核合成区域内种子核和中子源主要来自恒星自身的核反应而不是来自极贫金属星形成时很低的初始丰度，由此可以解释观测到的大量极贫金属星中r过程元素的超丰;
