solar neighbourhood meaning in Chinese

太阳附近空间

W uma systems are very common , comprising some 95 per cent of eclipsing variables in the solar neighbourhood
相接双星的存在又十分普遍，在太阳系附近， 95的食双星都是wuma型相接双星。
On the bases of the galaxy evolution theory , we use the therotical chemical evolution model of three zone ( such as halo , thick disk and thin isk ) and multi - phase ( diffuse gas , molecular clouds , stars of both low and high mass , the remnants ) . by comparing with the observational constraints , such assurface densities , age - metallicity relation , g - dwarf metallicity distribution in the solar neighbourhood and the correlation between [ a / fe ] and [ fe / h ] , supernovae rates , infall rates . the rationality of the model is verified . based on the theory model , we calculate the abundance of neutron capture element
本文正是在银河系化学演化的基础上，利用银河系的三成分( threezone ) (即晕、厚盘和薄盘)多相( multi - phase ) (气体，分子云，大、小质量恒星以及剩余物质)的化学演化的理论模型，通过与观测约束(质量面密度、场星的年龄-金属丰度关系、太阳附近g矮星金属含量分布函数、三成份的特征量、元素的星系化学演化、超新星的爆炸率、内落速率等)的比较，来检验模型的合理性。
