用法和例句

Redshift Estimation of Galaxy Spectra Based on Similarity Measure;

基于相似性度量的星系光谱红移估计

The effect of the homogeneous collisionless particles of dark matter on the gravitational field of a galaxy, whose mass density will fall exponentially with radius, is considered in the linear and successive approximations.

本文用线性近似法和选代法研究均匀无碰撞暗物质粒子对质量密度按指数律下降分布的星系引力场的影响，导出了在无碰撞暗物质粒子背景下星系引力场的引力分布。

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。

Populating galaxies in dark matter halos;

暗物质晕中星系的配置(英文)

By comparing the physical parameters of cluster and field galaxies,such as concentration index,specific star formation rate,stellar mass,and metallicity,the star formation properties of galaxies within different gravitational environments are studied.

通过对团星系和场星系的聚度参数、特征恒星形成率、星系中包含的恒星质量、金属丰度等物理参量的比较,研究了处在不同引力环境中星系的恒星形成性质。

The luminosity-metallicity (L-Z) relation ( stellar mass-metallicity, mass-Z, relation) is one of the fundamental parameters of galaxies, and can trace the assembly history of metals and stellar masses in the galaxies.

金属丰度与星系光度是星系的重要特征参量,研究它们之间的关系有助于理解星系中恒星质量与金属成分的累积过程。
