Statistical Tests on the Spatial Orientation of the Field Galaxies in the Local Supercluster;
本超星系团中场星系旋转矢量分布的统计检验
This thesis mainly concentrates on the orientations of the spin vectors (SVs) with different samples of the field galaxies in the Local Supercluster (LSC) and of the galaxies in the Virgo Cluster, with the context of the origin and formation of galaxies and clusters.
本文主要对本超星系团中的场星系、不同样本来源的Virgo团成员星系的旋转矢量方向分布情况进行统计分析,以期寻找星系或星系团等宇宙大尺度结构的形成和起源信息,并给已有的或新的星系或星系团形成和起源理论提供观测依据和实验佐证。
Analysis on the Features of Superstar and Founder Apabi Digital Libraries;
超星和方正Apabi两种数字图书馆的特点分析
They are the Superstar, Shusheng; and Founder Apabi.
目前国内大型的电子图书系统有三家,它们是超星、书生之家和方正Apabi,本文主要从这三家电子图书所覆盖的学科领域和收藏数量、数据处理、价格、服务功能等多个方面,进行详细的比较研究,以期对三大电子图书加深了解,为学校和企事业单位采购电子图书提供参考。
According to"superstar"digital situation of library,introduce"superstar"digital obvious advantage of library and bring to peoples modern study and life great and convenient.
根据“超星”数字图书馆的情况,介绍“超星”数字图书馆的明显优势和给人们现代学习生活带来的极大方便。
The Method of Conversion of File Format in Using Superstar Ebooks;
自从超星图书逐步推广后,我们发现其PDG格式的使用和管理很不方便,又由于超星公司对PDG文件做了诸多限制,所以文件格式的转换也很难处理。
As a kind of compact star systems,globular clusters are very old ones with ages of older than 10~(10)years,which are different from another kind of young compact clusters, super star clusters(SSC)or massive youn.
老年球状星团和年轻的超星团是两类不同性质的致密星团,观测表明它们都表现出某种程度的质量分层效应。
