flattening

The thesis contains following main parts : ( 1 ) the intrinsic flatness of disk galaxies has been statistically analyzed based on 14 , 988 disk galaxies taken from the leda database
我们的主要研究工作有： ( 1 )我们从leda数据库中选取了14 ， 988颗盘星系进行了内禀扁度的统计分析。
The results of factor analysis showed that the following three shell factors are independent , and that there are no correlations among them : shell size , shell flatness and protoconch whorl number
因子分析结果显示壳大小、壳扁度及原壳螺层数三种壳因子是相互独立的，它们之变异互不相关。
The distributions of shell flatness and protoconch whorl number are random , we could not find any notable distinction in the shell flatness of snails on surfaces of different inclinations . in a later process , using the three shell factors performed a hierarchical cluster analysis
Cathaicacavimargo种群壳扁度和原壳螺层数的分布是随机的，分析结果中未看到壳扁度事先所估计那样水平地面种群贝壳扁平，而垂直岩壁种群贝壳凸起情况。
