场星系 meaning in Chinese

field galaxy

( 4 ) two methods are applied in the sv calculation for the sample of 220 field galaxies that are strictly selected from the photometric atlas of northern bright galaxies in order to analyze the sv orientation distribution of the field galaxies in our sample
( 4 )从北天亮星系星表严格挑选了220个场星系作为样本，我们运用两种处理方法处理了场星系旋转矢量分布情况。 # #原图像不清
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 . we also statistically studied the intrinsic flatness of the disk galaxies
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。
