摘　　要：本文用球空间功率谱分析方法研究了ＬＢＱＳ类星体样品的成团性，讨论了ｑ０、边界效应、红移测量误差的影响，并与相关函数的结果进行了比较，认为本样品类星体是不成团的或极弱成团。This paper we analyze the clustering properties of LBQS Quasar Sample with the method of three dimensional spheroidal Power Spectrum Analysis (PSA) in SPhere,discuss the influence of q0,boundary,error of redshifts,and compare the results with the results of Correlation Function.It is found that quasars of this sample couldn't cluster or cluster very weakly.
