弱光变类星体视星等&红移关系的进一步研讨

Further discussion on relation of visual MAGNITUDE-REDSHIFT for weak variation QSOs

研究结果表明在较高的统计置信度水平上，类星体至少在低红移（Z<2）和小尺度（<10Mpc）上是成团分布的。

The statistical results show that the quasar clustering at low redshift ( Z < 2 ) and on small scale ( < 10Mpc ) has been confirmed at high statistically significant level .

近年来发现了一批Z>4的类星体，这些高红移类星体使人们对早期宇宙中的大尺度结构演化和星系形成的理论模型提出了新的观点。

A number of quasars with redshift Z > 4 have been discovered in recent years , which provide important constraints to theoretical models for the large scale structure evolution of the universe and the formation of galaxies at early time .

本文综述类星体的观测和理论研究现状，详细介绍本人在攻读博士学位期间在类星体多谱勒红移方面的研究工作。

We summarize the observational and theoretical studies of quasars , and present the results of our studies on the Doppler redshifts of quasars .

红移意味着类星体是非常非常遥远的天体，比我们观测到的最遥远的星体还要远。这个计画的目标是量取100万个星系与类星体的红移，现在已将达成目标的一半。

The redshift means that the quasars are very far away , more distant than the most distant galaxies we can see . The project is now approaching the halfway point in its goal of measuring one million galaxy and quasar redshifts .
