| 摘 要： | 在发现类星体的方法中,最有效的４种方法是颜色方法,无缝光谱方法,射电方法和Ｘ射线方法,覆盖的波段为射电波段,光学波段和Ｘ射波段,将４种方法联合在一起,应用于４个ＵＫＳＴ天区。其目的是尽量减少选择效应,建立更完备的类星体巡天体本。从１０２天区开始,已完成了Ｘ射线选和部分光学选的分光观测工作,发现了１颗Ｂ＝１５．１的亮类星本和１个Ｓｅｙｆｅｒｔ星系对,其强Ｘ射线辐射是迄今首次观测到的。

| Abstract: | In order to reduce the selection effects and obtain highly complete samples, combined methods are used in recent quasar surveys. The MWQS (multi wavelength quasar survey) combines four selection methods (radio selection, color selection, slitless spectroscopy selection, and X ray selection) in three wavelengths (radio, optical, and X ray) to reduce the selection effects. During the MWQS program, a bright quasar RXJ 11315 1243 was discovered in field 1002 with magnitude B =15.1 and redshift z =0.09. During a program of identifying the RASS bright sources in "blank fields", it is found that the RXJ 00031-0419 is a pair of Seyfert galaxies. It is the first interacting system known with a bright X flux. |
