英文摘要	We present optical identification results for four ROSAT PSPC soft X-ray companions of Mrk 231 based on the deep BATC 6660 Angstrom-band image and the optical spectra obtained by the 60/90 cm Schmidt telescope and the 2.16 m telescope at the Xinglong Station, NAOC. Three optical counterparts are quasars with redshifts z > 1 and the remaining X-ray source is probably a background galaxy cluster. Therefore, none of these soft X-ray companions are physically connected with the central X-ray source Mrk 231. Incorporating the previous results of Arp 220 and Mrk 273 (Xia et al. 1998, 1999), we suggest that the apparent soft X-ray associations with ULIRGs are chance coincidence in most cases.
