摘      要：We studied the optical band periodic variability of 1823+568 using the Jurkevich method,the Lomb-Scargle periodogram and the REDFIT38 software,and found evidence of quasi-periodic *** unprecedented variability with period P=283^(+17)_(-13) days was identified by three different analysis *** quasi-periodic variability most likely results from nonballistic helical jet motion driven by the orbital motion in a binary black hole *** the light-travel time effect,the real physical period is P_(d)=67.1 ***,we estimated that the primary black hole mass is M■1.92×10^(9) M_(⊙)to 3.43×10^(9) M_(⊙).
