主　　题：Einstein-Maxwell-scalar theory black hole accretion disk 

摘      要：In this study,we explore the properties of a non-rotating black hole in the Einstein-Maxwell-scalar(EMS)theory and investigate the luminosity of the accretion disk surrounding *** determine all the orbital parameters of particles in the accretion disk,including the radius of the innermost stable circular orbit(ISCO)with angular velocity,angular momentum,and ***,we study the radiative efficiency for different values of black hole ***,we analyze the flux,differential luminosity,and temperature of the accretion disk.
