摘      要：Eclipsing binary systems are unique stellar objects to examine and understand stellar evolution and *** to these systems,the fundamental stellar parameters(mass,radius)can be obtained very *** existence of metallic-line(Am)stars in binaries is noticeably ***,the known number of Am stars in eclipsing binaries is *** Am stars in eclipsing binaries are extremely useful to deeply investigate the properties of Am stars,as eclipsing binaries are the only tool to directly derive the fundamental stellar ***,the atmospheric parameters and metallicities of such binary components could be obtained by a detailed spectroscopic ***,in this study,we present a comprehensive photometric and spectroscopic analysis of the eclipsing binary system DV Boo which has a possible Am *** fundamental stellar parameters were determined by the analysis of radial velocity and photometric light *** atmospheric parameters of both binary components of DV Boo were derived considering the disentangled *** chemical abundance analysis was carried out as *** a result,we showed that the primary component exhibits a typical Am star chemical abundance *** fundamental stellar parameters of the binary components were also obtained with an accuracy of1%for masses and3%for *** evolutionary status of DV Boo was examined utilizing the precisely obtained stellar *** age of the system was found to be 1.00±0.08 Gyr.
