Abstract We discuss the moment analysis method for the 0++ and 2++ coupling mode of fJ(1710) for incomplete phase space in the radiative decay J/ψ → γK+K-, and give a new formulation of analyzing the fJ(1710) structure for the Beijing Spectrometer detector at the Beijing Electron-Positron Collider. The incomplete detection phase space results in a significant effect on the moment analysis.
