摘　　要：In this work,based on the liquid-drop model and considering the shell correction,we propose a simple formula to calculate the released energy of proton radioactivity(Q_(p)).The parameters of this formula are obtained by fitting the experimental data of 29 nuclei with proton radioactivity from ground state.The standard deviation between the theoretical values and experimental ones is only 0.157 Me V.In addition,we extend this formula to calculate 51 proton radioactivity candidates in region 51≤Z≤83 taken from the latest evaluated atomic mass table AME2016 and compared with the Q_(p)calculated by WS4 and HFB-29.The calculated results indicate that the evaluation ability of this formula for Q_(p)is inferior to WS4 while better than HFB-29.
