英文摘要	By considering the general relativity effect, we calculated the dipolar toroidal magnetic field decay rates and investigated the L-X - L-rot relationship of 22 magnetars with soft X-ray luminosities. It is found that, for magnetars with L-X < L-rot, their observed soft X-ray emissions may come from the rotational energy loss rate, or from magnetosphere flow, and/or from particle wind heating, while for magnetars with L-X > L-rot, the Ohmic decay of crustal toroidal magnetic fields can provide their observed isotropic soft X-ray luminosities and maintain high thermal temperatures.
