It is found that 1E 1207.4-5209 could be a low-mass bare strange star if itssmall radius or low altitude cyclotron formation can be identified. The ageproblems of five sources could be solved by a fossil-disk-assisted torque. Themagnetic dipole radiation dominates the evolution of PSR B1757-24 at present,and the others are in propeller (or tracking) phases.
