摘要：

We propose that some neutron stars in low-mass x-ray binaries can accrete sufficient mass to undergo a phase transition to become strange stars. The energy released per conversion event satisfies the requirements of cosmological gamma-ray bursts, and the Lorentz factor of the resultant expanding fireball may exceed 5 x 10(3) because the strange star has very low baryon contamination. The model burst rate is consistent with observations.
