中文摘要	We investigated two pion condensed phases in the frame of two flavor Nambu-Jona-Lasinio model at finite baryon density: the homogeneous and isotropic Sarma phase and inhomogeneous and anisotropic LOFF phase. At small isospin chemical potential mu /sub I/, the Sarma state is free from the Sarma instability and magnetic instability due to the strong coupling and large enough effective quark mass. At large mu /sub I/, while the Sarma instability can be cured via fixing baryon density n/sub B/ to be nonzero, its magnetic instability implies that the LOFF state is favored than the Sarma state. In the intermediate mu /sub I/ region, the stable ground state is the Sarma state at higher n/sub B/ and LOFF state at lower n/sub B /.
