Abstract: In the framework of the modified Fisher model， correlations between the symmetryenergy coefficient in semiclassical mass formula to temperature (asym/T) and the isobaric yield ratio in Heavyion collisions are established. asym/Tof neutronrich fragments are extracted using these correlations. It is found that the Coulombenergy term has little effect on asym/T of fragments， while the reference isobars adopted have great influence on the extracted a sym/T of fragments.
