The isoscaling behaviour is investigated in a frame of isospin-dependent quantum molecular dynamics models. The isotopic yields ratio Y 2 / Y 1 for reactions 48 Ca+ 48 Ca and 40 Ca+ 40 Ca at different entrance channels are simulated and presented, the relationship between the isoscaling parameter and the entrance channel is analysed, the results show that α and β reduce with the rise of incident energies and increase with the impact parameter b , which can be attributed to the temperature varying of the pre-fragments in different entrance channels. The relation of α and symmetry-term coefficient C sym reveals that the chemical potential difference Δμ is sensitive to the symmetry-term coefficient C sym , and raises with the increasing C sym .
