Isotopic yields in the velocity space for intermediate mass
fragments have been measured for ^112Sn+^112Sn, ^112Sn+^124Sn,
^124Sn+^112Sn and ^124Sn+^124Sn peripheral collisions at E/A=50
MeV. Comparison of the intermediate mass fragments yields
from different reactions with rapidity cut suggests that
isospin equilibrium is not achieved. An isospin transport
ratio Ri is construct by using isospin sensitive
observables, such as isoscaling parameters and mirror nuclei
ratios. This isospin transport ratio allows a quantitative
analysis of the isospin transportation and assessment the
transport rate. The density dependence of the asymmetry term
of the nuclear equation of state is investigated by
comparing the isospin transport ratio Ri obtained from
experiment data and theoretical calculation.
