We apply the Maximum Entropy Method to determine valence quark distributionsof the neutron at a low scale $Q_0^2$. At the initial evolution scale $Q_0^2$,there are no sea quark and gluon distributions except for that of the threevalence quarks (udd). Using the DGLAP equations with parton-partonrecombination corrections (nonlinear effect), we obtain the neutron structurefunction $F_2^{\rm n}$ at any high scale $Q^2$. The predicted structurefunction ratio $F_2^{\rm n}$/$F_{2}^{\rm p}$ is approximatively consistent withthe world DIS data of proton and deuteron targets, if the uncertainties causedby model-dependent corrections are taken into account. Furthermore, ourobtained $F_2^{\rm n}/F_{2}^{\rm p}$ ratio basically agrees with BONuSexperimental results after considering both the contamination from the nucleonresonances around $x\gtrsim 0.4, 0.5, 0.6$ and the contribution of systematicuncertainties. The predicted $F_2^{\rm n}/F_{2}^{\rm p}$ and $u/d$ ratios underthe limit of $x\rightarrow 1$ are compared with the theoretical calculations.Finally, we check that the parton distributions of proton and neutronapproximately satisfy isospin symmetry in this work.
