This　paper　presents　an　iterative　scheme　for　solving　nonline　ar　equations.　We　establish　a　new　rational　approximation　model　with　linear　numerator　and　denominator　which　has　generalizes　the　local　linear　model.　We　then　employ　the　new　approximation　for　nonlinear　equations　and　propose　an　improved　Newton＇s　method　to　solve　it.　The　new　method　revises　the　Jacobian　matrix　by　a　rank　one　matrix　each　iteration　and　obtains　the　quadratic　convergence　property.　The　numerical　performance　and　comparison　show　that　the　proposed　method　is　efficient.
