The　nonlinear　optic　characteristics　of　an　intense　laser　pulse　propagating　in　partially　stripped　plasmas　are　investigated　analytically.　The　phase　and　group　velocity　of　the　laser　pulse　propagation　as　well　a　5　the　three　general　expressionsgoverning　the　nonlinear　optic　behavior,　based　on　the　photon　number　conservation,　are　obtained　by　considering　the　partially　stripped　plasma　as　a　nonlinear　optic　medium.　The　numerical　result　shows　that　the　presence　of　the　bound　electrons　in　partially　stripped　plasma　can　significantly　change　the　propagating　property　of　the　intense　laser　pulse.
