In t.e present.paper, a mult.-linearit. met.od is used t. address t.e nonlinear slip c.nt.ol equat.on for t.e hydrodynamic.analysis of a t.o-dimensional （2-D） slip gap flow. Numeric.l analysis of a finit. lengt. slider bearing wit. wall slip shows t.at.t.e surfac. limit.ng shear st.ess exert. c.mplic.t.d influenc.s on t.e hydrodynamic.behavior of t.e gap flow. If t.e slip oc.urs at.eit.er t.e st.t.onary surfac. or t.e moving surfac. （espec.ally at.t.e st.t.onary surfac.）, t.ere is a t.ansit.on point.in t.e init.al limit.ng shear st.ess for t.e proport.onal c.effic.ent.t. affec.0}t.e hydrodynamic.load support.in t.o opposit. ways： it.inc.eases t.e hydrodynamic.load support.at.higher init.al limit.ng shear st.esses, but.dec.eases t.e hydrodynamic.load support.at.lower init.al limit.ng shear st.esses. If t.e slip oc.urs at.t.e moving surfac. only, no fluid pressure is generat.d in t.e c.se of null init.al limit.ng shear st.ess. If t.e slip oc.urs at.bot. t.e surfac.s wit. t.e same slip propert., t.e hydrodynamic.load support.goes off aft.r a c.it.c.l sliding speed is reac.ed. A small init.al limit.ng shear st.ess and a small proport.onalit. c.effic.ent.always give rise t. a low fric.0}on drag.
