On the Shape of Locus Curve of Steiner Curvature Barycenter of Piecewise Smooth Closed Convex Curve

Dong Kuizhe  
At first,this article discusses the properties such as periodicity,singulerpoints and inflection points of the locus curve of Steiner curvature barycenterof oval.By the discussion,it illustrates the general method of studying theshape of this kind of curves.Then studying of this problem of the shape oflocus curve of Steiner curvature barycenter of piecewise smooth closed convexcurve can be transformed to studying of the shape of locus curve of Steinercurvature barycenter of oval.It wprks out the shape of the locus curve ofSteiner curvatitre barycenter of ellipses in details.
