文摘Let M be a compact convex hypersurface of class C2, which is assumed to bound a nonempty convex body K in the Euclidean space Rn and H be the mean curvature of M. We obtain a lower bound of the total square of mean curvature fM H2dA The bound is the Minkowski quermassintegral of the convex body K. The total square of mean curvature attains the lower bound when M is an （n - 1）-sphere.
