抄録	Let Γ be a chart with at most two crossings. In this paper, we show that if Γ is a 2-minimal generalized n-chart with n≥5, then Γ contains at least 4n−10 black vertices. And we show that if the closure of the surface braid represented by Γ is a disjoint union of spheres, then Γ is a ribbon chart. Hence the closure is a ribbon surface.
