By the continuity of preduality map, we give some necessary and sufficientconditions of the strongly convex and very convex spaces, respectively. Usingnearly strong convexity of 𝑋, we give some equivalent conditions that everyelement in 𝑋 is strongly unique of order 𝑝, bounded strongly unique of order 𝑝, and locally strongly unique of order 𝑝.
