In this paper,we will also generalize the supercontinuous posets and s2-continuous posets and define s*2-supercontinuous posets.Then we obtain some characterization of s2-supercontinuous posets and s*2-supercontinuous posets.The main results are as follows:1)s2-set is defined and some equivalent characterizations of s2-supercontinuous posets are given.2)The relationship between s*2-supercontinuous posets and s2-supercontinuous posets is given.3)The definition of s2-C-spaces and the relationship between s2-C-spaces and s*2-supercontinuous posets are given.
