The aim of this paper is to study and generalize some results that related by compactness and continuity of Urysohn.S operator of two variables on a set on which a lebesgue measure is defined and using the norm that achieved some certain conditions and study uniform convergence sequence of Urysohn.S. operators that defined by functions using conver -gence In measure depending on Caratheodory condition of measurable sets and obtain similar results related by continuity and compactness conditions of optional operator that achieved Urysohn .S operator.
