Abstract: A modified Lupas-Baskakov integral operator, which compounds Lupas operator and Baskakov operator, is introduced in this paper. By analyzing and researching the properties of the modified Lupas- Baskakov integral operators, the paperobtains theVonorovskya asymptotic formula, establishes the saturated order and trifle set of the modified Lupas-Baskakov integral operators, and then sets up the saturation theorem for this kind of operators.
