| Abstract: | In this paper, a kind of generalized Bernstein type operators of two variables on simplex is constructed, a necessary and sufficient condition of uniform convergence by them is obtained, and the degree of approximation is characterized by two-order modulus of continuity. |

| Keywords: | Bernstein operator approximation modulus of continuity |
