摘　　要：研究了广义Baskakov算子与Szász-Mirakian算子线性组合的同时逼近,并得到了Voronovskaja型的渐近展开公式以及误差估计.A simultaneous approximation for the linear combination of Generalized Baskakov and Szasz-Mirakian operators is studied. A Voronovskaja type asymptotic formula and an error estimate in the simultaneous approximation for these operators are obtained.
