修正q-Phillips 算子的逼近性质
Approximation properties of modified q-Phillips operators

引进一类修正q-Phillips算子，并研究该算子列的一些逼近性质. 得到算子列的一个Korovkin 型收敛定理，给出了算子列收敛速度的估计和一个Voronovskaja 型结果.
In this paper，a kind of modified q-Phillips operators is introduced，some approximate properties of the operators are studied. A convergence theorem of Korovkin type is established. Also，an estimate for the rate of convergence and a Voronovskaja-type result are given
