摘要 利用一些概率论的有关性质及不等式,研究了有界可测函数f的Bernstein B啨zier算子B(α)n(f,x)的点态逼近速度,得到一个点态逼近速度渐近估计式. This paper uses relative theorem and unequality in the theory of probability and studies point mode approximational speed of Bernstein Bézier operator B (α) n(f,x)of the bounded and measurable function f ,then gets an estimated formula.
