摘　　要：利用扩展乘数法建立了若干多项式算子逼近任意无界连续函数的收敛性定理，给出 了具有一般性的结论，从而推广了前人的许多重要定理．By using the method of multiplier-enlargement, this paper established many convergence theorems of polynomial operators to approximate any unbounded continuous functions, and gave general conclusions, therefore generalized many important theorems of L. C. Hsu and R. H. Wang.
