摘　　要：提出了广义ＨＰ±｛λｊ｝类函数．通过这类函数研究了双正交有理函数系的带权平均逼近。The generalized functions of H P ±{λ j} type are proposed. By using those functions, the weighted mean approximation of biorthogonal rational function system is studied, and we obtain the theorem of the weighted mean approximation of biorthogonal rational fuction system.
