引进二元广义 Baskakov 算子逼近的余项定义，并针对三类不同函数的余项给出了的三种估计形式，推广了一元广义 Baskakov 算子逼近的余项估计结果，同时改进了二元广义 Baskakov 算子逼近度的定理。
引進二元廣義 Baskakov 算子逼近的餘項定義，併針對三類不同函數的餘項給齣瞭的三種估計形式，推廣瞭一元廣義 Baskakov 算子逼近的餘項估計結果，同時改進瞭二元廣義 Baskakov 算子逼近度的定理。

The definition of approximated remainders with two-dimensional generalized Baskakov operators is introduced , the remainders are discussed for three kinds of functions , and three forms of estimated remainders are obtained . The results of remainder estimation of approximation by generalized Baskakov operator are extended , and the theorems of approximation degree of two-dimensional generalized Baskakov operators are improved , so that the results become even more precisely .
