英文摘要：

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.
