摘　　要：二元函数随着变量个数的增加,其极限计算要比一元函数极限计算复杂.本文在总结已有二元函数极限教学方法的基础之上,特别探讨了二元有理函数极限的教学方法.为二元函数极限计算的教学提供一个新的思考角度.With the increase of the number of variables,calculating the limit of binary function is more complex than that of one variable function.In this paper,the limit teaching methods of binary function are summarized.Especially based on the summaries,the limit teaching methods of binary rational function are discussed.It provides a new way of thinking for the limit teaching of binary rational function.

关 键 词：二元函数 二元有理函数 二元函数极限
