摘　　要：引入了多元函数项级数的概念,给出了其收敛域及和函数的定义;通过详实的例子讨论了多元幂级数的收敛域、和函数及多元函数展开为多元幂级数的计算方法.The concept of series of functions in several variables is introduced, and its domain of convergence and sum function are defined. The techniques of computing the domain of convergence and sum function and expanding functions in several variables to power series of functions in several variables are mainly discussed by many examples.
