| 摘 要： | 多重幂级数是讨论函数的重要工具，但其性质并非完全与简单幂级数相同。本文指出了Г．Ｍ菲赫金哥茨著《微积分学教程》关于二重害虫级数收敛区域讨论中的一个错误引理。并修改证明了此结论，进而在此基础上指出对后续内容的影响。

| Abstract: | Power series of several variables is a important tool to discuss function, but its property is different with simple power series. In this paper, we found a wrong lemma on power series of several variables, and we modified it. |
