Prompted by previous work published in this magazine, in this article we focus on the derivation of global analytical bounds for the error function of a real argument. Using an integral representation of this function, we obtain two simple and accurate lower bounds, which complement a well-known upper bound given long ago by Pólya.

限制误差函数

受本杂志先前发表的工作的启发，在本文中，我们重点介绍实参数误差函数的全局分析界限的推导。使用该函数的积分表示，我们获得了两个简单而准确的下界，它们补充了很久以前由 Pólya 给出的众所周知的上限。
