摘　　要：本文讨论了空洞探测问题 :针对确定误差限问题 ,提出了若干定义 ,同时阐述了一个判定空洞存在性的定理 ,根据这个定理 ,提出了对空洞位置判定的方法 。Detection of cavity is discussed. As to the determination of detection tolerance, a number of definitions are put forward, and a theorem for the determination of the existence of cavity is introduced. On the basis of the theorem, a method for the determination of the locations of cavities is given and illustrated with examples, and it is applicable under general condition.
