摘　　要：物理探测中通过测试数据 u n Ω =g来确定区域的形状是一个具有挑战性的问题。给出三维情况下的算法和数值模拟 ,并给出三维的算例 ,图形和表格 ,以表明算法的可行性和有效性。In physical detection of mine, the shape of an unknown domain is often reconstructed by measured data i.e. un Ω =g. It is a challenging problem. numerical simulation in 3 D is discussed. The algorithm is given. At last, some examples of 3 D are given, particularly, figures and tables of examples show that this algorithm is efficient and successed.
