设是一个内部有二维裂纹的三维物体。它将表明，裂纹的位置和大小是唯一确定的边界上的测量。此外，裂纹的物理行为将被识别。我们的模型如下。在物体内部，除了裂纹外，我们假定有一个谐振势。将在其上实现电流通量，并且我们测量那里的电压电势。
Let be a three-dimensional body with an interior two-dimensional crack . It will be shown that the location and size of the crack is uniquely determined by measurements on the boundary of . Moreover, the physical behaviour of the crack will be identified. Our model is the following. Inside the body, with the exception of the crack, we assume a harmonic potential. A current flux will be implemented on and we measure the voltage potential there.
