| Abstract: | In this paper, we research the method and theory of detecting the underground weak signal metal pipeline, and according on the theory how to distribute horizontal component and vertical gradient cross - sections curve of single pipeline magnetic field and symmetry theory of magnetic Hx and △ Hx of metal pipeline creating when it is detected, and prove the method how to locate plane coordinates of weak signal metal pipeline, that is usual to detect the plane position of weak signal metal pipeline by actual project. |
