| 摘 要： | 在某些浅水区域中, 常有大量工程障碍, 如磁性柱状体。依据磁性柱状体的特点, 从顺轴磁化无限延深柱状磁性体这一简化数学模型的磁场分析入手, 进而对更近实际的顺轴磁化有限延深柱状磁性体的磁场及其梯度场的分布规律进行讨论, 并据此提出了采用水平磁梯度测量法对磁性柱状体磁特性实施探测的可取途径。

| Abstract: | There exist large quantities of engineering obstacles such as magnetic pole in some shallow water areas. In the light of the characteristics of magnetic pole, this paper, staffing with an analysis of the magnetic field of the simplified mathematical model for the direct axis magnetized infinite extension columnar body, deals with the distribution regularity of the magnetic field and gradient field of the direct axis magnetized finite extension columnar magnetic body which is closer to the actual situation. On such a basis, it is suggested that the method of horizontal magnetic gradient measurement could be adopted to detect magnetic characteristics of magnetic pole. |
