| 摘 要： | 中梯装置由于采集的数据量有限,通常视为面积性方法而不作定量解释。以中梯装置椭球异常体的激电异常理论为基础,采用坐标旋转、椭圆积分等技术手段推导了水平大地均匀场中任意形态椭球体电场、视极化率和视电阻率解析计算公式,编写了相应程序,为下一步中梯激电实测数据定量反演奠定了基础。 |
| 关 键 词： | 椭球体 中间梯度法 激电 异常 |

| Abstract: | Intermediate gradient array due to the limited amount of data, usually regarded as an area method without quantitative interpretation. A formula of the electric potential, apparent induced polarizability and apparent resistivity caused by any ellipsoid anomaly with arbitrary shape are derived based on the IP theory by means of rotating coordinate system and elliptic integrals. Therefore, the solid foundation is established for the next step of anomalous quantitative inversion correspondingly. |
| Keywords: | Ellipsoid Central Gradient Array IP Method Anomalous Characteristic |
