| 摘 要： | 首先在球坐标系中导出了三度磁性体的“拟引力位”V（p）、“拟引力场”F（p）、磁位U（p）、总磁场T（p）和任意方向磁场分量（p户）等球谐级数正演通式．然后,采用（p）,F（p）和V（p）等3个球谐级数正演通式,建立了复杂条件下三度剩余磁力异常源全方位成像方法．最后,给出了“成像”理论方法体系的应用实例．

| Abstract: | In the present work, the authors have been firstly derived the general spherical harmonic expressions in the spherical coordinate system for"quasi-gravity potential" V （p）, the "quasi-gravity field" F（p）, the magnetic potential U（P）, the total magnetic field T（P）and its components in arbitrary direction n （p）. They prooed then to develop the theory and method of omndirectional imagery of 3D magnetic residual anomaly sources in the complex condition using the general spherical harmonic expression for V（P）, F（P）, n （p ）. Finely,the example of practical application of imagery imagery has been given. |
