| 摘 要： | 本文提出用有限元法和边界元法相结合解复杂条件下的磁法勘探正问题.在磁介质区中使用有限元法,在外围空间使用边界元法,这样,可完全保留有限元法解题能力强的优点,又可简化外区的离散处理,提高效率和计算精度.

| Abstract: | In this paper it is suggested to solve the direct problem of magnetic prospecting under complicated conditions by coupling finite element method and boundary element method. While finite element method is used in the magnetic medium, boundary element is used in the exterior nonmagnetic space. This treatment enables the solution to simplify the discrete treatment in the exterior space and to improve efficiency and computed accuracy in addition to maintaining the advantage of finite, element method. |
