摘　　要：根据拉普拉斯第二类边界值问题的唯一性定理和舰船等效原理,提出利用包围铁磁物体的封闭曲面上的垂向磁感应强度,通过磁体模拟法推算出封闭曲面上测量点的纵向分量和横向分量的方法。该方法可避免三分量测磁仪使用不便,且造价较高的问题。通过船模实验证明,该算法直观,编程简单,计算速度较快,可以方便地应用于工程实际,对舰船磁防护的研究具有重要价值。According to a uniqueness result of solution to Laplacian＇s second boundary value problem and vessel＇s equivalence principle,a method to calculate longitudinal and transverse field was proposed by using vertical magnetic fields on the closed surface that contain magnetic object.This method would allow considerable savings in money and effort and avoid inconvenience of multi-component magnetometers.The method is shown to be theoretically feasible,then mathematic model of magnetic field calculation is established.The proposal was testes and showed good agreement with using traditional way.
