摘　　要：舰船磁场的矢量曲面积分法是磁场延拓的一种高效方法,在只能测量舰船平面磁场时,首先由平面磁场反演得到等效包络面磁场,进而利用曲面积分法延拓得到目标平面磁场。该方法较之磁体模拟法等更加方便有效。船模实验验证了该方法的有效性,具有较高的换算精度,为舰船近场磁场的换算提供了一种新的思路。The vector surface integral method is a high effective method for the continuation of ship magnetic field. When only a plane magnetic field can be gotten, based on which we can calculate the field on the equivalent enveloping surface inversely, and then the objective field can be gotten by surface integral method. Compared with the magnet simulation method, the inverse method is more efficient. The mockup experiment has indicated the validity and high calculation precision of the method, which supports a new thought for the near field conversion of the ship.
