摘　　要：通过数值处理和计算机模拟，得出一种排布方式的消磁线圈对坦克磁场的影响效应分布，即当消磁线圈为均匀密排情形时，线圈内部为匀强磁场，方向沿通电线圈的轴向，且与环形电流呈右手螺旋关系；线圈外部为磁偶极子场，该场会随着与线圈中心距离的增大而迅速减小。数值模拟的结果可为封闭型军事装备表层安装消磁线圈提供参考；通过分析消磁线圈附加磁场的特点为装备磁防护理论提供一些支持。A kind of arrangement pattern of degaussing coils＇ influential effects distribution on tank＇s magnetic field is obtained by numerical emulation. It is an evenly-distributed magnetic field along the axis of degaussing coils, and it is a right-hand spiral relationship between the magnetic field＇s direction and the encircling electric current＇s direction. It is an even-poles magnetic field outside the degaussing coils which diminishes rapidly with the distance＇s increase. With the emulation results some suggestions can be provided for installing degaussing coils on close military equipment surface layer, some theoretical supports are given for equipment magnetic safeguard by analyzing the features of the attached magnetic field of degaussing coils.
