摘　　要：消磁船消磁时对舰船的磁场测量多采用点测方式,实际测量点与理想测量点之间存在位置误差.为使该误差不影响消磁质量,探头应不超出某一误差球范围.文中提出了一种用于消磁船磁场测量的误差球评估方法,并利用某型船模的实验室测量数据,计算了其误差球半径,从而为确定消磁船上配置的磁探头应满足的抗水流冲击能力指标提供了理论依据.When a degaussing ship deperms a ship, the measurements of the magnetic field are usually made point by point. Generally there exits an error between the real measurement point and the ideal one. In order not to influence the deperming quality, the magnetic sensor should not be out of some error ball. A method of error ball evaluation is given for magnetic field measurements of a degaussing ship. Using the measured data of a ship mock in laboratory, the radius of its error ball is calculated. It provides a theoretical basis for deciding what kind of requirements the magnetic sensor should meet to counter the current impact.
