The 4 degrees responding mathematical model for ships established in the paper is simpler than those conventionalship hydrodynamic mathematical models. And the precision also meets the requirements.
Conventional methods are more and more difficult to adjust the modern ship degaussing system due to degaussing winding Numbers being increased continually in it.
在现代舰船消磁系统中，消磁线圈数目不断增加，已经难以用常规方法进行调整。
