摘　　要：从现有消磁电流的通电制式出发,通过求解数理方程,提出了利用小阶跃叠加法分析和计算过渡过程磁化作用的新方法,理论上定量分析研究了不同制式的消磁电流对铁磁物质的磁化效果。设计的可控电源系统实现了输出电流各种参数的可调,实验验证了过渡过程不同的电流的消磁效果和结果磁场的稳定性。结果表明,在消磁电源能量足够的条件下,过渡过程的长短对消磁效果和结果磁场稳定性的影响微不足道。Based on the mode of present degaussing current,via solving differential equation,the paper gave a new method of analyzing and calculating the magnetization effect of the current＇s transition process and made an analysis of the magnetization effect of different degaussing current in theory.The controllable power system can make the output current meet the need.Experiment was carried out to validate the degaussing effect and the magnetism stability of different degaussing current.The result showed that,the effect of transition process can be ignored in the case of the power energy is adequate.
