Thereafter, a new kind of compound rectangular coil is proposed to apply to acfm . after its electromagnetic field distribution is analyzed in detail, the measurement scale is given . all the study can be used as the academic base to study the acfm syste m further 在此基础上,本文提出将一种新型复合矩形线圈应用到交变磁场测量技术中,并重点研究了复合矩形线圈激励下电磁场分布特性,讨论了缺陷检测的数值范围。
As the single rectangular coil is the routine induction probe, the system is simulated based on the theory of a-v-a . the perfect induction field is studied . the corresponding relations between the slots and the field are also analyzed, as well as the measurement scale is given here )描述下交变磁场测量技术单矩形线圈激励形式下的数值仿真模型,从场量检测的角度出发,分析了无缺陷情况下该系统的电磁场分布特性,以及有缺陷情况下缺陷与场分布的对应关系以及缺陷检测的数值范围。
