According to structure features, parallel plane field and axisymmetrical field were used in approximate calculations of core and yoke of the valve respectively.
根据电磁阀的结构特点，将磁芯和磁轭分别按平行平面场和轴对称场近似处理。
This method may possibly be used to estimate influence of high order harmonic field on hysteresis loss to optimize the design of deflection yoke ring and to develop energy saving ferrite materials.
该方法适用于估测高次谐波场对磁滞损耗的影响，降低能量损耗的偏转系统磁芯结构的优化，磁性材料的选择等。
The lifting power of the yoke was not relative to the magnetic field composed in the workpiece tested, so it could not reflect the magnetizing power of the yoke.
该磁化装置的提升力与其在工件中产生的合成磁场无对应关系，因此不能反映对工件的磁化能力。
