The method has three features as follows:(1)fully considering the effect of spaceharmonic magnetic field;
这种算法具有三个特点：（1）充分考虑空间谐波的磁场作用。
2
The spaceharmonic expansion technique is used for analyzing the 3d magnetic fields of the deflection yoke.
研究了显像管等器件中偏转线圈三维磁场的空间谐波展开技术及其计算。
3
The calculation considers the spaceharmonic magnetic field, and has no limits of connection forms of windings. The inductance calculated in this method are quite accurate.
