space harmonics meaning in English

空间谐波

The slow - wave characteristics neglecting and taking account of space harmonics ( sh ) for periodically iris - loaded confocal elliptical waveguides are analysed , and the dispersion equation and the mean coupling impedance of this structure are obtained by
分析了周期膜片加载共焦椭圆波导,在考虑空间谐波和不考虑空间谐波两种情况下的慢波特性。应用场匹配方法得到这种结构的色散方程和平均耦合阻抗。
This model not only reckons in the effects of the space distribution and the connection pattern of the windings , the position of the short circuit point and the space harmonics of the gap magnetic field , but also takes into account the pole geometry , slot effects , saturation and eddy current in the rotor
该模型不仅能考虑绕组的分布与联接方式、故障的空间位置、气隙磁场的空间谐波，还能细致地考虑磁极形状、铁芯的饱和和涡流等因素。
