Both nonreciprocal birefringent effect and variable polarization effect of microwave ferrite in the symmetrical four-pole magnetized field are discussed in the light of coupling-wave theory.
本文用耦合波理论处理了对称四磁极磁化情况下，微波铁氧体的非互易双折射效应和变极化效应。

Then the selections of phase number, winding connection, pole number and number of branches in parallel are optimized according to the SRM's symmetry and order of force wave.
接着从对称性、力波阶数等角度研究了SR 电机相数及绕组连接方式、极数、并联支路数的选择问题。

The particular approach considered is that of collocated, PD feedback wave control combined with modal control designed using pole placement.
