1. When the isotropic waveguide is under the isotropic disturbances , the coupling term due to polarization , which is presented in the coupled - mode theory of the wei - ping huang , is n ' t included in this rigorous vectorial coupled - mode theory , exactly , the rigorous vectorial cmt does n ' t contain the coupling term due to polarization which is include in the scalar coupled - mode theory because this term is counteracted with the other coupling term neglected under weakly guiding approximation . as for anisotropic disturbances , we get the coupled - mode equations with arbitrary dielectric tensors . from them , we obtain the coupled - mode equations of the slowly varying term c ( z ) which is more simplicity
   當(dāng)受到各向同性微擾時(shí)，我們發(fā)現(xiàn)嚴(yán)格的矢量理論所得到的耦合系數(shù)表達(dá)式中并不包括wei - pinghuang的理論中的偏振耦合項(xiàng)，更確切的說，偏振耦合項(xiàng)正好與因弱導(dǎo)近似而忽略的項(xiàng)相抵消，這就是標(biāo)量理論所得到結(jié)果(有偏振耦合項(xiàng))與矢量理論在標(biāo)量近似下的結(jié)果(不含偏振耦合項(xiàng))不一致的原因所在；當(dāng)各向異性微擾時(shí)，我們得到了包含微擾介電張量各個(gè)分量的橫電磁場耦合波方程，討論了微擾介電張量各個(gè)分量對耦合的影響，而且從橫電磁場耦合波方程出發(fā)得到了形式更加簡單的只含有橫電場系數(shù)的緩變分量c _ ( z )的耦合波方程和耦合系數(shù)表達(dá)式，并以弱導(dǎo)近似下的單模光纖兩正交偏振模耦合為例對耦合系數(shù)在不同條件下的取舍做了定性的分析。
2. It's difficult to find scalar coupling in a sentence. 用scalar coupling造句挺難的
