The direction of the electric field vector is indicated in each picture . 每張照片上都標出了電場矢量的方向。
When the end of the electric field vector travels in an ellipse, the light is elliptically polarized . 電場矢量的末端沿一橢圓移動的光叫橢圓偏振光。
Complex field vector 復數(shù)場矢量
Coupled field vector 耦合場矢量
Irrotational and solenoidal split problem on a dyadic green ' s function of the field vector 一類場矢量的并矢格林函數(shù)無旋和無散分解問題
What modern electromagnetic field theory studies is the electromagnetism interaction between an electromagnetic wave that has the quantum characteristic and the matter that has the classic characteristic . we re - know the quality of substance of the electromagnetic field vector a from the theory that the electromagnetic field is the 總之,本文采用從點到面、由淺入深的方式,以“場”這個重要概念作為核心,分別對電荷、電流間的相互作用,現(xiàn)代電磁場理論,電磁場矢勢物質(zhì)性這幾個方面進行討論、分析。
3 . the solution for the distribution of potential internal the dielectric ellipsoid has been obtained by means of ellipsoidal coordinates , and has obtainted the expression of the polarization field strength in the dielectric ellipsoid , calculated the included angle value of polarization vector and the external field vector , making programe to compute to get the relation shetch between the included angle value of polarization vector and the external field vector and we have discussed the result and hold that the direction of polarization field strength with that of the external field don ’ t always strict antiparallel 二、討論了帶電粒子在均勻電磁場中的相對論運動規(guī)律。三、討論了在均勻電場中電介質(zhì)橢球體的極化規(guī)律。證明了電介質(zhì)橢球內(nèi)的極化場強方向與外電場方向并非嚴格相反,只有當外電場與電介質(zhì)橢球的某一主軸平行或者當橢球體三半軸的大小都相等時,極化場強方向與外電場方向才嚴格相反。
In this article , introduce the important meanings of a - b effect , first is a have physics factors , second is wave function phase factor is connected with geometrical factor in ( b = 0 , a 0 ) , through a - b effect , we know : electromagnetic field vector e , b is local quantity , electromagnetic potential a , is global quantity , adding a , description and by the way of loop integral , electromagnetic field " effect is completely descripted 本文介紹了有重要歷史意義的a - b效應, a - b效應揭示了兩點物理觀念的變革:一是電磁矢勢有物理效應。二是在無場強但有磁矢勢( b = 0 , a 0 )的區(qū)域,波函數(shù)的相位因子與其運動空間結(jié)構(gòu)有關。 a - b效應顯示; e 、 b是局域量, a 、是總體量,只有加入a 、之后的描述,并通過a的環(huán)路積分,才能對電磁場的作用做出完全準確的描述。
