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(diǎn)到面、由淺入深的方式,以“場(chǎng)”這個(gè)重要概念作為核心,分別對(duì)電荷、電流間的相互作用,現(xiàn)代電磁場(chǎng)理論,電磁場(chǎng)矢勢(shì)物質(zhì)性這幾個(gè)方面進(jìn)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(chǎng)中的相對(duì)論運(yùn)動(dòng)規(guī)律。三、討論了在均勻電場(chǎng)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(chǎng)強(qiáng)方向與外電場(chǎng)方向并非嚴(yán)格相反,只有當(dāng)外電場(chǎng)與電介質(zhì)橢球的某一主軸平行或者當(dāng)橢球體三半軸的大小都相等時(shí),極化場(chǎng)強(qiáng)方向與外電場(chǎng)方向才嚴(yán)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?dú)v史意義的a - b效應(yīng), a - b效應(yīng)揭示了兩點(diǎn)物理觀念的變革:一是電磁矢勢(shì)有物理效應(yīng)。二是在無(wú)場(chǎng)強(qiáng)但有磁矢勢(shì)( b = 0 , a 0 )的區(qū)域,波函數(shù)的相位因子與其運(yùn)動(dòng)空間結(jié)構(gòu)有關(guān)。 a - b效應(yīng)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(guò)a的環(huán)路積分,才能對(duì)電磁場(chǎng)的作用做出完全準(zhǔn)確的描述。
