At the end of the paper , we extend the utilities of pif and design several innovative polarization interference devices , such as broad - band polarization rotator , interleave and polarization vector integrating device . all these exploratory researches will promote the further development of pif 最后對(duì)偏振干涉濾光片用途進(jìn)行合理拓展,利用偏振光的干涉特性,設(shè)計(jì)了幾種實(shí)用的偏振器件,例如寬波段偏振旋轉(zhuǎn)器、交錯(cuò)復(fù)用器和偏振整合器等。
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。
