    Kev parameter

    Undoped YVO 4 siv lead ua yog qhov tshiab zoo tshaj plaws birefringence kho qhov muag siv lead ua thiab siv dav hauv ntau cov nqaj hlau tsis nyob rau online_orderings vim nws qhov loj birefringence. Nws tseem muaj lub zog zoo thiab lub zog mechnical tshaj thers birefringent muaju, cov khoom zoo ua rau YVO4 tseem ceeb heev birefringence optical khoom siv thiab siv dav hauv opto-electronic tshawb nrhiav, kev txhim kho thiab kev lag luam. Piv txwv li, kev sib txuas lus kho qhov muag xav tau ntau qhov ntau ntawm cov khoom tsis tau tso cai ntawm YVO4, xws li fiber ntau optical isolators, lub voj voog, nqaj hluav taws xob, Glan polarizers thiab lwm cov khoom ua polarizing.

    Nta:

    Nws muaj qhov kis tau zoo nyob rau hauv qhov dav dav ntawm qhov pom ntawm infrared.
    Nws muaj qhov ntsuas ua kom zoo siab thiab qhov birefringence sib txawv.
    Piv nrog rau lwm cov teeb meem birefringence muaju, YVO4 muaj ntau dua. qhov ua kom tawv, cov cuab yeej ua kom zoo dua qub, thiab cov dej tsis ua haujlwm zoo dua li calcite (CaCO3 ib leeg siv lead ua).
    As Ua tau yooj yim los ua cov loj loj, zoo siab siv lead ua ntawm tus nqi qis dua Rutile (TiO2 ib leeg siv lead ua).
