(dī′ĭ-lĕk′trĭk) Adjective . Muaj me lossis tsis muaj peev xwm ua hluav taws xob. Noun. Ib yam khoom siv dielectric, xws li iav lossis roj hmab.
Koj txhais li cas los ntawm dielectric nruab nrab?
Electromagnetic hauv paus ntawm microwave cua sov
Ib qhov nruab nrab lossy dielectric txhais tau tias yog a nruab nrab uas cov hluav taws xob conductivity tsis sib npaug rau xoom tsis tau nws tsis yog tus neeg xyuas pib zoo … Cov kev sib npaug yoj dav dav thiab qhov cuam tshuam tsis sib xws tau nthuav tawm hauv Kev Sib Tw 1.12 txog 1.22 yog li siv rau cov xov xwm tsis zoo.
txhais li cas los ntawm lub zog dielectric?
Dielectric zog, tseem hu ua dielectric breakdown zog (DBS), yog lub peev xwm hluav taws xob siab tshaj plaws uas cov khoom siv tuaj yeem tiv taus ua ntej cov hluav taws xob tam sim no tawg los ntawm cov khoom thiab cov khoom siv tsis yog cov khoom siv hluav taws xob ntxiv lawm.
txhais li cas los ntawm dielectric vim li cas nws thiaj li hu ua?
Dielectrics yog cov khoom siv uas tsis tso cai rau tam sim noLawv feem ntau hu ua insulators vim tias lawv yog qhov sib txawv ntawm cov conductors. Tab sis feem ntau yog thaum tib neeg hu cov insulators "dielectrics," nws yog vim hais tias lawv xav kom nyiam cov cuab yeej tshwj xeeb sib koom los ntawm tag nrho cov insulators: polarizability.
Dab tsi yog cov khoom siv dielectric muab piv txwv?
Hauv kev xyaum, feem ntau cov ntaub ntawv dielectric yog cov khoom. Piv txwv suav nrog porcelain (ceramic), mica, iav, yas, thiab cov oxides ntawm ntau yam hlauQee cov kua thiab roj tuaj yeem ua cov khoom siv hluav taws xob zoo. Cov huab cua qhuav yog ib qho zoo heev dielectric, thiab yog siv nyob rau hauv qhov sib txawv capacitors thiab qee hom kab sib kis.
