Dej muaj qhov dielectric siab tas li vim cov dej molecule muaj lub sijhawm dipole thiab yog li nws tuaj yeem ua polarized. Nyob rau hauv ib qho chaw hluav taws xob, dej zoo li polarize, yuav luag tshem tawm cov txiaj ntsig ntawm thaj teb.
Vim li cas lub dielectric qhov tsis tu ncua ntawm dej siab li 81?
Vim muaj cov parmanent dipole lub sij hawm cuam tshuam nrog dej molecule,,, yog li dej molecule muaj ntau dua dielectric dua mica.
Vim li cas dielectric tsis tu ncua siab?
Qhov dielectric tas li yog qhov piv ntawm permittivity ntawm ib yam khoom rau qhov permittivity ntawm qhov chaw dawb..
Vim li cas lub dielectric qhov tsis tu ncua ntawm dej siab li 81 thaum mica yog 6?
Dej muaj qhov chaw tsis sib xws li piv rau mica. Vim nws muaj lub sijhawm dipole mus tas li, nws muaj qhov dielectric ntau dua li piv rau mica.
Puas dej nce dielectric tas li?
Conversely, kua dej yog ib qho hnyav rau cov khoom siv polar vim nws cov dielectric siab tas li (Meyer li al., 1992; Wagner and Kretzschmar 2008). Nrog nce siab thiab kub, qhov dielectric tas li ntawm cov dej ua kua txo qis.

Leej twg qhia txog qhov tsis tu ncua dielectric?
Lub sij hawm dielectric yog coined los ntawm William Whewell (los ntawm dia + hluav taws xob) teb rau qhov kev thov los ntawm Michael Faraday. Lub dielectric zoo meej yog cov khoom siv nrog xoom hluav taws xob conductivity (cf. Leej twg nrhiav tau dielectric tas li?
Qhov twg yog qhov tsis txaus siab lossis tsis txaus siab?
Nyob rau hnub no kev siv, tsis txaus siab feem ntau feem ntau txhais tau tias "tsis muaj kev ncaj ncees," whereas uninterested tsuas txhais tau tias "tsis txaus siab." Interestingly, thaum cov lus no tau xub qhia lawv lub ntsiab lus yog qhov thim rov qab, nrog lub ntsiab lus tsis txaus siab ntawm lub ntsiab lus "
Puas yog tus lej tsis tu ncua / tsis tu ncua?
Integer constants yog cov ntaub ntawv tas mus li uas tsis muaj feem feem lossis exponents. … Koj tuaj yeem teev tus lej tsis tu ncua hauv daim decimal, octal, lossis hexadecimal daim ntawv. Lawv tuaj yeem qhia hom kos npe lossis tsis kos npe thiab hom ntev lossis luv.
Vim li cas qhov tseem ceeb ntawm qhov muaj zog thiab qhov tsis muaj zog yog qhov tseem ceeb?
Nws yog ib qho tseem ceeb rau qhov tseem ceeb ntawm qhov ua tau zoo thiab qhov tsis muaj zog vim qhov no pab lub tuam txhab txiav txim siab txog thaj chaw uas lawv yuav tsum tau txhim kho ntxiv rau thaj chaw uas lawv ua tau zoo hauv. Vim li cas lub zog thiab qhov tsis muaj zog tseem ceeb?
Thaum qhov kev ncua deb me me qhov twg ntawm qhov yuam kev hauv qab no tsis tsim nyog?
Thaum qhov kev ncua deb me me qhov twg ntawm qhov yuam kev hauv qab no tsis tsim nyog? Nqe lus piav qhia: Cov txiaj ntsig ntawm curvature yog txhawm rau nyeem cov pas nrig. Thaum qhov deb me me qhov yuam kev yog negligible. Qhov twg ntawm qhov yuam kev hauv qab no los ntawm tus kheej yuam kev?
