Kugawanika kwa dielectrics

chodabwitsa A amene amapezeka insulator ndi zochepa kuchuluka kwa milandu kusamutsidwa okhudzana, kapena pali kukhota dipoles magetsi, analandira udindo mu sayansi kugawanika kwa dielectrics. Pa ndondomeko izi zingachitike kaya zokha, chifukwa cha zinthu mkati, kapena mutamwa mphamvu zakunja woyamba wa zonse, minda magetsi.

The physico-masamu ndondomeko chinyezimiro wofanana ndi kugawanika vekitala akuimira dipole kamphindi, zomwe zimaoneka poyerekezera ndi kukula kwa buku dielectric. Nthawi zambiri kulingana thupi la ntchito ya m'Chingelezi chosavuta mawu - kugawanika. chizindikiro ichi ntchito osati kusonyeza boma macroscopic. Thiabendazole angagwiritsidwe ntchito kutifotokozera aliyense ndi katundu zomwe ndi kugawanika kwa dielectrics.

Pamaziko a mawu amenewa, titha zopanga chizindikiro wamba chodabwitsa lapansi. Chotero boma la dielectric mu umene wapezeka pamaso pa dipole mphindi pa mfundo iliyonse ya m'buku ake, ndipo amadziwika ndi kugawanika kwa dielectrics.

zodabwitsazi ndi osokoneza m'chilengedwe. Kusiyanitsa mitundu monga kugawanika anachititsa wa dielectrics, kuti chifukwa cha zochita za m'minda kunja magetsi, mowiriza, anapanga pakalibe wothandizila kunja kugawanika makina (ferroelectric) aumbike mwa zochita za wothandizila makina, kutentha zomwe ukapezeka chifukwa kusinthasintha kutentha.

Mbali yapadera ya kugawanika monga chodabwitsa thupi ndi kuti ali pafupifupi ziribe mphamvu pa mtengo wa mtengo okwana ndi dielectric kwenikweni chilichonse mfundo voliyumu yake sanasankhidwe. Pa nthawi yomweyo, kugawanika limapezeka pa mapangidwe milandu omangidwa padziko dielectric. milandu izi magwero a kuthengo ndi zina mavuto zina, amene anali osiyana ndi vekitala wa kumunda kunja vekitala.

Zofunika pa nkhaniyi akuyima, ndipo kugawanika kwa dielectrics gulu malinga zifukwa zake. Chikutanthauza amaphatikizapo mitundu amenewa:

- Ataliatali ndi khalidwe la zipangizo zimene kapangidwe ndi bwino zigawo zooneka ndi madutsidwe osiyana. kugawanika amenewa amakhala ndi kanthu mochedwa;

- pakompyuta kugawanika ndi kulimbikitsa zipolopolo maatomu mchikakamizo cha minda kunja magetsi. Izi - mtundu yachangu ya kugawanika;

- ion amakhala ndi zinthu zomwezo monga zamagetsi, koma mu nkhani iyi palibe kusamuka kwa zipolopolo za maatomu, zokwawa mfundo dongosolo galasi latisi zinthu;

- dipole, kapena monga patchedwa lathu kugawanika amakhala ndi zomvetsa ndithu, chifukwa cha zomwe ndi ndalama lalikulu la mphamvu yogonjetsera yogwirizana mkati mwa dielectric lapansi. Pakuti lathu la kugawanika kwa dielectric khalidwe chodabwitsa lathu bwino chikhalire wa dipoles;

- elekitironi zosangalatsa amakhala ndi enieni lathu chilema cha ma elekitironi;

- ion-zosangalatsa kugawanika dielectrics tikuonera kusuntha ayoni kuti likhale ofooka kugwirizana mkati ndi kuliika stably mu dongosolo galasi latisi mfundo chuma;

- chipika ndi amasonyezanso kuloza makamaka dielectric zinthu, koma mu nkhani iyi zinthu izi ndi zosafunika zosiyanasiyana, zomwe limapangidwa chinthu dielectric. kugawanika Izi zimachitika pang'onopang'ono;

- mowiriza (mowiriza) anati mu dielectrics ndi magawo kwambiri permeability, iwo amatchedwa ferroelectrics;

- yodziwika mwangozi dielectric kumveka pafupipafupi ma elekitironi pa mafurikwense akuchita adalira munda, choncho mosamalitsa kulankhula, dzina amenewa.

Monga ulamuliro, kwa milandu onse, kupatulapo kugawanika resonant, phindu lake kufika pazipita m'minda malo amodzi.
