Txhua tus paub los ntawm kev paub txog qhov hluav taws xob hluav taws xob yog dab tsi, tab sis tsis yog txhua tus nkag siab lub cev ntawm qhov tshwm sim no, tshwj xeeb tshaj yog tias physics tsis nyiam qhov no thaum lub sijhawm kawm ntawv. Thiab rau ntau cov menyuam kawm ntawv, cov phau ntawv physics zoo li slurred. Cia peb sim kho cov teeb meem no los ntawm kev piav qhia qhov tshwm sim yooj yim.
ua liaj ua teb tom haujlwm
Lo lus "tam sim no" qhia tias peb tab tom tham txog kev txav mus los, tsis yog hais txog qhov tshwm sim zoo li qub. Qhov hluav taws xob tam sim no yog dab tsi? Qhov no tsuas yog qhov taw qhia txav ntawm cov khoom siv hluav taws xob hauv ib tus neeg xyuas pib lossis electrolyte. Classical conductors yog cov khoom ua los ntawm cov hlau. Lawv ib txwm suav hais tias txaus ntshai, nco ntsoov qhov no yog tias koj xav tau thawb tus neeg raug tsim txom tawm ntawm qhov chaw tam sim no. Qhov xwm ntawm cov hluav taws xob tam sim no hauv cov hlau yog txuam nrog cov khoom tshwj xeeb ntawm cov khoom. Qhov tseeb yog tias cov electrons hauv cov hlau yog dawb heev thiab sawv cev rau ib yam dab tsi zoo li kev lag luam sib sau. Yog li ntawd, cov khoom ntawm pawg no ua tam sim no yooj yim heev, nws yog ib qho yooj yim kom ua tiav cov lus taw qhia ntawm cov khoom.
Txheej xwm hauv kev daws teeb meem
Hluav taws xob tam sim no kuj zooyog kis los ntawm kev daws teeb meem ntawm cov khoom them nqi - ions. Nyob rau tib lub sij hawm, qhov zoo them cation hais txog mus rau cathode, qhov tsis zoo electrode, thiab anion hais, uas nws tus nqi yog tsis zoo, mus rau lub anode. Yog li, kev daws teeb meem nrog qhov tsis zoo thiab zoo ions, uas yog, nrog electrolytes, yog tus neeg xyuas pib zoo.
Vim li cas hloov tau?
Hom hluav taws xob tam sim no - qhov no yog li cas cov lus nug feem ntau tsim los ntawm kev xeem. Thiab nyob rau hauv cov lus teb, raws li txoj cai, lawv xav hnov: "tsis tu ncua lossis hloov pauv." Qhov txawv yog dab tsi? Direct tam sim no txav mus rau tib txoj kev, alternating tam sim no hloov nws cov kev taw qhia. Vim li cas thiaj xav tau kev hloov pauv tam sim no (xws li, nws puas tau muab rau hauv cov neeg siv khoom thiab hauv kev tsim khoom?). Qhov tseeb yog tias thaum siv alternating tam sim no, muaj ntau tsawg poob thaum nws kis tau tus kab mob. Yog li, kev xa hluav taws xob tau txais txiaj ntsig ntau dua.
Hluav taws xob thiab hlau nplaum
Dab tsi yog qhov hluav taws xob tam sim no? Nws tau pom los ntawm txhua tus neeg uas pom xob laim - tam sim no ntawm kev nruj thiab lub zog loj heev. Ib tug neeg siv ntau yam khoom ntawm tam sim no, piv txwv li, muaj peev xwm ua rau muaj qhov tshwm sim sib nqus: hauv inductors, motors thiab generators. Nws yog rau kev ua haujlwm ntawm cov kws tshawb fawb tshawb fawb uas peb tshuav qhov kev nplij siab ntawm lub neej niaj hnub no.

Dab tsi yog qhov hluav taws xob rau cov neeg nyob hauv Nordic lub teb chaws? Qhov no yog qhov ua rau ntawm lub teeb sab qaum teb, ib qho zoo kawg nkaus ntuj tshwm sim. Lwm qhov piv txwv ntawm cov hluav taws xob tam sim no tuaj yeem suav hais tias yog lub hnub ci cua, uas, nruj me ntsis hais lus,yog qhov ua rau lub teeb sab qaum teb. Qhov no yog ib tug kwj ntawm hais los ntawm corona ntawm lub hnub. Nws kuj tsim cov cua daj cua dub. Qhov kev khiav dej num no yog ib txwm muaj rau lub Hnub, tab sis qee tus neeg pheej ntsib cov xwm txheej ntawm lawv tus kheej.
Cov hluav taws xob tam sim no tuaj yeem ua rau muaj qhov tshwm sim thermal. Qhov yooj yim cua sov ntawm cov khoom siv ua haujlwm yog pov thawj ntawm qhov no. Thiab peb tab tom tham tsis yog hais txog cov cuab yeej tsim los rau cua sov, xws li boiler thiab lub rhaub. Kev mob tshwm sim - cua sov los ntawm hluav taws xob tam sim no - muaj ntau heev.
Hluav taws xob tam sim no tau ua haujlwm ncaj ncees rau txiv neej rau ntau xyoo lawm. Tab sis koj yuav tsum tau ceev faj heev nrog nws. Peb them nyiaj ntau pua lub neej rau hluav taws xob, txhua xyoo ntau tus neeg tuag vim kev tsis saib xyuas. Tam sim no tsis zam txim qhov yuam kev!
