Tus tam sim no cov kev taw qhia: los ntawm Rho tawm mus ntxiv rau thiab vice versa?
Peb txhua tus yeej paub hais tias hluav taws xob yog ib tug qhia ndlwg ntawm them hais los ntawm tej yam uas cov hluav taws xob field. Qhov no yuav qhia rau koj tej me nyuam kawm ntawv. Tab sis cov nqe lus nug ntawm yog dab tsi yog tam sim no cov kev taw qhia thiab ua li cas rau cov tib hais, muaj ntau yam yuav paus.
Tus taw tes ntawm qhov teeb meem
Raws li yog lub npe hu, nyob rau hauv hluav taws xob neeg xyuas pib kis electrons nyob rau hauv electrolytes - cations thiab anions (los yog tsuas yog ions), electrons nyob rau hauv semiconductors ua hauj lwm nrog thiaj li hu ua "qhov", nyob rau hauv lub gases - ions thiab cov electrons. Los ntawm cov muaj ntawm lub elementary hais nyob rau hauv ib tug muab cov ntaub ntawv thiab nws cov hluav taws xob conductivity nyob. Nyob rau hauv lub qhaj ntawv ntawm ib tug hluav taws xob field nyob rau hauv lub hlau tam sim no neeg xyuas pib yuav tsis mus. Tab sis ib zaug nws ob sections tshwm sim ib tug neeg txawv, i.e., voltage zoo nkaus li nyob rau hauv lub electron tsab ntawv tsa suab thiab tsis txhob chaos los txiav txim uas lawv yuav tsum repelled los ntawm lub Rho tawm thiab ntxiv mus ntawm. Nws yuav zoo li, yog cov lus teb rau lo lus nug "yog dab tsi tam sim no cov kev taw qhia?". Tab sis nws muaj nws yog. Cia li saib cov encyclopedia los yog cia li nyob rau hauv tej physics phau ntawv nyeem, xws li tam sim ntawd yuav noticeably ib tug contradiction. Nws hais tias lub zwj ceeb kab lus "tam sim no cov kev taw qhia" qhia cov kev taw qhia ntawm lub zog ntawm zoo nqi, nyob rau hauv lwm yam lus, los ntawm ntxiv mus rho tawm. Yuav ua li cas nrog no daim ntawv qhia? Tom qab tag nrho, qhov no mus cov liab qab qhov muag npaum li cas controversy!
Force ntawm tus cwj pwm
Thaum cov neeg kawm tau mus ua lub Circuit Court ntawm DC, lawv tsis tau paub txog lub hav zoov ntawm cov electron. Tshwj xeeb tshaj yog, thaum lub sij hawm peb tsis xav hais tias nws yog tsiv los ntawm Rho tawm mus ntxiv. Thaum lub amp muaj nyob rau hauv thawj ib nrab ntawm lub xyoo pua puv 19, tam sim no cov kev taw qhia no yog los ntawm ntxiv mus rho tawm, tag nrho cov coj nws khuv xim thiab qhov kev txiav txim tsis muaj ib tug disputed. Nws coj tau 70 xyoo, mus txog rau thaum cov neeg pom tias tam sim no nyob rau hauv cov hlau yog vim lub zog ntawm electrons. Thiab thaum lawv twb paub lawm (nws tshwm sim nyob rau hauv 1916), tag nrho ces siv rau cov kev xaiv ua los ntawm Ampere uas twb tsis hloov dab tsi.
"Tus Golden txhais li cas"
Lub electrolytes zoo them hais tsiv mus nyob rau lub cathode thiab zoo - mus rau lub anode. Cov tib yam tshwm sim nyob rau hauv roj cua. Yog hais tias koj xav txog dab tsi coj tam sim no yog nyob rau hauv cov ntaub ntawv no, los txog rau lub siab tsuas yog ib qho kev xaiv: Txav mus rau tus bipolar hluav taws xob nqi nyob rau hauv ib tug kaw Circuit Court mus rau txhua lwm yam. Yog hais tias peb coj daim ntawv no raws li ib lub hauv paus, nws yuav tshem tawm cov uas twb muaj lawm tam sim no muaj teeb meem. Tej zaum nws yuav ua rau surprise, tab sis tseem ntau tshaj 70 xyoo dhau los, zaum tau muab teev rau hauv lub fact tias qhov fab ntxeev kos npe rau hluav taws xob nqi nyob rau hauv ib tug conductive nruab nrab yog tiag tiag tsiv mus rau txhua lwm yam. Qhov no daim ntawv qhia no yeej muaj tseeb rau tej neeg xyuas pib yog nyob ntawm seb lub hom hlau, roj, ntsha semiconductor. Txawm nws yog, nws yog vam hais tias yuav rhuav tshem tsis meej pem nyob rau hauv lub terminology ntawm niaj hnub physics thiab txais yuav ib tug unambiguous txhais ntawm yog dab tsi nws hais tias xws li ib tug kev taw qhia ntawm cov tam sim no lub zog. Cwj pwm, ntawm chav kawm, kev hloov no yog tsis yooj yim, tab sis koj yuav tsum thaum kawg muab tso rau txhua yam nyob rau hauv nws qhov chaw.
