Qhov Tseem Ceeb Qhov Sib Txawv - Kev Coj vs Induction
Qhov sib txawv tseem ceeb ntawm kev coj ua thiab induction yog tias, nyob rau hauv conduction, lub zog yog pauv los ntawm kev ua hauj lwm teeb meem thaum, induction, tsis muaj nruab nrab los yog kev sib cuag yuav tsum tau hloov mus rau lub zog.
Kev coj ua yog dab tsi?
Kev coj ua yog txheej txheem uas hloov lub zog los ntawm thermal lossis hluav taws xob daim ntawv. Nyob rau hauv thermal conduction, atoms nyob rau hauv nruab nrab vibrate thiab hloov tshav kub, nyob rau hauv lwm yam lus, thermal zog. Nyob rau hauv thermal conduction, atoms nyob rau hauv nruab nrab nquag hloov lub zog los ntawm kev vibrations. Thermal zog yog ya los ntawm atom mus rau atom tsuav yog muaj qhov kub thiab txias gradient. Feem ntau ntawm cov thermal conductors zoo yog cov khoom khib nyiab. Lawv cov qauv zoo sib xws pab cov khoom siv los ua cov khoom siv tau zoo. Tab sis nws yuav tsum tau muab sau tseg tias tag nrho cov khib nyiab tsis zoo cua sov conductors. Kev coj ua yog ib txoj hauv kev hloov cov cua sov; Thaum tshav kub kub tuaj yeem kis tau los ntawm convection thiab hluav taws xob zoo li. Nco ntsoov; Peb tsuas yog cua sov rau sab nraud, tsis yog sab hauv ntawm lub lauj kaub ua noj. Txhua yam qab ntawm lub lauj kaub tuaj yeem ua kom siav vim tias qhov kub ntawm qhov hluav taws kub mus rau cov zaub mov los ntawm kev coj ua.
Cov neeg nqa khoom them nqi ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob. Muaj peev xwm sib txawv uas yog txuas los ntawm tus neeg xyuas pib kuj yuav tsum tau ua kom siv tau. Cov hlau feem ntau yog cov khoom siv hluav taws xob zoo vim tias lawv muaj cov hluav taws xob delocalized uas tuaj yeem ntws thiab nqa tam sim no. Cov kev daws teeb meem xws li acids muaj ions uas pub dawb los ua haujlwm raws li tus neeg nqa khoom them nqi. Yog li ntawd, acidic daws ua raws li hluav taws xob conductors. Cov dej ntshiab tsis ua hluav taws xob, tab sis cov dej tshiab tuaj yeem ua hluav taws xob vim cov dej tshiab muaj cov ions me me.
Induction yog dab tsi?
Lub sij hawm induction yog hu ua orientation hauv kev siv. Raws li phau ntawv txhais lus, kev taw qhia yog txhais tau tias yog kev hloov kho lossis kev sib haum xeeb ntawm tus kheej lossis ib tus tswv yim rau ib puag ncig lossis xwm txheej. Obviously, ob tog yuav tsum koom rau hauv txoj kev taw qhia. Ib yam li ntawd, nyob rau hauv tus txheej txheem induction, ib tug yuav tsum tau kho nws zoo raws li lwm yam.
Hauv Physics, induction yog faib ua electrostatic induction thiab electromagnetic induction. Electrostatic induction yog kev hloov pauv ntawm cov nqi hluav taws xob electrostatic ntawm ib qho khoom thaum muaj cov nqi sab nraud. Xav txog qhov nruab nrab ntawm cov hlau kheej kheej. Yog hais tias tus pas ntsuas raug coj los ze rau ntawm tus kheej, nruab nrab atoms yuav ionize thiab faib ua ob ntu. Tom qab ntawd cov nqi zoo li yuav tawm tsam ib leeg thiab ua rau cov nqi hauv qab no. Tsis xav tau kev sib cuag ntawm tus pas nrig thiab tus kheej kheej rau txoj haujlwm no. Qhov kev sib cais no tsuas yog tshwm sim los ntawm electrostatic induction. Cov qhab nia mus rau Michael Faraday rau kev tshawb pom lub electromagnetic induction. Electromagnetic induction tshwm sim vim lub sij hawm sib txawv magnetic teb. Lub zog electromotive tuaj yeem tsim tawm thoob plaws ib tus neeg xyuas pib los ntawm kev sib txawv ntawm qhov chaw sib nqus nyob ib puag ncig nws. Tsis xav tau kev sib cuag rau cov txheej txheem no. Lub zog electromotive tsuas yog tsim los ntawm electromagnetic induction.
Electrostatic precipitators nquag siv lub tswv yim ntawm electrostatic induction kom tshem tawm cov khoom los ntawm kev lag luam soot. Lub transformer yog siv los ua ib qho tseem ceeb, los ntawm cov chaw nres tsheb fais fab mus rau cov khoom siv hauv tsev, Nws yog siv los ua kom muaj qhov hluav taws xob thiab txo qhov voltage. Cov chaw nres tsheb fais fab feem ntau muaj cov kauj ruam-up transformers kom nce qhov voltage thiab pub rau cov kab sib kis, ces tej zaum yuav muaj ob peb lub ntsiab lus nyob rau hauv cov kab xa mus rau theem-down voltage mus rau ib qho kev nyab xeeb rau cov khoom siv hauv tsev. Qhov tseem ceeb tshaj plaws ntawm transformer yog tias nws tsis muaj kev sib txuas ncaj qha ntawm cov tswv yim (thawj) thiab cov zis (secondary), tab sis hloov lub zog ntawm thawj mus rau theem nrab. Qhov kev thov tshiab ntawm electromagnetic induction yog lub induction cooker. Nws yog cov khoom siv hauv chav ua noj uas tsis muaj dej soot.
Dab tsi yog qhov sib txawv ntawm Kev Coj thiab Induction?
Kev txhais ntawm kev coj ua thiab induction
Kev coj ua: Kev coj ua yog txheej txheem uas lub zog hluav taws xob xa mus los ntawm kev sib tsoo ntawm cov molecules nyob sib ze.
Induction: Induction yog txheej txheem uas hluav taws xob xa hluav taws xob ntawm ib yam khoom mus rau lwm qhov yam tsis muaj cov khoom kov.
yam ntxwv ntawm kev coj ua thiab induction
Kev hloov pauv zog
Kev coj ua: Kev coj ua yog ib txoj hauv kev hloov lub zog los ntawm kev ua haujlwm.
Induction: Induction yuav tsum tsis muaj nruab nrab lossis tiv tauj kom hloov lub zog.
txheej txheem
Kev coj ua: Kev coj ua nres thaum lub sijhawm kev coj ua tawg.
Induction: Induction nres thaum twg ob tog rov qab ib leeg mus ib txhis.
Gradient Path
Kev coj ua: Kev coj ua yog qhov kawg rau qhov kawg. Txhawm rau kom muaj qhov tshwm sim, qhov sib txawv lossis qhov sib txawv ntawm qhov kub thiab txias yuav tsum raug tsim.
Induction: Induction tsis xav tau txoj kev gradient.
