Yam Koj Yuav Tsum Paub Txog Gauss

Ntau lub tuam txhab uas siv cov hlau nplaum hauv kev tsim siv lo lus "Gauss" txhua hnub. Qee cov neeg yuav tsis paub tias lub sij hawm pib los ntawm ib tug German mathematician hu ua Karl Friedrich Gauss, uas siv cov tswv yim lej los ntsuas cov txuj ci magnetism. Yog tias koj tsis muaj cov kev qhia tshwj xeeb, tej zaum koj yuav ua tau. Tseem ceeb dua, peb yuav tsum paub txog dab tsi Gauss txhais tau tias thiab nws tsis txhais tau li cas. Kuj ceeb tias, txawm nyob rau hauv cov tuam txhab uas cia siab rau cov khoom sib nqus, feem ntau tsis to taub.
Yeej tseem ceeb, Gauss hais txog qhov siv ntawm qhov sib nqus field, ua lwm yam lus, qhov sib txawv ntawm qhov sib txawv ntawm thaj chaw hauv ib cheeb tsam. Ib chav Gaussian yog ib txoj hlua khoob hauv ib thaj tsam ntawm 1 square centimeter. Lwm txoj hauv kev yog xav txog qhov ceev nti. Yog li ntawd, yog tias koj tuaj yeem xav pom cov khoom noj khoom haus thiab cov kab kos ntawm Arctic mus rau Antarctic, nws yog Gauss. Nws tsis yog hais txog qhov kev ncua deb uas tuaj txog ntawm qhov chaw magnetic tuaj, tab sis qhov kev ncua deb yuav muaj xwm yeem rau qhov sib nqus ntawm qhov sib nqus thiab cov qauv ntawm cov hlau nplaum. Hauv cov ntsiab lus tshaj lij, Gauss tseem yog kev ntsuas ntawm lub zog ntawm daim teb; nws yog qhov sib txawv ntawm txoj hauj lwm thiab ib qho vector (qhia), uas txhais tau hais tias txawv txoj haujlwm hauv qhov chaw muaj Gauss nyeem ntawv thiab lwm yam kev qhia. Feem ntau hais lus, Gauss yog txawv ntawm lub zog ntawm cov hlau nplaum. Kev siab Gausses tsis yog ua rau ua rau muaj zog zog dua. Gauss nyeem ntawv yog siv rau hauv cov kev siv uas lub zog ntawm lub cheeb tsam yog lub ntsiab parameter, xws li kev siv cov ntaub ntawv. Feem ntau, Gauss qib tsis tuaj yeem siv los sib piv ntawm cov hlau nplaum magnetic ntawm cov hlau nplaum tshwj tsis yog cov hlau nplaum muaj tib lub qauv ntawm cov qauv geometric thiab cov Gauss nyeem tau ntsuas ntawm qhov chaw qub. Hauv kev ntsuas, Gauss, G los sis GS rau luv luv, yog CGS unit ntawm magnetic field B, uas kuj hu ua "magnetic flux density" lossis "magnetic induction". Gauss txhais tias yog Maxwell ib thaj tsam centimeter. CGS system tau raug nthuav los ntawm SI system, uas siv Tesla (t) ua lub tsev ntawm B. A Tesla = 10,000 Gauss! Zoo, rov qab mus rau Lub Ntiaj Teb. Vim hais tias lub ntiaj teb magnetic teb yog li 0.5 Gauss, thiab cov tub yees koj tau yuav los tom khw pizza yog 10 Gauss, tej zaum koj yuav tsis yog lawm tias qhov hlau nplaum nyob rau hauv Al Pisa yog muaj zog dua hauv lub Ntiaj Teb. Tias 's ib lub tswv yim phem heev. Lub sib nqus teb yuav ncav cuag qhov twg hauv qhov chaw, tab sis nws txoj kev siv kuj tsawg zuj zus raws li qhov kev nce siab. Yog vim li cas airfreight teev ib qho Gaussian tus nqi ntawm ib qho deb ntawm 15 taw. Feem ntau, Gaussian qib qis me me ntawm qhov kev nrug no thiab tsuas yog ntsuas tau los ntawm ib qho ntsuas ntawm Gaussian thiab. Qhov muab xam yuav pab tau kwv yees lub zog ntawm qhov chaw nyob deb, tab sis kev tiv thaiv / ntim yuav tsis muab xam. Kev tuav xam yog ib txoj kev ntev thiab nyuaj. Qhov zoo ces, Adams tau muab ib qhov shortcut: ib lub tshuab xam phaj muas dawb rau Gaussian qib thiab nruj ntsuas. Peb cov lus teb yog xam raws qhov loj me thiab cov khoom siv ntawm ib cov hlau nplaum xwb.
