Domains yog thaj tsam ntawm homogeneous magnetization sib cais los ntawm cov phab ntsa, qhov chaw uas qhov kev taw qhia ntawm lub sijhawm atomic hloov pauv sai heev (Tshooj II. C). Lub vector magnetizations ntawm lub domains sum rau xoom hauv lub xeev demagnetized.
Thaum cov khoom siv ferromagnetic nyob rau hauv lub xeev unmagnetized lub domains yog?
Domains yog me me thiab randomly oriented nyob rau hauv ib yam khoom uas tsis muaj hlau nplaum ferromagnetic. Nyob rau hauv teb rau sab nraud magnetic teb, cov thawj yuav loj hlob mus rau millimeter loj, aligning lawv tus kheej raws li qhia nyob rau hauv daim duab 2(b).
Cov ntaub ntawv ferromagnetic puas tuaj yeem demagnetized?
Cov ntaub ntawv ferromagnetic tuaj yeem demagnetized los ntawm peb txoj kev hauv qab no: Kub tshaj Curie kub (Curie kub yog alloy nyob ntawm kev lag luam steels yog li 500 ° C txog 800 ° C thiab pib hloov dua siab tshiab los ntawm Ferromagnetism rau Paramagnetism).
Dab tsi tshwm sim rau lub npe hauv cov khoom siv ferromagnetic?
Yog li kev siv cov hlau nplaum sib nqus rau cov khoom siv ferromagnetic feem ntau ua rau cov phab ntsa domain txav kom nce qhov loj ntawm cov lus dag feem ntau sib npaug rau thaj chaw, ntawm tus nqi txo qhov loj ntawm cov thawj. tawm tsam thaj teb Qhov no yog qhov tshwm sim thaum cov ntaub ntawv ferromagnetic yog "magnetized ".
Yuav ua li cas rau cov thawj hauv cov khoom siv ferromagnetic thaum cov khoom tso rau hauv ib qho chaw sib nqus sab nraud?
Thaum ib daim ntawm cov khoom ferromagnetic muab tso rau hauv ib qho chaw sib nqus sab nraud, ob yam tshwm sim. Cov kev sib tw hauv txhua qhov kev hloov pauv kom lub sijhawm sib nqus ntawm cov hluav taws xob ua kom zoo dua nrog cov kev taw qhia ntawm thaj chaw.

Cov khoom lag luam thiab cov khoom siv tau siv rau dab tsi?
Tshuaj thiab pillory Cov no tau siv rau txim rau tib neeg rau kev ua txhaum cai xws li kev cog lus lossis kev qaug dej qaug cawvCov neeg ua phem yuav zaum lossis sawv ntawm ib lub thav ntoo thiab cov neeg hauv zos yuav pov cov khoom noj lossis txawm tias pob zeb rau lawv.
Vim li cas cov kev siv nyiaj txiag thiab cov khoom siv tsis pom nyob hauv lub voj voog thib plaub?
Vim li cas cov kev siv nyiaj txiag thiab cov neeg ua lag luam tsis muaj ntsej muag nyob hauv plaub lub voj voog? Lawv ntsej muag tsis phim lawv lub siab uas tsis tuaj yeem paub qhov txawv ntawm yam khoom muaj nqis lossis tsis . Vim li cas kev rau txim ntawm cov neeg khib nyiab thiab cov neeg ua liaj ua teb haum?
Cov khoom siv thiab cov khoom siv dab tsi suav nrog hauv tsev muag?
Fittings tuaj yeem suav nrog cov khoom xws li cov rooj tog zaum dawb thiab cov khoom siv, cov khoom siv hauv chav ua noj, cov duab thiab cov iav daiFixtures, txawm li cas los xij, yuav suav nrog cov khoom siv sib xyaw, chav ua noj thiab chav ua haujlwm, ntaub pua plag, qhov rooj thiab chav dej suites, nrog rau lub boiler thiab cua sov system .
Cov khoom qab zib liab nyob rau hauv cov khoom qab zib nyob qhov twg?
Cov Candies liab tsuas yog muaj nyob rau qib nrog 5 lossis 6 xim. Yog li ntawd lawv tsis tshwm sim rau txhua qib. Qhov ntau xim cov qib muaj, qhov nyuaj nws feem ntau yog. Nyob zoo @BBehr . Qib nyuaj tshaj hauv Candy Crush yog dab tsi?
Vim li cas cov neeg siv khoom thiab cov khoom siv tau siv hauv c ++?
Lub hom phiaj ntawm kev siv getters thiab setters yog txhawm rau zais cov ntaub ntawv khaws cia thiab rov qab li casTxoj kev no, yog tias koj hloov tus cwj pwm, koj tsis tas yuav hloov tus lej. nyob rau hauv ib txhiab qhov chaw. Tab sis, yog tias koj tsis tas yuav hloov qhov kev siv, koj tau ua koj cov cai ntau dua thiab tau txais me ntsis los ntawm kev ua li ntawd .
