Nws puas zoo dua rau cov hlau nplaum tiv thaiv hlau qws kom muaj kev sib nqus siab dua

Qhov sib nqus permeability ntawm cov hlau nplaum tiv thaiv hlau pas nrig tsis tas yuav zoo dua qhov siab dua, thiab nws cov kev xaiv yuav tsum xav txog ntau yam ua tiav. Cov hauv qab no yog ib qho kev ntsuam xyuas ntxaws ntawm qhov teeb meem no:
1, Kev cuam tshuam ntawm magnetic permeability ntawm magnetic shielding nyhuv
Kev sib raug zoo: Feem ntau, cov khoom siv nrog cov hlau nplaum permeability siab dua muaj peev xwm ua tau zoo dua los coj cov kab hlau nplaum sib nqus, yog li ua kom muaj kev tiv thaiv zoo dua. Lub siab permeability magnetic shielding hlau pas nrig tuaj yeem coj ntau cov kab sib nqus mus rau nws sab hauv, yog li txo qhov cuam tshuam ntawm cov hlau nplaum sab nraud ntawm thaj chaw tiv thaiv.
Cov nyhuv saturation: Txawm li cas los xij, thaum qhov sib nqus permeability nce mus rau qee qhov, cov khoom yuav muaj kev sib nqus saturation. Sib nqus saturation yog hais txog qhov xwm txheej uas cov khoom siv magnetization nce mus txog qhov txwv tus nqi nyob rau hauv kev cuam tshuam ntawm sab nraud magnetic teb thiab tsis muaj kev nce ntxiv nrog qhov nce ntawm sab nraud magnetic teb lub zog. Nyob rau hauv lub xeev ntawm magnetic saturation, lub magnetic permeability ntawm cov khoom yuav sharply txo, ua rau ib tug qaug zog magnetic shielding nyhuv.
2, Lwm yam cuam tshuam
Tus nqi ntawm cov khoom siv: Cov khoom siv nrog cov hlau nplaum siab permeability feem ntau muaj cov nqi siab dua, yog li thaum xaiv cov hlau nplaum thaiv cov hlau nplaum, cov nqi tseem ceeb kuj yuav tsum tau xav txog. Ntawm qhov chaw ua tau raws li kev tiv thaiv kev tiv thaiv, cov khoom siv nrog cov nqi qis yuav tsum tau xaiv ntau li ntau tau.
Daim ntawv thov ib puag ncig: Cov ntawv thov sib txawv muaj qhov sib txawv rau kev sib nqus permeability ntawm magnetic shielding hlau tuav. Piv txwv li, nyob rau hauv cov xwm txheej uas yuav tsum tau muaj kev tiv thaiv zoo heev (xws li nyob ib ncig ntawm MRI cov cuab yeej), nws yuav tsum tau xaiv cov ntaub ntawv uas muaj zog sib nqus permeability; Hauv qee qhov xwm txheej uas tsis tas yuav muaj kev tiv thaiv kev ua tau zoo, cov khoom siv nrog cov sib nqus sib nqus permeability tuaj yeem xaiv.
Thickness factor: Ntxiv nrog rau kev sib nqus permeability, lub thickness ntawm cov hlau nplaum tiv thaiv hlau pas nrig kuj yog ib qho tseem ceeb cuam tshuam rau nws cov kev ua tau zoo. Feem ntau hais lus, qhov tuab tuab, qhov zoo dua cov nyhuv thaiv, tab sis nws kuj nce tus nqi thiab qhov hnyav.
Hauv cov ntsiab lus, qhov sib nqus permeability ntawm cov hlau nplaum thaiv cov hlau nplaum tsis tas yuav zoo dua nrog cov txiaj ntsig siab dua, tab sis yuav tsum tau xaiv cov ntaub ntawv tsim nyog raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau. Thaum xaiv, ntau yam xws li sib nqus permeability, nqi, thickness, thiab daim ntawv thov ib puag ncig yuav tsum tau muab xam kom pom qhov zoo tshaj qhov sib npaug. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau qhov tshwm sim sib nqus saturation ntawm cov khoom kom tsis txhob xaiv cov khoom sib nqus siab heev, uas yuav ua rau txo qis hauv kev tiv thaiv.
Nkag siab txog cov khoom siv: Ua ntej xaiv cov hlau nplaum tiv thaiv hlau nplaum, nws yog ib qho tsim nyog yuav tsum nkag siab tag nrho cov magnetic permeability, saturation magnetic induction intensity, thiab lwm yam ntxwv ntawm cov khoom sib txawv nyob rau hauv thiaj li yuav ua tau zoo raws li daim ntawv thov.
Kev sab laj cov kws tshaj lij: Rau cov xwm txheej tseem ceeb ntawm daim ntawv thov, nws raug nquahu kom sab laj cov kws tshaj lij hauv kev lag luam hlau nplaum lossis electromagnetic shielding rau cov lus qhia thiab kev taw qhia kom raug.
Kev sim tshuaj xyuas: Yog tias muaj kev tso cai, cov kev sim tuaj yeem ua tau los xyuas qhov kev tiv thaiv ntawm cov khoom sib txawv nyob rau hauv cov xwm txheej sib txawv, txhawm rau xaiv cov hlau nplaum hlau nplaum uas tsim nyog tshaj plaws.
