Lub permeability ntawm cov hlau ntshiab yog hais txog nws lub peev xwm tso cai rau kev nkag los yog nkag mus rau qee yam khoom, xws li roj av, kua, lossis cov chaw sib nqus.
Gas thiab kua permeability:
Cov hlau ntshiab, ua cov ntaub ntawv tuab me me, feem ntau muaj cov pa roj hmab tsawg dua rau roj av thiab kua dej nyob rau hauv ib txwm muaj. Qhov no txhais tau hais tias cov pa roj thiab cov kua dej tsis yooj yim diffuse los ntawm cov qauv ntawm cov hlau ntshiab.
Sib nqus Permeability:
Ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawm cov hlau ntshiab yog nws cov magnetic permeability siab. Qhov no yog hais txog qhov yooj yim uas cov kab hlau nplaum tuaj yeem dhau los ntawm cov khoom siv. Cov hlau ntshiab yog cais raws li cov khoom siv ferromagnetic, uas txhais tau tias nws tuaj yeem ua kom muaj zog hlau nplaum thaum muab tso rau hauv qhov chaw sib nqus sab nraud. Nws lub siab sib nqus permeability ua rau nws zoo tagnrho rau kev siv hauv electromagnets, transformers, thiab lwm yam khoom siv hluav taws xob thiab hluav taws xob.
Lub cev thiab cov qauv tsim:
Lub permeability ntawm cov hlau ntshiab kuj tuaj yeem cuam tshuam los ntawm nws cov microstructure, xws li grain loj, porosity, thiab muaj impurities los yog alloys. Piv txwv li, cov ntsiab lus alloying tuaj yeem hloov cov khoom sib nqus ntawm cov hlau, cuam tshuam rau nws cov permeability.
Daim ntawv thov:
Lub siab sib nqus permeability ntawm cov hlau ntshiab yog qhov tseem ceeb rau ntau yam kev lag luam thiab kev siv thev naus laus zis. Nws yog dav siv nyob rau hauv hluav taws xob transformers, generators, thiab motors vim nws muaj peev xwm mus cuag tau zoo thiab hloov magnetic zog.
Hauv cov ntsiab lus, qhov permeability ntawm cov hlau ntshiab, nyob ntawm cov ntsiab lus, tuaj yeem xa mus rau nws lub peev xwm los tso cai rau kev nkag mus ntawm cov pa roj, kua, lossis cov hlau nplaum. Nws lub siab sib nqus permeability yog qhov tseem ceeb thiab yog qhov tseem ceeb hauv nws txoj kev siv hluav taws xob thiab hluav taws xob.
