Lub permittivity ntsuas qhov cuam tshuam tsim los ntawm cov khoom tsimntawm hluav taws xob teb, whereas lub permeability yog lub peev xwm ntawm cov khoom tso cai rau magnetic kab los ntawm nws. … Lub permittivity tsim lub teb hluav taws xob, whereas lub permeability tsim lub magnetic teb.
Dab tsi yog cov khoom ntawm permeability thiab permittivity?
Yog li, cov khoom ntawm permeability ntawm qhov chaw dawb thiab permittivity yog 1/c^2.
Dab tsi yog hu ua permittivity?
Nyob hauv electromagnetism, qhov kev tso cai tsis raug, feem ntau hu ua permittivity thiab denoted los ntawm Greek tsab ntawv ε (epsilon), yog ib qho kev ntsuas ntawm hluav taws xob polarizability ntawm ib dielectric. … Qhov no dimensionless ntau kuj yog feem ntau thiab ambiguously xa mus rau raws li permittivity.
kev tso cai ntawm cov khoom yog dab tsi?
: lub peev xwm ntawm cov khoom siv los khaws cov hluav taws xob muaj peev xwm nyob rau hauv kev cuam tshuam ntawm qhov hluav taws xob ntsuas los ntawm qhov sib piv ntawm lub peev xwm ntawm lub capacitor nrog cov khoom siv raws li dielectric rau nws cov capacitance nrognqus raws li dielectric.
Kev sib raug zoo ntawm kev tso cai ntawm qhov chaw dawb permeability thiab ceev ntawm lub teeb yog dab tsi?
Lub teeb nrawm yog cuam tshuam nrog hluav taws xob permittivity ntawm qhov chaw dawb εo thiab sib nqus permeability ntawm qhov chaw dawb μo.

Dab tsi yog permeability ntawm av?
Ntau yam cuam tshuam rau permeability ntawm cov av, los ntawm qhov loj me, impurities nyob rau hauv dej, void ratio, degree ntawm saturation, thiab adsorbed dej, rau entrapped huab cua thiab organic khoom. txhais li cas los ntawm permeability ntawm av?
Puas permeability thiab porosity tib yam?
Qhov tshwj xeeb tshaj yog, qhov porosity ntawm pob zeb yog qhov ntsuas ntawm nws lub peev xwm tuav cov kua dej. … Permeability yog ib qho kev ntsuas ntawm qhov yooj yim ntawm ntws ntawm cov kua los ntawm cov khoom ntxeem tau. Lub pob zeb yuav ntxeem tau heev, tab sis yog tias cov pores tsis txuas nrog, nws yuav tsis muaj permeability.
In permeability thiab porosity?
Qhov tshwj xeeb tshaj yog, qhov porosity ntawm pob zeb yog qhov ntsuas ntawm nws lub peev xwm tuav cov kua dej. Ua lej, nws yog qhov chaw qhib hauv pob zeb faib los ntawm tag nrho cov pob zeb ntim (khoom thiab qhov chaw). Permeability yog ib qho kev ntsuas ntawm qhov yooj yim ntawm cov dej ntws los ntawm cov khoom ntxeem tau.
Puas yog porosity thiab permeability cuam tshuam?
Qhov tshwj xeeb tshaj yog, qhov porosity ntawm pob zeb yog qhov ntsuas ntawm nws lub peev xwm tuav cov kua dej. … Permeability yog ib qho kev ntsuas ntawm qhov yooj yim ntawm cov kua ntws los ntawm cov khoom ntxeem tau. Lub pob zeb yuav ntxeem tau heev, tab sis yog tias cov pores tsis txuas nrog, nws yuav tsis muaj permeability.
Puas av nplaum puas muaj permeability siab?
Av nplaum yog cov porous tshaj plaws tab sis yog qhov permeable tsawg kawg. Av nplaum feem ntau ua raws li dej ntws, cuam tshuam cov dej ntws. Pob zeb thiab xuab zeb yog ob qho tib si ntxeem tau thiab permeable, ua rau lawv zoo aquifer cov ntaub ntawv.
