Thaum negative porosity yog kom meej meej tsis yooj yim sua, qhov ntsuas tau teem rau qhov pom meej porosity. Txhua cheeb tsam uas muaj qhov ntom ntom ntau dua li limestone nrog xoom porosity (piv txwv li calcite, ntom 2.71 gm / cc) yuav tshwm sim kom muaj "tsis zoo porosity. "
Puas yog qhov piv txwv tsis zoo?
Void ratio yog qhov piv ntawm qhov ntim ntawm cov voids rau tag nrho ntim thiab yog li tsis tuaj yeem tsis zoo yogpeb ua raws li txoj cai.
qhov porosity ntawm 1 txhais li cas?
Porosity yog feem pua ntawm qhov chaw khoob hauv pob zeb. Nws txhais tau tias yogpiv ntawm qhov ntim ntawm qhov khoob lossis qhov chaw pore faib los ntawm tag nrho ntim Nws tau sau ua ib feem kaum ntawm 0 thiab 1 lossis feem pua. Rau feem ntau pob zeb, porosity txawv ntawm tsawg dua 1% mus rau 40%.
Dab tsi yog chav tsev ntawm porosity?
Porosity tseem hu ua "pore space." Qhov hnyav ntawm ib tus neeg av particle ib chav tsev ntim. Particle ntom feem ntau yog qhia nyob rau hauv units ntawm grams ib cubic centimeter (g/cm2).
peb hom porosity yog dab tsi?
Porosity plays lub luag haujlwm tseem ceeb hauv geology. Muaj peb hom: qis, nruab nrab thiab siab.
