Nrhiav qhov sib piv ntawm bulk ntom rau particle ntom thiab multiplying los ntawm 100 xam cov feem pua ntawm cov khoom qhov chaw , yog li rho tawm tus nqi ntawm 100 muab % ntawm cov av ntim uas yog qhov pore.

Xav txog qhov no, koj ua li cas suav pore ntim?

Ib pore ntim = ntim luas = 0.737 m3 x 0.40 m3/m3 = 0.295 m3. Luas = 0.295 m3 x (1 x 106 cm3)/(1 m3) = 295,000 cm3 = 295 liters. Tom qab 7 hnub ntawm kev tso dej, 70 litres tau sau. Yog li, (70 L) / (295 L) = 0.24 lossis txog 1/4 pore ntim.

Ib sab saum toj no, ntau npaum li cas ntawm cov av feem ntau nyob ntawm qhov chaw pore? Tag nrho ntim ntawm nto av yog li ntawm 50% solids, feem ntau av particle (45%), thiab organic teeb meem ( feem ntau <5%); thiab txog 50% qhov pore uas tau ntim nrog huab cua lossis dej (Daim duab 1).

Kuj Paub, qhov pore tag nrho yog dab tsi?

los yog. Porosity yog qhov ntsuas ntawm qhov tag nrho qhov pore hauv av. Qhov no yog ntsuas raws li qhov ntim lossis feem pua. Tus nqi ntawm porosity nyob rau hauv ib tug av nyob ntawm seb cov minerals uas ua rau cov av thiab tus nqi ntawm sorting uas tshwm sim nyob rau hauv cov av qauv.

Dab tsi yog qhov kev sib raug zoo ntawm particle loj thiab feem pua ntawm qhov pore qhov chaw?

Tsawg dua loj cov khoom tuaj yeem tuav tib lub ntim ntawm cov av kom muaj tsawg dua pores thiab tsawg porosity. Compaction txo porosity li bulk ntom. Yog hais tias compaction nce bulk ntom ntawm 1.3 mus rau 1.5 g / cm23, porosity txo los ntawm 50 feem pua rau 43 feem pua.
