Thawj qhov sib npaug siv tag nrho ntim thiab cov ntim ntawm qhov khoob. Porosity = ( Ntim ntawm Voids / Total Ntim ) x 100%. Qhov sib npaug thib ob siv tag nrho ntim thiab cov ntim ntawm cov khoom. Porosity = ((Tag nrho Ntim - Ntim ntawm cov khoom) / Total Ntim ) x 100%.
Ib yam li ntawd, tib neeg nug, koj pom qhov porosity ntawm xuab zeb li cas?
Nov yog yuav ua li cas xam qhov fractional air space:
- Faib qhov chaw huab cua ntim (hauv mL) los ntawm qhov pib ntim ntawm xuab zeb (kuj hauv mL).
- Muab cov seem uas tau tshwm sim los ntawm 100.
- Qhov tshwm sim yog qhov feem pua ntawm cov thawj ntim ntawm cov xuab zeb uas nyob hauv huab cua nyob nruab nrab ntawm cov nplej.
Ib sab saum toj, dab tsi yog lub cim rau porosity? Los ntawm txhais, porosity yog qhov feem pua ntawm qhov ntim tsis muaj qhov muab faib los ntawm tag nrho cov ntim. Cov cim rau porosity yog Greek cim f. PRIMARY POROSITY : Thawj porosity tshwm sim los ntawm qhov chaw tsis muaj chaw nyob nruab nrab ntawm cov pob zeb hauv nruab nrab ntawm cov pob zeb tawg thiab cov hmoov nplej tom qab lawv cov pob zeb ua sediments.
Kuj nug, dab tsi yog txhais los ntawm porosity?
Porosity yog qhov zoo ntawm kev ua ntxeem tau , lossis tag nrho ntawm qhov me me. Cov kua dej mus ncaj qha los ntawm cov khoom uas muaj porosity . Rov qab mus deb txaus thiab koj yuav pom qhov ntawd porosity stems los ntawm Greek lo lus poros rau "pore," uas txhais tau tias “kev.” Yog li qee yam nrog porosity cia tej yam dhau mus.
Cov av porous tshaj plaws yog dab tsi?
Av nplaum av muaj qhov porosity siab tshaj plaws, thiab xuab zeb qis tshaj. Rau ib tug muab ntim ntawm av, xuab zeb hnyav dua thiab av nplaum tsawg dua, txawm tias qhov ntom ntom ntawm qhov sib npaug. Qhov txawv yog qhov loj ntawm qhov pores. Vim xuab zeb particle loj loj, yog li cov pores.

Dab tsi yog lub npe muab rau ib feem ntawm cov enzyme uas cov substrate khi rau?
Hauv biology, thaj chaw muaj txiaj ntsig yog thaj av ntawm cov enzyme uas cov txheej txheem txheej txheej sib txuas thiab ua rau cov tshuaj tiv thaiv kab mob. Qhov chaw ua haujlwm muaj cov seem uas tsim cov ntawv cog lus ib ntus nrog cov substrate (qhov chaw khi) thiab cov khoom seem uas ua rau cov tshuaj tiv thaiv ntawm cov substrate (catalytic site)
Puas yog cov txheej txheem uas hloov cov tswv yim rau hauv cov txiaj ntsig uas tuaj yeem raug muag raws li cov khoom lag luam thiab cov kev pabcuam?
Kev tswj hwm kev ua haujlwm hloov pauv cov tswv yim (kev ua haujlwm, peev txheej, khoom siv, av, vaj tse, khoom siv, thiab cov ntaub ntawv) rau hauv cov khoom (khoom thiab kev pabcuam) uas muab tus nqi ntxiv rau cov neeg siv khoom. Txhua lub koom haum yuav tsum siv zog ua kom zoo tshaj plaws ntawm lawv cov txheej txheem hloov pauv kom tau raws li cov neeg siv khoom xav tau
Dab tsi yog rau lub tshuab yooj yim thiab cov piv txwv ntawm lawv yog dab tsi?
Cov no yog rau lub tshuab yooj yim: cov nplais, lub log thiab lub qag, qib, lub dav hlau inclined, ntsia hlau, thiab lub log
Dab tsi ntawm cov hauv qab no yog hom kev lag luam uas tsom rau kev muab cov ntaub ntawv rau cov neeg siv sab hauv?
Kev lag luam nyiaj txiag tsom rau kev muab cov ntaub ntawv rau cov neeg siv sab hauv. cuav. (Lub hom phiaj tseem ceeb ntawm kev lag luam nyiaj txiag yog qhov tseeb kom tau txais cov ntaub ntawv rau cov neeg siv sab nraud xws li cov koom haum se, cov tswv lag luam, cov tub ua lag luam lossis cov neeg qiv nyiaj
Dab tsi yog cov cuab yeej lossis cov txheej txheem siv los hloov cov ntaub ntawv kev ua haujlwm rau hauv cov ntaub ntawv kev ua haujlwm hauv cov txheej txheem tswj Scope?
Variance Analysis yog ib qho cuab yeej & Cov txheej txheem ntawm Kev Tswj Scope Txheej Txheem thiab Kev Ntsuas Kev Ua Haujlwm Ua Haujlwm (WPM) yog qhov tso tawm ntawm cov txheej txheem no
