Qhov sib txawv tseem ceeb ntawm sedimentation thiab flotation yog tias sedimentation cuam tshuam nrog kev sib haum xeeb ntawm cov khoom seem hauv qab ntawm lub thawv, whereas flotation piav txog qhov txheeb ze ntawm cov khoom.
Sedimentation yog txheej txheem ntawm kev daws lossis muab tso ua sediment. Flotation yog qhov ua ntawm ntab hauv cov kua lossis roj. Yog li ntawd, sedimentation thiab flotation yog txawv kiag li phenomena uas piav txog kev tawm tsam txhais.
Dab tsi yog Sedimentation?
Sedimentation yog txheej txheem ntawm kev daws lossis muab tso ua sediment. Peb tuaj yeem piav qhia nws raws li qhov xav tau ntawm cov khoom hauv qhov raug tshem tawm kom tawm ntawm cov kua dej. Qhov no tshwm sim vim yog cov lus teb uas cov khoom no tawm tsam lawv txoj kev txav los ntawm cov kua.
Daim duab 01: Tsim cov Sediments
Lub zog uas ua rau cov khoom no tuaj yeem yog lub ntiajteb txawj nqus, centrifugal acceleration, lossis electromagnetism. Thaum cov khoom hnyav dua nyob rau hauv qab ntawm cov kua dej, peb tuaj yeem nchuav cov kua dej saum cov pob zeb, cais cov sediment ntawm cov kua.
Hauv kev siv tshuaj, sedimentation yog qhov tseem ceeb hauv kev ntsuas qhov loj ntawm cov molecules loj uas muaj lub zog ntawm lub ntiajteb txawj nqus augmented nrog lub zog centrifugal hauv ib qho ultracentrifuge.
Flotation yog dab tsi?
Flotation yog qhov ua ntawm ntab hauv cov kua lossis roj. Flotation tshwm sim los ntawm buoyancy los yog upthrust. Nws yog lub zog nce siab uas tau tawm los ntawm cov kua dej uas tawm tsam rau qhov hnyav ntawm cov khoom uas yog tag nrho lossis ib nrab rau hauv cov kua. Yog li ntawd, peb tuaj yeem txhais flotation raws li qhov tshwm sim uas cuam tshuam nrog kev txheeb ze ntawm cov khoom.
Flotation tseem ceeb heev hauv kev xaiv cov khoom sib cais, cov kua dej, tshuaj lom neeg, ions, lossis cov khoom siv lom neeg los ntawm cov kua dej ntau, nyob ntawm lawv cov khoom nto. Piv txwv li, nyob rau hauv cov kua-khoom sib cais tshuab, flotation yog pab tau los cais cov khib nyiab nyob rau hauv ncua kev kawm ntawv uas tau zoo los ntawm lawv daim ntawv cog lus rau roj npuas. Cov txheej txheem no yog qhov tseem ceeb hauv kev tshem tawm cov khoom hauv qhov loj ntawm 10 txog 200 micrometers zoo.
Daim duab 02: Ib lub npib hlau ntab ntab saum Mercury
Tsis tas li ntawd, thaum ib qho khoom txav qhov hnyav ntawm cov dej uas sib npaug ntawm qhov hnyav ntawm qhov khoom ntawd, cov khoom yuav ntab. Qhov no yog lub hauv paus ntsiab lus ntawm flotation. Nws tuaj yeem piav qhia tias yog ib qho khoom ntab uas txav qhov hnyav ntawm cov kua dej uas sib npaug ntawm tus kheej qhov hnyav ntawm cov khoom.
Qhov txawv ntawm Sedimentation thiab Flotation yog dab tsi?
Sedimentation yog txheej txheem ntawm kev daws lossis muab tso ua sediment. Flotation yog qhov ua ntawm ntab hauv cov kua lossis roj. Qhov sib txawv tseem ceeb ntawm sedimentation thiab flotation yog tias sedimentation cuam tshuam nrog kev sib haum xeeb ntawm cov khoom seem hauv qab ntawm lub thawv, whereas flotation piav txog qhov txheeb ze ntawm cov khoom. Kev tsim cov av hauv qab ntawm lub pas dej yog ib qho piv txwv ntawm sedimentation, thaum lub flotation ntawm nplooj qhuav ntawm tus dej ntws dej yog ib qho piv txwv ntawm flotation.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm sedimentation thiab flotation hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Sedimentation vs Flotation
Sedimentation thiab flotation yog txawv kiag li phenomena uas piav txog kev tawm tsam. Qhov sib txawv tseem ceeb ntawm sedimentation thiab flotation yog tias sedimentation cuam tshuam nrog kev sib haum xeeb ntawm cov khoom seem hauv qab ntawm lub thawv, whereas flotation piav txog qhov txheeb ze ntawm cov khoom.
