Dej creeps up daim ntawv vim kev ua ntawm capillary. Qhov no yog thaum sib txuas ntawm cov kua molecules rau lawv tus kheej yog tsawg dua qhov attraction rau lwm yam khoom ntawm molecules yog kov. Cov sodium bitartrate muaj sodium ion, peb pawg hydroxyl, thiab ob daim ntawv cog lus ob npaug.
Kuj paub yog, dab tsi yuav tshwm sim thaum lub sij hawm hnyav tsiv teb tsaws ntawm daim ntawv?
Raws li cov kuab tshuaj maj mam mus up daim ntawv , cov khoom sib txawv ntawm cov kua roj vanish sib txawv ntawm cov nqi sib txawv thiab cov khoom sib xyaw tau muab cais ua cov xim sib txawv. Daim duab qhia tias lub phaj yog dab tsi muaj peev xwm zoo li tom qab lub kuab tshuaj tau tsiv mus yuav luag rau saum.
Tom qab ntawd, lo lus nug yog, vim li cas cov xim sib cais hauv chromatography? Cov txheej txheem ntawm chromatography cais cov molecules vim qhov sib txawv solubilities ntawm cov molecules nyob rau hauv ib qho kev xaiv hnyav. Cov kuab tshuaj nqa cov yaj pigments raws li nws txav mus rau daim ntawv. Cov pigments yog nqa ntawm tus nqi sib txawv vim lawv tsis sib npaug zos soluble.
Ib sab saum toj no, tus nqi RF piav qhia txog qib microscopic Vim li cas qhov no tseem ceeb?
Cov Rf nqi piav qhia ntawm a microscopic theem piav qhia txog affinity ntawm ib tug solute rau qhov nruab nrab txhawb piv rau nws nyiam mus nqa nrog los ntawm cov hnyav. Nws yog tseem ceeb vim nws yog qhov kev ncua deb mus los ntawm cov qauv muab faib los ntawm qhov kev ncua deb mus los ntawm cov kuab tshuaj pem hauv ntej hauv chromatography.
Polarity cuam tshuam li cas ntawm daim ntawv chromatography?
Polarity muaj qhov loj cuam tshuam ntawm yuav ua li cas attracted ib tug tshuaj rau lwm yam tshuaj. Qhov loj dua qhov sib txawv, ntau dua polar ib molecule. Koj yuav pom tias thaum koj nce qhov polarity ntawm cov kuab tshuaj, tag nrho cov Cheebtsam ntawm qhov sib tov txav nrawm dua thaum koj chromatography kev sim.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Yuav ua li cas koj nthuav qhia cov txheeb cais nyob rau hauv ib daim ntawv qhia?
Cov txiaj ntsig piav qhia suav nrog ib lub rooj nrog cov ntaub ntawv txheeb xyuas tsim nyog xws li. qhov nruab nrab, hom, nruab nrab, thiab tus qauv sib txawv. Cov ntaub ntawv piav qhia yuav tsum muaj feem xyuam rau lub hom phiaj ntawm kev kawm; nws yuav tsum tsis txhob suav nrog rau lub hom phiaj ntawm nws. Yog tias koj tsis mus siv hom nyob qhov twg, tsis txhob suav nrog nws
Vim li cas thiaj tseem ceeb rau cov kws qhia ntawv kom kawm txog morphology?
Kev kawm morphology pab cov tub ntxhais kawm rhuav tshem cov morphemes thiab txiav txim siab lawv lub ntsiab lus thiab nce lawv cov lus. Kev nkag siab txog morphology pab npaj cov tub ntxhais kawm mus rau qib tom ntej thiab nce qib kev nyeem ntawv thiab kev sau ntawv
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
Koj piav qhia txog daim ntawv qhia topographic li cas?
Daim duab qhia chaw saum toj saud feem ntau yog daim ntawv qhia loj loj uas piav qhia txog lub cev thiab tus txiv neej tsim ntawm toj roob hauv pes; thiab muaj qhov txawv txav los ntawm qhov pom ntawm cov kab contour uas qhia txog kev nthuav dav hauv av nyem ntawm thaj av
