Hauv optical mineralogy thiab petrography, a nyias seem (los yog petrographic nyias seem ) yog ib qho chaw kuaj mob ntawm pob zeb, pob zeb hauv av, av, lauj kaub tais diav, pob txha, lossis txawm tias cov qauv hlau siv nrog lub polarizing petrographic microscope, electron microscope thiab electron microprobe.
Ib yam li ntawd ib tug yuav nug, ua li cas koj ua ib tug nyias seem?
Cov txheej txheem no yog ib qho yooj yim:
- Xyuas kom cov seem huv si thiab tsis muaj grit lossis av.
- Muab tso rau ntawm lub phaj kub.
- Sib tov ib pawg me me ntawm epoxy thiab hardener.
- Muab ib qho me me ntawm epoxy tso rau ntawm ntu.
- Muab ib daim npog plam ntawm qhov poob.
- Txav mus rau ib ncig kom tshem tawm npuas thiab npog tag nrho cov seem.
- Cia nws kho.
Kuj Paub, koj tuaj yeem qhia tau li cas yog biotite nyias? Hauv nyias seem , biotite nthuav tawm me ntsis nyem thiab daj ntseg mus rau tob greenish xim av los yog xim av xim, nrog rau nruab nrab mus rau muaj zog pleochroism. Biotite muaj lub siab birefringence uas tuaj yeem npog ib nrab los ntawm nws cov xim sib sib zog nqus.
Yog li ntawd, vim li cas geologists ua cov ntu nyias?
Nyias ntu cia peb saib cov ntxhia hauv ntau yam sib txawv. Qhov no tso cai rau peb pom cov ntxhia pob zeb tshiab thiab pab nrog kev txheeb xyuas cov ntxhia. Nws yog tus nqi qis atomic sojntsuam.
Koj piav qhia txog ntu nyias li cas?
Hauv optical mineralogy thiab petrography, a nyias seem (los yog petrographic nyias seem ) yog ib qho chaw kuaj mob ntawm pob zeb, pob zeb hauv av, av, lauj kaub tais diav, pob txha, lossis txawm tias cov qauv hlau siv nrog lub polarizing petrographic microscope, electron microscope thiab electron microprobe.

Puas yog glycerol xav tau daim nyias nyias nyias kom hla daim nyias nyias?
Glycerol yog lipid soluble yog li nws diffuses los ntawm yooj yim diffusion ncaj qha los ntawm lub cell membrane thaum cov piam thaj yog ib tug polar molecule yog li nws diffuses los ntawm kev yooj yim diffusion uas txhais tau hais tias nws xav tau ib tug channel protein ua hauj lwm thiab qhov no txhais tau tias thaj chaw saum npoo rau cov piam thaj kom nkag mus yog tsawg dua. tshaj ib qho rau glycerol
Cov txheej nyias nyias chromatography yog dab tsi thiab nws ua haujlwm li cas?
Nyias-txheej chromatography (TLC) yog ib qho txheej txheem chromatography siv los cais cov khoom sib xyaw uas tsis yog-volatile. Tom qab cov qauv tau siv rau ntawm lub phaj, cov kuab tshuaj los yog cov kuab tshuaj sib tov (lub npe hu ua lub sijhawm txawb) yog kos rau ntawm lub phaj ntawm capillary nkaus
Dab tsi yog ib qho laj thawj uas ib lub xovtooj yuav tsum tau tswj cov dej ntws hla ntawm daim nyias nyias?
Dab tsi yog ib qho laj thawj uas lub cell yuav tsum tswj cov flowacross daim nyias nyias? Lub nucleus yuav tsum coj mus rau hauv DNA. Lub cell xav tau cov pa roj carbon dioxide ua lub zog. Cov cytoplasmneeds coj cov organelles
Dab tsi yog cov haujlwm sib txawv ntawm daim nyias nyias?
Kev ua haujlwm ntawm Membrane Proteins Membrane proteins tuaj yeem ua haujlwm ntau yam haujlwm tseem ceeb: Kev sib tshuam - Ua haujlwm txuas thiab koom nrog ob lub hlwb ua ke. Enzymes - Kho rau daim nyias nyias localises metabolic txoj kev. Tsheb thauj mus los - Lub luag haujlwm rau kev yooj yim diffusion thiab nquag thauj
Lub luag haujlwm ntawm daim nyias nyias thauj proteins yog dab tsi?
Kev thauj cov proteins ua lub qhov rooj rau ntawm tes, pab qee cov molecules hla rov qab mus rau hauv cov plasma membrane, uas nyob ib puag ncig txhua lub cell. Nyob rau hauv passive thauj molecules txav los ntawm ib cheeb tsam ntawm siab concentration mus rau qhov chaw uas tsis muaj concentration
