Amorphous cov khoom khib nyiab muaj ob yam ntxwv. 1-Thaum cleaved los yog tawg, lawv tsim fragments nrog irregular, feem ntau nkhaus nto; thiab lawv muaj cov qauv tsis zoo thaum raug x-rays vim tias lawv cov khoom tsis tau teem rau hauv ib qho array tsis tu ncua. Ib qho amorphous, translucent khoom hu ua iav.
Tsis tas li ntawd, cov khoom ntawm amorphous solids yog dab tsi?
Cov no cov khoom khib nyiab yog stabilized los ntawm cov qauv tsis tu ncua ntawm lawv cov atoms. Lawv tus yam ntxwv khoom suav nrog cov ntsiab lus melting thiab boiling, cov duab geometric li niaj zaus, thiab lub ntsej muag tiaj tus thaum cleaved los yog sheared. Qee qhov piv txwv suav nrog sodium chloride, dej khov, hlau, thiab pob zeb diamond.
Ib tug kuj yuav nug, koj txhais li cas los ntawm amorphous tshuaj? Hauv physics thiab chemistry, amorphous yog ib lo lus siv los piav txog a khov kho uas ua tsis pom cov qauv crystalline. Thaum tej zaum yuav muaj kev txiav txim hauv zos ntawm cov atoms lossis molecules hauv ib qho amorphous khoom , tsis muaj kev txiav txim mus sij hawm ntev. Piv txwv ntawm amorphous Cov khoom muaj xws li qhov rais iav, polystyrene, thiab carbon dub.
Tsis tas li ntawd, dab tsi yog amorphous qauv?
Nyob rau hauv condensed teeb meem physics thiab cov ntaub ntawv science, ib amorphous (los ntawm Greek a, tsis muaj, morphé, zoo li, daim ntawv) lossis cov khoom tsis-crystalline yog cov khoom uas tsis muaj qhov ntev-ntev xaj uas yog tus yam ntxwv ntawm cov siv lead ua. Hauv qee phau ntawv qub, lo lus tau siv los ua ke nrog iav.
Dab tsi yog amorphous solids tuav ua ke los ntawm?
Ionic cov khoom khib nyiab zoo ib yam li network cov khoom khib nyiab nyob rau hauv ib txoj kev: Tsis muaj cov molecules txawv. Tab sis tsis yog atoms tuav ua ke los ntawm covalent bonds, ionic cov khoom khib nyiab yog tsim los ntawm qhov zoo thiab tsis zoo them ions tuav ua ke los ntawm ionic daim ntawv cog lus.

Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Qhov twg ntawm cov no yog tus yam ntxwv ntawm txhua yam muaj sia?
Cov yam ntxwv no yog lub koom haum ntawm tes, kev yug me nyuam, metabolism, homeostasis, heredity, teb rau stimuli, kev loj hlob thiab kev loj hlob, thiab adaptation los ntawm evolution. Qee yam, xws li tus kab mob, pom tsuas yog qee yam ntawm cov yam ntxwv no thiab yog li ntawd, tsis muaj sia nyob
Dab tsi ntawm lub cev nta yog cov yam ntxwv ntawm cov ntug dej hiav txwv ntawm Texas?
Texas 'Gulf Coastal Plains yog sab hnub poob txuas ntxiv ntawm ntug hiav txwv tiaj tiaj txuas los ntawm Dej Hiav Txwv Atlantic mus dhau Rio Grande. Nws cov yam ntxwv dov mus rau toj roob hauv pes npog nrog kev loj hlob hnyav ntawm ntoo thuv thiab tawv ntoo txuas mus rau East Texas
Peb lub neej yog dab tsi thiab lawv cov yam ntxwv tshwj xeeb yog dab tsi?
Peb lub npe suav nrog: Archaea - cov npe qub tshaj plaws, cov kab mob qub. Cov kab mob - tag nrho lwm cov kab mob uas tsis suav nrog hauv Archaea domain. Eukarya - tag nrho cov kab mob uas muaj eukaryotic los yog muaj cov kab mob sib txuas thiab cov nuclei
