Zoo li cov khoom, Minerals, thiab qee yam khoom siv. Terbium dua yog ib qho ntawm ntau cov ntsiab lus hauv lub xov tooj (Nws lub cim yog "Tb"). Terbium yog siv nyob rau hauv Circuit Court boards thauj lub zog. Kub yog ib yam khoom thiab cov ntxhia hauv koj xov tooj.
Ua kom pom qhov no, Terbium siv hauv xov tooj li cas?
Ib tug mos, silvery hlau. Terbium yog siv dope calcium fluoride, calcium tungstate thiab strontium molybdate, tag nrho siv nyob rau hauv cov khoom siv solid-state. Nws kuj yog siv nyob rau hauv cov teeb hluav taws xob tsawg thiab cov teeb mercury.
Tsis tas li ntawd, cov ntsiab lus twg yog siv hauv xov tooj ntawm tes? Smartphones yog tsim los ntawm ib ncig ntawm 30 yam, suav nrog tooj liab , kub thiab nyiaj rau kev xaim thiab lithium thiab cobalt hauv lub roj teeb. Cov xim ci ntawm cov zaub yog tsim los ntawm cov khoom me me ntawm lub ntiaj teb tsis tshua muaj, suav nrog yttrium, terbium thiab dysprosium.
Ua raws li qhov xav tau, Terbium siv dab tsi?
Terbium yog siv li Ib qho dopant hauv calcium fluoride, calcium tungstate, thiab strontium molybdate, cov ntaub ntawv uas yog siv hauv Cov khoom siv hauv lub xeev, thiab ua cov khoom siv hluav taws xob ruaj khov ntawm cov roj hlwb uas ua haujlwm ntawm qhov kub siab, ua ke nrog ZrO2. Terbium kuj yog siv hauv alloys thiab hauv kev tsim cov khoom siv hluav taws xob.
Cov hlau tsis tshua muaj hauv ntiaj teb yog dab tsi hauv xov tooj ntawm tes?
Smartphones kuj muaj ntau yam tsawg ntiaj teb yam – cov ntsiab lus uas yog plentiful nyob rau hauv lub Lub ntiaj teb crust tab sis nyuaj heev rau kuv thiab rho tawm kev lag luam - suav nrog yttrium, lanthanum, terbium, neodymium, gadolinium thiab praseodymium.

Cov hlau tsis tshua muaj hauv ntiaj teb yog dab tsi hauv xov tooj ntawm tes?
Cov xov tooj smartphones kuj tseem muaj ntau yam ntawm lub ntiaj teb tsis tshua muaj - cov ntsiab lus uas muaj ntau nyob hauv lub ntiaj teb pob zeb tab sis nyuaj heev rau kuv thiab rho tawm kev lag luam - suav nrog yttrium, lanthanum, terbium, neodymium, gadolinium thiab praseodymium
Lub organelle twg ua haujlwm raws li qhov chaw xa ntawv ntawm lub xov tooj ntawm tes txheeb cov proteins thiab xa lawv mus rau lawv qhov chaw xav tau sab hauv lossis sab nraud ntawm tes?
Golgi Hais txog qhov no, dab tsi organelle yog lub luag haujlwm rau kev thauj mus los? endoplasmic reticulum (ER Qhov thib ob, cov proteins txav mus los ntawm lub cell li cas? Cov proteins txav mus los endomembrane system thiab raug xa tawm los ntawm lub ntsej muag trans ntawm Golgi apparatus nyob rau hauv thauj vesicles uas txav mus los cytoplasm thiab tom qab ntawd fuse nrog plasma membrane tso tawm protein ntau mus rau sab nraum lub cell .
Dab tsi ntawm lub xov tooj ntawm tes ua raws li qhov chaw tswj kev ua haujlwm ntawm tes?
Lub nucleus muaj cov ntaub ntawv genetic information (DNA) onspecial strands hu ua chromosomes. Function - Lub nucleus yog 'tswj chaw' ntawm lub xovtooj ntawm tes, rau cellmetabolism thiab kev yug me nyuam. Cov kab mob hauv qab no pom muaj nyob rau hauv cov nroj tsuag thiab tsiaj txhu
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Ib puag ncig ntawm ib lub xov tooj ntawm tes thiab cov kab mob cuam tshuam li cas ntawm cov noob caj noob ces?
Splicing ntawm mRNA nce tus naj npawb ntawm cov protein sib txawv uas lub cev muaj peev xwm tsim tau. Gene qhia yog tswj los ntawm cov proteins uas khi rau cov hauv paus hauv paus hauv DNA. Ib puag ncig ntawm ib lub xovtooj ntawm tes thiab ntawm lub cev muaj feem cuam tshuam rau cov noob caj noob ces
