Ntawm 83 ruaj khov thiab tsis yog - radioactive cov ntsiab lus nyob rau hauv lub periodic rooj, tsawg kawg yog 70 tuaj yeem pom nyob rau hauv smartphones . Raws li qhov zoo tshaj plaws muaj nuj nqis, tag nrho ntawm 62 ntau hom hlau mus rau hauv nruab nrab lub xov tooj ntawm tes, nrog dab tsi hu ua lub ntiaj teb tsis tshua muaj hlau ua lub luag haujlwm tseem ceeb tshwj xeeb.
Ua raws li qhov no saib, cov ntsiab lus dab tsi hauv lub smartphone?
Smartphones yog tsim los ntawm ib ncig ntawm 30 cov ntsiab lus , 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 cov ntsiab lus , suav nrog yttrium, terbium thiab dysprosium.
Tom qab ntawd, lo lus nug yog, cov xov tooj ntawm tes puas muaj cov khoom siv hluav taws xob? Xov tooj ntawm tes siv tsis-ionizing hluav taws xob , uas txawv ntawm ionizing hluav taws xob ntawm x-rays thiab cov khoom siv hluav taws xob hauv qhov ntawd tsis yog muaj txaus lub zog los khob ib ncig-los yog ionize-electrons los yog hais nyob rau hauv atoms.
Kuj kom paub yog, puas yog txhua lub xov tooj smartphones siv tib lub ntiaj teb tsis tshua muaj hlau?
Cov no tsis tshua muaj - ntiaj teb hlau suav nrog scandium thiab yttrium, thiab cov ntsiab lus 57–71. Cov ntsiab lus 57–71 yog lub npe hu ua lanthanides, vim lawv pib nrog lub caij lanthanum. Tsis tshua muaj - ntiaj teb hlau yog tsis yog xwb siv hauv smartphones tab sis nyob rau hauv ntau lwm yam khoom siv high-tech, ib yam nkaus.
Yam tsawg kawg yog dab tsi hauv xov tooj ntawm tes?
Smartphones kuj muaj ntau yam tsawg ntiaj teb cov ntsiab lus - cov ntsiab lus uas muaj ntau nyob rau hauv 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.

Vim li cas kuv lub tshuab hluav taws xob tsis tsim hluav taws xob?
Feem ntau ua rau lub tshuab hluav taws xob portable tsis tsim hluav taws xob yog los ntawm kev poob ntawm cov hlau nplaum seem. Generators ua hauj lwm los ntawm kev txav hluav taws xob conductors los ntawm magnetic teb. Koj lub tshuab hluav taws xob tsis muaj hlau nplaum. Thaum cov hlau nplaum seem ploj lawm, lub tshuab hluav taws xob yuav tsis muaj zog thaum pib
Hom hluav taws xob hluav taws xob muaj nyob hauv tsheb li cas?
Lub tshuab hluav taws xob ntawm lub tsheb yog lub kaw lus kaw nrog lub zog ywj pheej ntawm lub roj teeb. Nws ua hauj lwm ntawm ib feem me me ntawm lub hwj chim ntawm ib tsev neeg circuit
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
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
