Cov rods tswj tau siv nyob rau hauv nuclear reactors los tswj lub fission tus nqi ntawm uranium los yog plutonium. Lawv cov khoom muaj xws li tshuaj lom neeg xws li boron , cadmium, silver, los yog indium, uas muaj peev xwm nqus tau ntau neutrons yam tsis muaj lawv tus kheej fissioning.
Ua raws li qhov kev pom no, peb tuaj yeem tswj cov tshuaj tiv thaiv nuclear hauv lub tshuab fais fab li cas?
Sab hauv reactor Lub nkoj, cov pas nrig roj tau muab tso rau hauv dej uas ua haujlwm ua ob qho tib si coolant thiab moderator. Tus neeg nruab nrab pab qeeb cov neutrons uas tsim los ntawm fission los txhawb nqa chain reaction . Tswj rods tuaj yeem muab tso rau hauv reactor core kom txo cov tshuaj tiv thaiv tus nqi lossis rho tawm kom nws nce.
Tom qab, lo lus nug yog, dab tsi pib muaj kev tawm tsam nuclear? Yuav kom pib feem ntau fission cov tshuaj tiv thaiv , lub atom yog bombarded los ntawm ib tug neutron los tsim ib tug unstable isotope, uas undergoes fission. Thaum cov neutrons raug tso tawm thaum lub sij hawm fission, lawv muaj peev xwm pib ib tug saw tshuaj tiv thaiv ntawm nruam fission uas sustains nws tus kheej.
Kuj nug, uas yog siv los ua coolant hauv nuclear reactor?
A nuclear reactor coolant yog a coolant siv tshem tawm cov cua sov los ntawm nuclear reactor core thiab hloov mus rau hluav taws xob generators thiab ib puag ncig. Carbon dioxide, Helium thiab kua Sodium tuaj yeem ua tau siv ua coolant hauv a nuclear reactor.

Tus kws tshaj lij hluav taws xob puas tuaj yeem ua tus kws kho hluav taws xob?
Koj tuaj yeem tau txais koj pib nrog tsawg asatwo-xyoo Associate's degree thiab ntawv pov thawj los ntawm AmericanRegistry of Radiologic Technologists. Ntau yam rad techspursueradiology tshwj xeeb, xws li mammography. Lwm tus txiav txim siab ntxiv lawv txoj haujlwm los ntawm kev rov qab mus rau tsev kawm ntawv los ua tus kws kho mob
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
Dab tsi tuaj yeem siv los txiav txim siab tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed?
Enzyme catalysis yog kuaj pom los ntawm kev ntsuas qhov pom ntawm cov khoom lossis ploj ntawm cov reactants. Txhawm rau ntsuas qee yam, koj yuav tsum muaj peev xwm pom nws. Enzyme assay yog cov kev ntsuam xyuas tsim los ntsuas kev ua haujlwm ntawm enzyme los ntawm kev ntsuas qhov kev hloov pauv hauv cov ntsiab lus ntawm cov tshuaj uas pom tau
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
