Ib qho khoom siv ncej yog ib kem lossis ncej siv los txhawb nqa cov kab hluav taws xob siv hluav taws xob thiab ntau yam kev siv pej xeem, xws li hluav taws xob cable, fiber optic cable, thiab lwm yam khoom siv xws li transformers thiab txoj kev teeb.
Khaws qhov no hauv kev xav, dab tsi yog tus ncej hauv cov lus hluav taws xob?
Ncej: Ib qho hloov ncej hais txog tus naj npawb ntawm cov kab hluav taws xob sib cais uas qhov hloov pauv tswj. Ib leeg- ncej hloov tswj tsuas yog ib lub voj voog. Ib ob- ncej switch controls ob cais circuits. Yog li, ob- ncej switching muaj peb terminals. Ib qho ntawm cov terminals yog hu ua lub davhlau ya nyob twg.
3 Pole txhais li cas hauv cov lus hluav taws xob? 3 - tus ncej tias cov khoom siv ntsaws yog earthed thiab nws ib txwm muaj peb pins, uas ob yog siv los hloov cov tam sim no thiab ib qho yog siv los tiv thaiv tus kheej. Hauv ntau lub tebchaws hauv ntiaj teb, 2- ncej mains qhov (socket) tau hloov nrog 3 - ncej earthed sockets uas tuaj yeem txais ob qho tib si 2- ncej thiab 3 - ncej plugs.
Xav txog qhov no, dab tsi yog ncej hauv hluav taws xob lub cev muaj zog?
Ncej yog cov qauv ntawm lub stator uas lub teb windings raug mob. Kuj ncej muaj txiaj ntsig zoo hauv kev sib txuas cov flux tsim hauv stator vim kev hloov pauv hauv curremt hauv stator winding rau rotor windings. Ncej yeej ib txwm txawm nyob rau hauv tus lej thiab yog alternated sab qaum teb thiab sab qab teb ncej.
4 Pole txhais li cas hauv cov lus hluav taws xob?
Nws pib txhais tau tias tas ib hluav taws xob tshuab (lub cev muaj zog lossis generator) muaj plaub Sib nqus ncej raws li qhia hauv ntu ntu no: [1] Muaj plaub Sib nqus ncej ntawm lub rotor (lub puab sab uas tig nrog lub ncej): ob sab qaum teb ncej thiab ob sab qab teb ncej.

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
Tus qauv ntawm hluav taws xob hluav taws xob yog dab tsi?
Lub zog txuam nrog ib qho photon yog muab los ntawm E = h ν qhov twg E yog lub zog (SI units ntawm J), h yog Planck qhov tas li (h = 6.626 x 10–34 J s), thiab ν yog qhov zaus ntawm cov hluav taws xob (SI units ntawm s-1 lossis Hertz, Hz) (saib daim duab hauv qab no)
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 yog qhov txawv ntawm tus kws tshaj lij hluav taws xob thiab tus kws tshaj lij hluav taws xob?
Qhov sib txawv tseem ceeb ntawm cov kws tshaj lij hluav taws xob thiab cov kws tshaj lij xov tooj cua yog lawv cov qib kev kawm.Lawv yuav tau dhau ob qho kev xeem ntawv pov thawj RN thiab theradiology cov kws saib xyuas neeg mob daim ntawv pov thawj xws li ib tus tswj hwm los ntawm Lub Koom Haum rau Radiologic & ImagingNursing
