Lub zog nqa los ntawm nthwv dej yog proportional rau nws amplitude squared. Hauv electromagnetic tsis, qhov amplitude yog qhov siab tshaj plaws lub zog ntawm hluav taws xob thiab sib nqus teb.
Ntawm no, dab tsi yog qhov siab tshaj plaws hluav taws xob hluav taws xob hauv hluav taws xob nthwv dej?
Cov siab kawg Sib nqus teb zog ntawm ib electromagnetic teb Luas 5 x 10 - 6 T.
Ib yam li ntawd, lub zog hluav taws xob yog dab tsi? Electric teb zog yog quantitative nthuav qhia ntawm cov kev siv zog ntawm ib hluav taws xob teb ntawm qhov chaw tshwj xeeb. Tus qauv ntsuas yog volt ib 'meter' (v / m lossis v · m -1).
Tsis tas li ntawd, tus qauv ntawm lub zog hluav taws xob yog dab tsi?
SI unit ntawm hluav taws xob teb zog yog newtons Ib coulomb (N / C) los yog volts ib 'meter' (V / m). Lub zog uas tau ntsib los ntawm qhov kev sim me me heev q muab tso rau hauv thaj chaw E hauv lub tshuab nqus tsev yog muab los ntawm E = F / q, qhov twg F yog lub zog tau ntsib.
Yuav ua li cas koj xam electromagnetic zog?
Qhov kev sib raug zoo no yog muab los ntawm Planck's kev sib npaug E = hν, qhov twg E yog tus zog per photon, ν yog qhov zaus ntawm photon, thiab h yog Planck qhov tas li.

Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
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
Lub zog hluav taws xob hauv hluav taws xob yog dab tsi?
Los ntawm Wikipedia, dawb encyclopedia. Cov khoom siv hluav taws xob semiconductor yog cov khoom siv hluav taws xob siv hluav taws xob siv los hloov lossis hloov hluav taws xob hauv hluav taws xob hluav taws xob (piv txwv li hauv lub tshuab hluav taws xob hloov hluav taws xob). Cov cuab yeej zoo li no tseem hu ua lub tshuab hluav taws xob lossis, thaum siv hauv kev sib xyaw ua ke, lub zog IC
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
