Qhov sib txawv tseem ceeb ntawm Bremsstrahlung thiab Cherenkov hluav taws xob yog qhov hluav taws xob Bremsstrahlung yog cov hluav taws xob uas tsim thaum lub teeb hluav taws xob nrawm nrawm thaum Cherenkov hluav taws xob yog qhov sib npaug ntawm qhov sib npaug ntawm lub suab nrov uas tau pom thaum cov khoom tawg tawg lub teeb thaiv hauv ib qho. medium.
Radiation yog qhov emission ntawm lub zog raws li electromagnetic nthwv dej los yog txav subatomic hais, tshwj xeeb tshaj yog muaj zog hais, uas ua rau ionization.
Dab tsi yog Bremsstrahlung Radiation?
Bremsstrahlung hluav taws xob cov hluav taws xob uas tau muab tawm los ntawm cov khoom siv hluav taws xob vim nws qhov nrawm los ntawm qhov hluav taws xob lossis lwm qhov hluav taws xob. Tus nqi them uas dhau mus nrawm ntawm no feem ntau yog ib qho hluav taws xob uas muaj qhov tsis zoo. Lwm qhov kev them nqi uas tuaj yeem ua rau lub tshuab hluav taws xob nrawm yog proton lossis atomic nucleus. Lub npe Bremsstrahlung originates los ntawm German lub ntsiab lus "braking radiation" - qhov no yog vim txoj kev uas electrons yog braked thaum lawv ntaus ib tug hlau phiaj.

Thaum tsim hom hluav taws xob no, qhov xwm txheej electrons yog "dawb", txhais tau hais tias cov electrons tsis raug khi rau ib qho atom lossis ion, ua ntej thiab tom qab lub braking. Ntxiv mus, lub spectrum ntawm hom hluav taws xob no yog tas mus li. Tsis tas li ntawd, yog tias lub zog ntawm qhov xwm txheej electrons siab txaus, lawv tawm X-rays tom qab lawv tau nres.
Ib qho piv txwv ntawm cov hluav taws xob Bremsstrahlung uas pom tau hauv lub qab ntuj khwb yog cov hluav taws xob uas los ntawm cov pa kub kub ntawm cov galaxy pawg.
Cherenkov Radiation yog dab tsi?
Cherenkov hluav taws xob yog ib hom hluav taws xob hluav taws xob hluav taws xob uas tawm thaum cov khoom siv hluav taws xob dhau los ntawm qhov nruab nrab dielectric ntawm qhov nrawm dua li theem tshaj tawm ntawm lub teeb hauv qhov nruab nrab. Feem ntau, cov nqi them uas peb xav txog ntawm no yog ib qho hluav taws xob. Lub ntsiab lus ntawm lo lus "theem tshaj tawm" yog qhov nrawm ntawm kev nthuav tawm ntawm nthwv dej hauv nruab nrab.

Ib qho piv txwv classic ntawm hom hluav taws xob no yog cov yam ntxwv xiav ci ntawm lub tshuab hluav taws xob hauv qab dej. Qhov laj thawj rau hom hluav taws xob no zoo ib yam li qhov ua rau lub suab nrov nrov - lub suab nrov tau hnov thaum nrawm dua lub suab txav tshwm sim. Cov hluav taws xob hluav taws xob no tau muaj npe tom qab tus kws tshawb fawb Pavel Cherenkov.
Qhov txawv ntawm Bremsstrahlung thiab Cherenkov Radiation yog dab tsi?
Radiation yog qhov emission ntawm lub zog raws li electromagnetic nthwv dej los yog txav subatomic hais, tshwj xeeb tshaj yog muaj zog hais uas ua rau ionization. Qhov sib txawv tseem ceeb ntawm Bremsstrahlung thiab Cherenkov hluav taws xob yog qhov hluav taws xob Bremsstrahlung yog cov hluav taws xob uas tsim thaum lub teeb hluav taws xob nrawm nrawm thaum Cherenkov hluav taws xob yog qhov sib npaug ntawm qhov sib npaug ntawm lub suab nrov uas tau pom thaum lub suab tawg tawg lub teeb ci hauv nruab nrab. Cov hluav taws xob uas los ntawm cov pa kub kub ntawm cov galaxy pawg yog ib qho piv txwv ntawm cov hluav taws xob Bremsstrahlung thaum lub teeb xiav xiav ntawm lub underwater nuclear reactor yog ib qho piv txwv ntawm Cherenkov hluav taws xob.
Ua raws li cov ntawv sau qhia ib sab ntawm qhov sib txawv ntawm Bremsstrahlung thiab Cherenkov hluav taws xob.
Summary – Bremsstrahlung vs Cherenkov Radiation
Bremsstrahlung thiab Cherenkov hluav taws xob yog ob hom hluav taws xob. Qhov sib txawv tseem ceeb ntawm Bremsstrahlung thiab Cherenkov hluav taws xob yog qhov hluav taws xob Bremsstrahlung yog cov hluav taws xob uas tsim thaum lub teeb hluav taws xob nrawm nrawm thaum Cherenkov hluav taws xob yog qhov sib npaug ntawm lub suab nrov uas tau pom thaum lub teeb tawg tawg lub teeb ci hauv nruab nrab.
