X-ray paub – Puas X-Rays Phem Rau Koj?– https://hv-caps.biz
X-rays yog ib qho zoo ntxiv rau lub ntiaj teb tshuaj; lawv cia cov kws kho mob sib tham hauv ib tus neeg mob yam tsis muaj kev phais txhua. Nws yooj yim dua thiab muaj kev nyab xeeb dua los saib cov pob txha tawg uas siv X-rays dua li qhib tus neeg mob.
Tab sis X-rays kuj tuaj yeem tsim teeb meem. Nyob rau hauv cov hnub thaum ntxov ntawm X-ray science, ntau tus kws kho mob yuav nthuav tawm cov neeg mob thiab lawv tus kheej mus rau kab teeb rau lub sijhawm ntev. Thaum kawg, cov kws kho mob thiab cov neeg mob pib mob hluav taws xob, thiab cov neeg kho mob paub tias muaj qee yam tsis raug.
Qhov teeb meem yog tias X-rays yog ib hom hluav taws xob ionizing. Thaum lub teeb ib txwm tsoo lub atom, nws tsis tuaj yeem hloov lub atom hauv txhua txoj kev tseem ceeb. Tab sis thaum X-ray tsoo lub atom, nws tuaj yeem tsoo cov electrons tawm ntawm lub atom los tsim ib qho ion, ib qho hluav taws xob atom. Dawb electrons ces sib tsoo nrog lwm cov atoms los tsim ntau ions.
Ib qho ion tus nqi hluav taws xob tuaj yeem ua rau cov tshuaj tsis zoo hauv cov hlwb. Ntawm lwm yam, tus nqi tuaj yeem rhuav tshem DNA chains. Ib lub xov tooj ntawm tes nrog DNA tawg yuav tuag lossis DNA yuav tsim kev hloov pauv. Yog tias ntau lub hlwb tuag, lub cev tuaj yeem tsim ntau yam kab mob. Yog tias DNA hloov pauv, lub xov tooj ntawm tes yuav ua mob qog noj ntshav, thiab mob qog noj ntshav yuav kis tau. Yog tias qhov kev hloov pauv nyob hauv cov phev los yog lub qe qe, nws yuav ua rau muaj kev yug me nyuam. Vim tias tag nrho cov kev pheej hmoo no, cov kws kho mob siv X-rays niaj hnub no.
Txawm tias muaj cov kev pheej hmoo no, X-ray scanning tseem yog ib qho kev xaiv zoo dua li kev phais. X-ray tshuab yog cov cuab yeej tseem ceeb hauv cov tshuaj, nrog rau cov cuab yeej cuab tam hauv kev ruaj ntseg thiab kev tshawb fawb tshawb fawb. Lawv yog cov tiag tiag ib qho ntawm feem ntau inventions ntawm tag nrho cov sij hawm.
