INTENSIFYING Thiab fluorescent XOV XWM Thiab XERORADIOGRAPHY
Rau cov yeeb yaj kiab nthuav tawm thaum tsis muaj cov ntxaij vab tshaus cov cuam tshuam nyiaj bromide crystals raug faib thoob plaws tag nrho cov tuab ntawm emulsion thiab kev loj hlob ntev yog xav tau yog tias tag nrho cov no yuav tsum tau hloov mus rau hauv nyiaj.
Raws li, yuav ua li cas rau silver bromide nyob rau hauv lub teeb?
Thaum twg nyiaj bromide los yog AgBr khaws cia rau hauv tshav ntuj muaj tshuaj tiv thaiv tshwm sim . Chemical decomposition hu ua photo chemical reaction tshwm sim qhov twg nyiaj bromide hloov mus ua grey. Thaum peb khaws cov nyiaj bromide Nyob rau hauv tshav ntuj ces tom qab 2 mus rau 3 teev nws los ua Grey xim.
Vim li cas thiaj siv cov ntxaij vab tshaus siv hauv hluav taws xob? Intensifying cov ntxaij vab tshaus yog siv hauv x-ray cassette rau ua kom hnyav cov nyhuv ntawm cov x-ray photon los ntawm kev tsim ntau lub teeb photons. Nws txo qhov tshaj yuav tsum tau tsim ib qho kev ceev thiab chaw pib txo tus neeg mob koob ho.
Tsis tas li ntawd, cov ntxaij vab tshaus uas ua rau muaj zog yog dab tsi?
Ib intensifying npo yog ib daim ntawv yas coated nrog cov khoom siv fluorescent hu ua phosphor. Phosphors yog cov khoom siv uas hloov photon zog rau lub teeb.
Silver bromide siv rau dab tsi?
Siv : Vim nws lub teeb rhiab qhov xwm txheej, cov ntawv thov tseem ceeb ntawm nyiaj bromide yog nyob rau hauv kev yees duab. Nws yog siv nyob rau hauv kev yees duab films thiab daim hlau. Nws kuj yog siv rau infrared daim ntaub ntawv, rau lub teeb rhiab tsom iav, thiab semiconductors.

Puas yog HClO muaj zog lossis tsis muaj zog?
HClO yog ib qho kua qaub raws li nws muaj cov proton uas nws tso tawm tab sis nws yog ib qho tsis muaj zog acid vim nws tsis yog ib qho acidamoung cov npe ntawm cov kua qaub muaj zog
Puas yog tag nrho cov minerals tsim muaj crystals?
Feem ntau cov minerals tshwm sim ib yam li cov muaju. Txhua lub siv lead ua muaj cov qauv zoo, sab hauv ntawm atoms, nrog rau txoj kev sib txawv ntawm kev kaw cov atoms tshiab rau hauv cov qauv ntawd kom rov ua dua thiab dua. Cov txheej txheem sab hauv ntawm atoms txiav txim siab tag nrho cov ntxhia hauv tshuaj thiab lub cev, suav nrog xim
Lub cev puas tuaj yeem muaj lub zog tsis muaj zog muab qhov laj thawj?
Teb thiab piav qhia: Lub cev tsis tuaj yeem muaj lub zog tsis muaj zog. Qhov no yog vim hais tias tsuas yog txav cov khoom havemomentum, thiab ib yam khoom nyob rau hauv motion ib txwm haskinetic
Hom kev sib txuas dab tsi muaj nyob hauv sodium bromide crystals?
Ionic bonds muaj nyob rau hauv sodium bromide crystals. Sodium bromide crystals yog soluble nyob rau hauv dej vim hais tias ntawm lawv sib xws polar yam ntxwv
Cov cuab yeej twg tuaj yeem siv los tsim cov cim thiab cov ntxaij vab tshaus?
Ib qho ntawm qhov txias tshaj plaws ntawm Ionic yog cov cuab yeej cuab tam uas lawv muab rau kev tsim tag nrho cov ntxaij vab tshaus thiab cov cim uas koj xav tau. Txawm hais tias koj tsis siv Ionic, nws yuav tsim nyog txhim kho tsuas yog siv cov cuab yeej no thiab tom qab ntawd hloov pauv cov ntxaij vab tshaus thiab cov cim rau koj qhov project tiag
