Kev Taw Qhia Tshwj Xeeb rau Kev Txawj Ntse ntawm Ionic Infrared Thermometer
Lub ntsuas kub infrared muaj lub ionization chamber, uas siv cov khoom siv hluav taws xob tsim hluav taws xob - americium 241 (Am241), nrog rau kev siv ntawm microcuries. Nws yog feem ntau nyob rau hauv equilibrium nrog ib tug hluav taws xob teb. Thaum cov pa luam yeeb nkag mus rau hauv ionization chamber, qhov zoo thiab qhov tsis zoo ions ionize, cuam tshuam qhov kev txav mus los ntawm cov khoom siv. Raws li qhov tshwm sim ntawm cov hluav taws xob hluav taws xob, txhua tus txav mus rau qhov zoo thiab qhov tsis zoo electrodes, cuam tshuam qhov sib npaug thiab tam sim no ntawm cov ionization chambers, Qhov voltage yuav hloov. Lub ion infrared tus pas ntsuas kub yog ib qho cuab yeej uas hnov qhov kev hloov pauv tam sim no ntawm cov pa luam yeeb los ntawm kev hloov hluav taws xob los ntawm lub ionization chamber sib npaug rau cov pa taws rhiab heev. Tom qab ntawd lub microscopic manifestation yog qhov sib ntxiv ntawm qhov sib npaug ntawm cov ionization chamber ua rau muaj qhov nce ntawm qhov hluav taws xob ntawm ob sab ntawm lub chamber, yog li txiav txim siab qhov xwm txheej ntawm cov pa taws hauv huab cua.
Cov ion hom infrared tus pas ntsuas kub siv cov lej ntawm cov khoom siv hluav taws xob hluav taws xob americium 241 sab hauv. Vim tias lub ntsuas kub lub cev yog npog los ntawm lub plhaub hlau, hluav taws xob yuav tsis xau, thiab cov neeg siv tuaj yeem siv nws nrog kev ntseeg siab. Tsis tas li ntawd, nws cov hluav taws xob hluav taws xob tsuas yog siv 55 feem pua ntawm NIS-09C, yog li cov teb chaws uas txwv kev siv hluav taws xob hluav taws xob kuj tuaj yeem siv nrog kev ntseeg siab. Ntxiv mus, cov khoom siv ko taw thiab cov yam ntxwv ntawm qhov ntsuas kub no hloov pauv tau nrog cov khoom lag luam los ntawm lwm lub tuam txhab. Tom qab xaiv cov hluav taws xob hluav taws xob tsawg thiab tsim nyog nthuav dav lub ionization chamber, qhov sib npaug ntawm qhov hluav taws xob yuav ruaj khov dua thaum ntxuav ntawm cov dej noo, zoo heev txo tus nqi ceeb toom tsis tseeb. Ionic infrared tus pas ntsuas kub yog tus ntsuas kub siab tshaj thiab txhim khu kev qha, dav siv hauv ntau lub tswb hluav taws xob, nrog kev ua haujlwm zoo tshaj rau cov roj hluav taws xob tiv thaiv hom hluav taws kub tswb.
Kev sib piv ntawm photoelectric pa taws tswb thiab ion infrared tus pas ntsuas kub:
Muaj ib qho kev tshawb nrhiav kho qhov muag nyob rau hauv lub photoelectric pa taws tswb, uas yog nruab nrog ib lub raj infrared. Thaum tsis muaj pa luam yeeb, lub raj xa hluav taws xob tsis tuaj yeem tau txais lub teeb infrared tshaj tawm los ntawm lub raj xa hluav taws xob infrared. Thaum cov pa luam yeeb nkag mus rau hauv qhov chaw tshawb pom qhov muag, nws refracts thiab xav txog, thiab lub raj txais tau txais lub teeb infrared. Lub tswb hluav taws xob ntse txiav txim siab seb qhov chaw pib tau dhau lawm, thiab yog tias nws tau dhau lawm, lub tswb yuav raug tshaj tawm. Lub tswb ion pa luam yeeb yuav tsum muaj kev paub ntau dua ntawm cov pa luam yeeb me me thiab tuaj yeem teb tus kheej rau ntau hom pa luam yeeb; Txawm li cas los xij, lub ntsej muag rau lub ntsej muag hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob muaj qhov ua kom pom tseeb ntawm cov pa taws loj me ntsis, thiab cov lus teb tsis zoo rau cov pa luam yeeb grey thiab dub. Thaum hluav taws kub hnyiab tshwm sim, muaj cov pa taws me me hauv huab cua ntau dua, thaum lub sij hawm smoldering teev, muaj cov pa taws loj dua nyob rau hauv cov huab cua. Yog tias hluav taws tawg tawm thiab muaj ntau qhov me me ntawm cov pa taws, lub tswb ion pa taws yuav ceeb toom ua ntej tshaj li lub tswb hluav taws xob hluav taws xob. Ob hom kev ceeb toom pa taws no tsis nyob ze rau txhua lub sijhawm, tab sis qhov txuas ntxiv ntawm cov hluav taws kub no nrawm heev. Nws raug nquahu kom nruab ion pa taws tswb nyob rau hauv cov chaw zoo li no. Tom qab lwm hom hluav taws kub hnyiab tshwm sim, ntau cov pa taws loj me me tau tawm, thiab lub tswb hluav taws xob hluav taws xob hluav taws xob yuav ceeb toom ua ntej tshaj lub tswb hluav taws xob ion. Hom chaw no txhawb kev teeb tsa ntawm photoelectric pa taws tswb. Yog tias koj xav muab cov txiaj ntsig ntawm ob qho tib si, koj tuaj yeem nruab ob hom kev ceeb toom pa taws hauv cheeb tsam uas xav tau kev ceeb toom pa taws.
