Lub tshuab hluav taws xob tswj cov xaim nyob thiab siv tus cwj mem xeem los ntsuas cov hlau nruab nrab. Vim li cas thiaj muaj lub teeb me ntsis?
Ua ntej tshaj plaws, nws yuav tsum paub meej tias txawm hais tias cov xov hlau nyob (lub ntsiab lus yog cov xaim theem) raug txiav los yog tsis, cov xaim nruab nrab yuav tsis raug them raws li qhov xwm txheej ib txwm muaj. Yog hais tias cov kab nruab nrab nyob, nws txhais tau hais tias muaj teeb meem nyob qhov twg ntawm kab. Yog li yuav ua li cas thiaj paub qhov teeb meem nyob qhov twg? Rau cov neeg siv hluav taws xob zoo tib yam, cia peb qhia qhov yooj yim thiab siv tau nrawm nrawm thiab ua cov txheej txheem:
1. Hais txog qhov kev piav qhia ntawm qhov teeb meem no, vim hais tias cov kab nruab nrab yog me ntsis ci, qhov ua rau ntawm qhov tshwm sim no feem ntau yog oxidation ntawm qhov sib tshooj ntawm cov kab nruab nrab, ua rau kev sib cuag tsis zoo. Txawm li cas los xij, qhov xwm txheej no tuaj yeem txiav txim siab raws li kev cuam tshuam ntawm txoj kab nruab nrab ntawm txoj kab tseem ceeb. , vim hais tias cov kab nruab nrab ntawm txoj kab tseem ceeb raug txiav los yog muaj kev sib cuag tsis zoo, qhov tshwm sim txhaum thiab qhov tshwm sim txawv, thiab yuav tsis raug tshuaj xyuas ntawm no.
2. Tshawb nrhiav hauv ntu thiab nqaim qhov dav. Ua ntej, xyuas seb cov kab nruab nrab ntawm lub taub hau sab sauv thiab sab qis ntawm qhov hloov pauv yog qhov qub thaum lub ntsiab hloov pauv nyob rau hauv txoj haujlwm kaw. Yog tias cov kab nruab nrab yog qhov qub thiab tsis muaj lub zog, nws feem ntau yog ib qho teeb meem nyob rau sab nraub qaum ntawm qhov hloov. Koj tuaj yeem tshawb xyuas cov pob qij txha ntawm kab kab los ntawm ntu. Tom qab nrhiav tau qhov txhaum, tsuas yog rewire thiab qhwv nws. Vim tias qhov teeb meem feem ntau yog nyob ntawm txoj kab txuas. Qhov xwm txheej no tshwm sim feem ntau nrog cov kab hluav taws xob qub los ntawm lub sijhawm ntev dhau los. Niaj hnub no, kev sib txuas hauv tsev thiab kev teeb tsa yog kev tshawb fawb heev, thiab qhov teeb meem no feem ntau tsis tshwm sim.
3. Yog tias thaum kuaj xyuas qhov hloov pauv kom muab cov pawg nce thiab nqis, tsis muaj lub zog nyob rau hauv nruab nrab kab ntawm lub taub hau pawg sab sauv, tab sis muaj hwj chim nyob rau hauv lub taub hau pawg. Hauv qhov no, qhov hloov pauv feem ntau yog tawg. Koj tuaj yeem tig qhov hloov mus rau thiab tawm ob peb zaug, thiab qee zaum lub zog tuaj yeem rov qab tau ib ntus, tab sis koj tseem yuav tsum hloov qhov hloov tam sim ntawd.
Thaum lub sijhawm tshuaj xyuas, yog tias cov kab nruab nrab ntawm lub taub hau ntawm qhov hloov pauv tseem nyob, qhov no, feem ntau koj tuaj yeem tsuas yog hu rau kev kho, vim tias tej zaum yuav muaj kev tshuaj xyuas tus ncej, thiab cov neeg siv tsis tuaj yeem daws tau yooj yim.
Muaj ob txoj hauv kev. Ua ntej, txhawm rau tso cai rau cov neeg siv kom pom qhov hloov pauv tau yooj yim hauv qhov tsaus ntuj, qee qhov hloov pauv phab ntsa muaj qhov taw qhia lub teeb txuas nrog hla tus hloov. Thaum lub qhov hluav taws xob kaw lawm, qhov taw qhia lub teeb tseem nyob. Ib qho me me tam sim no dhau los ntawm kev hloov. Qhov thib ob, txhua lub teeb fluorescent, txawm tias nws yog lub teeb fluorescent zoo tib yam lossis lub teeb txuag hluav taws xob, muaj qee qhov kev ncua sij hawm tua cov yam ntxwv ntawm nws cov phosphor, uas yog hu ua "afterglow". Niaj hnub no, science tau nce qib. Nrog LCD saib thiab cov khoom siv sib xws, tej yam uas tsis tshwm sim tib lub sijhawm tuaj yeem pom tau yooj yim ntawm tib lub vijtsam. Piv txwv li, lub ntsuas hluav taws xob electrocardiogram qhia txog kab kab rov tav uas hloov pauv nce thiab nqis nrog lub plawv dhia. Qhov tseeb, txhua qhov kev hloov pauv ntawm kab kab rov tav no tsis tshwm sim tib lub sijhawm, tab sis muaj cov txheej txheem sijhawm. Yav dhau los, thaum tsuas muaj CRT saib, tsuas yog ib qho taw qhia hloov pauv nrog lub plawv dhia. Yuav kom tso saib ib kab, yuav tsum tau siv "ntev tom qab" saib, kom lub scanning point yuav tsis tawm tam sim ntawd tom qab dhau los, tab sis yuav rov tshwm sim tom qab lub sij hawm ntev. Maj mam extinguishing nws yuav tig lub zog ntawm ib tug taw tes rau hauv cov zaub ntawm ib kab. Lub oscilloscopes nyob rau lub sijhawm ntawd kuj ua haujlwm ntawm tib txoj cai.
Cov kab nruab nrab yog lub voj voog ntawm txhua yam khoom siv hluav taws xob. Txij li cov kab nruab nrab muaj qee qhov kev tiv thaiv, qhov ntau dua qhov kev tawm tsam ntawm cov kab nruab nrab lossis qhov loj dua qhov tam sim no ntawm cov kab nruab nrab, qhov siab dua qhov sib thooj voltage saum nws. Yog li ntawd, cov kab nruab nrab tsis muaj qhov tsis muaj hluav taws xob txhua, thiab nws muaj peev xwm ua tau tias tus cwj mem ntsuas tau ci me ntsis. Tau kawg, yog tias muaj kev sib cuag tsis zoo nyob rau hauv nruab nrab Circuit Court, thiab lwm yam, qhov nruab nrab voltage yuav siab. Yog li nws yog qhov zoo tshaj plaws los siv lub voltmeter los ntsuas qhov voltage.
Yog tias lub fuse ntawm ib theem ntawm lub transformer tawg, nws tseem yuav ua rau cov kab nruab nrab teeb me ntsis thaum ntsuas nrog lub cwj mem hluav taws xob. Thaum lub cev muaj zog raug hlawv tawm thiab ib theem ntawm txoj kab nyob deb dhau los ntawm lub cev muaj zog thiab hauv av, nws tseem yuav ua rau cov kab nruab nrab teeb me ntsis thaum ntsuas nrog tus cwj mem hluav taws xob. Thaum cov kab nruab nrab raug txiav tawm thiab lub zog dhau los ntawm cov khoom siv hluav taws xob, nws tseem yuav pom tias cov kab nruab nrab raug them thiab tus cwj mem hluav taws xob yuav ci dua.
Nws yooj yim heev. Raws li ntev raws li qhov nruab nrab Circuit Court txuas zoo, qhov tshwm sim no tsis zoo li tshwm sim. Yog tias qhov tshwm sim no tshwm sim, yuav tsum muaj kev sib txuas lossis kev ua haujlwm tsis zoo nyob rau hauv qhov chaw nruab nrab, lossis cov khoom siv hluav taws xob tuaj yeem txuas nrog hauv series. Txoj kev daws teeb meem yog txhawm rau txuas cov kev sib txuas tsis zoo los yog ua tsis zoo ntawm qhov nruab nrab Circuit Court. Yog tias ob lub tshuab hluav taws xob txuas nrog lub voj voog, txiav tawm ib qho khoom siv hluav taws xob thiab khaws ib qho khoom siv hluav taws xob nkaus xwb.
