Yuav ua li cas yog qhov zero kab yog me ntsis ci thaum lub qhov hloov pauv tswj cov hlau nyob nrog mem hluav?
Ua ntej tshaj plaws, nws yuav tsum paub meej tias txoj kab xoom yuav tsis raug them raws li qhov xwm txheej ib txwm muaj, tsis hais seb txoj kab nyob (lub ntsiab lus thev naus laus zis yog theem kab) raug txiav los yog tsis. Yog tias cov kab nruab nrab raug them, nws txhais tau hais tias muaj teeb meem ntawm qhov chaw ntawm kab, yog li peb tuaj yeem paub qhov teeb meem nyob qhov twg? Rau cov neeg siv khoom siv hluav taws xob zoo tib yam, qhia qhov yooj yim thiab siv tau nrawm tshawb nrhiav thiab tuav txoj hauv kev:
Ua ntej, piav qhia txog qhov teeb meem no, yog vim li cas rau qhov tshwm sim no yog qhov xoom kab yog me ntsis ci, uas feem ntau tshwm sim los ntawm oxidation ntawm xoom kab lap sib koom ua ke, ua rau kev sib cuag tsis zoo. Txawm li cas los xij, qhov xwm txheej no tuaj yeem txiav txim siab raws li qhov kev cuam tshuam ntawm xoom kab ntawm txoj kab tseem ceeb, vim tias qhov tshwm sim txhaum cai thiab qhov tshwm sim tshwm sim los ntawm kev cuam tshuam los yog kev sib cuag tsis zoo ntawm xoom kab ntawm kab tseem ceeb sib txawv, yog li kuv yuav tsis txheeb xyuas nws. ntawm no.
Thib ob, ntu kev tshawb nrhiav thiab nqaim lub peev xwm. Ua ntej, xyuas seb qhov xoom kab 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 txoj kab xoom yog qhov qub thiab tsis muaj hluav taws xob, feem ntau yog ib qho teeb meem nyob rau tom kawg ntawm qhov hloov. Koj tuaj yeem tshawb xyuas qhov sib koom ua ke ntawm kab ntu los ntawm ntu, thiab nrhiav qhov yuam kev thiab tom qab ntawd rov ua dua. Vim tias qhov teeb meem feem ntau yog nyob ntawm txoj kab txuas. Cov xwm txheej zoo li no tshwm sim feem ntau, uas feem ntau yog cov kab hluav taws xob qub ntev dhau los. Tam sim no cov kab hluav taws xob sab hauv tsev thiab kev teeb tsa yog kev tshawb fawb heev, yog li cov teeb meem zoo li no yuav tsis tshwm sim feem ntau.
3. Yog tias tsis muaj hluav taws xob ntawm xoom kab ntawm lub taub hau ntawm pawg sab sauv thiab hluav taws xob ntawm lub hauv paus pawg hauv qab lub taub hau thaum lub qhov hloov tau kuaj xyuas, qhov xwm txheej no feem ntau yog qhov hloov pauv, thiab qhov hloov pauv tuaj yeem qhib thiab kaw ob peb zaug, thiab qee zaum cov hluav taws xob tuaj yeem rov qab tau ib ntus, tab sis qhov hloov pauv yuav tsum tau hloov raws sijhawm.
Thaum kuaj xyuas, yog tias xoom kab ntawm pawg lub taub hau ntawm qhov hloov pauv tseem raug them, qhov xwm txheej no tsuas yog kho tau los ntawm kev hu xov tooj, vim tias tej zaum yuav muaj kev tshuaj xyuas tus ncej, uas tus neeg siv tsis tuaj yeem daws tau yooj yim.
Muaj ob txoj hauv kev. Ua ntej, qee qhov hloov pauv phab ntsa muaj qhov taw qhia lub teeb txuas nrog rau qhov hloov mus kom cov neeg siv pom qhov hloov pauv tau zoo nyob hauv qhov tsaus ntuj. Thaum lub qhov hluav taws xob tawm, qhov taw qhia lub teeb tseem muaj me me tam sim no dhau los ntawm qhov hloov. Qhov thib ob, txhua lub teeb fluorescent, txawm tias cov raj fluorescent zoo tib yam lossis lub teeb txuag hluav taws xob, muaj qee yam kev ncua sij hawm tua, uas yog hu ua "afterglow". Tam sim no nrog kev kawm ntawm kev tshawb fawb, nrog LCD thiab cov khoom siv sib xws, tej yam uas tsis tshwm sim nyob rau tib lub sijhawm tuaj yeem pom tau yooj yim hauv tib daim duab, xws li ECG saib, uas qhia tau hais tias kab kab rov tav uas hloov pauv thiab nqis nrog cov lub plawv dhia, tab sis qhov tseeb tag nrho cov kev hloov pauv ntawm kab kab rov tav no tsis yog yam tshwm sim tib lub sijhawm, tab sis yog lub sijhawm txheej txheem. Yav dhau los, thaum tsuas muaj CRT zaub, tsuas yog ib qho taw qhia hloov pauv nrog lub plawv dhia. Txhawm rau ua kom pom ib kab, peb yuav tsum xaiv "ntev tom qab" tso saib, kom lub scanning point tsis tawm tam sim ntawd tom qab dhau, tab sis maj mam tawm mus tom qab lub sijhawm ntev, uas ua rau lub zog ntawm qhov taw tes dhau los ua kab. tso saib. Thiab oscilloscope lub sijhawm ntawd yog tib txoj cai.
Cov kab nruab nrab yog lub voj ntawm txhua yam khoom siv hluav taws xob. Vim hais tias cov kab nruab nrab muaj ib qho kev tiv thaiv, qhov ntau dua qhov kev tiv thaiv los yog tam sim no ntawm cov kab nruab nrab, qhov siab dua qhov sib txuam voltage. Yog li ntawd, nws muaj peev xwm hais tias lub xoom kab tsis yog tag nrho voltage-dawb, thiab mem hluav yog me ntsis ci. Tau kawg, yog tias qhov nruab nrab Circuit Court muaj kev sib cuag tsis zoo, nws yuav ua rau qhov nruab nrab voltage siab. Yog li nws yog qhov zoo tshaj los ntsuas qhov voltage nrog lub voltmeter.
Qhov qhib Circuit Court ntawm ib theem fuse ntawm transformer kuj yuav ua rau xoom kab yuav dimly lit los ntawm hluav taws xob cwj mem. Thaum lub cev muaj zog kub hnyiab tawm thiab ib theem yog grounded los ntawm lub cev muaj zog, nws tseem yuav ua rau xoom kab yuav dimly lit los ntawm hluav taws xob cwj mem. Thaum txoj kab xoom raug txiav tawm ntawm lub hwj chim, lub xoom kab yuav raug ntsuas los ntawm cov khoom siv hluav taws xob. Cov cwj mem hluav taws xob yog ci dua.
Yooj yim yooj yim, tsuav yog qhov nruab nrab Circuit Court ua tau zoo, qhov tshwm sim no tsis yooj yim sua. Yog tias qhov no tshwm sim, yuav tsum muaj kev sib txuas lossis kev ua haujlwm tsis zoo nyob rau hauv qhov chaw xoom kab lossis kev sib txuas nrog cov khoom siv hluav taws xob. Txoj kev daws teeb meem yog los txuas cov kev sib txuas tsis zoo los yog ua haujlwm tsis zoo ntawm qhov nruab nrab Circuit Court ruaj khov. Yog tias ob qho khoom siv hluav taws xob txuas nrog hauv ib lub voj voog hauv ib qho, ib qho khoom siv hluav taws xob yuav raug tshem tawm thiab tsuas yog ib qho khoom siv hluav taws xob tuaj yeem khaws cia.
