Nrog kev nce qib ntawm kev siv thev naus laus zis, qhov kev thov rau cov khoom siv hluav taws xob tau nce zuj zus ib hnub. Thiab ib qho ntawm cov khoom tseem ceeb, cov hlau tsis muaj zog, ua lub luag haujlwm tseem ceeb. Resistance hlau yog ib feem siv los tswj cov tam sim no thiab voltage, feem ntau pom nyob rau hauv ntau yam khoom siv hluav taws xob. Kab lus no yuav qhia txog cov kev qhia tshwj xeeb ntawm cov xov hlau tsis muaj zog.

Resistance wire yog nyias hlau ua los ntawm cov ntaub ntawv tshwj xeeb uas tuaj yeem tsim cov yam ntxwv tsis kam. Nws feem ntau yog ua los ntawm cov hlau los yog alloys, xws li nickel chromium alloy, hlau chromium aluminium, thiab lwm yam.

Ua ntej, cia peb saib ntawm txoj kab uas hla ntawm cov hlau tsis kam. Txoj kab uas hla yog qhov ntev ntawm txoj kab hla ntu ntu ntawm cov hlau tsis kam, feem ntau ntsuas hauv millimeters (mm). Qhov loj ntawm txoj kab uas hla ncaj qha cuam tshuam cov conductivity ntawm cov hlau tsis kam. Feem ntau, lub thinner txoj kab uas hla, qhov ntau dua tus nqi kuj ntawm cov hlau tsis kam; Qhov tuab ntawm txoj kab uas hla, qhov me me ntawm qhov tsis kam ntawm cov hlau tsis kam. Yog li thaum xaiv cov hlau tsis muaj zog, nws yog ib qho tsim nyog los txiav txim siab txoj kab uas hla raws li cov kev cai tshwj xeeb hauv Circuit Court.

Thib ob, qhov ntev ntawm cov hlau tsis kam kuj tseem yog qhov tseem ceeb ntawm kev ntsuas. Qhov ntev txiav txim siab tag nrho qhov loj ntawm cov hlau tsis kam, feem ntau ntsuas hauv meters (m). Qhov loj ntawm qhov ntev yog feem ntau txiav txim siab los ntawm kev tsim hluav taws xob hauv Circuit Court, thiab xaiv qhov tsim nyog ntev raws li qhov yuav tsum tau muaj ntawm qhov tam sim no thiab qhov hluav taws xob tuaj yeem ua kom ruaj khov ntawm cov hlau tsis muaj zog.

Thaum kawg, tus nqi tsis kam ntawm cov hlau tsis kam yog qhov tseem ceeb parameter. Tus nqi kuj sawv cev rau qib ntawm qhov tsis kam ntawm cov hlau tsis kam mus rau qhov tam sim no, feem ntau ntsuas hauv ohms (Ω). Tus nqi kuj tuaj yeem ua tiav los ntawm kev kho cov khoom siv, txoj kab uas hla, thiab qhov ntev ntawm cov hlau tsis kam. Hauv kev siv tswv yim, peb tuaj yeem ua tau raws li cov kev cai sib txawv hauv Circuit Court los ntawm kev sib txuas cov hlau tsis muaj zog nrog cov nqi sib txawv.

Ntxiv rau peb lub ntsiab lus tshwj xeeb uas tau hais los saum no, kuj tseem muaj lwm yam cuam tshuam rau kev ua haujlwm ntawm cov hlau tsis kam. Piv txwv li, kev xaiv cov khoom muaj feem cuam tshuam rau kev ruaj ntseg thiab kev ua haujlwm ntawm cov xov hlau tsis zoo; Kev kho deg tuaj yeem txhim kho corrosion ntawm cov hlau tsis kam; Lub ambient kub kuj muaj kev cuam tshuam rau kev ua haujlwm ntawm cov hlau tsis muaj zog, thiab lwm yam.

Hauv cov ntsiab lus, kev xaiv ntawm cov kab hluav taws xob tiv thaiv yuav tsum muaj kev xav txog ntau yam. Raws li qhov yuav tsum tau ua hauv Circuit Court, txiav txim siab qhov tsim nyog txoj kab uas hla, qhov ntev, thiab tus nqi tsis kam, thaum ua tib zoo xaiv cov khoom siv thiab kev kho saum npoo, tuaj yeem ua kom lub cev ua haujlwm ntawm cov hlau tsis muaj zog hauv cov khoom siv hluav taws xob.

Nrog kev nce qib ntawm kev siv thev naus laus zis, qhov kev thov rau cov xov hlau tsis zoo hauv cov khoom siv hluav taws xob kuj tseem hloov mus tas li. Nyob rau hauv lub neej yav tom ntej, peb tuaj yeem pom tias cov xov hlau tsis sib haum yuav ua me me, ruaj khov, thiab ua haujlwm zoo dua. Txawm hais tias nws yog smartphones, khoos phis tawj, tsheb, lossis lwm yam khoom siv hluav taws xob tshiab, cov xov hlau tiv thaiv yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb, nqa kev yooj yim dua thiab kev zoo siab rau tib neeg.

Cov saum toj no yog ib qho kev taw qhia rau cov specifications thiab parameters ntawm kuj nyob ntawm tej. Kuv vam tias tsab xov xwm no tuaj yeem muab cov neeg nyeem nkag siab tob txog ntawm cov xov hlau tiv thaiv thiab muab kev taw qhia hauv kev siv tswv yim. Txawm hais tias cov xov hlau tiv thaiv me me, lawv ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob, txhawb kev txhim kho cov cuab yeej technology thiab kev vam meej ntawm tib neeg lub neej. Cia peb tos ntsoov los tsim kom muaj peev xwm ntau ntxiv rau kev txhim kho cov kab hluav taws xob tiv thaiv yav tom ntej!
