Lus Nug: Cov kab lus no yuav tshawb txog cov kev hloov pauv hauv kev tiv thaiv thaum cov hlau tsis kam ua thinner. Los ntawm kev txheeb xyuas qhov kev sib raug zoo ntawm cov hlau tsis muaj zog thiab tam sim no thiab qhov hluav taws xob, peb yuav piav qhia seb qhov thinning ntawm cov hlau tsis kam ua rau muaj qhov nce lossis txo qhov tsis kam, thiab tshawb xyuas nws daim ntawv thov hauv cov xwm txheej sib txawv.

kev taw qhia:

Hauv peb lub neej niaj hnub, kev tawm tsam yog lub tswv yim tseem ceeb ntawm lub cev. Txawm li cas los xij, ntau tus neeg tseem muaj qee qhov tsis ntseeg txog qhov laj thawj ntawm kev hloov pauv ntawm kev tawm tsam. Ib qho ntawm cov lus nug yog, puas yuav nce lossis txo qis thaum cov hlau tsis kam ua thinner? Kab lus no yuav nkag siab tob rau hauv qhov teeb meem no thiab pab cov neeg nyeem daws lawv qhov tsis meej pem.

1. Kev sib raug zoo ntawm cov hlau tsis kam, tam sim no, thiab kev ua haujlwm

Ua ntej, peb yuav tsum nkag siab txog kev sib raug zoo ntawm cov xaim hluav taws xob, tam sim no, thiab qhov tsis kam. Raws li Ohm txoj cai, tam sim no (I) yog proportional to resistance (R) thiab inversely proportional to voltage (V). Qhov ntawd yog, I = V / R. Hauv cov qauv no, qhov tsis kam (R) yog qhov tseem ceeb ntawm cov hlau tsis kam.

2. Thinning ntawm cov hlau tsis kam: ua rau nce lossis txo qhov tsis kam?

Tom ntej no, peb yuav tham txog qhov kev hloov pauv ntawm kev tiv thaiv thaum cov hlau tsis kam ua thinner. Thaum cov hlau tsis kam ua thinner, nws qhov chaw hla ntu txo qis. Raws li kev sib raug zoo ntawm qhov tsis kam thiab qhov chaw hla ntawm cov hlau tsis kam (R = ρ L / A, qhov twg ρ yog qhov resistivity, L yog qhov ntev, thiab A yog qhov chaw hla ntu), peb tuaj yeem pom tias a Kev txo qis hauv cheeb tsam hla ntu yuav ua rau muaj kev tiv thaiv ntxiv.

3. Cov ntaub ntawv ntawm thinning kuj nyob ntawm tej daim ntawv thov teb

Txawm hais tias nws yog qhov tseeb hais tias qhov thinning ntawm cov hlau tsis muaj zog ua rau muaj kev tiv thaiv ntau ntxiv, hauv kev siv tswv yim, peb tuaj yeem pom tias tseem muaj cov xwm txheej uas qhov thinning ntawm cov hlau tsis kam ua rau txo qis hauv kev ua haujlwm. Piv txwv li, nyob rau hauv ib co high-precision kuj pab kiag li lawm, los ntawm kev tswj qhov luaj li cas ntawm cov hlau tsis kam, zoo tuning ntawm tus nqi kuj yuav ua tau tiav, yog li txhim kho qhov tseeb ntawm lub Circuit Court.

Tsis tas li ntawd, nyob rau hauv cov thermistor, qhov thinning ntawm cov hlau tsis kam kuj tuaj yeem ua rau txo qhov tsis kam. Lub thermistor yog ib qho khoom siv uas siv qhov kub thiab txias hloov pauv tus nqi tsis kam. Thaum qhov kub nce siab, cov khoom ntawm cov hlau tsis kam yuav nthuav dav, ua rau cov hlau tsis kam ua kom nyias nyias, yog li ua rau txo qis hauv kev ua haujlwm. Cov yam ntxwv no yog siv dav hauv kev ntsuas kub thiab tswj.

4. Cov lus xaus

Los ntawm kev txheeb xyuas ntawm kev sib raug zoo ntawm cov hlau tsis kam thiab tam sim no thiab qhov hluav taws xob, peb tuaj yeem txiav txim siab tias thinning cov hlau tsis kam yuav ua rau muaj kev tiv thaiv ntau ntxiv. Txawm li cas los xij, hauv qee qhov kev thov tshwj xeeb, qhov thinning ntawm cov hlau tsis kam kuj tuaj yeem ua rau txo qis, uas feem ntau yog nyob ntawm cov khoom siv thiab cov ntawv thov.

Cov ntsiab lus:

Tsab ntawv no delves rau hauv qhov teeb meem ntawm kev hloov pauv los ntawm qhov thinning ntawm cov hlau tsis kam. Nyob rau hauv txoj kev xav, ib tug thinner kuj hlau yuav ua rau ib tug nce nyob rau hauv tsis kam; Txawm li cas los xij, hauv kev siv tswv yim, kuj muaj cov xwm txheej uas ua rau txo qis hauv kev tawm tsam. Peb tau hais txog qee qhov xwm txheej hauv daim ntawv thov, ua kom pom qhov sib txawv thiab yooj yim ntawm cov xov hlau tsis muaj zog. Los ntawm tsab xov xwm no, cov neeg nyeem tuaj yeem nkag siab ntau dua ntawm qhov cuam tshuam ntawm thinning resistance xov hlau, nrog rau lawv cov xwm txheej thiab cov yam ntxwv hauv kev siv tswv yim.
