Thaum xaiv tus pas ntsuas kub, muaj ob peb yam los txiav txim siab
Nws yog qhov tseem ceeb los xaiv tus pas ntsuas kub yog rau cov kev sojntsuam thiab cov khoom siv kuaj sim thaum ntsuas kub. Cov hauv qab no yuav tsum tau txiav txim siab: qhov tseeb. Ntau cov hluav taws xob ntawm cov ntsuas kub ua rau PPM, Ohm, thiab / lossis cov txuj ci kub kub. Qhov hloov dua siab tshiab los ntawm ohms lossis ppm rau qhov kub thiab txias yog nyob ntawm tus pas ntsuas kub siv. Rau kev sojntsuam nrog 1 {{0 {2}}}}}}}}}}}}}}}}}. 1ppm yog sib npaug rau 0.1m ω lossis 0.25m. Nws tseem tsim nyog yuav tau them sai sai rau seb cov ntsuas ntsuas yog "nyeem" lossis "ntau yam".
Kev Ntsuas Yuam Kev
Thaum ua kev ntsuas siab, nws yog ib qho tseem ceeb kom paub meej tias tus pas ntsuas kub tuaj yeem tshem tawm cov kev sib txuas thermoelectric sib txawv ntawm cov kev ntsuas sib txawv. Ib qho txheej txheem rau tshem tawm thermoelectric yuam kev yog siv hloov hom DC lossis tsawg zaus AC tam sim no.
teeb meem
Ceev faj nrog qhov ntsuas no. Qee qhov chaw tsim hluav taws xob kub tsis meej thiab qhov raug. Ib qho kev daws teeb meem ntawm {{{{{0}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} ib lub thawv ruaj khov lossis kuaj xyuas qhov ruaj khov ntawm kev ntsuas hluav taws xob.
Txoj kev
Feem ntau cov ntsuas kub cov neeg tsim hluav taws xob muab cov ntsuas kev ntsuas cov txheej txheem ntawm qhov kub (feem ntau 0 degree c). Qhov no yog qhov tseem ceeb heev, tab sis koj feem ntau yuav tsum tau ntsuas qhov dav dav, yog li nws yog qhov tseem ceeb heev kom nkag siab qhov tseeb ntawm tus pas ntsuas kub hauv nws cov haujlwm. Yog tias cov ntsuas cua sov ntawm tus pas ntsuas kub yog qhov zoo heev, tom qab ntawd nws qhov tseeb index yuav zoo ib yam thoob plaws feem ntau ntau qhov ntau. Txawm li cas los xij, txhua qhov ntsuas hluav taws xob muaj qee qhov kev ua tsis tau ntawm qhov tsis yog txoj cai thiab tsis kiag li tawm. Thov xyuas kom cov chaw tsim tshuaj paus muab cov txuj ci ua haujlwm ua kom muaj raws li qhov ua tiav ntawm kev ua haujlwm, lossis muab cov qauv kab lus uas koj siv thaum xam pom kev tsis paub tseeb.
