Cov khoom siv hluav taws xob tshwj xeeb qhia lub peev xwm ntawm cov khoom siv hluav taws xob, tus nqi no yog qhov sib npaug ntawm cov hluav taws xob tiv thaiv.
Thaum nws los txog rau tus nqi tshwj xeeb, nws txhais tau tias nrhiav qhov ntsuas ntawm qhov ntsuas rau chav tsev ntawm tus yam ntxwv. Cia peb pib nrog cov piv txwv yooj yooj yim, uas yuav pab koj nkag siab lub ntsiab lus ntawm qhov tshwm sim sai sai.
Kev nqus tshwj xeeb yog qhov yooj yim tshaj plaws uas qhia qhov loj ntawm ib lub cubic meter ntawm cov khoom nyob rau hauv ib txwm muaj. Hauv qhov no, qhov ntsuas ntawm qhov ntsuas yog kilogram, thiab chav tsev ntawm cov khoom yog cubic meter.
Cov xwm txheej rau kev ntsuas ntsuas raws li ib txwm muaj yog qhia kom meej, txij li nrog kev nce siab, hais lus nruj me ntsis, ib lub cubic meter ntawm cov khoom yuav muaj qhov hnyav dua li ntawm qhov qub. Saib ua ntej, peb nco ntsoov tias semiconductors, piv txwv li, tuaj yeem hloov lawv cov hluav taws xob tsis zoo hauv txoj kev pom zoo thaumhloov kub los yog lub teeb.
Tam sim no rov qab rau lo lus nug ntawm dab tsi yog hluav taws xob conductivity. Raws li tau hais los saum toj no, tus nqi no yog qhov sib txuam ntawm kev tiv thaiv, uas nyob rau hauv lem tau txhais raws li hauv qab no:
Resistivity yog qhov tsis kam ntawm ib lub voos xwmfab nrog ib sab ntawm 1 meter rau hluav taws xob tam sim no, muab tias tam sim no ntws nruj nreem rau ib qho ntawm lub ntsej muag ntawm lub voos xwmfab. Kev coj tus kheej tuaj yeem txhais tau zoo ib yam, tab sis nws tsim nyog ntxiv tias cov kev cai rau kev ntsuas raws li ib txwm muaj kuj tseem ceeb heev rau rooj plaub no.
Tam sim no, kev tshawb fawb ntseeg tias hluav taws xob conductivity yog ncaj qha proportional rau lub square ntawm tus nqi ntawm cov khoom uas ua rau tam sim no, lawv tus naj npawb ntawm cov teeb meem ib ntim, thiab inversely proportional rau kev mus los ntawm tus nqi nqa khoom. Hauv kev nkag siab qhov kev txhais lus no yog qhov kev piav qhia ntawm vim li cas Ohm txoj cai tsis siv rau cov pa roj. Ntawm ib qho nqi ntawm lub zog hluav taws xob hluav taws xob, cov txheej txheem ionization tshwm sim, thiab tam sim no loj hlob zoo li avalanche. Uas yog siv nyob rau hauv vuam los yog nyob rau hauv elementary fluorescent teeb.
Raws li kev daws teeb meem, qhov xwm txheej nthuav dav dua yog tias koj mus ze lawv ntawm cov haujlwm no. Cov hluav taws xob conductivity ntawm cov kev daws teeb meem feem ntau yog nyob ntawm tus naj npawb ntawm cov cab kuj, uas yog dawb ions raug them tsis zoo lossis zoo. Vim tsis muaj cov ions zoo li no hauv cov dej distilled,ces qhov tshwj xeeb hluav taws xob conductivity ntawm dej yog ze rau xoom. Qhov no txhais tau hais tias tam sim no los ntawm cov dej huv yuav tsis mus. Cov txheej txheem los ntsuas cov dej ntxhia lossis dej paug, tshwj xeeb tshaj yog ph, yog raws li qhov tshwm sim no.
Tshwj xeeb hluav taws xob conductivity yog lub sijhawm txiav txim siab uas yuam kev siv cov hlau muaj txiaj ntsig hauv hluav taws xob. Vim tias qhov muaj txiaj ntsig zoo ntawm qhov ntsuas no, cov hlau tsis zoo dhau los ua ib qho tseem ceeb ntawm kev ntsuas qhov tseeb tshaj plaws. Tsawg tus neeg paub tias qhov kev xav ntawm cov hlau kuj tseem nyob ntawm nws qhov kev tiv thaiv, uas yog vim li cas iav feem ntau ua los ntawm cov nyiaj.
