Hais Txog Kev Coj
Kev Xeeb: Kev coj ua ntawm cov dej yog feem ntau yog siv los qhia qhov tseeb ntawm dej. Yog hais tias tus conductivity siab heev, nws txhais tau hais tias cov ntsiab lus ntawm cov khoom noj conductive hauv cov dej muaj ntau, thiab qhov dej huv ntawm dej tsawg heev. Yog tias qhov kev coj ua yog tsawg heev, nws qhia tias cov zaub mov uas tuaj yeem raug ionized hauv dej. Tsis tshua muaj, qhov tseeb ntawm cov dej kuj siab dua. Piv txwv li, qhov conductivity ntawm siab-purity dej yog EC = 0.1.0us / cm; lub conductivity ntawm cov dej haus ib txwm muaj 1 ~ 10 peb / c.

Dab tsi yog dej conductivity thiab resistivity
Resistivity Cov conductivity ntawm dej yog cuam tshuam nrog tus nqi tsis kam ntawm dej. Tus nqi loj tsis kam, conductivity tsis zoo, tus nqi qis tsis kam, thiab kev coj zoo. Raws li Ohm txoj cai lij choj, nyob rau qhov ntsuas kub, qhov ntsuas tus nqi R ntawm dej yog qhov sib xyaw ua ke mus rau qhov chaw hla ntawm qhov dav ntawm F ntawm qhov hluav taws xob thiab sib npaug mus rau qhov deb L ntawm qhov hluav taws xob: R = ρ & # 183; L / F qhov twg ρ yog Resistivity, lossis kev tawm tsam tshwj xeeb. Chav ntsuas ntawm kev tawm tsam yog ohm (ohm, code Ω), lossis microohm (μΩ), chav thoob ntiaj teb (SI) ntsuas ntawm 1Ω sib npaug nrog 106μΩ tiv thaiv kev ua lag luam yog ohm (Ω & # 183; M). Yog tias qhov chaw hla ntu F ntawm qhov electrode tau ua 1CM2, tom qab ntawd tus nqi thev tawm yog sib npaug nrog cov thev thev naus laus zis. Lub peev txheej tiv thaiv dej yog cuam tshuam nrog cov ntsev nyob hauv dej, qhov ion ion nyob rau hauv dej, them cov ions, thiab qhov ceev ntawm ions. Yog li no, qhov dej ntshiab hluav taws xob muaj qhov loj heev, thiab lub tshuab nqus dej ntshiab ultra ntshiab tseem muaj ntau dua. Lub purer dej, qhov ntau dua lub resistivity. Kev Coj Tus Cwj Pwm Vim muaj ntau cov dej qab ntsev nyob hauv dej, nws muaj nyob rau hauv daim ntawv ntawm ions. Thaum muab ob khub hluav taws xob tso rau hauv dej, tom qab ua kom muaj zog, cov ions raug them yuav txav mus rau ib qho kev coj ua nyob rau hauv qhov kev ua ntawm qhov hluav taws xob. Cov degree ntawm lub zog ntawm dej hluav taws xob conductivity hu ua conductivity S (los yog kev coj ua). Kev siv hluav taws xob ua kom pom tseeb cov ntsev nyob hauv dej thiab yog qhov taw qhia tseem ceeb ntawm kev coj huv ntawm cov dej. Cov dej ntxuav hauv qhov dej, qhov ntsev tsawg dua, qhov ntau dua qhov kev tawm tsam thiab qhov cuam tshuam me me. Ultrapure dej tuaj yeem ua hluav taws xob tsis zoo. Qhov loj ntawm kev coj yog sib npaug rau qhov rov ua tsis kam, piv txwv li: S = 1 / R
