Thermo emf nce mus rau qhov siab tshaj plaws ntawm qhov kub thiab txias (θ ) hu ua nruab nrab kub thiab maj mam txo thiab nws thiaj li ua zero ntawm qhov kub (θ1) hu ua inversion temperature. Tshaj li qhov kub ntawm inversion, Thermo emf hloov kos npe thiab tom qab ntawd nce.
Thermoelectric emf txawv li cas nrog qhov ntsuas kub?
Thermo emf nce nrog nce hauv qhov kub kom txog thaum nws ncav cuag qhov siab tshaj plaws. Qhov kub ntawm qhov kub sib txuas ntawm qhov kev taw qhia ntawm thermo emf thim rov qab, hu ua qhov kub ntawm inversion. Peltier effect yog cov nyhuv thim rov qab.
Qhov kub ntawm qhov kev hloov pauv nyob ntawm dab tsi?
Qhov kub ntawm kev hloov pauv yog nyob ntawm cov khoom siv thiab qhov kub ntawm ob qhov sib txuas. Yog tias qhov ntsuas kub ntawm qhov sib txuas txias tau qis dua qhov nruab nrab kub tseem nyob ruaj khov ntawm qhov kub thiab txias tab sis tus nqi ntawm qhov kub ntawm inversion ntawm lub thermocouple nce.
Tus qauv ntawm qhov ntsuas kub inversion yog dab tsi?
Yog li qhov kev hloov pauv hloov pauv yog qhov ntsuas kub tseem ceeb uas cov roj kub yuav nce lossis txo. Joule Thompson nthuav dav yog txheej txheem adiabatic. dH=∆U + PdV, U yog lub zog sab hauv, P yog siab thiab V yog ntim.
thermo emf yog dab tsi?
The Seebeck cov nyhuv yog lub zog hluav taws xob (emf)uas txhim kho hla ob lub ntsiab lus ntawm cov khoom siv hluav taws xob thaum muaj qhov sib txawv ntawm qhov kub ntawm lawv. Lub emf hu ua Seebeck emf (los yog thermo/thermal/thermoelectric emf).
