Kev siv hluav taws xob nyhuv
Qhov cuam tshuam ntawm cov nyhuv thermoelectric, lub dielectric nrog cov nyhuv electrothermal (feem ntau electret) hu ua electrothermal lub cev. Thaum cov polarization mus tas li ntawm lub cev hluav taws xob lub cev tau hloov pauv los ntawm txoj kev ntawm hluav taws xob sab nraud nyob rau hauv cov xwm txheej adiabatic, nws qhov kub yuav hloov. Qhov no hu ua cov nyhuv hauv hluav taws xob. Adiabatic depolarization tuaj yeem txo qis dua qhov kub thiab txias, thiab tuaj yeem siv kom tau ultra-low kub zoo ib yam li cov qauv adiabatic demagnetization (saib cov nyhuv magnetocaloric). Cov khoom siv hluav taws xob cua sov tshwj xeeb suav nrog strontium titanate ceramics thiab polyvinylidene fluoride (PVF) electrets.
