Bimetallic sawb taw qhia
Ib qho bimetal yog ib qho dej ntawm ob lossis ntau dua hlau los yog lwm yam ntaub ntawv uas muaj cov khoom tsim. Bimetals tseem hu ua kub bimetals. Vim tias qhov txawv thermal expansion coefficients ntawm txhua tus txheej txheem, thaum hloov qhov kub, qhov deformation ntawm cov txheej txheem yog ntau tshaj qhov deformation ntawm passive txheej, kom tag nrho cov bimetal yog bent mus rau sab ntawm lub passive txheej. Tom qab ntawd, lub curvature ntawm cov ntaub ntawv nkag hloov ua rau deformation.
