Ua cas cov mov es thiaj paub tias cov mov twb siav lawm?
Ua cas lub mov tsis paub tias nws twb siav lawm?
1. Qhov tseeb, lub tshuab ua mov tsis "paub" seb cov mov puas tau siav. Tom qab dhia mus rau lub xeev sov, cov mov tseem tsis tau siav, peb tseem yuav tsum tau ua kom sov lub sijhawm ntawm peb tus kheej. Lub tshuab ua mov siv lub hauv paus ntsiab lus ntawm qhov kub siab tshaj ntawm cov dej hauv qab lub siab. Tsuav cov dej tuaj yeem convect ib txwm, qhov kub hauv qab ntawm lub lauj kaub yuav tsis tshaj 100 degrees.
2. Thaum cov nplej ntws tawm ntawm cov dej, hauv qab ntawm lub lauj kaub pib cua sov tshaj 100 degree, NdFeB cov hlau nplaum tas mus li poob nws cov hlau nplaum, thiab qhov kev hloov pauv nkag mus rau hauv lub xeev txuag hluav taws xob. Yog tias koj ua kua zaub, lub mov cooker yuav tsis hloov mus rau lub xeev ua haujlwm kom txog thaum cov kua zaub boiled qhuav.
Vim li cas cov hlau nplaum poob nws cov hlau nplaum?
Rau cov ntaub ntawv ferromagnetic, siab tshaj qhov ntsuas kub, qhov thermal co ntawm atoms yog qhov hnyav dhau thiab cuam tshuam rau lub sijhawm sib nqus qub, thiab cov khoom yuav hloov ntawm ferromagnet mus rau paramagnet. Cov tshuab ua mov hauv tsev siv qhov kub-kub degaussing txoj cai ntawm ferromagnets. Thaum cov nplej nyob rau hauv lub lauj kaub yog rhuab mus rau ib ncig ntawm 103 degree, cov hlau nplaum ntawm ferromagnetic khoom nyob rau hauv lub mov cooker decays sharply ntawm qhov kub thiab txias, thiab lub attraction ntawm NdFeB mus tas li hlau nplaum tom qab demagnetization yog heev txo. Yog li, lub tshuab hluav taws xob hloov hluav taws xob tau txiav tawm, tso cai rau lub tshuab ua mov kom nkag mus rau hauv lub xeev khaws cia kom sov, kom cov mov tuaj yeem siav yam tsis muaj kuab lom.
