Microwave qhov cub yog cov khoom siv hauv tsev tseem ceeb. Peb tau hnov tias hlau tsis tuaj yeem muab tso rau hauv microwave qhov cub. Dab tsi yuav tshwm sim?
Lub hauv paus ntsiab lus ntawm microwave cua sov yog yooj yim: thaum microwaves radiate rau zaub mov, yeej ib txwm muaj ib tug npaum li cas ntawm cov dej nyob rau hauv cov zaub mov, thiab dej yog tsim los ntawm polar molecules (qhov zoo thiab tsis zoo nqi chaw ntawm molecules, txawm thaum lub sab nraud hluav taws xob teb. tsis muaj). coincident), txoj kev taw qhia ntawm qhov polar molecule yuav hloov nrog lub microwave teb. Vim qhov no txav ntawm polar molecules ntawm cov dej hauv cov zaub mov.
Thiab kev sib cuam tshuam ntawm cov molecules uas nyob ib sab ua rau muaj qhov tshwm sim zoo ib yam li kev sib txhuam, uas ua rau cov dej kub nce, yog li qhov kub ntawm cov khoom noj kuj nce. Cov zaub mov rhuab los ntawm microwaves yog rhuab nyob rau hauv tib lub sij hawm, kom tag nrho cov khoom yog rhuab tusyees thiab kub nce sai. Ntawm qhov zaus ntawm 2.45 billion zaug ib ob, nws nkag mus 5cm tob rau hauv cov zaub mov kom sov thiab ua kom lub zog ntawm cov molecules.
