Thaum twg yog qhov loj dub tawm?
Ua li cas? Ntau tshaj 50 lab tus tib neeg hauv Ontario thiab sab qaum teb sab hnub tuaj Tebchaws Meskas tau ntsib qhov hluav taws xob loj tshaj plaws hauv keeb kwm ntawm North America rau Lub Yim Hli 14, 2003.
Dab tsi ua rau dub tawm xyoo 2003?
Lub Yim Hli 14, 2003, series ntawm kev ua txhaum los ntawm cov ceg ntoo kov cov kab hluav taws xob hauv Ohio, uas tau nyuaj los ntawm tib neeg yuam kev, teeb meem software, thiab khoom siv tsis ua haujlwm, ua rau muaj kev kub ntxhov thoob plaws hauv North American keeb kwm.

Puas yog cov hluav taws xob muaj hluav taws xob zoo?
Ntau yam tseem ceeb, lossis subatomic, cov khoom ntawm cov khoom muaj cov khoom siv hluav taws xob. Piv txwv li, electrons muaj tus nqi tsis zoothiab protons muaj tus nqi zoo, tab sis neutrons muaj pes tsawg tus nqi. Yuav ua li cas them electrons e nqa?
Puas yog hluav taws xob hluav taws xob muaj ob qhov xwm txheej?
EM hluav taws xob yog lub npe vim nws muaj hluav taws xob thiab sib nqus teb uas ib txhij oscillate hauv cov dav hlau sib koom ua ke rau ib leeg thiab rau kev taw qhia ntawm kev nthuav tawm los ntawm qhov chaw. ✓ Electromagnetic tawg muaj ob qhov xwm txheej:
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
Puas yog lub tshuab hluav taws xob puas muaj lub tshuab hluav taws xob?
Vim li cas lub tshuab hluav taws xob sab hauv combustion yuav tsum tsis muaj lub tshuab hluav taws xob los ua kom cov roj tsis zoo li roj av? Spark plugs yog siv nyob rau hauv cov roj cav mus ignite cov pa roj sib tov whereas nyob rau hauv diesel engines lub xub ntiag ntawm lub txim plugs yog tsis tsim nyog.
