Fission yog qhov sib cais ntawm qhov hnyav, tsis ruaj khov rau hauv ob lub zog sib zog, thiab fusion yog txheej txheem uas ob lub teeb nuclei ua ke ua ke tso tawm ntau lub zog. Txawm li cas los xij, ob qhov txheej txheem muaj lub luag haujlwm tseem ceeb hauv yav dhau los, tam sim no thiab yav tom ntej ntawm kev tsim hluav taws xob.
Yuav ua li cas muaj zog fission lossis fusion?
Fusion tsuas yog tsim lub zog ntau dua li nws siv hauv cov nuclei me me (hauv cov hnub qub, Hydrogen & nws cov isotopes fuse rau hauv Helium). … Lub zog ntawm ib qho kev tshwm sim ntau dua (hauv cov piv txwv no) hauv fission, tab sis lub zog ib nucleon (fusion=txog 7 MeV / nucleon, fission=txog 1 Mev / nucleon) ntau dua hauv fusion.
Dab tsi yog qhov txawv ntawm fission thiab fusion piv txwv?
Nyob rau hauv fission, lub zog yog tau txais los ntawm kev sib cais hnyav atoms, piv txwv li uranium, rau hauv me me atoms xws li iodine, caesium, strontium, xenon thiab barium, rau npe tsuas yog ib tug atoms. ob peb. Txawm li cas los xij, fusion yog sib txuas lub teeb atoms, piv txwv li ob hydrogen isotopes, deuterium thiab tritium, los tsim cov helium hnyav dua.
Qhov twg muaj kev nyab xeeb dua fission lossis fusion?
Nyob rau xyoo 2019, National Geographic tau piav qhia nuclear fusion ua "dawb huv grail rau yav tom ntej ntawm nuclear fais fab." Tsis tsuas yog nws yuav tsim lub zog ntau dua kev nyab xeeb, nws tseem yuav tsim cov khoom siv hluav taws xob tsis zoo dua li qhov fission, los ntawm cov khoom siv riam phom-qib hauv siv roj rods.siv tsheej lab xyoo kom lwj…
Vim li cas fission phem dua fusion?
Yog tsis muaj cov electrons, atoms muaj qhov zoo thiab tawm tsam. Qhov no txhais tau hais tias koj yuav tsum muaj lub zog atomic siab heev kom tau txais cov khoom no kom muaj kev sib txuas lus nuclear. High zog particles yog qhov teeb meem. Qhov no yog vim li cas fusion nyuaj thiab fission kuj yooj yim (tab sis tseem ua tau nyuaj).
