Ob leeg fusion thiab fusion yog nuclear cov tshuaj tiv thaiv uas tsim zog , tab sis cov ntawv thov tsis zoo ib yam. Fission yog qhov tawg ntawm ib qho hnyav, tsis ruaj khov nucleus rau hauv ob lub sib zog nuclei, thiab kev fusion yog tus txheej txheem uas ob lub teeb nuclei ua ke ua ke tso tawm ntau ntawm zog.

Kuj nug, qhov twg muaj zog dua nuclear fission lossis fusion?

Fission tsuas yog tsim ntau lub zog ntau dua li nws siv hauv cov nuclei loj (cov piv txwv feem ntau yog Uranium & Plutonium, uas muaj nyob ib ncig ntawm 240 nucleons (nucleon = proton lossis neutron)). fusion tsuas yog tsim ntau lub zog tshaj nws siv hauv cov nuclei me me (hauv cov hnub qub, Hydrogen & nws cov isotopes fusing rau hauv Helium).

Tsis tas li ntawd, puas yog Chernobyl fission lossis fusion? Lwm qhov laj thawj rau kev tso tawm cov khoom siv hluav taws xob yog qhov Chernobyl reactor ua haujlwm txawv dua li lwm cov chaw tsim hluav taws xob. Yuav luag txhua cov nroj tsuag ua haujlwm ntawm lub hauv paus ntsiab lus hu ua "tus kheej-sustaining nuclear fission chain reaction," qhov twg neutrons bombard los yog ntaus atoms nyob rau hauv cov roj, ua rau fission.

Hauv qhov no, qhov twg yog qhov txaus ntshai nuclear fission lossis fusion?

Nuclear fission tsim txoj kev ntau radioactive tshuaj tshaj nuclear fusion . Hauv Nuclear fission , hnyav nucleus faib ua ob qhov tsis ruaj khov thiab cov khoom tsis ruaj khov no tau dhau los ua ntau lub xov tooj cua tawg kom ruaj khov, thaum nyob hauv nuclear fusion me me nuclei ua ke los ua ib qho hnyav nucl

Puas muaj kev sib xyaw ua ke txias?

Tam sim no tsis muaj tus qauv theoretical lees txais uas yuav tso cai txias fusion tshwm sim. Xyoo 1989, ob tus kws tshaj lij electrochemists, Martin Fleischmann thiab Stanley Pons, tau tshaj tawm tias lawv cov cuab yeej tau tsim cov cua sov tsis zoo ("cov cua kub ntau") ntawm qhov loj heev uas lawv tau lees tias yuav cuam tshuam cov lus piav qhia tshwj tsis yog hais txog cov txheej txheem nuclear.
