Cov txheej txheem triple-alpha yog ib txheej ntawm cov tshuaj tiv thaiv nuclear fusion uas peb helium -4 nuclei (alpha hais) hloov mus rau hauv carbon.
Xav txog qhov no, ua li cas helium nuclei fuse tsim carbon nuclei?
Thaum qhov kub ntawm lub hnub qub nce mus txog 100 lab degrees, peb sib tsoo helium nuclei ua tau fuse ua a carbon nucleus . Cov txheej txheem no tseem hu ua triple alpha txheej txheem. Helium Kev kub hnyiab tshwm sim tom qab lub hnub qub tau hloov zuj zus tawm ntawm Lub Ntsiab Cai, thaum nws yog liab loj.
Tsis tas li ntawd, helium fuse rau hauv dab tsi? Lawv fuse helium mus txog rau thaum cov tub ntxhais yog cov pa roj carbon ntau thiab oxygen. Tom qab helium yog sab hauv lub hauv paus ntawm lub hnub qub, nws yuav txuas mus rau hauv lub plhaub ib ncig ntawm cov pa roj carbon-oxygen core. Nyob rau hauv txhua rooj plaub, helium yog ua fused mus rau carbon ntawm cov txheej txheem triple-alpha. Qhov no ua tau Tom qab ntawd tsim cov pa oxygen, neon, thiab cov ntsiab lus hnyav dua ntawm cov txheej txheem alpha.
Kuj paub, ua li cas helium fuse rau carbon?
Helium , ua ib tug loj nuclei tshaj hydrogen, yuav tsum tau ntau zog kinetic rau fuse , uas txhais tau tias kub dua. Ntawm 100 lab degrees, helium tuaj yeem hloov mus rau carbon los ntawm cov txheej txheem triple-α. Lub zog tso tawm los ntawm cov txheej txheem triple-α txuas ntxiv kom sov cov tub ntxhais nce nws qhov kub thiab txias ntau dua.
Dab tsi nuclei fuse tsim oxygen?
Ob lub helium nuclei fuse tsim a nucleus ntawm Dab tsi nuclei fuse tsim Oxygen ? Tseeb lossis cuav: Hnub qub yog qhov loj ntawm lub hnub thiab tuaj yeem tsim cov ntsiab lus hnyav dua Oxygen.

Yuav ua li cas helium nuclei fuse tsim carbon nuclei?
Ntawm qhov kub thiab txias txaus txaus, 3-lub cev cov tshuaj tiv thaiv hu ua triple alpha txheej txheem tuaj yeem tshwm sim: Ob lub helium nuclei ('alpha particles') fuse tsim tsis ruaj khov beryllium. Yog tias lwm lub helium nucleus tuaj yeem fuse nrog beryllium nucleus ua ntej nws lwj, cov pa roj carbon ruaj khov yog tsim nrog rau gamma rays
