Cov proton - proton saw yog, zoo li kev lwj saw hlau , ib series cov tshuaj tiv thaiv . Cov khoom ntawm ib tshuaj tiv thaiv yog cov khoom pib ntawm cov tom ntej tshuaj tiv thaiv . Muaj ob yam ntawd chains ua los ntawm Hydrogen mus rau Helium nyob rau hauv lub hnub. Ib saw hlau muaj tsib cov tshuaj tiv thaiv , lwm saw hlau muaj rau.
Ib yam li ntawd, qhov txiaj ntsig ntawm cov saw proton proton yog dab tsi?
Cov net tau ntawm no saw hlau yog fusion ntawm plaub protons nyob rau hauv ib tug zoo tib yam helium nucleus (4Nws) nrog lub zog raug tso tawm rau lub hnub qub raws li Einstein qhov sib npaug. Cov khoom hu ua 'neutrinos' () raug tso tawm hauv cov txheej txheem fusion no.
Ib yam li ntawd, cov khoom lag luam ntawm cov proton proton saw yog dab tsi? Lub ntsiab ceg ntawm proton-proton saw.
- Ob qhov loj-1 isotopes ntawm hydrogen tau txais kev sib xyaw ua ke thiab beta lwj los tsim ib qho positron, neutrino, thiab ib qho loj-2 isotope ntawm hydrogen (deuterium).
- Lub deuterium reacts nrog lwm qhov loj-1 isotope ntawm hydrogen los tsim Helium-3 thiab gamma-ray.
Yog li ntawd, dab tsi yog tag nrho cov tshuaj tiv thaiv nuclear fusion nyob rau hauv lub hnub luv luv piav qhia txog proton proton saw?
Qhia luv luv txog cov proton – proton chain . Nrog peb Hnub , cov tag nrho cov tshuaj tiv thaiv fusion yog kev hloov ntawm Hydrogen rau Helium. Thawj txoj hauv kev rau qhov hloov dua siab tshiab no yog qhov proton - proton kev sib tham. Cov txheej txheem no pib nrog cov kev fusion ntawm ob Hydrogen nuclei rau hauv ib qho Deuterium nuclei.
Qhov twg cov proton proton saw tshwm sim?
Cov txheej txheem hu ua Proton - Proton (PP) Cov saw , thiab nws ua haujlwm nyob rau hauv lub hnub thiab hnub qub uas zoo sib xws.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Yuav ua li cas tshwm sim nyob rau hauv ib tug nuclear fusion tshuaj tiv thaiv?
Hauv nuclear fusion, koj tau txais lub zog thaum ob lub atoms koom ua ke los ua ib qho. Hauv fusion reactor, hydrogen atoms tuaj ua ke los tsim helium atoms, neutrons thiab ntau lub zog. Nws yog tib hom tshuaj tiv thaiv uas powers hydrogen foob pob thiab lub hnub. Muaj ntau ntau hom fusion tshuaj tiv thaiv
Yuav ua li cas lub zog transformation tshwm sim nyob rau hauv ib tug nuclear fais fab nroj tsuag?
Nuclear fais fab nroj tsuag ua haujlwm li cas? Peb qhov kev sib koom ua ke ntawm cov ntaub ntawv hluav taws xob tshwm sim ntawm cov chaw tsim hluav taws xob nuclear: nuclear zog hloov mus rau hauv thermal zog, thermal zog hloov mus rau txhua yam zog, thiab txhua yam zog hloov mus rau hluav taws xob
Yuav ua li cas tshwm sim thaum ib tug tam sim no nqa coil muab tso rau hauv ib tug magnetic teb?
Yog tias tus neeg nqa khoom nqa tam sim no tau muab tso rau hauv qhov chaw sib nqus, nws ntsib lub zog Lorentz (tshwj tsis yog lub kaum sab xis ntawm qhov ntws ntawm tam sim no thiab cov kab hlau nplaum yog 0 °)
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
