Hluav taws yog tus tsiaj nyaum sib txawv hauv qhov chaw tshaj nws nyob hauv av. Thaum cov nplaim taws kub hnyiab hauv ntiaj teb, cov roj cua kub tau nce los ntawm qhov hluav taws , rub tawm cov pa oxygen hauv thiab thawb cov khoom combustion tawm. Hauv microgravity, cov pa roj kub tsis nce. Raws li cov tee dej kub hnyiab, ib lub nplaim kheej kheej engulfs nws, thiab cov koob yees duab sau tag nrho cov txheej txheem.
Khaws qhov no rau hauv kev xav, puas muaj hluav taws kub hauv qhov chaw?
Lwm txoj kev a hluav taws tuaj yeem nyob hauv qhov chaw yog los ntawm kev siv cov pa compressed. Hluav taws Txawm li cas los xij, feem ntau tsis tshwm sim hauv qhov chaw . Nws yog ib rooj plaub tshwj xeeb txawm hais tias yuav luag yeej yuav tsum tau txhob txwm ua los ntawm tib neeg. Cov hnub qub piv txwv tsis hlawv; lawv cov cua sov yog tshwm sim los ntawm nuclear fusion.
Qhov thib ob, ua li cas cov nplaim taws hlawv hauv qhov chaw? Hauv qhov chaw , hluav taws kub nyob rau hauv ib tug kheej vim lub ntiajteb txawj nqus tsis rub txias, denser gases cia rau lub hauv paus ntawm nplaim taws . Cov khoom hluav taws xob kuj tuaj yeem ua rau kub kub hauv microgravity - qee yam NASA tab tom tshawb nrhiav tam sim no rau nyob rau hauv kev cia siab ntawm kev txhim kho roj efficiency ntawm lub ntiaj teb.
Tsis tas li ntawd, hluav taws kub li cas hauv qhov chaw tsis muaj oxygen?
Hluav taws ua tsis tau hlawv tsis muaj ob yam tseem ceeb: roj (qhov khoom ntawd kub hnyiab ) thiab oxidizer (uas pib lub kub txheej txheem thiab ua kom nws mus). Yog li, koj xav tau hluav taws los txhawb koj lub foob pob hluav taws, tab sis koj tsis muaj txaus oxygen (ib qho oxidizer) hauv qhov chaw.
Koj puas tuaj yeem teeb lub teeb hauv qhov chaw?
Keeb Kwm teb: ua a sib dua ua haujlwm hauv xoom lub ntiajteb txawj nqus? Cov khoom sib tw, tswm ciab thiab qub-fashioned kua-roj-thiab-wick lub teeb Tsis ua hauj lwm zoo heev vim hais tias lawv cia siab rau convection los sib tov cov roj vapor thiab atmospheric oxygen, thiab convection cia siab rau lub ntiajteb txawj nqus.
