Dej hnyav yog tsim los ntawm Ontario Hydro's dej hnyav cog 'B' ntawm Bruce Power Development hauv Tiverton, Ontario. Cov dej hnyav tsis yog tsim, tab sis theej nws yog muab rho tawm los ntawm qhov ntau uas pom nyob rau hauv lub pas dej dej.
Kuj paub yog, dej hnyav puas tshwm sim lawm?
Cov dej hnyav tshwm sim ib txwm muaj , txawm li cas los xij nyob rau hauv ntau me me dua li niaj zaus dej . Kwv yees li, ib qho dej molecule rau txhua nees nkaum lab dej molecules yog dej hnyav . Vim tias deuterium yog ib qho isotope ruaj khov, dej hnyav tsis yog radioactive.
Tsis tas li ntawd, nws puas muaj kev nyab xeeb rau haus dej hnyav? Ua los ntawm swapping cov dej hydrogen atoms nrog lawv cov txheeb ze hnyav dua, deuterium, dej hnyav zoo thiab saj zoo li niaj zaus dej thiab hauv me me (tsis pub ntau tshaj tsib tablespoons rau tib neeg) yog nyab xeeb haus.
Tib neeg kuj nug tias, koj ua li cas dej hnyav?
Dej hnyav tuaj yeem ua tau siv hydrogen sulfide- dej chemical pauv, dej distillation, los yog electrolysis. Hydrogen sulfide- Dej Txauv - Hauv kev sib xyaw ntawm hydrogen sulfide (H2S) thiab dej Nyob rau hauv chemical equilibrium, lub concentration ntawm deuterium nyob rau hauv dej yog ntau dua qhov concentration hauv H2S.
Cov dej hnyav yog dab tsi?
Dej hnyav . Dej hnyav (D2O), tseem hu ua deuterium oxide, dej muaj li ntawm deuterium, hydrogen isotope nrog ib tug loj ob npaug ntawm hydrogen zoo tib yam, thiab oxygen.

Puas yog qhov hnyav lossis qhov hnyav?
Qhov loj ntawm ib yam khoom yog ib qho kev ntsuas ntawm cov khoom inertial khoom, los yog tus nqi ntawm cov khoom nws muaj. Qhov hnyav ntawm ib yam khoom yog ib qho kev ntsuas ntawm lub zog ntawm qhov khoom los ntawm lub ntiajteb txawj nqus, lossis lub zog xav tau los txhawb nws. Qhov rub ntawm lub ntiajteb txawj nqus ntawm lub ntiaj teb muab ib yam khoom ib tug downward acceleration ntawm txog 9.8 m / s2
Cov ntsiab lus hnyav dua hlau tuaj qhov twg?
Ntau lub ntsiab lus hnyav dua hlau yog tsim supernova tawg. Tus nqi ntawm lub zog tso tawm thaum lub sij hawm supernova tawg yog siab heev uas lub zog pub dawb thiab cov neutrons dawb streaming los ntawm cov tub ntxhais sib tsoo ua rau muaj kev cuam tshuam loj heev, ntev dhau los ntawm kev tsim cov hlau
Qhov txawv ntawm qhov hnyav thiab qhov hnyav yog dab tsi?
Raws li lub npe qhov sib txawv ntawm qhov hnyav thiab hnyav yog tias lub nra yog lub nra; qhov hnyav yuav tsum tau nqa thaum qhov hnyav yog lub zog ntawm ib qho khoom vim qhov kev sib tw ntawm nws thiab lub ntiaj teb (lossis yam khoom siv astronomical nws feem ntau cuam tshuam los ntawm)
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Cov ntsiab lus hnyav tuaj qhov twg los?
Tag nrho cov ntsiab lus hnyav dua cov hlau lead yog tsim los ntawm tawg r-txheej txheem nucleosynthesis nyob rau hauv supernova explosions, colliding neutron hnub qub thiab lwm yam. Qhov sib cais ntawm r-txheej txheem thiab s-txheej txheem ntau lawm ntawm hnyav dua hlau (peak) hais txog 50:50
