Hydrogen atoms tawm ntawm 1420 MHz (ib lub wavelength ntawm 21 cm). Hydroxyl molecules, tsim los ntawm ib lub atom ntawm hydrogen thiab ib lub atom ntawm oxygen (OH), tawm ntawm plaub lub xov tooj cua tshwj xeeb xws li 1612. MHz mus 1720 MHz.
Hauv qhov no, dab tsi raws nraim 21 cm kab ntawm hydrogen kab?
Cov hydrogen nyob rau hauv peb galaxy tau mapped los ntawm kev soj ntsuam ntawm 21 - cm wavelength kab ntawm hydrogen gas. Ntawm 1420 MHz, qhov hluav taws xob no los ntawm hydrogen nkag mus rau hauv huab huab huab thiab muab peb daim ntawv qhia ua tiav ntau dua hydrogen dua li cov hnub qub lawv tus kheej vim lawv pom lub teeb yuav tsis nkag mus rau hauv cov huab cua.
Ib tug kuj nug, vim li cas hydrogen tsuas emit 4 xim? Txawm tias hydrogen muaj nkaus xwb ib qho hluav taws xob, nws muaj ntau qib zog. Thaum nws cov electron dhia los ntawm qib zog siab dua mus rau qis dua, nws tso tawm photon. Cov photons zoo li kab. Rau vim li no, ho hydrogen muaj nkaus xwb ib tug electron, ntau tshaj ib tso pa tawm kab yog pom nyob rau hauv nws spectrum.
Raws li txoj cai, vim li cas hydrogen emit lub teeb ntsuab xiav?
Ntxiv zog xws li hluav taws xob ua rau lub hydrogen atoms rau resonate thiab tawm raws li lawv oscillation ceev thiab muab tawm electromagnetic hluav taws xob (photons) ua rau thos Hydrogen emit dab tsi yog pom los ntawm qhov muag raws li ib tug lub teeb xiav thaum nyob rau hauv lub iav raj thiab hluav taws xob yog khiav ntawm nws.
Koj puas tuaj yeem muaj qhov tsis zoo?
Yog li lub tswv yim ntawm a tsis zoo zaus , thaum peb tham txog rotating vectors, ua rau kev nkag siab zoo. Yog tias peb tig mus rau qhov zoo, zoo li qhov no, koj tuaj yeem hais tias yog qhov zoo zaus . Thiab yog hais tias peb nyob nraum rotating nyob rau hauv lub tsis zoo txoj kev, zoo li no, koj tuaj yeem hais tias yog ib tsis zoo zaus.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov sib txawv ntawm qhov txheeb ze zaus thiab qhov xwm txheej txheeb ze?
Marginal txheeb ze zaus yog qhov piv ntawm cov lej ntawm qhov sib koom ua ke txheeb ze zaus hauv kab lossis kab thiab tag nrho cov ntaub ntawv muaj nuj nqis. Conditional txheeb ze zaus tus lej yog qhov sib piv ntawm qhov sib koom sib txheeb zaus thiab muaj feem cuam tshuam txog qhov sib txawv ntawm qhov sib txawv
