Tseem nyob hauv av telescopes tuaj yeem ntes tau tsuas yog qee qhov ntawm cov infrared spectrum vim feem ntau ntawm nws yog absorbed los ntawm cov dej vapor nyob rau hauv lub ntiaj teb cua. Vim li ntawd, infrared Cov cuab yeej ntes tau tuaj yeem "saib los ntawm" cov huab cua no kom pom lwm yam khoom pom tsis pom hauv thiab qab huab.
Tsis tas li ntawd, vim li cas cov kws tshawb fawb astronomers siv infrared telescopes?
Infrared astronomy muab cov kws tshawb fawb muaj peev xwm ntsuas qhov kub ntawm lub cev ntawm lub ntiaj teb, cov hnub qub, thiab cov plua plav hauv qhov chaw sib txuas. Nyob ntawd yog kuj muaj ntau molecules uas nqus infrared hluav taws xob muaj zog. Yog li txoj kev kawm ntawm cov muaj pes tsawg leeg ntawm astrophysical lub cev feem ntau ua tau zoo tshaj plaws nrog infrared telescopes.
Kuj Paub, lub hom phiaj ntawm Sofia yog dab tsi? SOFIA yog tsim los saib xyuas lub ntiaj teb infrared. Ntau yam khoom nyob rau hauv qhov chaw tawm yuav luag tag nrho lawv lub zog ntawm infrared wavelengths thiab feem ntau pom tsis pom thaum pom nrog lub teeb pom kev.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub koob yees duab infrared?
Ib infrared tsom iav raj yog a telescope uas siv infrared lub teeb kom pom lub cev ntuj ceeb tsheej. Infrared Lub teeb yog ib qho ntawm ntau hom hluav taws xob tam sim no hauv electromagnetic spectrum. Tag nrho cov khoom saum ntuj ceeb tsheej uas muaj qhov kub siab tshaj qhov xoom emit ib co qauv ntawm electromagnetic hluav taws xob.
Sofia NASA yog dab tsi?
Lub Stratospheric Observatory rau Infrared Astronomy ( SOFIA ) yog ib qho kev sib koom ua ke ntawm 80/20 NASA thiab German Aerospace Center (DLR) los tsim thiab tswj xyuas qhov chaw soj ntsuam huab cua.

Lub lens twg yog siv rau hauv tsom iav raj?
Hom telescope no hu ua refracting telescope.Feem ntau refracting telescopes siv ob lub ntsiab lo ntsiab muag. Qhov loj tshaj plaws yog hu ua lub hom phiaj lens, thiab lub lens me dua siv rau kev saib yog hu ua eyepiece lens
Nyob rau theem twg DNA nyuaj tshaj plaws kom pom nyob rau hauv lub tshuab tsom iav?
DNA yog qhov nyuaj tshaj plaws kom pom ntawm prophase theem ntawm mitosis. Kev piav qhia: Nyob rau theem prophase, tsis muaj cov chromosomes txhais tau zoo. DNA yog tam sim no nyob rau hauv daim ntawv ntawm nyias chromatin fibers uas nyuaj rau pom nyob rau hauv lub microscope
Nyob rau theem twg DNA nyuaj tshaj plaws pom nyob rau hauv lub tshuab tsom iav?
DNA yog qhov nyuaj tshaj plaws kom pom ntawm prophase theem ntawm mitosis. Kev piav qhia: Nyob rau theem prophase, tsis muaj cov chromosomes txhais tau zoo. DNA yog tam sim no nyob rau hauv daim ntawv ntawm nyias chromatin fibers uas nyuaj rau pom nyob rau hauv lub microscope
Cov qauv twg feem ntau yuav pom tau nrog lub tshuab ntsuas hluav taws xob tab sis tsis yog lub teeb tsom iav?
Hauv qab ntawm cov qauv tsim yog pom nyob rau hauv tib lub cell, nyob rau sab laug saib nrog lub teeb microscope, thiab nyob rau sab xis nrog cov kis tau tus mob electron microscope. Mitochondria pom tau nrog lub teeb pom kev zoo tab sis tsis tuaj yeem pom meej. Ribosomes tsuas yog pom nrog lub tshuab ntsuas hluav taws xob
Dab tsi yog cov lej thiab cov lej rational Yuav ua li cas cov ntsiab lus kos rau ntawm lub dav hlau sib koom tes?
Raws li peb tau hais, cov ntsiab lus ntawm lub dav hlau sib koom ua ke yog sawv cev raws li (a, b), qhov twg a thiab b yog tus lej lej. Rational cov lej yog cov lej uas tuaj yeem sau ua feem, p / q, qhov p thiab q yog tus lej. Peb hu rau x-coordinate ntawm lub point thiab peb hu b tus y-coordinate ntawm lub point
