Edwin Hubble invented ib kev faib tawm ntawm cov galaxies thiab muab faib ua plaub pawg: spirals, barred spirals, ellipticals thiab irregulars. Nws cais spiral thiab barred kauv cov galaxies ntxiv raws li qhov loj ntawm lawv lub hauv paus bulge thiab kev ntxhib los mos ntawm lawv txhais tes.
Hauv qhov no, galaxies feem ntau faib li cas?
Galaxies tuaj yeem yog cais Raws li lawv cov duab: kauv, elliptical, lossis tsis xwm yeem. Edwin Hubble, uas yog Hubble Space Telescope yog npe, devised lwm nto moo kev faib tawm tswvyim rau cov galaxies . Hubble's system suav nrog elliptical thiab kauv cov galaxies tab sis tsis suav nrog irregulars.
Ib yam li ntawd, 4 hom galaxies yog dab tsi? Qhov kev faib tawm no yog hu ua Hubble Sequence. Nws faib cov galaxies rau hauv peb chav kawm loj nrog ob peb qhov kev hloov pauv. Niaj hnub no, galaxies tau muab faib ua plaub pawg: kauv, thaiv kauv , elliptical, thiab tsis xwm yeem.
Tsis tas li ntawd, dab tsi yog galaxies categorized los ntawm?
Galaxies yog cais Raws li lawv pom morphology li elliptical, kauv, los yog tsis xwm yeem. Ntau cov galaxies tau xav tias muaj cov qhov dub loj heev ntawm lawv qhov chaw.
Dab tsi yog cov yam ntxwv ntawm galaxies?
Galaxies yog cov kab ke ntawm cov plua plav, roj, cov teeb meem tsaus ntuj, thiab nyob qhov twg los ntawm ib lab mus rau trillion hnub qub uas tau tuav ua ke los ntawm lub ntiajteb txawj nqus. Yuav luag txhua qhov loj cov galaxies xav tias tseem muaj cov qhov dub loj heev ntawm lawv qhov chaw.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Dab tsi yog qhov txawv ntawm kauv galaxies thiab barred kauv galaxies?
Dab tsi yog qhov txawv ntawm ib lub galaxy barred kauv thiab lub elliptical galaxy? Ib qho kauv tsis pub muaj ob los yog ntau dua kauv caj npab nyob rau hauv ib lub tiaj tiaj, qhov twg caj npab txuas nrog ib lub hnub qub. Lub bar thiab kauv caj npab yog cov cheeb tsam ntawm lub hnub qub tsim. Qhov nruab nrab ntawm lub bar feem ntau yog ib tug kheej kheej bulge
Kev faib cov lej zoo li faib cov lej li cas?
Tsuas yog muab cov txiaj ntsig zoo thiab ua rau cov lus teb tsis zoo. Thaum koj faib ob tus lej nrog tib lub cim, qhov tshwm sim yeej ib txwm zoo. Tsuas yog faib qhov tseem ceeb thiab ua kom cov lus teb zoo. Thaum koj faib ob tus lej nrog cov cim sib txawv, qhov tshwm sim ib txwm tsis zoo
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Yuav ua li cas koj ntxiv rho tawm ntau thiab faib cov feem thiab cov zauv sib xyaw?
Cov zauv sib xyaw thiab cov zauv tsis zoo Muab cov zauv los ntawm tag nrho cov lej. Ntxiv cov khoom rau tus lej. Tus lej no yuav yog tus lej tshiab. Tus denominator ntawm qhov tsis tsim nyog feem yog tib yam li tus denominator nyob rau hauv thawj cov zauv sib xyaw
