Lub npe refractor yog muab los ntawm lub sij hawm refraction, uas yog qhov khoov ntawm lub teeb thaum nws dhau los ntawm ib qho nruab nrab mus rau lwm qhov sib txawv ntawm qhov sib txawv - piv txwv li, los ntawm huab cua mus rau iav. Lub iav yog hu ua lub lens thiab tej zaum yuav muaj ib lossis ntau yam khoom.
Ib yam li ntawd, lub hom phiaj ntawm lub tsom iav raj refracting yog dab tsi?
Lub refracting telescope (tseem hu ua lub refractor) yog ib hom optical telescope uas siv lub lens raws li nws Lub hom phiaj tsim ib daim duab (tseem hu ua dioptric telescope). Lub refracting telescope tsim yog Ameslikas siv nyob rau hauv neeg soj xyuas tsom iav thiab astronomical telescopes tab sis kuj yog siv rau ntev tsom xam lub koob yees duab lo ntsiab muag.
Tsis tas li ntawd, yuav ua li cas thiaj ua tau lub lens refracting? Ib qho yooj yim refracting tsom iav raj muaj ob lo ntsiab muag, Lub Hom Phiaj thiab lub qhov muag. Yeej, lub hom phiaj lens tsim cov duab ntawm ib qho khoom nyob deb ntawm nws qhov kev ua kom pom tseeb thiab lub ntsej muag lub ntsej muag ua kom pom cov duab no.
Ib tug kuj yuav nug, yog vim li cas refracting telescopes ntev?
Ib txoj hauv kev siv ntau lub lo ntsiab muag them nyiaj los tiv thaiv chromatic aberration. Lwm txoj kev siv ib tug heev ntev lub hom phiaj focal ntev (qhov deb ntawm qhov tsom thiab lub hom phiaj) kom txo tau cov nyhuv. Qhov no yog vim li cas thaum ntxov refracting telescopes tau ua heev ntev.
Nyob qhov twg refracting telescopes nyob?
Yerkes Observatory, hauv Williams Bay, Wisconsin, muaj tsev loj tshaj plaws refracting tsom iav raj puas tau tsim rau kev tshawb fawb astronomical, nrog lub lens loj uas yog 40 ntiv tes (1.02 meters) inch.

Vim li cas nws thiaj hu ua Krebs cycle?
Yog vim li cas Nws yog ib lub voj voog Nws yog ib lub voj voog vim oxaloacetic acid (oxaloacetate) yog lub caij nyoog molecule uas yuav tsum tau txais ib qho acetyl-CoA molecule thiab pib dua lwm lub voj voog
Vim li cas nws thiaj li hu ua deoxyribonucleic acid?
Deoxyribonucleic acid (DNA) yog ib qho loj molecule uas muaj nucleotides (phosphate + qab zib + lub hauv paus) qhov twg cov suab thaj yog ' nruab nrab' ntawm nucleotide. Lub 'deoxyribo' hauv lub npe yog muab los ntawm cov piam thaj ntawm DNA. Phosphates thiab qab zib tsim tawm sab nraud ntawm cov molecule thaum lub hauv paus ua rau lub hauv paus
Dab tsi yog thaj chaw ntawm pej xeem kev hloov pauv thiab vim li cas nws thiaj li muaj txiaj ntsig thaum kawm txog pej xeem?
Population dynamics yog ceg ntawm lub neej sciences uas kawm txog qhov loj thiab hnub nyoog muaj pes tsawg leeg ntawm cov pejxeem raws li dynamical systems, thiab cov txheej txheem lom thiab ib puag ncig tsav lawv (xws li yug thiab tuag tus nqi, thiab los ntawm kev nkag teb chaws thiab emigration)
Dab tsi yog reflecting thiab refracting telescope?
Reflecting Telescopes vs. Refracting Telescopes. Lub tsom iav raj refracting (refractor) siv lo ntsiab muag los sib sau ua ke thiab tsom teeb, thaum lub tsom iav tsom iav (reflector) siv daim iav. Lub refractor telescope sau ntau lub teeb rau hauv lub lens dua li tuaj yeem sib sau nrog qhov muag liab qab
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
