Cov Robinson qhov project tsis yog azimuthal; tsis muaj qhov taw tes lossis cov ntsiab lus los ntawm txhua qhov kev qhia qhia kom raug . Cov Robinson qhov project yog qhov tshwj xeeb. Nws lub hom phiaj tseem ceeb yog los tsim kom pom kev txaus siab daim ntawv qhia ntawm tag nrho lub ntiaj teb no.
Kuj paub, hom phiaj xwm twg yog Robinson projection?
Cov Robinson qhov project yog a daim duab projection ntawm ib lub ntiaj teb daim ntawv qhia uas qhia tag nrho lub ntiaj teb ib zaug. Nws tau tsim tshwj xeeb hauv kev sim nrhiav kev sib haum xeeb zoo rau qhov teeb meem ntawm kev nthuav qhia tag nrho lub ntiaj teb raws li daim duab tiaj tus. Cov Robinson qhov project tau tsim los ntawm Arthur H.
Puas yog Robinson projection map qhia qhov loj ntawm cov teb chaws kom raug? Cov Robinson projection map yog oval-puab qhov projection . Cov duab thiab qhov loj ntawm lub teb chaws nyob ze ntawm txoj kab nruab nrab kom raug , tab sis cov cheeb tsam dej thiab cov av nyob ze ntawm tus ncej yog distorted kom phim cov duab ntawm lub daim ntawv qhia . Qhov no qhov projection tau tsim los ntawm American cartographer Arthur Robinson.
Ib yam li ntawd, qhov tsis zoo ntawm Robinson projection yog dab tsi?
Qhov zoo : Cov Robinson daim ntawv qhia qhov projection qhia tau hais tias feem ntau nyob deb, qhov ntau thiab tsawg thiab cov duab kom raug. Qhov tsis zoo : Cov Robinson daim ntawv qhia muaj ib co distortion nyob ib ncig ntawm tus ncej thiab ntug.
Daim duab qhia chaw twg yog qhov tseeb tshaj plaws?
AuthaGraph. Qhov no yog hands-down lub qhov tseeb tshaj plaws daim ntawv qhia projection nyob rau hauv muaj. Qhov tseeb, AuthaGraph Ntiaj Teb Daim ntawv qhia yog li proportionally zoo meej, nws magically folds nws mus rau hauv peb-dimensional ntiaj teb. Japanese kws kes duab vajtse Hajime Narukawa tau tsim qhov no qhov projection nyob rau hauv 1999 los ntawm sib npaug faib ib tug kheej kheej nto rau hauv 96 daim duab peb sab.

Puas yog nws muaj tseeb tias nyob rau hauv kev thauj mus los ntawm kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog?
Hauv kev thauj mus los passive, kev txav ntawm cov khoom hla ib daim nyias nyias yuav tsum muaj zog. _ Muaj tseeb_ 5. Endocytosis yog ib txoj kev uas ib lub cell membrane nyob ib puag ncig thiab siv cov khoom los ntawm ib puag ncig. Ib daim nyias nyias uas tso cai rau qee cov ntaub ntawv dhau los qhia txog kev xaiv permeability
Dab tsi yog qhov tsis zoo ntawm Robinson projection?
Robinson projections tsis sib npaug; lawv raug kev txom nyem los ntawm compression. Txawm li cas los xij, tus nqi ntawm cheeb tsam distortion feem ntau tsawg hauv li 45 ° ntawm kab zauv. Conformality: Lub Robinson projection tsis conformal; cov duab yog distorted ntau tshaj li lawv yuav nyob rau hauv ib tug tiag tiag conformal projection
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
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
