Vim li cas daim iav convex siv los ua daim iav saib tom qab?
Convex mirrors feem ntau yog siv los ua rear-saib (tis) iav hauv tsheb vim hais tias lawv muab ib qho erect, virtual, tag nrho cov duab ploj zuj zus ntawm cov khoom nyob deb nrog kev pom dav dua. Yog li, daim iav convex ua rau tus neeg tsav tsheb pom thaj tsam loj dua li qhov yuav ua tau nrog daim iav dav hlau
Dab tsi yog cov xim muaj nyob rau hauv daim ntawv qhia kev phom sij rau kev noj qab haus huv hauv NFPA 704?
NFPA 704 pob zeb diamond kos npe siv los tso saib cov ntaub ntawv no muaj plaub ntu xim: xiav, liab, daj, thiab dawb. Txhua ntu yog siv los txheeb xyuas ib pawg sib txawv ntawm qhov muaj peev xwm txaus ntshai. Ntu xiav ntawm NFPA xim code cim qhia txog kev phom sij rau kev noj qab haus huv
Koj yuav siv daim duab qhia chaw twg rau qhov kev ua ub no?
Cov duab qhia chaw no yog siv rau ntau daim ntawv thov, los ntawm kev mus pw hav zoov, yos hav zoov, nuv ntses, thiab hiking mus rau kev npaj hauv nroog, kev tswj cov peev txheej, thiab kev soj ntsuam. Cov yam ntxwv tshwj xeeb tshaj plaws ntawm daim ntawv qhia saum toj kawg nkaus yog qhov peb-dimensional zoo ntawm lub ntiaj teb saum npoo yog ua qauv los ntawm kev siv cov kab contour
Kev noj zaub mov zoo li cas yog siv los txhim kho kev noj qab haus huv?
Khoom noj khoom haus genomics muab cov txhais tau tias los tsim cov molecular biomarkers thaum ntxov, piv txwv li kev hloov pauv ntawm kev saib xyuas kev noj qab haus huv thiab kev loj hlob ntawm tus kab mob. Cov noob no tej zaum yuav raug siv los ua lub hom phiaj los txheeb xyuas cov khoom noj khoom haus uas muaj peev xwm hloov kho lawv cov kev qhia
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
