Radius ntawm curvature yog cov lub vojvoog ntawm lub voj voog uas kov qhov nkhaus ntawm ib qho taw tes thiab muaj qhov sib npaug thiab curvature ntawm qhov ntawd. Radius yog qhov deb nruab nrab qhov chaw thiab lwm qhov taw tes ntawm lub voj voog ntawm lub voj voog lossis qhov chaw ntawm tus kheej. Hauv cov voj voog koj yuav tsum siv lub sij hawm lub vojvoog.
Ib yam li ntawd, lub voj voog ntawm curvature hauv Lens yog dab tsi?
Radius ntawm curvature (ROC) muaj lub ntsiab lus tshwj xeeb thiab kos npe rau hauv kev tsim kho qhov muag. Ib tug kheej kheej lens ormirror nto muaj qhov chaw ntawm curvature nyob ib leeg lossis decentered los ntawm qhov system hauv zos optical axis. Thedistance los ntawm vertex mus rau qhov chaw ntawm curvature yog cov radius ntawm curvature ntawm qhov chaw.
Ib yam li ntawd, lub vojvoog ntawm curvature equation yog dab tsi? Cov radius ntawm curvature ntawm qhov nkhaus ntawm pointM(x, y) yog hu ua inverse of the curvature K ntawm nkhaus taw tes no: R = 1K. Li no rau dav hlau curves muab los ntawm qhov tseeb kev sib npaug y = f(x), cov radius ntawm curvature ntawm pointM(x,y) yog muab los ntawm cov lus hauv qab no: R = [1+(y'(x))2]32.
Ua li no, qhov txawv ntawm radii thiab radius yog dab tsi?
“ Radii "yog qhov yooj yim tshaj plaws ntawm" lub vojvoog ” Qhov ntawd yog, yog tias koj tab tom tham txog ntau dua ib qho, koj yuav hais tias " radii .” Hauv ib kab lus, koj yuav hais tias "ob radii ua ib txoj kab uas hla. " Qhov no tsuas yog tib yam li "axis" thiab "axes," nrog "axes" ua ntau hom ntawm "axis."
Yuav ua li cas ntsuas curvature ntawm lub lens?
Tus nqi uas tuaj yeem ua tau ntsuas nrog lub vojvoog ntawm curvature ntawm lens aperture ntau yog nyob ntawm tus qauv interferometer lens f / tus lej thiab lens ntawm R / tus lej (lub vojvoog ntawm curvature muab faib los ntawm qhov tseeb aperture ntawm lub spherical nto piv ntawm lawv).

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
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
