Hauv lej, a dav hlau yog ib lub tiaj, ob-seem nto uas txuas mus infinitely deb. A dav hlau yog ob-dimensional analogue ntawm ib tug point (zero dimensions), ib kab (ib dimension) thiab peb-dimensional qhov chaw.
Tsis tas li ntawd, lub dav hlau nyob rau hauv cov piv txwv geometry yog dab tsi?
A dav hlau extends infinitely nyob rau hauv ob qhov ntev. Ib piv txwv ntawm a dav hlau yog ib qho kev sib koom tes dav hlau . A dav hlau yog lub npe los ntawm peb lub ntsiab lus hauv dav hlau uas tsis nyob rau tib kab. Hauv qab no peb pom tus dav hlau ABC. Ib qhov chaw txuas mus tsis kawg nyob rau hauv tag nrho cov lus qhia thiab yog ib txheej ntawm tag nrho cov ntsiab lus nyob rau hauv peb qhov ntev.
Ib yam li ntawd, lwm lub npe rau lub dav hlau geometry yog dab tsi? Lwm yam npe rau dav hlau Ib yog dav hlau BCD thiab dav hlau CDE. b. Cov ntsiab lus C, E, thiab D nyob ntawm tib kab, yog li lawv yog collinear. Cov ntsiab lus B, C, E, thiab D yog tib yam dav hlau , yog li lawv yog coplanar.
Raws li, lub dav hlau geometry puas zoo ib yam li geometry?
Lub ntiaj teb nyob ib ncig ntawm peb yog pom tseeb peb-dimensional, muaj qhov dav, qhov tob thiab qhov siab, Khoom geometry cuam tshuam nrog cov khoom nyob rau hauv qhov chaw xws li lub cubes thiab spheres. Dav hlau geometry deals ntawm cov khoom uas tiaj tus, xws li daim duab peb sab thiab kab, uas tuaj yeem kos rau ntawm daim ntawv tiaj tus.
Koj txhais li cas lub dav hlau?
Hauv lej, a dav hlau yog ib lub tiaj, ob-seem nto uas txuas mus infinitely deb.
Cov dav hlau embedded nyob rau hauv peb-dimensional Euclidean qhov chaw
- Peb cov ntsiab lus tsis-collinear (cov ntsiab lus tsis nyob ntawm ib kab).
- Ib kab thiab taw tes tsis nyob ntawm kab ntawd.
- Ob txoj kab sib txawv tab sis sib tshuam.
- Ob kab sib luag.

Lub ntsiab lus dav dav rau RuBisCO yog dab tsi?
Ribulose-1,5-bisphosphate carboxylase/oxygenase, feem ntau paub los ntawm cov ntawv luv luv Rubisco, rubisco, RuBPCase, lossis RuBPco, yog ib qho enzyme koom nrog thawj kauj ruam tseem ceeb ntawm kev kho cov pa roj carbon monoxide, txheej txheem uas cov pa roj carbon dioxide hloov los ntawm cov nroj tsuag thiab lwm yam. Cov kab mob photosynthetic muaj zog nplua nuj
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Dab tsi yog cov lej thiab cov lej rational Yuav ua li cas cov ntsiab lus kos rau ntawm lub dav hlau sib koom tes?
Raws li peb tau hais, cov ntsiab lus ntawm lub dav hlau sib koom ua ke yog sawv cev raws li (a, b), qhov twg a thiab b yog tus lej lej. Rational cov lej yog cov lej uas tuaj yeem sau ua feem, p / q, qhov p thiab q yog tus lej. Peb hu rau x-coordinate ntawm lub point thiab peb hu b tus y-coordinate ntawm lub point
