symmetry, hauv biology, kev rov ua dua ntawm cov khoom hauv tsiaj lossis cov nroj tsuag hauv kev ua kom zoo. Tshwj xeeb, symmetry yog hais txog ib qho kev sib txuas ntawm lub cev, qhov loj, zoo li, thiab tus txheeb ze txoj hauj lwm, nyob rau sab nraud ntawm kab sib faib los yog faib nyob ib ncig ntawm lub hauv paus taw tes lossis axis.
Vim li cas symmetry tseem ceeb hauv qhov xwm txheej?
Txhua yam khoom yog tus qauv tshiab lossis txawv nrog nws tus kheej symmetry. Cov kws tshawb fawb suav tias symmetry tawg yog cov txheej txheem ntawm kev tsim qauv tshiab. Kev sib koom ua ke yog qhov tseem ceeb vim tias lawv pab peb faib cov kev hloov pauv yam tsis tau xav txog hauv daim ntawvLos ntawm cov txheej txheem ntawm kev sib tsoo, cov qauv tshiab tsim.
Dab tsi yog qhov sib luag hauv koj ib puag ncig?
Tus kwv los yog ib qho daim duab yog hais tias yog symmetrical, yog hais tias ib kab muab tso rau ntawm daim duab, ces daim duab ntawm ib sab iav duab ntawm lwm sab. Cov kab uas tau kos rau ntawm daim duab symmetrical yog hais tias yog ib txoj kab ntawm symmetry.
Yuav ua li cas yog symmetry nrog piv txwv?
Symmetry yog tus cwj pwm uas ib yam dab tsi zoo ib yam ntawm ob sab ntawm ib qho axis. Ib qho piv txwv ntawm symmetry yog lub voj voog uas zoo ib yam ntawm ob sab yog tias koj quav nws raws nws txoj kab.
Puas muaj kev sib haum xeeb hauv qhov xwm txheej?
Ib qho tseem ceeb, tsis zoo li hauv kev ua lej, symmetry hauv biology yog ib txwm kwv yeesPiv txwv li, cov nplooj ntoo - thaum suav tias yog symmetrical - tsis tshua sib luag raws nraim thaum folded hauv ib nrab. Symmetry yog ib chav kawm ntawm cov qauv nyob rau hauv qhov uas muaj nyob ze-repetition ntawm tus qauv qauv, los ntawm kev xav los yog kev sib hloov.

Pfaffian qhov sib txawv qhov sib txawv yog dab tsi?
Daim ntawv dav dav ntawm Pfaffian equations hauv ob qhov sib txawv x thiab y yog P dx + Qdy=0, qhov twg P=P(x, y) thiab Q=Q(x, y) yog cov haujlwm ntawm x thiab y. … Yog hais tias peb tuaj yeem nrhiav cov haujlwm f=f (x, y) thiab g=g(x, y) xws li ω=gdf, ces ω=0 tuaj yeem raug txo kom df=0 nrog kev daws f(x, y)=c (c yog qhov tsis tu ncua) .
Nyob rau hauv science dab tsi yog qhov sib txawv ntawm qhov txawv?
Qhov txawv txav yog qhov sib txawv uas tau ntsuas lossis sim hauv qhov kev sim.1 Piv txwv li, hauv kev tshawb nrhiav seb qhov kev qhia qhia cuam tshuam li cas cov qhab nia xeem, qhov sib txawv nyob ntawm yuav yog cov neeg koom cov qhab nias xeem, vim qhov ntawd yog qhov ntsuas .
Dab tsi yog qhov sib txawv ntawm qhov sib txawv?
Nyob rau hauv nplooj ntawv no koj tuaj yeem tshawb pom 12 lub ntsiab lus, cov lus sib piv, cov lus qhia tsis zoo, thiab cov lus hais txog qhov tsis sib xws, xws li: antithesis , contraposition contraposition Nyob rau hauv ib txwm logic, contraposition yog ib daim ntawv ntawm tam sim no inference nyob rau hauv uas ib tug proposition yog inferred los ntawm lwm tus thiab qhov twg tus qub muaj rau nws cov ntsiab lus contradictory ntawm tus thawj logical proposition tus predicate
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
Nyob rau hauv fraunhoffer qhov sib txawv ntawm qhov sib txawv wavefront yog?
Nyob rau hauv qhov sib txawv no qhov xwm txheej thiab qhov sib txawv yoj pem hauv ntej yog spherical lossis cylindrical (b) Fraunhoffer diffraction: Hauv fraunhoffer diffraction, lub teeb qhov chaw thiab qhov taw qhia kev soj ntsuam nyob ntawm qhov kev ncua deb ntawm lub teeb meem.
