piv txwv tus neeg muaj ob lub qhov muag sib txawv yog qhov tsis tshua muaj, tsuas yog 11 tawm ntawm txhua 1,000 tus neeg Asmeskas. Qhov kev tsis zoo no yog tshwm sim los ntawm ntau yam, thiab tuaj yeem txhim kho lub sijhawm.
2 qhov muag tsis tshua muaj xim yog dab tsi?
Green yog xim qhov muag tsawg tshaj plaws ntawm cov xim ntau dua. Tawm ntawm ob peb qhov tshwj xeeb, ze li txhua tus neeg muaj qhov muag xim av, xiav, ntsuab lossis qhov chaw nyob nruab nrab. Lwm cov xim xws li grey lossis hazel tsis tshua muaj.
Puas yog heterochromia tsawg?
Ua tiav heterochromia yog qhov tsis tshua muaj- tsawg dua 200,000 tus neeg Asmeskas muaj tus mob, raws li National Institutes of He alth. Qhov ntawd tsuas yog hais txog rau ntawm txhua 10,000 tus neeg.
Vim li cas kuv lub qhov muag thiaj muaj 2 xim sib txawv?
Qee tus neeg muaj ob lub xim sib txawv los ntawm tus mob hu ua heterochromia Tus mob no feem ntau tshwm sim los ntawm kev raug mob lossis raug mob ntawm qhov muag. Tsis tshua muaj, nws yuav tshwm sim los ntawm kev yug me nyuam xws li Waardenburg syndrome, Sturge-Weber syndrome, congenital Horner's syndrome, los yog Parry-Romberg syndrome.
Dab tsi yog qhov muag tsis tshua muaj xim?
Kev tsim cov melanin hauv iris yog dab tsi cuam tshuam qhov muag xim. Ntau melanin tsim cov xim tsaus, thaum tsawg dua ua rau lub qhov muag sib dua. qhov muag ntsuab yog qhov tsawg tshaj plaws, tab sis muaj cov ntaub ntawv qhia tsis tseeb uas qhov muag grey tseem tsis tshua muaj. Qhov muag xim tsis yog ib feem ntawm koj lub ntsej muag xwb.

Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
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) .
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
Lub network twg muaj qhov sib txawv ntawm qhov sib txawv?
Convolutional neural networks ( CNN's) tuaj yeem siv los kawm cov yam ntxwv nrog rau kev faib cov ntaub ntawv nrog kev pab ntawm cov duab thav duab. Muaj ntau hom CNN's. Ib chav kawm ntawm CNN's yog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov neural networks .
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.
