Kev hloov pauv muaj txiaj ntsig vim nws ua rau nkag siab qhov teeb meem yooj yim dua hauv ib lub npe dua li lwm qhov. Oryou ua tau hloov nws mus rau hauv S domain (Laplace hloov ), thiab daws lub voj voog nrog cov lej yooj yim thiab tom qab ntawd hloov koj cov txiaj ntsig los ntawm S sau rov qab rau hauv lub sijhawm (inverse Laplace hloov ).
Ntawm no, vim li cas Laplace hloov pauv muaj txiaj ntsig?
Lub hom phiaj ntawm Hloov pauv yog to hloov zoo tib yam sib txawv sib npaug (ODEs) intoalgebraic equations, uas ua rau nws yooj yim dua los daws ODEs. Cov Hloov pauv yog ib tug generalized Fourier Hloov pauv , vim nws tso cai rau ib tug kom tau hloov ntawm cov haujlwm uas tsis muaj Fourier Hloov pauv.
Tsis tas li ntawd, vim li cas peb thiaj siv Fourier transform thiab Laplace transform? Laplace yog qhov zoo ntawm kev nrhiav cov lus teb topulses, kauj ruam ua haujlwm, delta zog, thaum Fourier yog qhov zoo rau cov teeb liab txuas ntxiv. Hloov pauv yog siv vim hais tias lub sij hawm-domain mathematical qauv ntawm cov tshuab yog feem ntau nyuaj sib txawv sib npaug.
Hauv qhov no, Fourier transforms siv rau dab tsi?
Cov Fourier Hloov yog ib qho tseem ceeb imageprocessing cuab tam uas yog siv rau decompose ib daim duab rau hauv nws cov khoom thiab cosine. Cov zis ntawm lub transformation sawv cev rau cov duab nyob rau hauv lub Fourier los yog zaus domain, thaum lub input duab yog lub spatial domainequivalent.
Laplace transforms siv nyob qhov twg?
Cov Hloov pauv tuaj yeem yog siv daws qhov sib npaug sib npaug thiab yog siv feem ntau inelectrical engineering. Cov Hloov pauv txo qhov sib npaug alinear sib txawv rau qhov sib npaug ntawm algebraic, uas tuaj yeem daws tau los ntawm cov cai ntawm algebra.

Vim li cas cov hnub qub dhau los ntawm kev hloov pauv hloov pauv?
Stellar evolution yog tus txheej txheem uas lub hnub qub hloov pauv nyob rau lub sijhawm. Cov hnub qub uas muaj tsawg kawg yog ib nrab ntawm lub hnub tuaj yeem pib tsim lub zog los ntawm kev sib xyaw ntawm helium ntawm lawv cov tub ntxhais, thaum lub hnub qub ntau dua tuaj yeem sib xyaw cov ntsiab lus hnyav dua raws li cov khoom sib xyaw ua ke
Vim li cas tom qab kev hloov pauv kev hloov pauv tseem ceeb?
Kev hloov pauv tom qab kev txhais lus (PTMs) xws li glycosylation thiab phosphorylation ua lub luag haujlwm tseem ceeb ntawm kev ua haujlwm ntawm hemostatic proteins thiab tseem ceeb heev hauv kev teeb tsa kab mob. Xws li theem nrab hloov pauv rau cov proteins hemostatic muaj ntau yam cuam tshuam rau lawv lub peev xwm los cuam tshuam nrog lwm cov proteins
Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation
Lub zog siv hluav taws xob txuag tau li cas thaum hloov pauv lossis hloov pauv?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias rau txhua qhov system, lub zog tsis tuaj yeem tsim lossis rhuav tshem; nws tsuas tuaj yeem hloov ntawm ib daim ntawv mus rau lwm qhov lossis hloov ntawm ib yam khoom mus rau lwm qhov. Mechanical zog los ntawm ob hom: lub zog muaj peev xwm, uas yog khaws cia lub zog, thiab lub zog kinetic, uas yog lub zog ntawm kev txav
Peb qhov laj thawj tseem ceeb ntawm kev hloov pauv hloov pauv yog dab tsi?
Allele frequencies nyob rau hauv ib tug pej xeem yuav hloov vim plaub lub hauv paus zog ntawm evolution: Natural Selection, Genetic Drift, Mutations thiab Gene Flow. Kev hloov pauv yog qhov kawg ntawm cov alleles tshiab hauv cov noob caj noob ces. Ob ntawm cov txheej txheem tseem ceeb tshaj plaws ntawm kev hloov pauv hloov pauv yog: Natural Selection thiab Genetic Drift
