Ob leeg yog qhov sib npaug sib txawv (kev sib npaug uas suav nrog derivatives). ODEs koom nrog cov derivatives hauv ib qho kev sib txawv, qhov PDEs koom nrog cov derivatives hauv ntau qhov sib txawv. Yog li ntawd tag nrho cov ODEs tuaj yeem raug saib raws li PDEs. PDEs feem ntau nyuaj rau nkag siab cov kev daws teeb meem ntau dua li ODEs
Puas yog ODEs lossis PDEs nyuaj dua?
PDEs feem ntau nyuaj rau kev nkag siab ntau dua li ODEs. Yeej txhua qhov kev xav loj txog ODEs tsis siv rau PDEs. Nws yog ntau tshaj qhov laj thawj tseem ceeb uas muaj ntau qhov sib txawv.
PDEs nyuaj?
Feem ntau, qhov sib npaug sib txawv ib nrab yog qhov nyuaj dua los daws kev tshuaj ntsuam ntau duayog qhov sib npaug sib txawv. … Cov hauv qab no yog cov piv txwv ntawm cov kev sib npaug sib txawv tseem ceeb uas feem ntau tshwm sim hauv cov teeb meem ntawm lej physics.
Dab tsi yog qhov txawv ntawm ODEs thiab PDEs?
Ib qho piv txwv sib txawv sib txawv (ODE) muaj qhov sib txawv ntawm qhov sib txawv ntawm tsuas yog ib qho sib txawv, ib feem ntawm qhov sib txawv (PDE) muaj qhov sib txawv nrog hwm rau ntau qhov sib txawv ntawm tus kheej.
Vim li cas ib feem ntawm qhov sib npaug sib txawv nyuaj?
Vim lawv muaj qib kev ywj pheej ntau dua li ODEs lawv feem ntau nyuaj rau tawg ODE arbitrary feem ntau tsis analytically solvable txawm tab sis kuv tau txais koj cov ntsiab lus. Koj zoo li tau tsom mus rau qhov tsis ncaj ncees lawm ntawm no. PDE zoo li ODE tab sis muaj ntau qhov sib txawv (tsawg dua yam tsis tas li, tsis ntxiv).

Hais txog aluminium vs steel qhov hnyav - steel paub tias hnyav dua thiab nyuaj ntawm ob, feem ntau ua tsaug rau ua ntej hais txog cov pa roj carbon ntau - ntau cov pa roj carbon ntau, qhov hnyav nws yuav yog. Txawm li cas los xij, qhov ntxiv ntawm qhov muaj cov khoom hnyav yog qhov tseem yog cov khoom siv ruaj khov dua .
Vim li cas cov laj thawj yuam kev nyuaj dua nrhiav?
Logical yuam kev nyuaj dua nrhiav vim lawv tsis ua rau muaj lus yuam kevKev ua yuam kev yog qhov yuam kev hauv kev xav los ntawm tus programmer, tab sis nws tsis yog qhov yuam kev hauv lub programming lus. Ib qho piv txwv ntawm qhov kev ua yuam kev yuav muab faib los ntawm 2.
Kev nyuaj siab puas tuaj yeem sau qhov nyuaj?
Summary: Kev nyuaj siab los yog Dilemna? Ib qho "kev nyuaj siab" yog ib qho kev xaiv nyuaj lossis teeb meem, feem ntau muaj ob lossis ntau qhov kev xaiv uas tsis xav tau. Qee tus neeg ua yuam kev ntawm kev sau lo lus no nrog "
Puas siab dua lossis qis dua bitrate zoo dua?
A tus nqi siab dua feem ntau txhais tau hais tias lub suab zoo dua"Bitrate yuav txiav txim siab lub suab ncaj ncees," hais tias tus tsim khoom thiab tus kws tshaj lij Gus Berry. "Koj tuaj yeem muaj lub suab kaw zoo tshaj plaws ntawm txhua lub sijhawm, tab sis yog tias koj ua si nrog tus nqi qis, nws yuav ua suab tsis zoo rau lwm qhov kawg.
Dab tsi yog qhov nyuaj nyuaj?
Richeson Artists Untempered Hardboard Panels yog ib qho kev lag luam, lub teeb yuag, thiab ntau yam khoom nrogntau ntau yam kev kos duab thiab khoom siv tes ua. Lawv muaj lub ntsej muag du rau pleev xim uas muab kev txhawb nqa nruj tab sis tsis muaj qhov hnyav ntau .
