Nyob rau hauv cov ntaub ntawv ntawm dL *, da *, db *, qhov siab dua tus nqi, qhov ntau dua qhov txawv ntawm qhov dimension. Delta E * (Tag nrho Xim Qhov txawv) yog xam raws li delta L*, ib*, b* xim qhov sib txawv thiab sawv cev qhov kev ncua deb ntawm ib kab ntawm tus qauv thiab tus qauv.
Yog li ntawd, Delta E yog dab tsi hauv kev ntsuas xim?
ΔE - ( Delta E , dE) Ib ntsuas ntawm kev hloov hauv kev pom kev pom ntawm ob qhov muab xim . Delta E yog ib qho kev ntsuas rau kev nkag siab tias tib neeg lub qhov muag pom tau li cas xim txawv. Lub sij hawm delta los ntawm kev ua lej, lub ntsiab lus hloov pauv hloov pauv lossis ua haujlwm. Nyob rau hauv ib txwm scale, lub Delta E tus nqi yuav nyob ntawm 0 txog 100.
Tom qab ntawd, lo lus nug yog, koj yuav xam Delta E li cas?
- Delta E txhais tau tias yog qhov sib txawv ntawm ob xim hauv qhov chaw L * a * b * xim.
- Cov nram qab no delta E qhov tseem ceeb yog siv tau universally:
- 0 - 1.
- CIE L*a*b*
- CIE L*a*b*
- Qhov sib txawv ntawm ob xim nyob rau hauv peb-dimensional L * a * b * xim chaw yog hu ua delta E.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov siv tau Delta E rau xim?
A Delta E ntawm 1 ntawm ob xim uas tsis kov ib leeg yog feem ntau suav hais tias yog qhov pom tau los ntawm qhov nruab nrab tib neeg soj ntsuam; ib Delta E nruab nrab ntawm 3 thiab 6 feem ntau suav hais tias yog ib qho txais tau phim hauv kev lag luam luam tawm ntawm cov ntawv luam tawm.
Dab tsi yog qhov zoo Delta E?
Yog ib Delta E tus naj npawb yog tsawg dua 1 ntawm ob xim uas tsis kov, nws yog NW nyuam qhuav perceivable los ntawm nruab nrab tib neeg soj ntsuam. A Delta E nruab nrab ntawm 3 thiab 6 feem ntau suav hais tias yog tus lej siv tau hauv kev ua lag luam luam tawm, tab sis cov xim sib txawv tuaj yeem pom los ntawm cov kws luam ntawv thiab cov duab kos duab.

Voltage poob: Parallel Circuit Qhov no txhais tau hais tias qhov hluav taws xob poob thoob plaws txhua qhov tsuas yog tag nrho qhov hluav taws xob ntawm lub voj voog muab faib los ntawm tus lej ntawm cov resistors hauv Circuit Court, lossis 24 V / 3 = 8 V
Yuav ua li cas koj xam pab neeg tshaj tawm hauv kev nyab xeeb?
Pab pawg neeg qhov nrawm rau kev rov ua dua yog sib npaug ntawm cov ntsiab lus rau tag nrho cov dab neeg ua tiav uas tau ntsib lawv Cov Lus Txhais Ua tiav (DoD). Raws li pab neeg ua hauj lwm ua ke dhau sij hawm, lawv qhov nruab nrab tshaj tawm (ua tiav zaj dab neeg cov ntsiab lus ib iteration) ua kom ntseeg tau thiab kwv yees
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Yuav ua li cas koj xam lub sij hawm nws yuav siv sij hawm mus ncig teb chaws?
Kwv yees seb koj yuav mus sai npaum li cas ntawm koj qhov kev mus ncig. Tom qab ntawd, faib koj qhov kev ncua deb ntawm koj qhov nrawm. Qhov no yuav muab rau koj anestimation ntawm koj lub sijhawm mus ncig. Piv txwv li, yog tias koj mus ncig yog 240 mais thiab koj yuav tsav 40 mais ib teev, koj lub sijhawm yuav yog 240/40 = 6hours
Yuav ua li cas koj xam lub sij hawm nws yuav siv ib yam khoom los poob?
Ntsuas qhov deb ntawm qhov khoom yuav poob hauv ko taw nrog tus pas ntsuas lossis ntsuas daim kab xev. Faib qhov kev ncua deb los ntawm 16. Piv txwv li, yog tias cov khoom yuav poob 128 ko taw, faib 128 los ntawm 16 kom tau 8. Xam cov square root ntawm cov kauj ruam 2 los nrhiav lub sij hawm nws yuav siv cov khoom poob hauv vib nas this
