Delta E ( CMC ) Cov txheej txheem xim sib txawv ntawm Pawg Saib Xyuas Kev Ntsuas Xim (the CMC ) yog ib qho qauv siv ob qhov tsis muaj l thiab c, feem ntau qhia raws li CMC (l:c). Feem ntau siv qhov tseem ceeb rau kev lees paub yog CMC (2:1) thiab rau perceptibility yog CMC (1:1).
Yog li ntawd, lub ntsiab lus ntawm Delta E yog dab tsi?
ΔE - ( Delta E , dE) Kev ntsuas kev hloov pauv hauv kev pom kev pom ntawm ob lub xim muab. Delta E yog ib qho kev ntsuas rau kev nkag siab tias tib neeg lub qhov muag pom qhov sib txawv ntawm cov xim. Lub sij hawm delta los ntawm lej, lub ntsiab lus hloov nyob rau hauv ib tug variable los yog muaj nuj nqi. Nyob rau hauv ib txwm scale, lub Delta E tus nqi yuav nyob ntawm 0 txog 100.
Tsis tas li ntawd, Delta E yog dab tsi hauv cov xim? Delta E , ΔE lossis dE, yog ib txoj hauv kev los ntsuas qhov pom qhov sib txawv, lossis kev ua yuam kev ntawm ob xim ua lej. Nws yog qhov tseem ceeb heev rau kev txheeb xyuas "kev sib ze" ntawm pleev xim mus rau ib qho qauv scanned thiab muaj kev siv pom tseeb hauv kev lag luam thiab kev lag luam tswj kom zoo. Cov Delta E system tsis muaj tus lej tsis zoo.
Ua raws li qhov no hauv kev txiav txim siab, 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.
Delta E formula yog dab tsi?
Delta E * (Tag nrho cov xim sib txawv) yog xam raws li delta L *, a *, b * xim txawv thiab sawv cev rau qhov kev ncua deb ntawm kab ntawm tus qauv thiab tus qauv.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
