HETP yog ib lub ntsiab lus rau qhov siab sib npaug rau Theoretical Phaj. Nws tshwm sim los ntawm Plate Theory thiab muaj pes tsawg tus sib npaug ntawm kab ntev muab faib los ntawm cov lej ntawm cov phiaj xwm theoretical hauv kem (thiab hauv kev xyaum yog ntsuas li no).
Ntawm no, Hetp yog dab tsi nyob rau hauv packed kem?
Ntim Qhov siab (Dilute): HETP . HETP (Qhov siab sib npaug rau Theoretical Phaj) Raws li peb tau sau tseg, tsis yog lub tais (phaj) kem , a ntim kab tuaj yeem siv rau ntau yam haujlwm xws li kev ua haujlwm tas mus li lossis batch distillation, lossis kev nqus roj.
Tsis tas li ntawd, Hetp thiab HTU yog dab tsi? Nyob rau hauv ib kem packed, HETP (Qhov siab sib npaug rau Theoretical Pate) lossis HTU (Qhov siab ntawm Kev Hloov Chaw) yog siv los txheeb xyuas qhov siab ntawm kab ke nrog cov lej theoretical theem tau los ntawm cov qauv tsim qauv xws li McCabe-Thiele lossis Ponchon-Savaritt.
Tom qab ntawd, Hetp suav li cas?
Phaj Height Chromatography Formula Koj tuaj yeem siv qhov "qhov siab sib npaug rau lub phaj theoretical" ( HETP ) hauv equation HETP = A + B / v + Cv rau Eddy-diffusion lub sij hawm A, longitudinal diffusion lub sij hawm B, tsis kam mus rau huab hwm coj hloov coefficient C thiab linear tshaj tawm v.
Qhov siab sib npaug li cas rau lub phaj theoretical?
HETP ( Qhov siab sib npaug rau Theoretical Phaj (stage or phaj )) yog qhov sib nrug ntawm lub tais sib faib los ntawm qhov sib npaug tag nrho cov tais ua haujlwm [82].

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
