A muab faib coefficient yog qhov piv ntawm cov concentration ntawm cov khoom hauv ib qho nruab nrab lossis theem (C1) mus rau qhov concentration nyob rau theem ob (C2) thaum ob qhov concentrations ntawm equilibrium; uas yog, muab faib coefficient = (C1/C2)sib npaug. Cov units ntawm C1 thiab C2 tej zaum yuav txawv.
Ib yam li ib tug yuav nug, koj ua li cas txiav txim siab qhov sib faib coefficient ntawm cov tshuaj?
Cov muab faib coefficient ntawm cov tshuaj tej zaum txiav txim siab los ntawm co nws nrog qhov sib npaug ntawm ob qhov sib npaug ntawm cov kuab tshuaj (cov organic txheej, uas yog saturated nrog dej, thiab cov aqueous. tshuaj daws) kom txog thaum muaj kev sib npaug. Cov ntsiab lus ntawm tshuaj nyob rau hauv ib qho ntawm cov txheej yog txiav txim siab thiab tus nqi raug xam.
Tsis tas li ntawd, dab tsi yog suav tias yog qhov sib faib siab coefficient? … unit of ntsuas hu ua muab faib coefficient . Qhov ntau dua qhov solubility ntawm ib yam khoom, lub siab dua nws muab faib coefficient , thiab cov siab dua tus muab faib coefficient , cov siab dua lub permeability ntawm daim nyias nyias rau cov khoom tshwj xeeb.
Yog li, qhov sib faib coefficient hauv chromatography yog dab tsi?
Partition Coefficient . Cov muab faib coefficient yog lub equilibrium kev faib tawm ntawm ib qho kev ntsuas nruab nrab ntawm theem qauv thiab theem roj. Cov qauv yuav tsum tau npaj kom ua kom qhov siab tshaj plaws ntawm cov khoom tsis hloov pauv hauv lub taub hau thiab txo qis qhov tsis xav tau los ntawm lwm cov tebchaw hauv cov qauv matrix.
Dab tsi yog qhov pom kev sib faib coefficient?
Cov pom meej muab faib coefficient (log P,,,), raws li qhia ntawm no, sawv cev rau kev faib tawm ntawm cov sums ntawm ob qho tib si ionized thiab non-ionized solute molecules ntawm ob theem ntawm kev xeem system.

Yuav ua li cas koj xam qhov hnyav thiab qhov sib npaug ntawm lub dav hlau?
Ntxiv tag nrho cov sijhawm mus nrhiav lub sijhawm tag nrho. Faib tag nrho lub sijhawm los ntawm qhov hnyav tag nrho kom pom qhov nruab nrab ntawm lub ntiajteb txawj nqus. Nrhiav tag nrho qhov hnyav thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm qhov nruab nrab ntawm lub ntiajteb txawj nqus daim ntawv qhia hauv koj lub dav hlau POH los txiav txim seb lub dav hlau puas nyob hauv qhov txwv
Qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov sib faib coefficient yog dab tsi?
Ib qho inverse linear kev sib raug zoo tau pom ntawm qhov kub thiab txias thiab qhov sib faib coefficient. CEEB TOOM: Nyob rau hauv ib qho kev ntsuas kub, qhov sib faib coefficients isoflurane thiab sevoflurane txo qis thaum qhov kub nce. Sevoflurane qhia tau hais tias muaj kev solubility siab hauv Oxygent (TM) piv rau isoflurane
Yuav ua li cas koj muab cov matrices ntawm lub graphing tshuab xam zauv?
Kauj ruam 1: Nkag mus rau thawj matrix rau hauv lub laij lej. Txhawm rau nkag mus rau matrix, nias [2ND] thiab [x−1]. Kauj ruam 2: Nkag mus rau lub matrix thib ob rau hauv lub tshuab xam zauv. Nias [2ND] thiab [x−1]. Kauj ruam 3: Nyem [2ND] thiab [MODE] tawm ntawm lub vijtsam matrix. Kauj ruam 4: Xaiv matrix A thiab matrix B hauv NAMES ntawv qhia zaub mov kom pom cov khoom
Yuav ua li cas koj xam chi square faib?
Chi-Square Distribution Qhov nruab nrab ntawm qhov kev faib tawm yog sib npaug rau cov qib kev ywj pheej: μ = v. Qhov sib txawv yog sib npaug rau ob npaug ntawm cov qib kev ywj pheej: σ2 = 2 * v. Thaum cov qib kev ywj pheej ntau dua tshaj los yog sib npaug rau 2, tus nqi siab tshaj plaws rau Y tshwm sim thaum Χ2 = v - 2
Qhov sib faib coefficient ntawm 1 txhais li cas?
Hauv kev tshawb fawb tshuaj thiab kws tshuaj, ob theem feem ntau yog cov kuab tshuaj. Feem ntau, ib qho ntawm cov kuab tshuaj yog dej, thaum qhov thib ob yog hydrophobic, xws li 1-octanol. Li no qhov sib faib coefficient ntsuas yuav ua li cas hydrophilic ('dej-hlub') lossis hydrophobic ('dej-fearing') tshuaj lom neeg yog
