Hauv chemistry, kev sib hloov ([α]) yog ib yam khoom ntawm chiral chemical compound. Yog muaj peev xwm ua tau tig Lub dav hlau ntawm polarization ntawm lub dav hlau-polarized lub teeb, nws tau hais tias yog "optically nquag". Kev sib hloov tshwj xeeb yog ib tug intensive khoom, txawv nws los ntawm ntau yam phenomenon ntawm optical kev sib hloov.
Xav txog qhov no, dab tsi yog qhov kev sib hloov hauv polarimeter?
Kev sib hloov tshwj xeeb . Kev sib hloov tshwj xeeb , [α], yog ib qho cuab yeej tseem ceeb ntawm cov tshuaj chiral uas tau qhia tias yog lub kaum sab xis uas cov khoom ua rau lub teeb polarized rau tig ntawm qhov kub thiab txias, wavelength, thiab concentration.
Tom qab ntawd, lo lus nug yog, dab tsi yog kev sib hloov hauv optics? Kev txhais ntawm kev sib hloov .: angle of kev sib hloov nyob rau hauv degrees ntawm lub dav hlau ntawm polarization ntawm ib lub teeb ntawm lub teeb monochromatic uas dhau los ntawm lub raj 1 decimeter ntev uas muaj cov tshuaj nyob rau hauv kev daws ntawm ib tug concentration ntawm 1 gram ib millimeter nyob rau hauv ib tug polarimeter.
Tsuas yog li ntawd, koj yuav ua li cas xam cov kev sib hloov los ntawm kev sib hloov kho qhov muag?
Hloov ua lwm yam kev sib hloov rau kev sib hloov , faib cov pom kev sib hloov los ntawm cov concentration hauv g / mL thiab txoj kev ntev hauv decimeters (dm).
Puas yog kev sib hloov tshwj xeeb nyob ntawm qhov concentration?
Cov kev sib hloov tshwj xeeb yog ib yam khoom- tshwj xeeb lub cev parameter, uas ua tau yuav tau txiav txim los ntawm ib tug porimeter. Nws nyob ntawm ntawm qhov kub thiab qhov wavelength ntawm lub teeb. Rau qee cov qauv no tus nqi nyob ntawm ntawm concentration ib yam nkaus.

Dab tsi yog qhov txawv ntawm lub teeb pom kev nyuaj thiab muag muag?
Qhov sib txawv ntawm lub teeb mos thiab lub teeb nyuaj. Lub teeb nyuaj ua rau qhov sib txawv, tawv-edged ntxoov ntxoo. Lub teeb mos ua rau cov duab ntxoov ntxoo uas tsis tshua pom. Ib hnub tshav ntuj yog lub teeb nyuaj
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm qhov nrawm thiab nrawm?
Kev sib piv daim duab piv rau Kev Sib Piv Ceev Ceev Tus Nqi Hloov ntawm qhov kev ncua deb Hloov pauv hloov thaum lub cev rov qab mus rau nws qhov chaw pib Yuav tsis xoom Yuav yog xoom Tsiv khoom Ceev ntawm cov khoom txav tsis tuaj yeem tsis zoo. Kev nrawm ntawm cov khoom txav tuaj yeem yog qhov zoo, tsis zoo lossis xoom
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov kev sib raug zoo ntawm kev ua lej ntawm qhov kev nyuaj siab khov kho thiab Mollality?
Kev nyuaj siab qhov chaw khov kho yog cov cuab yeej sib koom ua ke pom hauv cov kev daws teeb meem uas tshwm sim los ntawm kev qhia txog cov kuab tshuaj molecules rau cov kuab tshuaj. Cov ntsiab lus khov ntawm cov kev daws yog tag nrho qis dua li cov kuab tshuaj ntshiab thiab yog ncaj qha proportional rau molality ntawm cov kuab tshuaj
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
