Hloov ua lwm yam pom kev sib hloov rau kev sib hloov , faib pom kev sib hloov los ntawm concentration hauv g / mL thiab txoj kab ntev hauv decimeters (dm).
Yog li ntawd, dab tsi yog tus qauv ntawm kev sib hloov tshwj xeeb?
CRC Phau Ntawv Qhia ntawm Chemistry thiab Physics txhais kev sib hloov Raws li: Rau cov khoom siv kho qhov muag, txhais los ntawm [α]θλ = α / γl, qhov twg α yog lub kaum sab xis los ntawm lub dav hlau polarized lub teeb yog tig los ntawm kev daws ntawm huab hwm coj concentration γ thiab txoj kev ntev l.
Qhov thib ob, dab tsi yog cov units ntawm kev sib hloov tshwj xeeb? Kev sib hloov tshwj xeeb ntawm qhov sib xyaw ua ke yog cov yam ntxwv ntawm cov khoom sib xyaw kom ntev li ntev tau qhov kub thiab txias, yoj ntev ntawm qhov teeb , thiab, yog tias siv cov tshuaj rau kev sim, cov kuab tshuaj tau teev tseg. Cov units ntawm kev sib hloov tshwj xeeb yog degreesmLg-1ua dm-1.
Ib yam li ntawd, koj yuav ua li cas xam enantiomeric ntau dhau los ntawm kev sib hloov tshwj xeeb?
Rau xam tus enantiomeric ntau dhau , koj faib cov pom kev sib hloov los ntawm qhov siab tshaj plaws kev sib hloov ntawm tshaj enantiomer.
Koj txhais li cas los ntawm kev sib hloov tshwj xeeb?
Kev sib hloov tshwj xeeb . Hauv stereochemistry, lub kev sib hloov ntawm ib qho tshuaj compound [α] txhais tau tias yog lub kaum sab xis pom ntawm optical kev sib hloov α thaum lub dav hlau-polarized lub teeb dhau los ntawm cov qauv nrog txoj kab ntev ntawm 1 decimeter thiab cov qauv concentration ntawm 1 gram ib 1 milliliter.

Cov ntaub ntawv dab tsi tuaj yeem txiav txim siab los ntawm kev soj ntsuam ib lub spectrum?
Lub stellar spectrum tuaj yeem nthuav tawm ntau yam khoom ntawm cov hnub qub, xws li lawv cov tshuaj muaj pes tsawg leeg, qhov kub thiab txias, qhov ntom ntom, qhov loj, qhov deb, luminosity, thiab kev txheeb ze ntawm kev siv Doppler hloov kev ntsuas
Yuav ua li cas taxonomists soj ntsuam evolutionary kev sib raug zoo ntawm cov kab mob?
Yuav ua li cas taxonomists soj ntsuam evolutionary relationships ntawm cov kab mob? Taxonomists tshuaj xyuas cov yam ntxwv ntawm lub cev. Los ntawm kev sib piv cov qauv sib txawv thiab cov yam ntxwv, lawv muaj peev xwm tohypothesize txog kev sib raug zoo ntawm cov kab mob
Sutton txoj kev soj ntsuam txhawb li cas chromosome txoj kev xav ntawm kev qub txeeg qub teg?
Sutton cov kev soj ntsuam txhawb cov chromosome txoj kev xav ntawm kev qub txeeg qub teg vim Sutton pom tias txhua tus poj niam txiv neej ntawm tes muaj ib nrab ntawm cov chromosomes ua lub cev cell, uas txhais tau hais tias cov xeeb ntxwv tau txais ib qho allele los ntawm khub niam txiv. Zoo li cov hlaws dai ntawm ib txoj hlua, thiab tib yam ntawm ob lub chromosomes
Cov kev soj ntsuam soj ntsuam dab tsi qhia tias muaj kev hloov tshuaj lom neeg tshwm sim?
Kev soj ntsuam uas qhia tias muaj kev hloov pauv tshuaj muaj xws li kev hloov xim, hloov pauv kub, lub teeb muab tawm, tsim ua npuas, tsim cov nag lossis daus, thiab lwm yam
Yuav ua li cas koj yuav soj ntsuam cov nyhuv ntawm lub teeb siv ntawm tus nqi ntawm photosynthesis?
Cov nyhuv ntawm lub teeb siv ntawm photosynthesis tuaj yeem tshawb xyuas hauv cov nroj tsuag dej. Qhov kev siv lub teeb yog proportional rau qhov kev ncua deb - nws yuav txo qis raws li qhov deb ntawm lub teeb nce - yog li lub teeb siv rau kev tshawb nrhiav tuaj yeem sib txawv los ntawm kev hloov qhov kev ncua deb ntawm lub teeb mus rau cov nroj tsuag
