Refraction tshwm sim thaum lub teeb nkag mus rau lwm qhov nruab nrab ntawm ib qho nruab nrab, thiab qhov sib piv ntawm sine ntawm qhov teeb meem lub kaum sab xis yog tas li. Qhov piv no yog hu ua refractive index. txiv hmab txiv ntoo
Cov ntsiab lus ntawm soluble solids nyob rau hauv cov kua zaub yog proportional rau lub refractive index nyob rau hauv tej yam kev mob (tib yam kub thiab siab), yog li qhov refractive index ntawm txiv hmab txiv ntoo thiab zaub kua txiv yog txiav txim.
tus nqi, qhov concentration (qab zib cov ntsiab lus) ntawm txiv hmab txiv ntoo thiab zaub kua txiv tuaj yeem tau. Cov cuab yeej siv feem ntau yog tes- tuav refractometers, tseem hu ua iav tsom iav thiab tes- tuav saccharimeters.
Los ntawm kev ntsuas cov ntsiab lus soluble (qab zib) ntawm cov txiv hmab txiv ntoo thiab zaub, cov txiv hmab txiv ntoo thiab zaub zoo tuaj yeem nkag siab, thiab kev loj hlob ntawm cov txiv hmab txiv ntoo tuaj yeem kwv yees kwv yees. tes- tuav lub ntsuas qab zib
Nws yog cylindrical, muab cov kua qab zib tso rau hauv qhov qhib qhov zawj ntawm lub nraub qaum, kis nws tusyees, kaw lub hau, thiab tom qab ntawd taw tes lub ntsuas qab zib rau lub teeb, los ntawm sab xub ntiag.
Saib hauv lub qhov thiab koj tuaj yeem nyeem tau.
