Los ntawm qhov kev xav ntawm cov tshuab ua kua, cov viscosity thiab elasticity ntawm cov kua siv lead ua kua tuaj yeem hais tau tias yog cov kua nrog cov khoom siv, uas yuav tsum muaj qhov sib txawv nyob ntawm qhov kev taw qhia ntawm lub zog siv. Nws zoo li pov ib tug ntoo luv luv rau hauv dej ntws ntws. Tus pas ntws nrog tus dej ntws, zoo nkaus li ntxhov thaum xub thawj. Tom qab ib pliag, qhov ntev axis ntawm tag nrho cov ntoo luv luv ib txwm ua raws li cov kev taw qhia ntawm cov dej ntws ntawm cov dej ntws, qhia txog cov kev khiav dej num nrog cov viscosity qis tshaj plaws thiab qis tshaj lub zog dawb ntawm kev khiav hauv lub cev qauv. Tsis tas li ntawd, cov kua muaju tsis tsuas yog muaj cov tshuaj tiv thaiv viscous nkaus xwb, tab sis kuj muaj cov tshuaj tiv thaiv elastic, tag nrho cov uas ua rau muaj kev cuam tshuam rau sab nraud. Yog li ntawd, thaum lub teeb nkag mus rau cov khoom siv lead ua kua, nws yuav inevitably mus rau hauv kev npaj ntawm cov kua siv lead ua kua molecules, ua ib tug natural deflection duab. Raws li rau cov qauv hluav taws xob hauv cov kua siv lead ua kua molecules, lawv txhua tus muaj zog electron conjugation zog muaj peev xwm. Yog li, thaum cov kua siv lead ua kua molecules raug rau sab nraud hluav taws xob, lawv tau yooj yim polarized los tsim induced dipole, uas kuj yog lub hauv paus ntawm kev sib cuam tshuam ntawm cov kua siv lead ua kua molecules. Cov kua siv lead ua kua siv nyob rau hauv cov khoom siv hluav taws xob siv hluav taws xob siv cov nyhuv photoelectric ntawm cov kua siv lead ua kua, tswj lawv los ntawm cov hluav taws xob sab nraud, thiab tau txais qhov ci ntsa iab thiab tsaus ntuj (tseem hu ua qhov muag pom qhov sib txawv) los ntawm cov khoom siv hluav taws xob ntawm cov kua siv lead ua kua molecules thiab lawv lub peev xwm tig lub teeb. , nyob rau hauv thiaj li yuav ua kom tiav imaging lub hom phiaj.
