Newtonian thiab non-Newtonian kua tsis ntev los no tau txais kev txaus siab tsis yog ntawm cov kws tshawb fawb nkaus xwb, tab sis kuj yog cov neeg zoo tib yam. Qhov no yog vim qhov tseeb tias cov kua dej uas tsis yog-Newtonian yooj yim ua nrog koj tus kheej tes thiab tsim nyog rau kev sim hauv tsev. Yuav pib nrog, cia peb txheeb xyuas seb hom tshuaj twg yog qhov dav dav. Newtonian kua ua raws li Newton txoj cai ntawm kev sib txhuam viscous, uas yog vim li cas nws tau txais nws lub npe. Raws li txoj cai lij choj no, cov kev ntxhov siab hauv cov dav hlau ntawm kev sib cuag ntawm cov khaubncaws sab nraud povtseg ntawm cov kua yog ncaj qha proportional rau lub derivative ntawm qhov tshaj tawm ntawm nws ntws nyob rau hauv cov kev taw qhia ib txwm rau cov dav hlau.
Nws suab nyuaj, tab sis nws yuav pom tseeb dua rau cov neeg nyeem yog tias peb hais tias cov kua Newtonian yog dej, roj thiab feem ntau ntawm cov kua dej uas paub txog peb hauv kev siv niaj hnub, uas yog, cov khoom khaws cia. lub xeev ntawm kev sib sau ua ke, txawm koj tsis tau ua nrog lawv (tshwj tsis yog peb tab tom tham txog evaporation lossis khov, tau kawg). Tab sis yog tias qhov kev vam khom tau piav qhia hauv cov ntsiab lus saum toj no yog qhov sib npaug, peb tuaj yeem tham txog cov kua dej uas tsis yog-Newtonian.
Cov kua dej no ib txwm muaj ntau yam, nws muaj cov molecules loj uas sib sau ua ke rau hauv cov iav siv lead ua, yog li cov viscosity ncaj qha nyob ntawm tus nqi ntws ntawm cov compound. Qhov ceev dua, qhov viscosity ntau dua. Ib feem, hom tshuaj no suav nrog cov kua thixotropic, uas yog, cov uas hloov viscosity dhau sijhawm, xws li putty lossis chocolate. Tsis tas li ntawd, qee cov kws tshawb fawb zoo li xav txog cov ntshav ua ib yam khoom uas tsis ua raws li Newton txoj cai ntawm kev sib txhuam, vim tias nws yog cov kua dej tsis sib xws, nws yog kev ncua ntawm plasma thiab ntau cov qe ntshav. Txhua tus kws kho mob yuav paub meej tias cov ntshav viscosity tuaj yeem sib txawv ntawm qhov sib txawv ntawm cov hlab ntsha, uas feem ntau yog pathology. Txawm li cas los xij, tsis yog txhua yam khoom muaj peev xwm ua tau zoo li metamorphoses.
Non-Newtonian kua tuaj yeem ua tau yooj yim hauv tsev. Koj yuav tsum noj 1.5 feem ntawm cov hmoov txhuv nplej siab (zoo tshaj plaws pob kws, tab sis qos yaj ywm yuav ua) thiab ib feem ntawm dej. Cov khoom xyaw yuav tsum sib tov maj mam kom tsis txhob muaj pob. Qhov zoo tshaj plaws, koj yuav tsum tau kis nws hauv ib txheej nyias nyias ntawm daim ntawv ci, tab sis, tau kawg, txhua qhov kev sib cuam tshuam tuaj yeem ntsib. Sim ua kom sai "shovel" cov kua nrog koj cov ntiv tes, thiab nws yuav zoo li zoo li cov yas khov khov. So koj cov ntiv tes thiab cov kua yuav ntws. Newtonian kua tsis muaj peev xwm ua tau zoo li no! Koj tuaj yeem nqa cov khoom hauv ib txhais tes thiab pib pov nws. Tsis ntev nws yuav dhau los ua kua thiab yas, thiab yog li ntawd nws yuav zoo li ua las voos hauv koj txhais tes - qhov no yog qhov pom kev nthuav dav heev!Yob cov kua rau hauv ib lub pob, nws yuav elastic thiab qab ntxiag, tab sis yog tias koj so koj lub xib teg, nws yuav kis tau. Nws yog qhov nthuav kom ntxiv dyes rau nws ua si nrog menyuam yaus. Qee tus mus ntxiv thiab txawm sim khiav ntawm cov kua dej uas tsis yog Newtonian, dov cov khoom ntawm nws, thiab lwm yam, tab sis rau cov kev sim no, tau kawg, ntau yam khoom xav tau ntau dua li kev sim hauv tsev. Koj tuaj yeem pom ntau cov ntawv tshaj tawm video thiab txuas ntxiv mus tshawb txog lub ntiaj teb txaus nyiam ntawm physics.
