A tsis yog - Newtonian cov kua dej yog cov kua dej uas tsis ua raws Newton tus txoj cai ntawm viscosity, piv txwv li, tas li viscosity tsis muaj kev ntxhov siab. Hauv tsis yog - Newtonian kua, viscosity tuaj yeem hloov pauv thaum nyob rau hauv quab yuam mus rau cov kua ntau dua lossis ntau dua. Ketchup, piv txwv li, ua runnier thaum shaken thiab yog li no tsis yog - Newtonian kua.
Tom qab ntawd, qhov txawv ntawm Newtonian thiab tsis yog Newtonian yog dab tsi?
Newtonian Cov kua dej muaj qhov viscosity tas li uas tsis hloov, txawm tias lub siab siv rau cov kua. Tsis yog - Newtonian Cov kua dej tsuas yog qhov sib txawv - yog tias muaj zog txaus siv rau cov kua dej no, lawv cov viscosity yuav hloov.
Ib tug kuj yuav nug, yog huab cua yog Newtonian kua? Cov kua dej xws li dej, huab cua , ethanol, thiab benzene yog Newtonian . Qhov no txhais tau hais tias ib zajlus ntawm kev ntxhov siab rau cov shear tus nqi ntawm qhov kub thiab txias yog ib txoj kab ncaj nraim nrog txoj kab nqes mus tas li uas tsis muaj kev ywj pheej ntawm tus nqi shear. Peb hu qhov nqes hav qhov viscosity ntawm tus kua dej . Tag nrho cov pa roj Newtonian.
Ua li no, Newtonian system yog dab tsi?
A Newtonian Cov kua dej yog cov kua dej uas cov viscous stresses tshwm sim los ntawm nws cov ntws, ntawm txhua qhov chaw, yog linearly correlated rau lub zos strain rate-tus nqi hloov ntawm nws deformation lub sij hawm. Newtonian Cov kua dej yog cov qauv lej yooj yim tshaj plaws ntawm cov kua dej uas suav nrog viscosity.
Dab tsi yog qhov piv txwv ntawm cov kua dej tsis yog Newtonian?
A tsis yog - Newtonian kua dej yog a kua dej nws qhov viscosity yog qhov sib txawv raws li kev siv zog los yog quab yuam. Feem ntau txhua hnub piv txwv ntawm a tsis yog - Newtonian kua dej yog cornstarch yaj hauv dej. Cwj pwm ntawm Newtonian kua dej xws li dej tuaj yeem piav qhia tshwj xeeb ntawm qhov kub thiab txias.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Newtonian system yog dab tsi?
Cov kua dej Newtonian yog cov kua dej uas cov viscous ntxhov siab tshwm sim los ntawm nws cov dej ntws, ntawm txhua qhov chaw, yog linearly correlated rau lub zos strain rate-tus nqi ntawm kev hloov ntawm nws deformation lub sij hawm. Newtonian kua yog cov qauv lej yooj yim tshaj plaws ntawm cov kua dej uas suav nrog viscosity
