LMEC-12 Kev Ntsuas Viscosity ntawm Cov Kua - Txoj Kev Capillary Duab Tshwj Xeeb

LMEC-12 Kev Ntsuas Cov Kua Viscosity - Txoj Kev Capillary

Kev Piav Qhia Luv:

Cov kua viscosity tsis yog tsuas yog siv dav hauv kev tsim kho thiab kev tsim khoom siv thev naus laus zis xwb, tab sis kuj ua lub luag haujlwm tseem ceeb hauv biology thiab tshuaj. Piv txwv li, kev ntsuas qhov loj ntawm cov ntshav viscosity yog ib qho ntawm cov cim tseem ceeb ntawm kev noj qab haus huv ntawm tib neeg cov ntshav. Piv nrog rau txoj kev poob pob, txoj cai ntws ntawm cov kua viscous hauv cov raj capillary ntsug yog siv rau hauv qhov kev sim no. Nws muaj qhov zoo ntawm cov qauv me me, cov ntsiab lus kub sib txawv thiab qhov ntsuas tau zoo. Tshwj xeeb tshaj yog haum rau cov kua viscosity qis, xws li dej, cawv, dej, thiab lwm yam. Kev siv cov cuab yeej no tsis yog tsuas yog nthuav cov tub ntxhais kawm txoj kev paub, tab sis kuj txhim kho lawv lub peev xwm ua haujlwm sim.
