Nyob rau hauv qhov kev nthuav qhia no koj kawm txog cov kua sib txawv li cas muaj cov viscosities sib txawv. Qee cov kua nplaum ntau dua li lwm tus Qhov no txhais tau tias lawv tuab dua thiab ntws yooj yim dua. Hais txog cov khoom, viscosity yog yooj yim npaum li cas cov khoom ntawm cov kua txav mus rau ib leeg.
Puas cov kua dej puas muaj viscosities?
Viscosity, cov kua ua tsis kam ntws, kuj yog cov yam ntxwv ntawm cov kua. Cov kua viscosity nyob ntawm qhov loj thiab cov duab ntawm nws cov khoom thiab cov kev nyiam ntawm cov khoom. Cov kua dej uas muaj viscosity siab, xws li zib ntab, ntws maj mam.
Vim li cas qee cov kua muaj viscosities txawv?
Vim li cas qee cov kua dej khov ntau dua li lwm tus? Loj, pob zeb molecules tsim kev sib txhuam ntau dua li me, du molecules Viscosity yog txiav txim siab nyob rau hauv loj los ntawm cov duab ntawm cov molecules hauv cov kua.… Cov kua yuav ntws los ntawm tus nqi qeeb dua li cov kua uas ua los ntawm cov molecules me me uas muaj qhov smoother.
dej puas muaj viscosities sib txawv?
Dej viscosity txawv nyob ntawm nws qhov kub thiab txias, thiab qhov kub siab dua, cov dej tsis khov. Dej viscosity ntawm, cia peb hais, 80 ° C yog 0.354 millipascals-thib ob.
Cov kua dej uas muaj viscosities sib txawv muaj tus nqi sib txawv?
Qhov kev tiv thaiv kom ntws tawm yog ncaj qha proportional rau lub viscosity η. Yog li, tus nqi ntws yog inversely proportional to the viscosity.

Puas muaj qhov sib txawv ntawm cov kab sib txuas hauv cov nroj tsuag?
Gap junctions yog ib hom kev sib txuas ntawm cov channel pom hauv cov tsiaj hlwb. Cov noob qes tsis muaj qhov sib txawv . Yog qhov sib txawv ntawm cov nroj tsuag? Gap junctions nyob rau hauv cov tsiaj hlwb zoo li plasmodesmata nyob rau hauv cov nroj tsuag hlwb nyob rau hauv uas lawv yog channels ntawm cov hlwb nyob ib sabuas tso cai rau kev thauj cov ions, as-ham, thiab lwm yam khoom uas ua rau lub hlwb.
Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
Puas muaj qhov sib txawv ntawm cov dej khov thiab cov slushies?
Tig tawm tsis muaj qhov sib txawv ntawm txhua qhov ntawm Slurpees thiab Icees. Lawv ob leeg yog tsim los ntawm Icee Company. Ib yam dej haus. Nws tsuas yog tias 7-Eleven muaj daim ntawv tso cai los hu rau lawv "Slurpees" . Puas Slurpees tib yam li Icees?
Lub network twg muaj qhov sib txawv ntawm qhov sib txawv?
Convolutional neural networks ( CNN's) tuaj yeem siv los kawm cov yam ntxwv nrog rau kev faib cov ntaub ntawv nrog kev pab ntawm cov duab thav duab. Muaj ntau hom CNN's. Ib chav kawm ntawm CNN's yog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov neural networks .
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
