Nyob hauv qhov xwm txheej, emf yog tsim tawm thaum sib nqus teb hloov pauv tshwm sim los ntawm qhov chaw… induction, uas tsim ib tug voltage sib txawv ntawm lub generator terminals.
Lub zog ntawm electromotive yog dab tsi?
Kev ua haujlwm ntawm ib chav ntawm hluav taws xob, lossis lub zog uas tau txais ib chav hluav taws xob, yog lub zog hluav taws xob. Electromotive force yog tus yam ntxwv ntawm txhua lub zog muaj peev xwm tsav hluav taws xob nyob ib ncig ntawm lub voj voog.
Vim li cas electromotive quab yuam?
Electromotive force (EMF) yog qhov hluav taws xob tsim los ntawm txhua qhov chaw ntawm hluav taws xob xws li roj teeb lossis photovoltaic cell. Lo lus " quab yuam" yog me ntsis dag, vim EMF tsis yog lub zog, tab sis yog "muaj peev xwm" muab lub zog.
EMF txhais li cas?
Ib cheeb tsam ntawm hluav taws xob thiab sib nqus rog tshwm sim los ntawm hluav taws xob hluav taws xob. Cov kws tshawb fawb tab tom kawm seb EMFs los ntawm cov kab hluav taws xob, cov khoom siv hluav taws xob, thiab cov xov tooj wireless thiab xov tooj ntawm tes tuaj yeem ua rau mob qog noj ntshav lossis lwm yam teebmeem kev noj qab haus huv. Kuj hu ua electromagnetic field
piv txwv electromotive quab yuam yog dab tsi?
Electromotive quab yuam txhais tau tias yog lub zog hluav taws xob uas ua rau cov dej ntws tam sim no hauv ib lub voj voog. Ib qho piv txwv ntawm lub zog hluav taws xob yog voltage generated los ntawm lub roj teebLub zog ntawm ib chav tsev them nqi uas tau hloov pauv los ntawm tshuaj lom neeg, tshuab, lossis lwm yam khoom siv hluav taws xob rau hauv hluav taws xob hauv lub roj teeb lossis dynamo.

Ntau npaum li cas quab yuam rau cricoid siab?
Vanner thiab Asai pom zoo 30 N ntawm lub zog rau "cricoid siab", vim tias qhov no yuav tiv thaiv regurgitation ntawm oesophageal pressures mus txog 40 mmHg, uas yog deb tshaj qhov xav tau. nyob rau hauv feem ntau cov neeg mob. Txij thaum ntawd los, 30 N ntawm quab yuam tau raug coj los ua lub zog zoo tshaj plaws rau kev siv cricoid pres- sure .
Vim li cas kev quab yuam thiab kab mob ua rau muaj kev sib raug zoo?
Kev Ua Phem suav nrog kev sib cuam tshuam ntawm ob hom uas ib hom tau txais txiaj ntsig los ntawm kev tau txais cov peev txheej los ntawm thiab ua rau muaj kev puas tsuaj rau lwm tus. … Ntau tus kws tshawb fawb ecologists suav nrog cov kab mob cab hauv kev sib tham txog kev tua tsiaj.
Vim li cas van der waals quab yuam yog qhov muaj zog tshaj?
Lub zog muaj zog tshaj plaws yog hydrogen bonding, uas yog ib qho tshwj xeeb ntawm kev sib cuam tshuam ntawm dipole-dipole uas tshwm sim thaum hydrogen nyob ze (kho rau) lub ntsiab lus electronegative heev (xws li oxygen, nitrogen, lossis fluorine) .
Vim li cas pseudo quab yuam hu ua dag zog?
Qhov kev dag ntxias ntawm ib yam khoom tshwm sim raws li kev xav, es tsis yog lub zog tiag tiag, thaum tus ncej ntawm kev siv los piav qhia qhov kev txav ntawm ib qho khoom nrawm dua li piv rau inertial frame . Yuav hu li cas dag zog?
Vim li cas ducks quab yuam noj?
Tau tsim "foie gras" (lub ntsiab lus Fabkis txhais tau tias "fatty siab"), cov neeg ua haujlwm ram kav caj pas ntawm cov txiv neej ducks ob zaug hauv ib hnub, nqus mus txog 2.2 phaus ntawm cov nplej thiab rog rau hauv lawv lub plab, lossis geese.
