kev sib npaug . Ib qho xwm txheej uas txhua tus cuam tshuam kev ua yeeb yam tso tseg ib leeg, kom qhov xwm txheej zoo li qub lossis sib npaug. Hauv physics , kev sib npaug tshwm sim los ntawm kev tshem tawm ntawm lub zog ua rau ib yam khoom.
Kuj tseem paub yog, qhov sib npaug hauv physics yog dab tsi?
Equilibrium, nyob rau hauv physics , qhov xwm txheej ntawm lub kaw lus thaum tsis yog nws lub xeev ntawm kev txav los yog nws lub zog sab hauv lub xeev yuav hloov nrog lub sijhawm.
Kuj Paub, vim li cas qhov sib npaug tseem ceeb hauv physics? Equilibrium thiab Statics. Thaum tag nrho cov zog uas ua rau ib qho khoom sib npaug, ces cov khoom tau hais tias nyob rau hauv lub xeev kev sib npaug . Nco ntsoov tias ob yam khoom nyob ntawm kev sib npaug vim lub zog uas ua rau lawv sib npaug; txawm li cas los xij, tus kheej lub zog tsis sib npaug.
Tom qab ntawd, lo lus nug yog, qhov sib npaug txhais li cas?
Equilibrium txhais tau tias yog lub xeev ntawm kev tshuav nyiaj li cas los yog qhov xwm txheej ruaj khov uas tawm tsam cov tub rog tawm tsam ib leeg thiab qhov tsis muaj kev hloov pauv tshwm sim. Ib qho piv txwv ntawm kev sib npaug yog nyob rau hauv kev lag luam thaum muab khoom thiab kev thov sib npaug.
3 hom equilibrium yog dab tsi?
Muaj peb hom equilibrium : ruaj khov, tsis ruaj khov, thiab nruab nrab. Cov duab thoob plaws qhov module no qhia txog ntau yam piv txwv.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Qhov sib npaug tshuaj sib npaug txhais li cas?
Cov tshuaj sib npaug yuav tsum sib npaug kom nws ua raws li txoj cai ntawm kev txuag ntawm huab hwm coj. Ib qho kev sib npaug tshuaj sib npaug tshwm sim thaum tus naj npawb ntawm cov atoms sib txawv ntawm cov ntsiab lus hauv cov reactants sab sib npaug ntawm cov khoom sab. Kev sib npaug tshuaj sib npaug yog cov txheej txheem ntawm kev sim thiab ua yuam kev
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
