Cov nqe lus twg yog txhais tau tias muaj kev sib npaug sib npaug ? Ntawm dynamic equilibrium , tus nqi ntawm pem hauv ntej thiab thim rov qab yog sib npaug. Ntawm dynamic equilibrium , tus nqi ntawm cov tshuaj tiv thaiv pem hauv ntej yog siab dua tus nqi ntawm cov tshuaj tiv thaiv rov qab. Ntawm dynamic equilibrium , cov lus teb rau pem hauv ntej thiab rov qab nres.
Nyob rau hauv no hais txog, nqe lus twg yog piav qhia txog cov tshuaj tiv thaiv nyob rau hauv dynamic equilibrium?
Qhov tseeb nqe lus yog at dynamic equilibrium tus tshuaj tiv thaiv txuas ntxiv tab sis tus nqi ntawm cov reactants thiab cov khoom tsis hloov. Qhov no yog vim ntawm kev sib npaug tus nqi ntawm pem hauv ntej tshuaj tiv thaiv sib npaug ntawm qhov rov qab tshuaj tiv thaiv yog li txawm tias cov tshuaj tiv thaiv tsis nres, tsis muaj kev hloov pauv hauv lub tshuaj tiv thaiv.
Ib sab saum toj no, dynamic equilibrium txhais li cas? Dynamic equilibrium . Hauv chemistry, thiab hauv physics, a dynamic equilibrium tshwm sim ib zaug ib tug reversible tshwm sim. Cov tshuaj hloov pauv ntawm cov reactants thiab cov khoom ntawm tus nqi sib npaug, txhais tau tias tsis muaj kev hloov pauv. Reactants thiab cov khoom raug tsim los ntawm tus nqi uas qhov concentration ntawm ob qho kev hloov pauv.
Ib tug kuj yuav nug, nqe lus twg kom raug txhais cov lus nug sib npaug?
Ntawm dynamic equilibrium , cov tshuaj tiv thaiv txuas ntxiv tab sis tus nqi ntawm cov reactants thiab cov khoom tsis hloov.
Dab tsi yog cov yam ntxwv ntawm dynamic equilibrium?
(a) Cov concentration (los yog siab ) ntawm reactants thiab cov khoom tseem nyob tas li (los yog tsis hloov) lub sij hawm. (b) Tus nqi ntawm cov tshuaj tiv thaiv rau pem hauv ntej yog sib npaug rau tus nqi ntawm cov tshuaj tiv thaiv rov qab (ob qho tib si rau pem hauv ntej thiab rov qab cov tshuaj tiv thaiv ua rau ntawm qhov sib npaug).

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
Cov nqe lus twg zoo tshaj plaws piav qhia txog qhov tseem ceeb ntawm cov lus qhia muaj nuj nqis?
Qhov tsis suav nrog tus nqi ntawm ib qho kev qhia rational yog qhov tseem ceeb uas tus denominator ntawm qhov kev qhia yog xoom. Tsis tas li ntawd, tus naj npawb ntawm zeros ntawm ib tug polynomial yeej ib txwm tsawg dua los yog sib npaug rau degree ntawm lub polynomial. Yog li ntawd, tus naj npawb ntawm cov txiaj ntsig tsis suav nrog cov lus qhia muaj txiaj ntsig tsis tuaj yeem tshaj li qib ntawm tus lej
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
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
