Kev xav tau elastic txhais tau hais tias yuav muaj kev hloov pauv ntau ntxiv ntawm qhov xav tau ntawm qhov zoo lossis kev pabcuam dua li tus nqi ntawm qhov zoo lossis kev pabcuam. Qhov kev thov zoo kawg nkaus inelastic txhais tau hais tias tsis hais tus nqi, qhov xav tau ntawm qhov zoo lossis kev pabcuam tseem nyob tas li.
Qhov kev thov twg yog qhov elastic?
lej, qhov xav tau elastic yog lub npe hu ua ntau dua li qhov kev thov elastic (e p >1). Piv txwv li, yog tias tus nqi ntawm cov khoom lag luam nce los ntawm 20% thiab qhov kev thov ntawm cov khoom txo qis los ntawm 25%, ces qhov kev thov yuav yog elastic.
Kev sib txheeb elastic thov yog dab tsi?
Kev xav tau elastic yog hais txog qhov kev thov thaum qhov kev hloov pauv hauv qhov kev thov ntau dua li qhov kev hloov pauv ntawm tus nqi zoo. Tus lej tus nqi ntawm qhov xav tau ntawm qhov sib txawv ntawm ib mus rau infinity.
Thaum xav tau yog qhov elastic qhov kev thov nkhaus yog?
Qhov kev thov rau qhov zoo yog hais tias elastic (los yog elastic) thaum nws PED ntau dua ib qho. Hauv qhov no, kev hloov pauv ntawm tus nqi muaj ntau tshaj qhov sib npaug ntawm qhov ntau ntawm qhov xav tau zoo.
Thaum tus nqi elasticity ntawm kev thov yog qhov elastic?
Thaum tus nqi elasticity ntawm kev thov yog qhov elasticity (−∞ < Ed < −1), qhov feem pua ntawm cov khoom xav tau ntau dua li tus nqi. Li no, thaum tus nqi nce, tag nrho cov nyiaj tau los poob, thiab vice versa.
