Lub elasticity ntawm cov khoom siv qhia kev sib tos ntawm tus nqi ntawm cov khoom siv thiab tus nqi lag luam rau cov khoom no. Hauv lwm lo lus, tau kawm paub qhov elasticity ntawm kev muab, peb yuav nkag siab qhov feem pua ntawm qhov ntau ntawm cov khoom lag luam ntawm lub khw yuav hloov thaum tus nqi nce / poob los ntawm 1%. Qhov coefficient ntawm elasticity tuaj yeem xam txheeb ze rau ntau yam ntawm ntau lawm, tab sis feem ntau nws yog tus nqi elasticity ntawm cov khoom siv uas tau muab xam.
Nws yog qhov tsim nyog
- - tshuab xam zauv;
- - tus nqi ntawm cov khoom ua ntej thiab tom qab tus nqi hloov;
- - qib theem ntawm tus nqi qub thiab hloov kho.
Cov Lus Qhia
Kauj ruam 1
Ua ntej, koj yuav tsum nrhiav kom paub tus nqi uas qhov kev hloov pauv tau hloov tom qab hloov tus nqi. Txhawm rau ua qhov no, rho tawm ntawm qhov ntsuas taw qhia tom qab tus nqi pauv Q1 tus nqi coj ua ntej nws hloov Q0.
Kauj ruam 2
Tshawb cov lej ntawm cov nqi khoom siv ua ntej thiab tom qab hloov pauv ntawm tus nqi rau cov khoom Q1 + Q0.
Kauj ruam 3
Xam tus nqi uas cov khoom lag luam tau hloov pauv. Txhawm rau ua qhov no, rho tawm tus nqi qub P0 ntawm tus nqi tom qab pauv hloov P1.
Kauj ruam 4
Ntxiv tus qauv qub thiab kho tus nqi P1 + P0.
Kauj ruam 5
Faib cov nqi hloov los ntawm thawj kauj ruam, Q1-Q0, los ntawm cov lej ntawm cov naj npawb no los ntawm kauj ruam thib ob, Q1 + Q0.
Kauj Ruam 6
Nrhiav qhov piv ntawm qhov ntsuas tau hauv theem peb thiab qib plaub. Faib P1-P0 los ntawm P1 + P0.
Kauj Ruam 7
Thaum kawg, nrhiav qhov sib piv ntawm cov zauv uas ua los ntawm cov kauj ruam 5 thiab 6. Tus lej tshwm sim yog qhov ntsuas ntawm tus nqi elasticity ntawm cov khoom.
Kauj ruam 8
Yog tias qhov ntsuas yog sib npaug rau ib qho, ces qhov no txhais tau hais tias thaum tus nqi nce nqi 1%, nws ua rau muaj qhov nce sib npaug ntawm cov khoom xa khoom ntawm lub khw. Yog hais tias lub elasticity ntawm mov yog ntau dua ib qho, ces cov mov yog elastic thiab ib qho kev nce nqi yuav ua rau kev nce ntxiv, thiab rov hloov dua siab tshiab.
