Rate vs Ratio
Tus nqi thiab qhov piv yog tus lej ntawm tib yam. Lawv feem ntau piav qhia qhov sib npaug ntawm ib qho ntawm lwm tus. Ob qho no yog siv hauv kev ua lej kom nkag siab zoo dua thiab paub qhov txawv ntawm qhov xwm txheej lossis tus nqi. Ua li no, nws yuav yooj yim dua kom paub qhov txawv thiab paub tus nqi ntawm lwm tus.
Rate
Tus nqi yog kev sib raug zoo ntawm ob qhov kev ntsuas uas muaj ntau yam units. Qhov ntau los yog chav tsev, qhov twg ib yam khoom tsis tau qhia, feem ntau yog tus nqi ntawm ib lub sijhawm. Txawm li cas los xij, tus nqi ntawm kev hloov pauv tuaj yeem raug hu ua ib chav tsev ntawm qhov ntev, qhov hnyav lossis sijhawm. Hom kev ntsuas feem ntau yog lub sijhawm, zoo li lub plawv dhia thiab ceev. Thaum nws los piav txog cov nqi tsev, lo lus "ib" yog siv los faib 2 qhov kev ntsuas uas siv los suav tus nqi.
Ratio
Ratio yog kev sib txuas ntawm 2 tus lej uas muaj tib hom. Tej zaum nws yuav muaj feem rau cov diav, units, cov menyuam kawm ntawv, cov neeg thiab cov khoom. Nws yog feem ntau qhia raws li a: b lossis a yog rau b. Qee lub sij hawm, nws tau hais txog lej raws li qhov loj me ntawm qhov 2. Qhov no txhais tau tias tus lej 1 muaj tus lej thib 2 (tsis tseem ceeb yog daim duab.)
Qhov txawv ntawm tus nqi thiab tus lej
Tus nqi cuam tshuam rau qhov ruaj khov ntawm 2 yam thaum qhov sib piv yog kev sib raug zoo ntawm ntau yam. Ib chav tsev tus nqi tuaj yeem sau tau li 12 kms ib teev lossis 10km / 1hr; ib qho piv txwv tuaj yeem sau ua qhov no 10: 1 lossis nyeem raws li 10 yog rau 1. Tus nqi feem ntau cuam tshuam rau qee qhov kev hloov pauv thaum qhov piv yog qhov sib txawv ntawm qee yam. Tus nqi feem ntau yog tsom rau physics thiab chemistry, feem ntau yog ntsuas, cov ntsiab lus xws li ntsuas qhov nrawm, lub plawv dhia, tus lej nyeem ntawv thiab, thiab lwm yam.thaum piv tau yog ib yam khoom, khoom, tub kawm ntawv los yog neeg.
Tus nqi thiab qhov sib piv yog qhov tseem ceeb hauv kev piav qhia qhov sib npaug ntawm ib qho thiab lwm qhov. Tus nqi tsis tuaj yeem yog ib qho yog tias tsis muaj qhov sib piv. Koj tseem tsis tau pom tias ob qho no tseem siv nyob rau hauv peb niaj hnub ua neej nyob xws li suav nyiaj paj hauv txhab nyiaj, tus nqi khoom thiab ntau ntxiv. Lub neej tau yooj yim dua vim ob leeg no.
In luv:
• Tus nqi yuav tsis muaj yog tias tsis muaj qhov sib piv.
• Tus nqi yog siv rau kev ntsuas
• Qhov piv yog siv rau lwm yam.
