txhawm rau ua tiav hauv kev ua lag luam niaj hnub no, cov tuam txhab lag luam yuav tsum siv tag nrho cov kev ntsuas txhawm rau nce kev sib tw. Cov yam tseem ceeb rau kev nce qhov ntsuas no yog: tus nqi txoj cai, assortment, qhov chaw ntawm qhov muag, qhov zoo ntawm cov khoom thiab cov kev pab cuam, scientific thiab technologies txoj kev loj hlob thiab cov khoom siv niaj hnub no, cov neeg ua haujlwm tsim nyog, thaj chaw faib khoom ntawm cov ntsiab lus muag hauv lub tebchaws thiab txawv teb chaws.. Txhawm rau kom ua tiav txoj cai tswj hwm tus nqi, lub tuam txhab yuav tsum tsis tu ncua xyuas nws cov nqi thiab txo lawv.
Tus nqi txo nqi
Yuav kom ua tiav qhov txo tus nqi ntawm kev tsim cov khoom, ntau cov xwm txheej yuav tsum tau ua tiav:
- nce productivity;
- txo qis kev siv zog;
- txo cov khoom siv;
- short marriage;
- qhia kev txuag nyiaj ntawm kev lag luam.
Ua ke, cov txheej txheem txiav nqi yuav pab ua lag luam nce cov txiaj ntsig thaum tswj hwm tib yam lossisnce ntau lawm.
Cia peb saib ze dua ntawm kev siv cov khoom siv, vim nws yog cov khoom ntawm cov nqi khoom siv uas feem ntau yog qhov tseem ceeb hauv cov qauv nqi. Yog tias qhov ntsuas tau nce ntxiv hauv qhov muaj zog, nws txhais tau tias cov khoom siv raw thiab cov khoom siv tsis zoo, thiab lub tuam txhab yuav tsum tau tshuaj xyuas thiab kho cov nqi ntawm cov khoom siv raw thiab cov khoom siv.
Material intensity
Qhov no yog qhov ntsuas ntawm cov khoom siv ntau npaum li cas los tsim ib chav tsev ntawm cov zis. Hauv lwm lo lus, dab tsi sib koom ua cov nqi khoom siv los ua ib feem ntawm cov nqi tsim khoom. Piv txwv li: kev lag luam uas muaj feem ntau ntawm cov nqi ntawm cov khoom siv raw thiab cov ntaub ntawv suav nrog hlau smelting, qab zib ntau lawm, mechanical engineering thiab lwm yam.
Cov qauv ntawm cov khoom siv suav nrog cov khoom siv yooj yim, pab cuam, nrog rau roj, lub zog thiab txo qis ntawm cov khoom muaj nqis ruaj khov.
Cov khoom siv yog qhov hloov pauv ntawm cov khoom siv tawm.
calculation formula
Khoom siv - qhov no yog daim duab uas muaj kev sib raug zoo nrog tus nqi ntawm cov khoom siv. Ntawd yog, ntau dua cov nqi ntawm cov khoom siv raw thiab cov khoom siv hauv cov txheej txheem ntawm kev tsim khoom, qhov ntau dua yuav yog cov khoom siv, cov qauv rau kev suav uas tau nthuav tawm hauv qab no:
Me=MZ / C, qhov twg
Me - khoom siv, MZ - tus nqi ntawm kev yuav khoom raw, C - tag nrho tus nqi ntawm cov khoom tiav.
hom khoom siv
Muaj ntau hom khoom siv. Cov no yog qhov tshwj xeeb, cov qauv thiab tsis meej. Cov khoom siv tshwj xeeb qhia txog qhov sib faib ntawm cov ntaub ntawv hauv ib qho ntawm cov khoom hauv lub cev. Tus qauv tsim pab kom paub seb qhov sib koom hauv cov ntsiab lus nyiaj txiag ib yam ntawm cov khoom siv raw khoom nyob hauv kev tsim khoom ntawm cov khoom. Tus nqi tiag tiag yuav tso cai rau tus thawj tswj xyuas kom paub txog tus nqi ntawm cov nqi peev txheej rau kev tsim khoom ntawm ib qho ntawm cov khoom, nrog rau nws qhov sib koom hauv qhov hnyav thiab qib ntawm cov nqi khoom muag. Nws yog xam los ntawm qhov sib piv ntawm qhov hnyav ntawm cov khoom mus rau tus nqi ntawm kev noj cov khoom siv raw hauv ib chav tsev ntawm kev tsim khoom. Cov khoom siv tshwj xeeb yog qhov suav ntawm cov khoom ntawm cov khoom siv raw thiab lawv qhov tshwj xeeb lub ntiajteb txawj nqus nyob rau hauv cov khoom muaj pes tsawg leeg.
Txoj hauv kev txhim kho
Ua ntej, nws txiav txim siab seb txoj kev npaj siv nyiaj puas phim cov nuj nqis tiag tiag. Qhov thib ob, lawv txiav txim siab npaum li cas lub koom haum xav tau cov peev txheej zoo li no. Thib peb, ntsuas qhov ua tau zoo ntawm kev siv cov khoom siv. Plaub, nrog kev pab los ntawm kev txheeb xyuas qhov tseem ceeb, nws pom tias cov peev txheej twg xav tau ntau dua thiab qhov twg yuav tsum tau txo qis kev siv cov peev txheej. Thib tsib, lawv suav cov nqi ntawm cov khoom siv thiab nws qhov cuam tshuam rau qhov ntim ntau lawm.
Raws li cov ntaub ntawv tau txais, cov lus xaus tau kos thiab kev txiav txim siab txog kev tswj hwm tsim nyog tau tsim los txhim kho lossis txo tus nqi.
