Pwm ceevyog ib qho cuab yeej siv los tsim cov khoom uas muaj qhov loj me, cov duab thiab qhov tseeb ntawm qhov chaw.Nws yog tsuas yog siv nyob rau hauv loj ntau lawm.Txawm hais tias cov khoom tsim thiab cov nqi ntawm cov pwm ceev yog qhov siab, vim tias nws yog cov khoom tsim tawm, nyob rau hauv txoj kev no, tus nqi ntawm txhua yam khoom tau raug txo ntau heev.Hnub no, kuv yuav muab cov lus qhia tshwj xeeb rau koj vim li cas koj thiaj li xav ua pwm sai.
Qhov laj thawj yog vim li cas tib neeg ua cov pwm nrawm yog vim muaj peev xwm los kuaj thiab txheeb xyuas qhov chaw hauv cov qauv kev txhim kho theem ntawm kev tsim khoom tshiab.Txawm hais tias muaj ntau lwm cov txheej txheem uas tuaj yeem ua tiav sai dua thiab pheej yig dua cov qauv, qhov zoo ntawm cov pwm nrawm feem ntau nyob hauv cov ntaub ntawv thiab cov txheej txheem.
Cov cuab yeej ceev ceev tuaj yeem siv cov ntaub ntawv qib tsim khoom tiag tiag, tso cai rau cov neeg siv kom nkag siab meej tias cov khoom no puas tuaj yeem ua tau raws li cov qauv hauv cov txheej txheem tsim khoom tiag tiag, kom lawv tuaj yeem txiav txim siab seb cov khoom siv tau raug xaiv.Cov khoom tseem yog txhaj molded, uas tuaj yeem siv rau kev tsim khoom, yog li covpwm ceevkuj tuaj yeem siv rau kev cuam tshuam thiab kev ntsuas kev ntxhov siab, thiab kev hloov pauv tuaj yeem ua tau.
Tib neeg kuj siv cov pwm nrawm los kuaj cov khoom tsis zoo, txhawm rau xyuas kom meej tias cov khoom ntim tau raug thiab ua haujlwm raws li qhov xav tau.Ua li no, cov neeg tsim qauv tuaj yeem ntes ntau cov txheej txheem tsis xws luag thiab rov tsim dua lossis siv lwm yam kev ntsuas los tiv thaiv teeb meem.
Pwm ceev, tseem hu ua mos pwm, yog ib hom kev txhaj tshuaj pwm, uas tuaj yeem tau txais ntau qhov chaw sai thiab pheej yig.Nws yog ceev thiab kev lag luam, thiab tuaj yeem tshawb xyuas thiab ntsuas qhov chaw ua ntej tsim pwm.Thaum cov khoom R & D project yog 90% tseeb, cov cuab yeej ceev yuav raug xaiv
