Los ntawm daim ntawv thov txheej, cov xim pleev xim ua kom muaj zog, txuas ntxiv txheej rau saum npoo ntawm cov khoom, yog li ua tiav nws cov hniav zoo nkauj, tiv thaiv, thiab lwm yam haujlwm tshwj xeeb.
Cov ntsiab lus tseem ceeb ntawm txheej txheej engineering yog: txheej txheej txheej txheej thiab cov khoom siv, txheej txheej, ib puag ncig ua haujlwm, thiab kev tswj txheej txheej.
Qhov zoo ntawm cov ntaub ntawv uas tau coated yog qhov tseem ceeb rau kev tau txais cov txheej txheem. Cov txheej txheem txheej txheej, khoom siv, thiab ib puag ncig ua haujlwm yog qhov tsim nyog rau kev siv tag nrho cov khoom siv txheej txheej, tau txais cov txheej txheem zoo, txo cov nqi tsim khoom, thiab txhim kho kev lag luam. Kev tswj txheej txheej yog qhov tseem ceeb rau kev ua kom muaj kev ua tiav ntawm cov txheej txheem tsim, ua kom cov txheej txheem ruaj khov, thiab ua tiav cov hom phiaj txheej xav tau thiab cov txiaj ntsig kev lag luam.
