Lub sijhawm yog nce qib. Nyob rau hauv xws li ib puag ncig loj, ntau lub hnab ntim khoom tau sprung li. Rau qee qhov tshwm sim, Khoom noj ntim cov hnab ntim khoom yuav tsum ntsib ntau lub sijhawm thiab ntau cov nyom. Vim li no, thaum xaiv cov chaw tsim khoom lag luam ntim cov khoom ntim khoom noj, koj yuav tsum ua txoj haujlwm ntawm kev tshawb fawb.
1. Kev txiav txim tsawg ntawm cov hnab ntim nqus tsev: Mekas raws li cov neeg siv khoom yuav tsum tau, ua kom muaj nuj nqis loj ntawm cov chaw tsim khoom.
2. Qhov sib piv ntawm lub hnab ntim nqus tsev
3. Lub hnab ntim tshuab nqus tsev yog kuab paug {{1} pub dawb: Tsis muaj cov nplaum ntxiv, tsis muaj kev muaj kuab paug, ntsuab thiab ua ib puag ncig.
4. Lub hnab ntim nqus muaj ntau cov ntawv thov: Lub hnab nqus tsev yog tsim nyog rau kev lag luam uas yuav tsum tau nqus ntim, xws li cov ntawv, khoom siv hluav taws xob, tshuaj ntsuab, thiab optoelectronics.
