Cov Ntawv Thov
Raws li 3679 hlau yog siv nyob rau hauv ntau cov ntawv thov, suav nrog:
- Kev tsa tsev: Lub tsev qauv qauv, txuas hniav, thiab vaj tse.
- Engineering: Tshuab, khoom siv, thiab kev tsim khoom.
- Kev mus: Cov ciav hlau cov tsheb ciav hlau, cov khoom siv tsheb, thiab lwm yam kev lag luam ntsig txog kev thauj khoom.
Qhov sib txawv ntawm qib
Qeb 300: General-hom phiaj txheej txheem hlau nrog tsawg kawg vim cov txiaj ntsig zoo ntawm 300 MPa.
Qib 3 0 0l0: Suav nrog cov kev cuam tshuam kub-kub cuam tshuam kev ntsuam xyuas ntawm 0 degree, ua rau nws haum rau cov huab cua txias.
Qeb 300L15: Suav nrog cov kev cuam tshuam kub tsawg tiv thaiv kev ntsuam xyuas ntawm -15 degree, muab kev txhim kho nruj me ntsis hauv ib puag ncig txias heev.
Qib 3 0} 0s0: Tsim rau cov ntawv thov seismic, kom ua tau zoo dua hauv av qeeg-infone.
Kev xaiv yog nyob ntawmCov Kev Xav Siv War Cruam, ib puag ncig, thiab cov kev yuav tsum tau uaCov. Raws li 3679 muab ntau yam qauv qauv qauv kom haum ntau yam engineering.
