Amagumbi abandayo angaphakathi zizinto eziphambili kwiivenkile ezinkulu, iplanti yokulungisa inyama, izixhobo ezibandayo, iindawo zokutyela, iihotele, kunye nayo nayiphi na enye indawo efuna ukugcina ukutya okutsha, okukhenkcezisiweyo okanye okupholiswe kwangaphambili, inyama kunye nentlanzi. Okanye ukuhlakulela imifuno yembewu, iziqhamo, intyatyambo, kunye nokugcina iziyobisi, isiselo njalo njalo.
Uncedo lweDong`a
amandla aphezulu, ubunzima obulula. Ubuninzi obuphantsi kunye namandla esivuno xa kuthelekiswa nekhonkrithi kunye neenkuni. Ngoko ke, phantsi kweemeko ezifanayo zoxinzelelo, amalungu esakhiwo sensimbi ancinci kwicandelo, alula ngobunzima, alula ukuthutha kunye nokufaka, kwaye afanelekile kwiindawo ezinkulu, eziphakamileyo kunye nezakhiwo ezinzima. I-2, intsimbi inokuqina okulungileyo kunye neplastiki, izinto ezifanayo, ukuthembeka okuphezulu kwesakhiwo, ilungele ukuthwala impembelelo kunye nomthwalo oguqukayo, inokusebenza kakuhle kwe-seismic. Ulwakhiwo lwangaphakathi lwentsimbi lufana kwaye lusondele kwi-isotropic ye-homogeneous body, kunye nokusebenza kwesakhiwo sensimbi kuhambelana ngokupheleleyo nethiyori yokubala, ngoko ukhuseleko kunye nokuthembeka kuphezulu.
Izibonelelo zizonke: Ukuthenga indawo enye kuvela eDong'an.
Inkampani yamaphepha okwakha i-Dong`an yinkampani enemveliso eneqela elizimeleyo le-R&D, ibonelela ngeyona mveliso inexabiso eliphantsi. Iinkonzo ezidityanisiweyo zobuchwephesha zoyilo, imveliso, kunye nezicwangciso zikwenza uzive ukhululekile.
Ukubuza kuthi ngayo nantoni na oyithandayo ngoku
