The mechanical property of N80 steel has increased obviously after adding corrosion inhibitor, where the ductility of N80 steel increased, and crack fissure of fracture surface decrease.
添加緩蝕劑后使N80試樣的韌性有明顯的增加，斷口裂紋縫隙明顯減小，力學(xué)性能有了明顯的提高。
Hitherto, unstable rock is the weakest one to study in disasters, specially damage and fracture of control fissure under loads is one key technique in study of develop mechanism of unstable rock.
危巖是迄今研究程度極其薄弱的地質(zhì)災(zāi)害類型，而主控結(jié)構(gòu)面受荷損傷斷裂擴(kuò)展過(guò)程是危巖發(fā)育機(jī)理研究的核心技術(shù)。
