fissure fracture

基本解释

As the strata thickness increases the open angle of the starting fracture-fissure decreases.
随岩层厚度增大，起裂时岩层破断裂缝的张开角度减小；

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.
添加缓蚀剂后使N80试样的韧性有明显的增加，断口裂纹缝隙明显减小，力学性能有了明显的提高。
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.
危岩是迄今研究程度极其薄弱的地质灾害类型，而主控结构面受荷损伤断裂扩展过程是危岩发育机理研究的核心技术。
