裂缝闭合 meaning in Chinese

closing up of cracks
crack closure

Based on estimating the type of filtration by constructed g and fraction , and determining the fracture closed point , the parameters such as the geometry of fracture , the leak - off coefficient can be calculated , and furthermore it can direct the acid fracturing design and improve the acid fracturing technology
通过构造g函数、函数可判断储层的滤失特性，确定裂缝闭合点从而得到裂缝的几何尺寸以及滤失系数等参数，进而指导酸压的施工设计和完善酸压工艺。
The results of the tests show clearly that the carrying capacity of shear - resistance and deformation property and ductility of the masonry walls were increased after being prestressed , and the prestressed walls are forced more uniform and material property can be completely developed . cracks are more slightness and more dense , and will be closed after being unloaded , and the walls will not fall apart with cracks , which indicate that such walls may retain the entirety well and have good resistance of collapse
试验表明施加预应力后，砌体墙的抗剪能力、变形能力和延性都有所提高，而且墙体受力均匀，材料性能发挥充分，卸荷后裂缝闭合，砌体墙“裂而不散” ，保持了较好的整体性，有良好的抗震、抗倒塌性能。
