propagation of crack meaning in Chinese
裂纹的扩展
Examples
- ( 4 ) the relationship between electric emission pluse and the propagation of cracks in concrete under quasi - static loading is exhibited
( 4 )揭示了混凝土在准静载下裂纹扩展与电发射脉冲之间的关系。 - This concentration of stress further accelerates cartilage wear with thinning of outer layers and propagation of cracks and fissures in the deeper layers
集中的应有尽有力进一步加速外民支软骨磨损及变薄,也加速深层碎裂和裂隙的扩布。 - It is shown that the first resonant frequency and the first anti - resonant frequency decrease synchronously due to the propagation of crack
从该曲线可以发现,梁的第一阶谐振频率和反谐振频率都随裂纹的出现而减小,并且频率减少量随裂纹尺寸的增大而增加。 - The results show that the thermal fatigue cracks after forming propagate preferentially in the hard phase , and the propagation of crack is stoped and dulled when it meet steel basic phase
结果表明:萌生后的热疲劳裂纹优先在硬质相中扩展,遇到钢基体相后受阻、钝化。 - ( 3 ) the methods of detecting sub - critical propagation of cracks in concrete dams are explored by use of grey system theory , motion stability theory and catastrophe theory , and three criteria for sub - critical crack propagation are given
( 3 )采用灰色系统理论、运动稳定性理论和突变理论,研究了混凝土坝裂缝亚临界扩展识别方法,给出了三个裂缝亚临界扩展判据。
