displacement constant meaning in Chinese
位移常数
Examples
- It was found that many dislocations were emitted from the crack tip during the early stage of crack propagation and were driven out of the crack tip area , and them piled up inversely . a closed dislocation free zone ( dfz ) was formed between the crack tip and the pile - up dislocations . keeping displacement constant , the dislocations were still emitted from the crack tip for a while
本文首先系统地研究了工业纯金属( fe ， al ， ti和mg )断裂的微观过程，发现所研究的工业纯金属断裂过程裂尖均首先发射位错，并离开裂尖向前运动、在裂尖留下无位错区，位错反塞积在五位错区的端部，反塞积位错群一般呈封闭状包围无位错区。 - Keeping displacement constant , the length of dfz decreased . the less the lattice resistance is , the longer the dfz is . during the crack propagation , the pile - up dislocations may move forward in the previous direction or in another direction which caused shape of dfz changed . the dislocations emitted from the crack tip might pile up in the dfz and can be served as dislocation source in the successive loading
在裂纹扩展过程，反塞积位错群发生变化，可以沿原来方向继续向前运动，也可能改变运动方向使无位错区的形状发生变化，后来发射出的位错可以在原五位错区中塞积，并可作为位错源在后续的加载中发射位错。
