- 摘要:
- 任何压力容器和结构构件中实际上都存在着数量不等的裂纹缺陷，本文以控制裂纹缺陷的容许限度为目的，在确保安全使用的前提下，以裂纹容限理论为基础，结合工程应用进行定性与定量的解析探讨，为工程实践提供具有实用性的理论依据。
In fact，there should be more or less some flaws or failures in the pressure vessel and thestructure. Under a purpose of control allowable limit of flaws and prerequisite of ensuring of safe use this paper，based on theory of allowable limit of flaw，gives qualitative and quantitative analy-sis in accordance with engineering application and provides theoretical basis for engineering prac-ticn1997,3(3): 1-5 收稿日期：1996-12-25
