LBB

With the more and more stringent safety requirements for high pressure vessels and nuclear energy equipment , the importance of LBB rule is increasing .

随着人们对高压容器特别是核能设备安全性要求的提高，先漏后爆准则的重要性不断增加。

Leak before break ( LBB ) is an important concept for assessing pressure vessels and nuclear equipment .

破前漏（简称LBB）是压力容器、核电站设备结构设计与评价中的一个重要准则。

The affection of fatigue and creep to the crack growth must be considered when LBB is applied on the nuclear pipes in the high temperature reactors ( as fast reactor ) beyond the creep temperature .

对于在蠕变温度以上高温堆（如快堆）的核级管道，运用LBB分析时应该考虑疲劳和蠕变对裂纹扩展的影响。

The LBB assessment criterion is a simple , reliable and economical method , in which the labor - ous fracture assessment is reduced to the failure assessment diagram for technicians in terms of various failure theories .

它根据不同的失效理论，将复杂的断裂力学评定方法简化成失效评定图供技术人员使用。

For newer entrants , " to reach the level of brand awareness in China of a Chanel or a Louis Vuitton is going to take years , " says Aude Bousser , founder of LBB Asia , a luxury brand consultancy .

对于新入行者，“要在中国达到像香奈儿或者路易威登（LouisVuitton）那样的品牌知名度需要许多年，”奢侈品牌咨询机构LBBAsia的创始人奥德•布塞（AudeBousser）说。

It is demonstrated that the pipe meets the conditions that the crack is stable and the leakage is detectible which LBB asks for , and it also satisfies the time request from the beginning of leak to the moment at which the crack is unstable .

经过验证得到：选用的管道符合LBB技术对于裂纹稳定性以及泄漏量可探测性的条件，满足从开始泄漏到裂纹失稳的时间要求。
