lbb的翻译

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。

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。

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。
