1. In order to make clear explanation, the basic concepts and main procedures of the R6 method proposed by CEGB are described, and an example of assessments of a pressure vessel by different methods is given.

为了阐明这一问题,在文中首先简要介绍R6方法,再通过用R6方法和单纯用K因子方法计算某一压力容器缺陷的对比实例说明后者的不足。

2. In general the failures of pressure vessels are dominated by e lasto-plastic parameter named as J -integral. The J -integral parameter was adopted by many codes such as CEGB R6, PD6493 and SAPV95 to assess the str uctures safe ty.

压力容器的失效大多为弹塑性断裂失效 ,CEGBR6、PD64 93、SAPV95等规范都采用J积分参量进行断裂评价。

3. A Research on the Reliability Method of the Pressure Vessels and Piping Defect Analysis Based on CEGB R6

压力容器缺陷评定的可靠性方法研究

4. The probabilistic safety assessment technology based on R6 method was reviewed in this paper. The current development of CEGB R6 was also introduced. Then, two methods for probabilistic safety assessment were presented.

回顾了基于R6方法的概率安全评定技术，介绍了CEGBR6的最新进展，给出了两种概率安全评定的方法。

5. Based on summaries of international standards and research results for flawed pipe safety assessment, a flawed pipe safety assessment procedure combining API1104 acceptance criteria with CEGB R6 Evaluation Procedure is introduced.

在简要评述国际压力管道缺陷安全评定规范的基础上 ,制定了采用API1 1 0 4经验性验收准则与CEGBR6标准评定方法相结合的压力管道安全评定的技术路线。

6. Based on assessment and analysis of CEGB Report R/H/R_6.Rev.

本文在对英国CEGB R/H/R6-R ev.

7. At the some time the general failure assessment curve of CEGB R/H/R6 (Rev. 3) may apllied to defect assessment of vessels nozzle high strain region.

研究表明各种椭圆孔、各种裂纹尺寸、各种载荷条件下的失效评定曲线是有很窄的分散带,同时现有的通用失效评定曲线可以适用于压力容器接管高应变区内缺陷的安全评定。
