求翻译：在这篇文章中，首先针对含裂纹管道性能评定方法方法进行了选择。在此基础上，利用有限元软件Abaqus建立有限元模型并且分别详细分析了管道长度、裂纹分布以及裂纹深度对含裂纹管道影响，通过对不同参数模型的对比，得出管道长度、裂纹分布以及裂纹深度对管道应力分布的影响，掌握裂纹尖端发展过程的规律。是什么意思？

In this article, the first choice for the cracked pipe performance assessment methods. On this basis, the use of finite element software abaqus finite element model and detailed analysis of the impact of pipeline length, the crack distribution and crack depth on the pipeline with cracks, through the

In this article, first at a crack pipe performance measurement methods Methods for the selection. On this basis, and use a finite element software Abaqus finite element models, and detailed analysis of the length of tubing, cracks crack depth distribution, as well as with cracks in the pipe, to the

In this article, first aimed at including the crack pipeline performance evaluation method method has carried on the choice.And in this foundation, distinguished the multianalysis pipeline length, the crack distribution as well as the crack depth using the finite element software Abaqus establishmen

In this article, first performance evaluation method for cracked pipes were selected. On this basis, finite element model and using Abaqus finite element software separately detailed analysis on pipe crack depth, crack length distribution and effects on the cracked pipe, through the comparison of di
