失效的

This text passes correctly elm two of Daqing oil field is united --One Song unite person who bury oil pipeline scene to live in environment survey and study, is it take a sample test , environmental corrosivity survey , corrosivity measuring of pipeline and assess of soil to excavate, is it cause person who bury pipeline antiseptic layers of invalid main factor to find out , confirm the environmental grade of corrosion of soil according to environmental comprehensive physics and chemistry index of soil, grasp pipeline antiseptic invalid law of layer , study antiseptic layers of resistivity decay law and to influence that negative pole protect, is it suitable for person who bury antiseptic layer of life-span of the pipeline calculate formulae and actual effect criterion model to propose on the basis of this text, illustrate and simply analyse oil field long to fail person who bury antiseptic layer of surplus ability to work of the pipeline, unite for elm two --One Song unite pipeline antiseptic maintenance of layer , is it put forward science rational suggestion to change.

本文通过对大庆油田榆二联——宋一联埋地输油管道所处环境的现场调研、开挖取样化验、环境土壤的腐蚀性勘测、管线的腐蚀性检测和评估，找出引起埋地管道防腐层失效的主要因素，并根据环境土壤的综合理化指标确定该段环境土壤的腐蚀等级，掌握管道防腐层的失效规律，研究防腐层电阻率衰减规律及其对阴极保护的影响，在本文的基础上提出适用于埋地管道防腐层寿命计算公式和失效判据模型，例证和浅析油田长输埋地管道防腐层剩余工作能力，为榆二联——宋一联管道防腐层的维修、更换提出科学合理的建议。

For the composites with a low content of TiC particle, the rupture manner was mainly the nucleation of cavity and following ductility splitting fracture. But for the composites with a high content of TiC particle, the cracking and decohesion of TiC particles were the main rupture mechanism. For the composite containing a middle TiC content, the rupture mechanism consisted of the above two styles, but the former was the dominating mechanism and the later was the subordinate mechanism.

对TiC体积分数较低的钢基复合材料，拉伸过程中TiC颗粒界面上的孔洞形核及随后塑性撕开机制是其断裂失效的主要机制；对TiC体积分数较高的钢基复合材料，拉伸过程中TiC颗粒的开裂及脱落是其断裂失效的主要机制：对TiC体积分数介于上述两者之间的钢基复合材料，拉伸过程中TiC颗粒界面上的孔洞形核及随后塑性撕开机制在其断裂失效过程中占主要地位，而TiC颗粒的开裂及脱落占次要地位。

Main reasons of causing drill collar screw failure are discovered by way of further investigation and analysis on these problems.
