二次调质后，堆芯段筒体锻件产生了椭圆变形，为了不影响锻件已有性能，采用冷校形加去应力回火方法进行校正。

In order to keep the property of forging pieces which they already have, calibrating in the way of cold correcting the shape with stress release and tempering could get a better result.

首先，对两端加锚后裂纹尖端的应力场做了一些相应研究，对两端加锚的模型破坏模式做了简短的介绍，为以后的工作提出了建议。

First of all, the study on the crack tip stress field under the model anchored by CFRP have been done, and then do a brief introduction about the failure mode of the model with the CFRP.
