通过对梨晶顶面稍斜的角度能看到这些生长纹，如图2所示。
These lines are seen by looking at a slightly oblique angle towards the top surface of the boule, as shown in Figure 2.
结果表明：弹性垫圈断口为典型的沿晶断裂，在断裂的晶面上有细小的爪状纹和微孔。此为高强度钢氢脆断口的特征。
The result shows that it was the typical intergranular fracture, and there were scrappy claw and tiny pore in the fracture of crystal face.
