摘　　要：在X2 0 0 1应力分析仪上采用悬臂梁加载法测试用于铍X射线应力测试的五个衍射晶面的应力常数。结果表明 ,铍的五个衍射晶面的应力常数差异较大 ,在进行X射线应力分析时 ,采用相应衍射晶面的应力常数 ,才能获得准确的应力分析结果。由于X射线对铍有较大的穿透深度 。The stress constants of the five crystalline planes of beryllium are measured by using cantilever beam loading method on X2001 stress analytical instrument. The results show that the stress constant of each plane is different from the others,so the stress constant corresponding to the diffraction plane must be adopted to acquire the exact stress value on X-ray stress analysis.For the penetration depth of X-ray in beryllium is large,the effect of penetration depth on stress constant measuring must be considered.
