The results show that the X-ray stress constant of each plane in beryllium is different, so the X-ray stress constant corresponding to a diffraction plane must be adopted in order to acquire the exact stress value on X-ray stress analysis.

• 结果表明,铍的5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,应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。
