zero stress-optical constant

The X-ray stress constants of five crystalline planes of beryllium were measured by using a cantilever beam loading method on X2001 stress analyzer.

在X2001应力分析仪上采用悬臂梁加载法测试了可以用于铍的X射线应力测试的5个衍射晶面的应力常数。

By using Co Kαand Fe Kαirradiations,the X-ray stress constants of tungsten alloys were determined with X-ray diffraction method.

用ＣｏＫα和ＦｅＫαＸ射线，分别标定了试样的（２２２）和（３１０）两组晶面的应力常数值，并探讨了钨含量和加工状态对应力常数的影响。

In this paper the load was inflicted on the demarcation board by the self-made stress constant demarca- tion installment,the two receives the probe head s sound time difference change that was arose by the load change was menstruated.

利用应力常数标定系统对待标定试样施加载荷,测定两接收探头由于载荷变化引起的声时差变化,从而确定出材料的应力常数。
