If they have the X-ray powder diffraction patternsof materials, even if being non-expert on X-ray crystal structure, they can conveniently get the indexofdiffraction lines and cell parameters.
对于非专业X 射线晶体结构人员，只要得到材料衍射图谱后，能很方便计算点阵常数和衍射线指标化。

In general, the half width of X-ray diffraction is used as a strength indexof material surface.
通常用X射线衍射线的半高宽作为材料表面的强度指标。

As their applications we have studied the effect of air index gradient on laser alignment and the additional diffraction loss of laser caused by inhomogeneous pump.
