In this paper, a new method of indexing higher order laue pattern (HOLP) has been advanced by changing some higher order laue spots to zero order, and it is pointed out that the 180′ indefinitive of zero order laue index can be eliminated by this method.
提出了一种使高阶劳埃斑（ＨＯＬＰ）零阶化来标定其指数的原理与方法，同时指出可以用该法来消除零阶劳埃斑指数的１８０°不唯一性。
The principle and design process of the system to measure the roundness error using the Lloyd mirror, linear CCD image processing system are described.
论述了系统利用劳埃德镜干涉装置 ,通过线阵CCD图像处理系统自动测量圆度误差的工作原理及过程设计。
In this paper, it is pointed out and demonstrated that the solution of Darwin transfer equation got in 1995 for slab crystal struck by δ incident beam in Laue case, is not only valid in slab crystal, but also in a more general case, in the case that the formed parallelogram is still in the region of crystal.
本文将Ｄａｒｗｉｎ方程在δ束入射平板晶体劳埃几何中的解析解推广到了一般形状晶体中，并给出了物理解释及数学证
