为解决微光瞄准镜零位移走动量问题，给出了瞄准镜分划板调节结构。
For solving the zero displacement movement problem of low-level-light (LLL) sight device, the regulating structure of LLL sight device reticle was given.
我发现左镜筒的鬼影比右镜筒厉害一些(怪了，右镜筒才有分划板呀)。
I have seen the intensity of ghosting being a bit higher through the left barrel than through the right (as a surprise, since the reticle is placed in right barrel).
本文总结了过去天象仪上所用各种分划板的加工工艺的主要缺点，提出了新的加工方法。
Main disadvantages of the technology of making various graticules used for planetarium are summarized. A new method is given.
