摘　　要：探讨了分光计中对望远镜进行各步调节的原理,解释望远镜聚焦无穷远、望远镜光轴垂直于仪器转轴及分划板竖直准线平行于仪器转轴的调节原理,并建议在分划板竖直准线上平均划分出尽可能小的刻度,以便减少对光轴的调节次数。The adjusting principles of the telescope in the spectrometer are discussed in the article, and the adjusting principle of the regulating of telescopes to focus infinity is discussed,and how to adjust the optical axis of telescope perpendicular to the rotating shaft is also explained in the text. The article also tells us how to adjust the vertical direetrix of the partition board to parallel to the rotating shaft of instruments. In order to reduce the times of adjusting on the optical axis, the scale of the vertical directrix of the partition board is suggested as small as possible.
