1. Simulation System Design For Single Rod Tracking and Laser Range Finding Based on Sighting Telescope Visual Field
基于瞄准镜视景的单柄跟踪激光测距仿真系统设计
2. Some levels have a micrometer screw which permits tilting the telescope with its attached level tube and thus permits centering the bubble while sighting at the rod.
一些有水平尺螺丝允许倾斜望远镜其重视程度，从而许可证管中心发现泡沫在棒。
