1.This paper discusses the principle of inspection of sight lines deviation and its formation caus- es. A new method that laser beam replaces the bore axis and sensor measure gun sight lines deviation is presented, and its precision analyse is done, some inspection improvement measures are expound.
2.Aim and Methods Three methods are analysed and compared for measuring the lateral deflection of gun bore axis from firing plane and the deviation of the sight line from the barrel axis, according to the results measured in practice.
3.I, who was not the least put out by the sight of the dressing-room of a kept woman, spent some time agreeably inspecting its contents, neglecting none of them, and I noticed that all these magnificently wrought implements bore different initials and all manner of coronets.
