本文认为，输出光束的漂移主要是器件不稳定热传导引起毛细管摆动所致。

This paper suggests that the main cause of the beam drift of laser output is capillary sway due to unstable thermal conduction.

从弹箭空间摆动和弹性振动耦合的动力学模型出发，对弹箭飞行过程中的共振不稳定性问题进行了研究。

Based on the coupled dynamic model for the spatial rotation and elastic vibration of a body, the resonance unstability of projectiles in flight is studied in the paper.
