摘　　要：便携式火箭发射器中的火箭发动机所产生的初始脉冲冲击波和强噪声往往对人员产生很大伤害,以往这方面的研究不是非常充分,尤其是强噪声的发声机理、向发射筒前部的传播规律以及强噪声随时间的变化规律。文中通过试验和测试,得出所涉及发射噪声主要由三部分组成,其中三部分的规律各有不同。这些结论可为相关研究提供借鉴。The shock wave and strong noise which are produced by light rocket launcher.The shock wave and strong noise which are produced by light rocket launcher maybe have injure to the personnel.The study about the launch noise need to study deeper especially the vocalism mechanism of strong noise,the spread rule for the front of the launcher and the variational rule of strong noise along with the time.We find that the launch noise is made up of three parts through experiments and measurements.And they have different rules in every parts.These conclusions can provide reference for further study.
