Infrasound Wave

The infrasound wave and the infrasound weapon have been aroused people 's attention and research since last century end , so infrasound emission and focus technology are in the initial step , and there are many puzzles of theory and technology are need to be solved .

次声波和次声武器从上世纪末才开始引起人们的关注和研究，因此次声发射和聚焦技术还处于起步阶段，许多理论和技术难题需要解决。

The vibration of the machines , automobiles , and infrasound wave , etc. can lead to physiological function change and even pathological injury to human when it reaches some intensity .

一定强度的机械作业振动、汽车振动、声波特别是次声波振动等都会对人体造成生理功能改变，甚至病理性损伤。

In this paper , it is analyzed that mechanism of conventional missile explosion produces sound wave , conclude that infrasound wave is transformed from sound wave of conventional missile warhead explosion .

根据靶场试验的实测数据的计算结果，分析了常规弹头爆炸产生声波的机理，从而得出了常规弹头爆炸时冲击波衰减后产生次声波。

The infrasound wave is a wave that frequency is between 10-6 ~ 20 Hz , and has abroad application foreground . The signal of the frequency can not be directly transmitted passing antenna .

次声波是频率在10-6~20Hz的波，在生物医学、气象学、军事等领域有着广泛应用前景，此频段的信号无法通过天线直接发射。

At present time , the infrasound method stays the stage of using recorders to record the infrasound wave continuously for 24 hours . Automatically data acquisition and computerized analysis is not available .

目前次声波采用记录仪连续24小时观测记录其波形，还未实现数据的自动采集，所以无法利用计算机对信号进行分析处理。
