次声武器
Infrasound
weapons
次声武器就是一种能发射频率低于20赫兹的次声波，使其与人体发生共振，致使共振的器官或部位发生位移、变形、甚至破裂，从而造成损伤以至死亡的高技术武器。
Infrasound
weapon is a kind of can launch less often than 20 hz device of the human body
in resonance, cause resonance organs or parts of displacement and deformation,
even happen ruptured, and the damage to the death of high-tech weapons.
次声武器具有隐蔽性强、传播速度快、传播距离远、穿透力强、不污染环境、不破坏设施等特点，是世界各国军方争相研制的非致命武器，并将成为未来战争中非常重要的新概念武器。
Infrasound weapons latent strong, speed,
dissemination of distance, strong penetration, no pollution, not destroy the
facilities, and other features, is the countries all over the world to military
developed non-lethal weapons, and will become the future war very important new
concept weapon.
次声波是频率为0.0001～20Hz的声波，这个频段通常是人耳听不到的。
Device is 0.0001 ~ 20 Hz frequency of sound waves,
the band is usually ear to hear.
由于人体各部位都存在细微而有节奏的脉动，这种脉动频率一般为2～16Hz，如内脏为4～6Hz，头部为8～12Hz等。
Due to the human body each place there are subtle
and rhythmic pulse, the pulse frequency for 2 ~ 16 Hz, such as the gut is 4 ~ 6
Hz, head for 8 to 12 Hz, etc.
人体的这些固有频率正好在次声波的频率范围内，一旦大功率的次声波作用于人体，就会引起人体强烈的共振，从而造成极大的伤害。
The natural frequency of the human body just in
the frequency of the device, within the scope of the high power once in the
human body function device, can cause human body strong resonance, so as to
cause great harm.
谈到共振的破坏力，可能不少读者都知道在19世纪的欧洲，曾多次发生过士兵齐步过桥引发桥体共振，使大桥倒塌的悲剧。
Talking about
the destructive force of the resonance, many readers may know that in Europe in the 19 th century, has repeatedly had soldiers
happy by crossing the bridge resonance of bridge, the tragedy of the bridge
collapsed.
坚固的大桥都可以毁于共振，何况血肉之躯呢！
Solid bridge can be destroyed by resonance, how
much more will flesh!
次声武器就是利用频率低于20Hz的次声波与人体发生共振，使共振的器官或部位发生位移和变形而造成人体损伤以至死亡的一种武器
Time is the use frequency sound weapon lower than
20 Hz device and the human body in resonance, make the resonance organ or parts
displacement and deformation happened caused damage to human body death of a
weapon
Device with human body resonance occur
the intensity and frequency of different, to the human body organs and areas of
the damage degree are different.
强度相同、频率不同的次声波可对不同器官和部位造成损伤；
The same intensity and frequency of
different device of different organs and parts can cause damage;
频率相同的次声波的杀伤程度视其波强度而定。
The same frequency device depending on
the degree of the killer wave intensity and calm.
次声波对人可产生精神的和机械的损伤。
People can produce device to the
spirit and mechanical damage.
其主要症状有：全身不适、无力、头晕目眩、恶心呕吐、眼球震颤，严重的可发生神志失常、癫狂不止、腹部疼痛、内脏破裂等。
The main symptoms have: the whole body
unwell, weakness, dizziness, nausea and vomiting, nystagmus, serious can happen
was wrong, madness, abdominal pain, more than internal organs burst, etc.
国外实验证明，10赫135分贝的次声波，可使小白鼠的内脏濒临坏死状态；
Overseas experiment prove, 10 Hector
135 db device, can make the mice on the internal organs of necrosis state;
0.5赫170分贝左右的次声波，可使狗的呼吸困难，甚至停止。
0.5 hz 170 decibels or so device, can
make the dog's breath is difficult, even stop.
次声是不易被人察觉和听不见的声音，在大气中传播衰减很少，与大气沟通的掩体和工事难以防御。
Time is not easy to sound be perceived
and hear the voice of the atmospheric attenuation spread very few, and the
atmosphere of the bunkers and works hard to communicate to the defense.
次声武器一般由次声发生器、动力装置和控制系统组成,其中次声发生器是关键。
Infrasound weapons general by
infrasound generator, power plant and control system composition, including
infrasound generator is the key.
次声武器的作用距离,决定于次声发生器的辐射声功率、指向性图案和声波的传播条件。
The role of infrasound weapons
distance, decided in times of sound generator radiated acoustic power,
directionality design and sound waves conditions.
次声波不易集聚成束，在空旷环境中很难产生高强次声。
Not the bundle concentration device,
in the open environment it is difficult to have a high strength infrasound.
次声的波长很长，要使它定向传播，其聚集系统的尺寸将会很大（直径达几十米或几百米），实际上很难实现。
Once the wavelength of the sound is
very long, will make it directional spread, the gathered the size of the system
will be large (diameter of dozens of meters or hundreds of meters), in fact it
is difficult to achieve.
因此，有的国家考虑采用两个频率相近的可听声波，使其频率差处在次声频率范围内，这样可较易实现次声的定向辐射。
Therefore, some countries consider to
use two frequencies similar to listen to sound waves, make its frequency
difference in infrasound frequency range, so can more easily to realize the
time of the directional sound radiation.
另外还有利用爆炸产生高强次声的次声弹的设想。
Another use high strength time from an
explosion of infrasound play the sound of ideas.
种类及应用
Types and application
从目前研制的情况看，次声武器的关键技术主要有两项，一项是高功率次声发生器，另一项是次声波的聚焦发射。
From the current situation of development view,
infrasound weapons are two of the main key technology, one is high power
infrasound generator, another device is the focus on launch.
关于聚焦技术国外报道很少，高功率发生器则有较多报道。
Focus on technology foreign coverage rarely, high
power generator is reported to have more.
按照感官刺激分类，次声武器可分为两种，即神经型和器官型。
Follow the sensory stimulation classification,
infrasound weapons can be divided into two kinds, namely nerves and organs
type.
神经型次声武器的发射频率与人脑的阿尔法节律相近(约5Hz)，能强烈刺激人的神经，使人晕眩头痛、精神沮丧或神经错乱。
Nerves infrasound weapons and frequency of the
human brain launch alpha rhythm close (about 5 Hz), can stimulate the human
strong nerve, make person dizzy headaches, mental depression or a neurological
disorder.
器官型次声武器的发射频率与人体内脏固有频率相当(4～8Hz)，可使人出现恶心呕吐、胃痛、呼吸困难等症状。
Type of weapons organs infrasound launch frequency
and human gut inherent frequency quite (4 to 8 Hz), can make the person nausea
vomiting, stomach, difficulty breathing and other symptoms.
以次声波产生的方式分类，次声武器大致可分为以下几种：
The way to produce device classification, infrasound
weapons can be roughly divided into the following kinds:
气爆式次声武器
Gas explosion type infrasound weapons
气爆式次声武器工作原理
Gas explosion type infrasound weapons work
principle
是将压缩空气、高压蒸汽或高压燃气有控制地以脉冲式突然放出，利用高速排出的气体激发周围媒质的低频振动，形成所需的次声波。
Is compressed air, high pressure steam or high
pressure gas with control to pulsed suddenly released, using high-speed the
expulsion of gas stimulate the medium low frequency vibration around, needed
for the formation of device.
这种次声装置因体积小、频率低、易控制，近年发展较快。
This time for small volume, acoustic device low
frequency and easy control, the fast development in recent years.
但其次声波强度较低，近距离使用才有效。
But the second sound waves strength is low, close
use was effective.
爆弹式次声武器
The explosion of infrasound weapons
是利用爆炸产生强次声波，也可称为次声弹。
Using explosions produce device is strong, can
also be called infrasound play.
爆炸所释放的能量约有50%形成冲击波，冲击波衰减后又产生次声波。
Bang the energy released about 50% form shock,
shock wave attenuation and produce device.
目前的新型次声弹是将已有的燃料空气弹加以改进，使原来只能形成一个云雾团变成可以形成若干云雾团，并能连续多次引爆。
The new times is the sound of the existing fuel
air play will be improved, and the original can only form a cloud group into
form a number cloud group, and has repeatedly and exploded.
只要控制好云雾团的数量和起爆时间间隔，就能获得所需频率的次声波。
As long as the control group and the bursting of
the cloud and mist the number of time intervals, can obtain frequency of the
device.
管式次声武器
Tubular infrasound weapons
其构造和工作原理很像乐器中的笛子，当管子中空气柱的振动与管子本身固有频率相同时，就可产生较强的次声波。
The structure and working principle of the Musical
Instruments like flute, when the pipe of vibration and tube column hollow
itself inherent frequency phase and at the same time, it can produce strong
device.
在管子一端装上一个活塞，用电动机驱动或用气流激励，当振动频率的1/4波长与管子长度相等时，可获得最强的次声波。
In the pipe end loaded on a piston, power motive
drive or with air incentives, as the vibration frequency and the pipe length is
equal to a quarter wavelength can be obtained when the strongest device.
但要产生次声波，管子必须足够长。
But to produce the device, the pipe must be long
enough.
扬声器式次声武器
The speaker type infrasound weapons
其工作原理与扬声器相似。
The working principle and the speaker similar.
采用特殊的振动膜片，膜片振动可产生一定频率的次声波。
The use of special vibration diaphragm, diaphragm
vibration can produce certain device of frequency.
但要产生一定强度的次声波，除要求较高的振幅外，还必须使振动膜面积足够大，其周长大致要与次声波波长相当。
But to produce a certain intensity of device, in
addition to demand higher amplitude outside, still must make vibration membrane
area is enough big, its circumference is generally a device with wavelength.
频率差拍式次声武器
Frequency difference of infrasound take weapons
是采用两个不同频率的声波发生器同时工作，利用它们频率的相差来获得需要的低频次声波。
Is to use two different frequency sound wave
generator working at the same time, use them to obtain the frequency is the
device to low frequency.
其中有一种方法是利用压电晶体产生两束频率稍有差异的超声波，两者作用产生高频和低频声波，高频声波是两者频率之和，低频声波是两者频率之差，高频声波在空气中很快衰减，低频声波(次声波)则直达目标。
One method is to use a piezoelectric crystal
produce two beams of slightly different frequency of ultrasonic, both effects
from high frequency and low frequency sound waves, high-frequency sound waves
is both the sum frequency, the low frequency sound waves are both frequency
difference, high-frequency sound waves in the air in the decay quickly, the low
frequency sound waves (device) is direct target.
这种方式能量转换率高，并可制成小型武器。
This way the energy conversion rate is high, and
can be made of small arms.

次声武器具有隐蔽性强，传播速度快、传播距离远，穿透力强，不污染环境和破坏设施等特点，军事科学家已把它列为未来战争中新概念武器的重要成员。
Infrasound weapons latent strong, speed,
dissemination of distance, strong penetration, no pollution and destruction
facilities and other characteristics, military scientists have to declare it in
the future war, new concepts important members of weapons.
它将成为新世纪战场上的新宠利器。
It will become the new century battlefield is new
bestow favor on tool.
缺点
faults
次声波武器虽是强大、厉害的武器，但却存在着固有的缺陷。
Though device is strong, severe weapons of
weapons, but has the inherent defect.
首先，次声波不易聚焦成束，实现定向聚焦发射相当困难，导致的直接结果就是敌我不分，容易误伤，且在空旷的环境中难于产生高强次声波；
First of all, is not easy to focus on the bundle
device, and realize the directional focus on launch is hard, cause the direct
result of all is against, easy to fire, and in the open environment difficult
to produce the high strength device;
其次，次声波很长，因而定向困难；
Second, the device is very long, thus directional
difficulties;
再次，它的聚焦尺寸太大，一般很难实现。
Again, it's focusing size is too big, generally
difficult to realize.
不管怎么说，次声武器的问世，世间又多了一种杀戮的方式。
Anyway, infrasound weapons coming out, and a new
world killing way.
由于次声武器对环境、自然生物及非战斗人员所产生的巨大的破坏作用，该武器是否应当投入实战值得商榷。
Due
to the environment, infrasound weapons natural biological and non-combatants
generated huge damage, the weapon whether we should be put into actual combat
is debatable.
