Rifle is a general term for individual shoulder fired long barrel firearms. This type of weapon is mainly used to launch bullets and kill exposed living targets. The effective range is usually 400-1000 meters; Bayonets can also be added, or the butt of a gun can be used for fighting; It is even equipped with grenade launcher to launch gun grenades, so as to achieve the purpose of point and surface killing and anti armor. It is the basic weapon and equipment of Modern Infantry.
According to the degree of automation, it is divided into non automatic rifle and automatic rifle. Non automatic rifles manually complete the firing actions such as ammunition feeding, locking, firing, unlocking and shelling. Generally, manual handle gun, needle firing mechanism and single firing mechanism are adopted, such as the 1944 7.62mm cavalry gun of the Soviet Union and the 6.5mm 38 rifle of Japan. According to the ammunition supply mode, non automatic rifles can be divided into single shot loading rifles and magazine rifles.
Mushroom cloud refers to the powerful explosion cloud generated by explosion. Its shape is similar to mushroom, with large top and small bottom, hence its name. There may be smoke, flames and sundries in the cloud. In modern times, it generally refers to the cloud formed after the explosion of nuclear weapons such as atomic bomb or hydrogen bomb. Volcanic eruptions or celestial impacts may also produce natural mushroom clouds.
A rising cloud of smoke formed when the fireball went out. The reflection and negative suction of the shock wave on the ground near the projection point of the explosion center make the ground lift a huge dust column, and the rising dust column connects with the smoke cloud to form a tall mushroom smoke cloud.
The mushroom cloud suddenly appears a lot of low-pressure hot gas near the ground. The hot air rises rapidly, causing a vortex turning outward and downward, which is called “smoke cloud”. At the same time, the vacuum state makes the smoke and sundries turn upward from the center to form a “dust column” (mushroom stem). A large amount of gas finally reaches the height of the same pressure as the surrounding air, and the rolled up sundries disperse and drift down.
Skull and Crossbones: Skull (sometimes with crossed bones) symbolize not only death, but also immortality and rebirth, because bones do not decompose after death, which is why many cemetery gates, paintings and icons in Europe use this mark.
Many people think that Skull and Crossbones are the common symbols of pirates, but this is not the case. There is no universal logo for pirates. The common Skull logo is only adopted by the famous pirate Edward England in history. The well-known Skull and Crossbones logo is the result of its popularization by Robert Louis Stevenson, the author of treasure island.
The Kitsune is regarded as the God of rice and lotus in Japan. It is the messenger between human beings and God. It has the custom of divining abundance and ferocity. Wearing a Kitsune mask is the hope to have this power.
Kitsune mask has become one of the hidden Japanese and wind cultures. You can see the shadow of Kitsune mask in all kinds of daymans, such as firefly forest, summer friend account and other animation involving shrines and monsters.
Japan’s Kitsune mask is a mask used in Neng Le or Shenle, and later gradually transformed into a traditional Japanese toy. Kitsune noodles can be divided into many kinds, of which the most common are “sky Kitsune” and “white Kitsune”.
Fox is the general name of this kind of animals among the people. It has a wide variety, including arctic fox, red fox, Silver Black Fox, sand fox, etc. Smart and timid, it often appears as “fox spirit” in ancient myths. Although it was also used as a totem in ancient times, it never appeared in formal sacrifice. It is mostly associated with cunning and sneakiness because of its “indecent image”. Over the years, the fox demon and fox fairy have formed a unique goblin culture in various novels and anecdotes.
The character of fox was totem and auspicious beast at first, and then monster and goblin. Even when it was regarded as fox God and fox fairy, it was still goblin. Fox gods and fox immortals have never been included in the sacrificial ceremony, and have always been within the scope of sexual worship, just because of the indecency of fox gods and fox immortals. Therefore, the early stage of fox culture is totem culture and Furui culture, the later stage is goblin culture, and goblin culture is the main aspect.
As a goblin, the fox demon is an unparalleled role in the huge goblin group, which can be called the most goblin. After entering the aesthetic culture from religious folk culture, the fox demon has experienced a new value judgment and aesthetic transformation, and has become the most charming aesthetic image. The fox we see is completely different from that in the novel.
