Crossbows are the sharp weapons of ancient times. The crossbows are divided into two-arrow crossbows and one-arrow crossbows.
One-arrow crossbows are mainly used in fine strikes. On the battlefield of ancient times, in confrontations, soldiers want to take the head of the enemy general, or in the midst of chaos, they can accurately shoot key people, and one arrow crossbow will show their ability. Its arrows can also concentrate their energy, aim well, and hit the key with one arrow. For example, in the Han Dynasty, Li Guang made good use of crossbows and arrows to fight outside the Great Wall. He tried to shoot and kill the enemy's scouts at a distance, so that the enemy's movements are clear, and it is very beneficial for marching. Furthermore, when hunting, the one-arrow crossbow can target a single prey, avoid disturbing the group of beasts, improve the accuracy of hunting, and obtain fresh meat for consumption or exchange for other things.
Two-arrow crossbows need to be quick-fired and suppressed. In ancient times, although the next-arrow crossbow in the city can accurately kill the enemy, the efficiency is slightly inferior. The two-arrow crossbow can shoot two arrows in a short time, forming a rain of arrows of a certain density, which can suppress the defending enemy in the city. Make the enemy unable to calmly shoot arrows and throw stones, creating conditions for their own siege. And in the field, when the enemy is crowded, the two-arrow crossbow can be fired quickly, forming a deterrent in a certain area, delaying the enemy's attack, and gaining time for the enemy to rectify their positions and adjust their tactics. In the jungle and other places, when encountering ambushes, the rapid fire of the two-arrow crossbow can instantly shoot arrows around, disperse or repel the invading enemy, and ensure their own safety.
From this perspective, the one-arrow crossbow is more accurate, and the two-arrow crossbow is more efficient and suppressive. At different times and in different situations, both are good tools for defeating the enemy, defending the country, and maintaining their livelihood.

In the past, if you want to combine the two, one of the ways is to refine the first and make the first. With the crucible, put it in the middle, and the drum will make its fire. When the liquid is melted, it is made in a special way. The system of the standard is refined into the microscopic, and the shape of the engraved two or one is engraved on it. The liquid is poured into the standard, and the cold water is poured, so that two or one billets can be obtained. The quality, with the equipment of grinding, trims the quality of the billet, makes it flat and smooth, removes its defects and burrs, and the finished product is finished.
There is another method, in terms of metallurgy, first determine the dosage. With a weighing device, the precision is high, so that the amount of one product is low and the amount of two products is low. Melting is high, and the heat is also controlled. The fire is fierce and the liquid is low, and the fire is not high enough. When the liquid is properly metallurgy, then according to the standard. In this way, it is appropriate and fast, so that the liquid is distributed in the same range, so that it can be produced, the shape is high, and the weight is appropriate.
In addition, there is also a new method of melting. Collect all the materials, regardless of two or one, and put them into remelting. However, when considering the composition of the product, there may be some factors involved. Therefore, it is necessary to improve the quality of the product, remove its quality, and keep its refinement. When the product is completed, it is like the previous method, so that it can be used in a new system.
All the methods of combining the product require the careful management of the craftsman, and the skilled use of the technology, so that the second and the first can be used, so as to pass the flow of the product and the use of people's livelihood.

As for the chemical activity, 2-%E5%90%A1%E5%94%91 slightly more sensitive than 1-%E5%9F%BA%E5%90%A1, in the case of weak bases and weak acids, it can also respond slightly, but it should be slow and controllable, without greatly damaging its quality. In the oxidation environment, although there are traces gradually, its antioxidant ability can still be maintained for a long time.
Under the action of light, 2-%E5%90%A1%E5%94%91 or show a discoloration. This non-qualitative change is the fine-tuning of the photoinduced structure. When the light goes away, the color gradually recovers.
In summary, 2-%E5%90%A1%E5%94%91 based on 1-%E5%9F%BA%E5%90%A1, the physical and chemical properties have seen new changes in inheritance, so they can develop different capabilities in many fields.

In the land of Huaxia, the use of fire has been around for a long time. The application of fire involves a wide range of fields and has a profound impact on the livelihood of all people.
In the realm of cooking, fire is the key. In the past, the ancestors drank blood and drilled wood from the flue people to get fire, and only then did they start the chapter of cooked food. Cooked with fire, the taste of food is more beautiful, nutrition is easier to absorb, and people's physique is also getting stronger. Grain is boiled in a kettle, boiled by fire, into fragrant and soft porridge; animal meat is roasted in a tripod, and it is roasted by fire to melt delicious food. Fire makes the way of eating more and more complicated, and the foundation of civilization can be laid.
In the world of smelting, fire shows a miraculous effect. Metals such as gold, copper, and iron are smelted by fire to form. Craftsmen control the temperature of fire, making weapons and utensils. Sharp swords, which have been tempered and hardened, are sharp tools for protecting the home and the country; exquisite tools, born in fire, or for sacrificial rituals, or for daily use. Fire promotes the progress of craftsmanship, and the journey of civilization strides forward.
In the path of lighting, fire also has great contributions. When night falls, the light of torches and oil lamps dispels the darkness. In the past, people lit candles in the middle of houses or set up beacon towers next to the road. The light of candles adds warmth to family gatherings; the smoke of beacons provides peace and tranquility to convey military conditions. Fire gives people light and hope in the dark.
In the industry of pottery, fire casts brilliance. The soil is shaped by the hands of the craftsman, and calcined in the kiln through fire to form a strong and beautiful pottery. Or an urn for drawing water, or a jar for holding things. Fire gives new life to the soil and makes it a carrier for the inheritance of civilization.
All in all, fire has made indelible achievements in many fields such as cooking, smelting, lighting, and pottery. It is an important driving force for the evolution of human civilization.

In today's world, there are two flavors of nitrate, one is flame nitrate, and the other is mirabilite, each of which has its own unique market prospects.
