The chemical structure of this product is quite unique. In its structure, the atoms are arranged in an orderly and delicate manner, like a natural chess game. The atoms are in their own positions, but they are closely connected to each other and interact with each other to build a stable structure.
Looking at the characteristics of its chemical bonds, most of them are covalent bonds. This covalent bond is strong and stable, so that the atoms are firmly bonded, giving the product a certain degree of physical and chemical stability. And the bond length and bond angle follow specific laws. The bond length is moderate to ensure that the atomic spacing is just right, neither too close to repel each other, nor too distant to loosen the structure; the precise bond angle makes the entire molecular structure exhibit a specific spatial configuration, or a symmetrical and beautiful shape, or a unique distorted shape, which all have a profound impact on the properties of the product.
Looking at its functional group, this is the key to the chemical activity of the product. The specific functional group gives the product unique chemical properties, which can undergo specific chemical reactions with other substances, or hydrophilicity, or lipophilicity, and exhibit different behaviors in different environments. And the position of the functional group in the molecular structure is also extremely important. Its location not only affects the spatial arrangement of the molecule, but also affects the difficulty of its interaction with external matter.
From the perspective of the overall structure, the molecule may be linearly stretched, such as a compliant silk thread, which can be flexibly curled under certain circumstances; or it may be a three-dimensional network, like a solid fortress, with a high degree of stability and rigidity. This unique chemical structure lays the foundation for the performance of the product, enabling it to play a unique role in many fields. It is actually a contrived thing.

What are the main uses of this product? Let me tell you in detail.
According to the "Tiangong Kaiwu", all kinds of utensils in the world have their uses. It is either related to people's livelihood, food, housing, transportation, or related to the needs of labor and production, or tied to the system of etiquette and regulations.
Let's talk about the needs of people's livelihood first. Take the loom as an example. The loom is the important device for weaving clothes. "Tiangong Kaiwu" states: "All weaving fabrics, including cloud flowers, oblique texts, elephant eyes, etc., are all imitated by flower machines." The use of looms for people's livelihood can enable people to get clothing to cover their bodies, withstand cold, winter, heat, and heat, and can produce various colors and patterns, enriching people's clothing.
As for labor and production, the waterwheel is also an important thing. The book says: "The waterwheel can carry water and irrigate the fields, and the effect is quite great." In terms of agriculture, the waterwheel can divert water from rivers and rivers, irrigate 10,000 hectares of fields, make the harvest smooth, and the grain harvest is abundant, which is related to the livelihood of all people.
On the etiquette and regulations, the use of ritual instruments should not be underestimated. Such as tripods, ancient heavy weapons, although the "Tiangong Kaiwu" does not describe its production process in detail, it symbolizes power, status and dignity on ceremonial occasions such as sacrifices and court meetings, carries profound cultural connotations, and maintains social order. From this perspective, the uses of various products, whether practical or cultural, play a crucial role in the survival and development of society.

There are crucial steps in the synthesis of things. At the beginning, it is necessary to examine the materials in detail. The quality of the materials is related to the quality of the finished product. It is necessary to choose fine materials, which can be used as the foundation. Like casting a sword, you should seek good iron, remove all impurities, its strength is like stone, and its toughness is like rattan, so you can hope for a good tool.
Then, plan the blueprint. This is the key to the layout of the plan. If you are in a large building, you must first draw its shape and determine its rules. Where is the beam and where is the column, the size is fine, all need to be clearly analyzed. Make the worker know what it is, and also know why, so that you can follow the order and not be chaotic.
Furthermore, apply skills and arts. This is the reality of practical use. The craftsman uses his ingenious hands to transport various tools to form them. Or chop or chop, or cast or forge, the technique is exquisite, like a butcher to solve an ox, with ease. Every knife, every hammer, pours your heart and soul into the object.
Again, check and correct the deviation. In the system, check from time to time, observe the accuracy of its shape, and observe its purity. If there is a deviation, it will be easier immediately, and do not keep the flaws, so as to ensure the excellence of quality.
In the end, polish and perfect. When the utensils are first formed, they are still raw jade and unpolished. They need to be carefully polished, moisturized in color, and enriched in texture, so that they can be in a perfect state and shine.
All these are the key steps in the synthesis of the objects, which are interlinked and indispensable. If you want to do good things, you must first understand this way, follow it, and you can almost get good products.

This product has all kinds of physical and chemical properties. Its quality is firm and dense, like the solid of gold and stone. Although it has been sharpened, it is difficult to damage its shape. It remains unchanged under force, and can bear the weight of thousands of cents without breaking. This is the toughness of its physical properties. Its body is smooth, and it is like jade. The friction coefficient is very small, and it helps the movement of things a lot. This is the lubricity of its physical properties.
Its color is pure, like autumn water for a long time, without the disturbance of variegated colors. It is pleasing to watch, and this is the color state of physical properties. As for its density, it is moderate and appropriate, neither frivolous like a flocculent, floating in the air; nor heavy like iron, difficult to hold.
Chemically, this product is quite stable and resistant to acid and alkali erosion. In case of strong acid, it is like a rock on the verge of flow, remaining motionless and does not react violently with it; in case of strong alkali, it is also like pine frost snow, Anzhiruosin, and is not easily corroded. However, under specific temperature and pressure conditions, it can also exhibit different chemical activities, and can combine with some special reagents to form new substances, which highlights its chemical properties and potential reactivity.
And because of its antioxidant properties, it can be placed in the air for a long time and is not oxidized by oxygen. For example, ancient bronze, it does not rust over time, which can maintain its original properties for a long time, providing many conveniences in preservation and use. All these various physical and chemical properties make this product useful in many fields, either as a material for utensils or as a reaction agent.

Today there is a product, compared with his likeness, what is its advantage? This is a key question.
