Oxiran-2-Ylmethyl 4-Methylbenzenesulfonate

The chemical structure of this product is a profound question. Although the "Tiangong Kaiwu" is widely involved in various techniques and products, it does not describe the specific chemical structure of this product in detail.
Because when "Tiangong Kaiwu" was in place, the scientific understanding was not as profound as it is today. At that time, chemistry had not yet become a systematic study, and it was difficult to accurately describe the microstructure of matter.
If you speculate in ancient Chinese, you can say: This product may be composed of various elements in a specific order and in a specific way. However, this is only an illusion.
Today's science, with advanced instruments and theories, can analyze matter to the atomic and molecular levels. However, according to ancient Chinese, it can only be explained in simple terms. Or it is said that this product is condensed by all kinds of essence between heaven and earth, and through the work of creation, it has formed this unique shape. Its internal structure, or like the interweaving of warp and weft of weaving brocade, is well organized; or it is like the layers of softstone stacked on top of each other, stable and orderly. But this is all based on the ancient meaning, and it is difficult to determine what its chemical structure is. Although I respect ancient science, it is difficult to give a definite answer to the modern scientific concept of chemical structure according to "Tiangong Kaiwu". I can only express my conjecture a little to express my thoughts on the differences between ancient and modern learning.

The main users of this product are all kinds of uses. It can be used for labor and livelihood, between farmers and mulberry crops, it can help farmers to cultivate deeply and improve the output of the fields. Such as ploughing tools for plowing the land, breaking the soil and turning the soil, making the land loose and fertile, which is conducive to the growth of seed beds, helping seedlings to thrive, and can obtain fertile grain when harvested in autumn.
In the industry of craftsmanship, it is also very useful. The axe saw in the hand of the woodworker can cut wood into wood, make tools, make tools, tables, chairs, and beams of buildings. All rely on these tools to form their shapes, and the exquisite work is revealed.
In martial arts, this product is also indispensable. Blades, swords, spears and halberds are sharp tools for defending the home and the country and fighting on the battlefield. Those who hold sharp blades can defend the enemy in front of the battle, protect the peace of the home and the country, raise the army's prestige and boost morale.
In daily life, it is also a help for convenience. In the kitchen, knives, pots and kettles can cook delicious food, satisfy the desire of the stomach, and make the family share the joy of eating.
In addition, in the living room, masonry, rubble, plaster, wood and stone are all important things for building houses, protecting everyone from the wind and rain, and settling down. This product has a wide range of uses, or is related to the foundation of people's livelihood, or helps the intensive research of skills, or is used to protect the country. It has great contributions in all kinds of affairs.

The method of production of a certain product is exquisite and contains ancient wisdom.
In its initial stage, the raw materials must be harsh. The earth and the earth are beautiful, so as to fit the required characteristics of the product. For example, if the product is made of high-quality materials, it must be made of high-quality materials, and its quality, including low quality, in order to lay the foundation for the quality of the product.
However, in this period of time, the control of the heat is of paramount importance. "Heavenly Works" said: "Where the gold is high, and the heat is deep, there is a good quality." This also applies to this product. For example, it is necessary to change the color of the fire, the first flame is red, the first flame is blue, and the flame is full of smoke, so that the best heat can be achieved. The essence of this product can be improved, and it is cooked in the ground. If the heat is not yet available, the quality of the product will not be improved; if the heat is not good, the quality of the product is easy to be brittle and used.
Furthermore, the shaping of the product, especially the skill of the craftsman. It depends on the use of the product, the shape and other factors, with ingenuity, to give the material a perfect shape. For example, in pottery, craftsmen use their hands to spin the mud, and the weight is urgent. The shape of the billet is formed in the period, or the shape, or the pot, or the bottle.
To make the product more perfect, it is also indispensable to repair and polish. Taking jade carving as an example, when carving jade, it is necessary to use sand, cloth and other objects to polish it backwards, so that the surface of the jade is smooth, the texture is clear, and the color is good. This repair and polishing method cannot remove the defects on the surface of the product, but also can highlight the taste of its presence.
Of course, the production method of this product, such as the fusion of materials, materials, shapes, repairs, etc. Only by combining the methods can we create the best quality products, which can condense the wisdom of the ancients.

The Quality Standard of this product is a criterion related to the quality of the product, which is extremely important. Although "Tiangong Kaiwu" does not directly explain the Quality Standard of this specific product, it contains the way of quality control in the description of various processes, which can be studied.
For most products, the quality standard is the first material selection. For example, "Tiangong Kaiwu" talks about many manufactures, all of which emphasize the careful selection of materials. Good materials are the foundation of high-quality products. If the material is not good, even if there are clever skills, it is difficult to become a good product. Take the casting of swords as an example, you need to choose the best fine iron to cast a sword with a sharp edge and strong quality. The same is true for this product. The selection of materials must be strict, and the purity and characteristics of the material must be considered to meet the needs of the product.
Secondly, the production process is also the key to quality. "Tiangong Kaiwu" details many process steps and skills. Each link is interlocked and cannot be lost. Each process has specific standards and requirements, such as firing ceramics, and slight deviations in heat and time control will cause product defects. The production of this product also needs to follow precise process procedures, from initial processing to finished products, step by step, rigorous, to ensure that the quality of all links is up to standard.
Furthermore, the appearance and specifications also belong to the category of Quality Standards. The appearance of the product should be flat and smooth, without obvious defects, cracks, etc. Specifications must meet the established size, shape and other requirements, and the deviation is within the allowable range. Such as the appliances mentioned in the book, there are corresponding specifications and regulations, and this product should also follow to ensure product consistency and versatility.
In addition, the performance aspect cannot be ignored. The product must have the performance and function it should have, and be stable and reliable. Such as mechanical devices, it should operate smoothly and last for a long time. This product should also undergo strict performance testing to meet the needs of use in order to meet the Quality Standard.
In short, the product Quality Standard covers materials, craftsmanship, appearance specifications and performance, and needs to be fully considered and controlled to achieve high quality.

When storing and transporting something, there are many things to pay attention to.
When storing, the first location should be selected. When choosing a high and dry place to prevent the rain from soaking and causing the object to rot. If it is located in a humid place, the water is easy to accumulate, and the objects are damaged by moisture, which will only increase the loss. And the warehouse must be well ventilated. If the air is not smooth, the filth will accumulate, or the items will be mildewed. It is a ventilated setting, which cannot be ignored.
In addition, there are also rules for stacking items. When arranged in order according to their category, size, weight, etc. Heavy objects are under and light objects are on top, so as to avoid the risk of collapse. And between the stacks, it is advisable to leave an appropriate gap, one is convenient for inspection, and the other is conducive to ventilation and heat dissipation.
As for transportation, the first thing is the choice of utensils. Depending on the characteristics of the object, if it is fragile, it should be protected with soft padding, such as silk cotton, felt blankets, etc., to prevent it from breaking due to bumps and collisions. If it is perishable, it is necessary to have cold and thermal insulation equipment, such as the genus of ice, to keep the object fresh.
During transportation, the wearer should be cautious. Road in distress, narrow road, slow and steady driving to avoid its shock. And pay attention to the weather, if there is a rainstorm, wind, blizzard and other bad weather, when looking for a safe place to take shelter, wait for the weather to improve before going, must not rush forward, causing damage.
In short, regardless of storage or transportation, it is necessary to carefully plan and handle carefully to ensure the integrity of the goods and avoid loss.
