1-Naphthalenesulfonate, 3-Olato-4-[(E)-2-(2-Olato-1-Naphthalenyl)Diazenyl]- 3-Olato-4-[(Z)-2-(2-Olato-1-Naphthalenyl)Diazenyl]-1-Naphthalenesulfonate, Chromium(3+) Sodium Salt (1:1:1:2)

To understand the chemical structure of this substance is to seek knowledge. In ancient terms, this is the key to exploring the composition of matter.
The chemical structure of a substance is related to its properties and functions. To understand the structure of this substance, one should carefully examine its elemental composition, how the elements are connected, and what kind of structure is formed.
Or to observe the arrangement of its atoms, such as the stars listed in the sky, has its specific order. What kind of bonds are combined between atoms, covalent bonds? Ionic bonds? All of this needs to be investigated in detail.
Or to observe the configuration of its space, whether it is a plane state or a three-dimensional shape. If some organic substances have different spatial structures, their properties are very different.
In order to understand the chemical structure of this substance, many means are also required. By means of experiments, observe its reaction and measure its physical properties, such as melting point, solubility, etc. You can also use the help of instruments, such as spectroscopy and mass spectrometry, to explore its microscopic secrets.
After this exploration, it may be possible to understand the approximate chemical structure of this substance. However, the way of science often needs to be repeatedly verified and refined before it can reach a definite conclusion. Although it is said in ancient Chinese, the purpose is still to understand its structure. The investigation of its structure is indeed the priority of scientific exploration.

The main use of a substance is related to people's livelihood and all kinds of industries, and it is very extensive.
In the field of daily use, it is an indispensable material. For example, many utensils used at home depend on it. In the theory of common utensils, either because of their strong quality or because of their stability, they can be used by people for a long time, for the needs of food and daily life, to facilitate life, and to make daily use smooth and worry-free.
In the business of construction, it also occupies a key position. Building houses is the choice of cornerstone beams and pillars. Because of its ability to bear, sturdy and reliable, large buildings can stand firmly and protect all people. And in the construction of roads and bridges, it also plays an important role in ensuring the smooth flow of transportation, promoting business and trade, and facilitating the passage of people.
In the way of manufacturing, its use is more significant. In the system of equipment, according to the characteristics required by different equipment, either take its toughness and wear resistance, or take its lightness and dexterity, to help the equipment operate efficiently and promote the progress of industry. In the manufacture of precision instruments, it relies more on its precise characteristics to ensure the accuracy of the instruments, and makes great contributions to scientific research, medical treatment and other fields.
The work of farming mulberry is also assisted by it. Farming equipment relies on its construction, which is tough and durable, to help farmers work and harvest, and to ensure the supply of food. And in terms of irrigation facilities, its characteristics also contribute to the development of water conservancy and promote the prosperity of agriculture.
In addition, it also has important uses in important places of military and national defense. The manufacture of weapons and armor requires its excellent materials to defend the enemy and the country, and to protect the territory and the people.
To sum up, this material is widely used, and it is indispensable from daily use to the important tasks of the country. It is actually an important thing for the national economy and people's livelihood.

"Tiangong Kaiwu" says: "Anyone who uses this object should know all the things to pay attention to, so that it can be used to the best of its ability without fear."
First, before using it, you must carefully observe its quality. Each object has its own nature, whether it is strong or soft, or dry or moist. If it is a tool of gold and stone, check its texture for density and flaws. If it is strong, it will be resistant to damage, and if it is sparse, it will be easy to fold. If it is iron for a sword, it needs to be carefully selected, and impurities will be removed before a good material can be obtained. When it is used, it is appropriate. Different things are suitable for different situations and different things. Taking farming equipment as an example, ploughshares are suitable for deep plowing, scythes are suitable for cutting ears and harvesting crops. If they are used incorrectly, they will achieve twice the result with half the effort. And the intensity and frequency of use should also be appropriate. If the force is too strong, it will be vulnerable to utensils; if the frequency is improper, it will also affect the efficacy.
Third, the matter of care should not be ignored. After use, it should be properly placed, such as wooden utensils, to avoid moisture to prevent corrosion, and to keep in the shade to avoid cracking. Metal objects should be descaled and rust-proof, and oiled for maintenance, so as to prolong their use. If the maintenance is not good, even the good utensils will quickly decay.
Fourth, know the change. During the use of objects, due to factors such as environment and duration, there may be changes. The user should be keenly aware and adjust the usage in a timely manner. If the old sickle blade is blunt, it needs to be sharpened to restore its benefits; if the ancient axle is worn, it needs to be repaired and reinforced.
All these matters of attention are related to the effectiveness and lifespan of the object. Only by focusing on this can we make the best use of the object and get twice the result with half the effort, so that the object can be used for a long time.

Its production process is quite complicated. As recorded in "Tiangong Kaiwu", all kinds of creations have complicated processes.
Taking porcelain making as an example, the beginning is to mine soil. You need to find the delicate and suitable porcelain soil in a specific place. This soil is related to the texture of the porcelain and cannot be ignored. After picking, you must clear the mud, remove its coarse impurities, and make the mud pure. Then the mud is refined and repeatedly kneaded to make the mud dense and uniform, so that the mud can be made into a billet.
There are also many exquisite techniques for making billets. Either by hand, or with the help of pottery wheels, the craftsman carefully shapes it according to the shape of the utensils. After the billet is formed, it is fired in the kiln. It is very important to control the temperature of the kiln. It is necessary to be familiar with the changes in the temperature, when to heat up, when to stabilize the fire, and when to cool down. If there is a slight difference, the porcelain will have flaws.
Another example is smelting iron. First look for iron ore, and when mining, know the direction of the ore veins. The ore is mined and smelted in the furnace. The structure of the furnace and the choice of fuel are all key. During smelting, observe the heat, identify the color of the molten iron, and wait for the molten iron to mature before casting. The method of blowing the wind and the proportion of ingredients during this period are all secrets.
The art of weaving, from cotton mining, to elastic flowers, spinning, to weaving and dyeing, there are many steps. The elastic flowers make the cotton loose and easy to spin; the spinning should be spun evenly; the weaving needs to be carefully shuttled through the warp and weft; the dyeing needs to prepare suitable dyes to dye bright colors.
Therefore, looking at all kinds of crafts, from the selection of raw materials to the processing and production, every step requires exquisite skills and rich experience, which can be said to be very complicated.

There are things today, what is their impact on the environment? This is a key issue related to ecological balance and the survival of all things.
If this thing is beneficial, it will contribute greatly to the environment. For example, a green tree can absorb carbon and release oxygen, filling the air between heaven and earth. Every hot summer, the green trees are shady, which can reduce the temperature of the surroundings and reduce the heat slightly. Its root system also solidifies soil and retains water, so that water and soil are not lost, and rivers and streams can be long and clear. And it provides a habitat for all living things. Birds, beasts, insects and fish all depend on it, and this ecological chain can be stabilized.
However, if this thing is a victim, its disaster is also severe. Such as the discharge of dirty gas and the release of poisons, it can disrupt the order of the environment. Dirty air permeates, covering the blue sky, and people are in the middle of it, prone to all kinds of diseases. Poisons enter rivers, lakes and seas, aquatic things are difficult to survive, and the water quality deteriorates. Not only is there no water to drink, but also causes ecological changes, and many species may be wiped out.
There are also sundries abandoned, piled up like mountains, occupying land and smelling rancid, attracting mosquitoes to breed and spread diseases. These are all signs that things are unfavorable to the environment.
Furthermore, the entry of foreign objects may break the balance of the native ecology. New things have no natural enemies to check and balance, reproduce wantonly, squeeze the living space of native species, and damage the diversity of organisms. Therefore, in order to understand the impact of this thing on the environment, it is necessary to carefully investigate its nature, its quantity, and its location. Make good use of beneficial things and strictly control harmful things, so as to maintain the beauty of the environment and the balance of ecology, so that all things can coexist harmoniously and continue from generation to generation.
