In ancient times, mirages were often regarded as a mysterious and bizarre phenomenon, and their main uses were reflected in many ancient records and legends.
Although "Tianguan Kaiwu" did not specifically describe mirages, in the context of ancient culture, the main uses of mirages were as follows. First, in the cognition of the ancients, mirages were often connected with legends of gods and monsters. Due to the lack of in-depth understanding of natural science, when the ancients witnessed the ethereal and ethereal scene of mirages, such as fairy palaces and castles, they thought it was the mirage in the sea (a mythical large clam), and regarded it as a symbol of gods and monsters or fairyland. Therefore, it was endowed with religion and mystery. It was often used in the creation of stories and legends of gods and monsters, carrying the imagination and awe of the ancient people for the unknown world.
Second, mirages occasionally provide creative inspiration for scholars and writers. Its dreamlike and bizarre beauty inspired the creative enthusiasm of poets and painters. Literati depicted the fantasy of mirages in poetry, while painters showed their unique style with pen and ink, adding a different theme and artistic conception to the field of artistic creation, enriching the expression content of ancient literature and art.
Third, in some coastal areas, the appearance of mirages was regarded by fishermen as a harbinger of weather or fortune. Although there is no scientific basis, they rely on their experience and traditional understanding to connect the appearance of mirages with subsequent weather changes, good or bad fishing opportunities, etc., becoming a reference for guiding daily life and production activities, and to some extent influencing the behavior and decision-making of local people.

Saltpeter is a monovalent dioxy compound. Second, when mixed with sulfur and ignited, it can show unique chemical properties.
When saltpeter and sulfur are placed in fire, saltpeter will decompose when heated. The main component of saltpeter is potassium nitrate ($KNO_ {3} $). When heated, potassium nitrate will react as follows: $2KNO_ {3}\ stackrel {\ Delta }{=\!=\!=} 2KNO_ {2} + O_ {2}\ uparrow $, this process will release oxygen. Sulfur, chemically known as sulfur ($S $), is flammable. When burned in air, it reacts with oxygen: $S + O_ {2}\ stackrel {ignited }{=\!=\!=} SO_ {2} $.
When the two are mixed and ignited, the oxygen decomposed from saltpeter can provide more sufficient combustion conditions for sulfur combustion, making sulfur combustion more intense. Not only that, but the presence of potassium in saltpeter also gives the flame a unique flame color. The flame color reaction of potassium is observed through the blue cobalt glass and is purple. The phenomenon produced by the mixed ignition of the two is very different from the combustion of sulfur alone, and the chemical changes involved in the reaction reveal the unique chemical properties of saltpeter and sulfur, which are also crucial in the preparation of gunpowder in ancient times.

It is also a medicine for making fire. Its nature is fierce, and it is used properly, and it heals diseases like a god; if it is used inappropriately, the harm is not light. When it comes to the art of sulphur and alchemy, you should especially pay attention to it.
Where nitrate yellow is refined, the first priority is to choose the material. It is necessary to choose pure ones, and the impurities do not exist before they can be used. If its quality is not good, it will be useless to refine, and other diseases will be reborn. And when choosing, it must also be in line with the season, and follow the ancient method, and do not act rashly.
The place where the medicine is refined should be kept away from the crowd, and a remote place should be chosen. To prevent its violent nature, in case of failure, it will harm the innocent. The surroundings must also be empty, free from other things, so as not to spread to other things and cause fire when the medicine is released.
The tool for refining medicine must be excellent. The material is sturdy and can withstand changes in the heat. If the tool has flaws, I am afraid that the medicine will be broken before it is ripe, and the previous efforts will be wasted, and there is a risk of hurting people.
As for the heat, it is the most critical. At the beginning, it is appropriate to slow down, so that the medicine will gradually melt, and then gradually increase the fire. Don't be too hasty. If you are too hasty, the medicine will be easy to burn and lose its nature; if it is too slow, the medicine will not gather and it will be difficult to become a pill. The beauty of the heat lies in the mind of the alchemist, and it can be passed on without words.
Furthermore, the method of sulphur and alchemy is secret but not passed on. You must learn from your teacher, and follow your teacher's instructions carefully. You must not speculate privately or change your method arbitrarily. A teacher, accumulating years of experience is not easy to obtain. According to your teacher's teaching, the right way is the right way.
Also, after your pill is completed, you should also pay attention to collection. Store it tightly in a porcelain bottle and place it in a cool and dry place. You must not be near a fire, nor mix it with other medicines, so as not to disturb the medicinal properties and cause mutation.
In short, the matter of sulphur and alchemy is related to human life, and you must not be careless. All kinds of attention have been tested by predecessors, and future generations should keep it in mind and not slack off a little.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. However, Jun's question is vague, and the meaning of "n-%281%2C1-%E4%BA%8C%E7%94%B2%E5%9F%BA%E4%B9%99%E5%9F%BA%29-2-%E8%8B%AF%E5%B9%B6%E5%99%BB%E5%94%91%E6%AC%A1%E7%A3%BA%E9%85%B0%E8%83%BA%E5%AF%B9%E7%8E%AF%E5%A2%83%E6%9C%89%E4%BB%80%E4%B9%88%E5%BD%B1%E5%93%8D" is unclear, so it is difficult to answer accurately.
If Jun means "what impact does sulfur dioxide have on the environment", it can be described as follows. Sulfur dioxide is a common atmospheric pollutant, and its impact on the environment is quite serious. In the atmosphere, sulfur dioxide easily reacts with oxygen, water vapor, etc., generating acidic substances such as sulfuric acid, which in turn causes acid rain. Acid rain falls, which will seriously damage the soil and cause soil acidification. Among them, nutrients are lost, fertility is reduced, and many plant growth is affected. It will inhibit crop yield and quality, and will also destroy forest ecosystems, causing trees to wither.
Furthermore, sulfur dioxide emissions in the air can reduce atmospheric visibility, affect air quality, and endanger human health. It irritates the human respiratory tract, causing respiratory diseases such as cough and asthma, and especially affects the elderly, children, and patients with respiratory diseases. In the water environment, acid rain flows into rivers and lakes, which will acidify water bodies, affect the survival of aquatic organisms, and destroy the water ecological balance.
Therefore, sulfur dioxide has adverse effects on many aspects of the environment, and controlling its emissions is crucial to environmental protection.

"Tiangong Kaiwu" reports that saltpeter (n -% 281% 2C1 - dimethylacetamide) encounters other compounds, and the reactions that occur are quite diverse.
Saltpeter is active and highly oxidizing. In case of flammable substances, such as sulfur, charcoal, etc., it can cause violent combustion and even explosion. The principle of this reaction is that saltpeter is decomposed by heat, releasing oxygen and supporting combustion of other substances. Just like the ratio of ancient gunpowder, saltpeter, sulfur, and charcoal are mixed in a specific ratio. Once ignited, it will explode instantly, and its power is amazing.
If it encounters metal elements, such as iron, copper, etc., under suitable conditions, a redox reaction can occur. The oxygen of saltpeter binds to the metal to form metal oxides, and the metal's own valence increases and is oxidized. For example, under certain conditions, iron reacts with saltpeter, and iron is oxidized to form iron oxides. This reaction often occurs at a specific temperature and medium.
When saltpeter meets acid substances, there is also a different reaction. In case of strong acids such as sulfuric acid, new compounds and gases may be formed. In this process, the nitrate ion of saltpeter interacts with hydrogen ions and other ions in the acid to recombine to form nitric acid and other products. Some reactions may also be accompanied by the phenomenon of gas escape.
In addition, saltpeter can also react with certain salts. According to the principle of metathesis reaction, if the reaction can form difficult-to-ionize substances such as precipitation, gas or water, the reaction can occur. If saltpeter is mixed with a salt solution containing silver ions, nitrate ions combine with silver ions, and silver nitrate precipitation may be formed. This precipitation has unique properties and is easy to decompose under light.
Saltpeter is active due to its own chemical properties. When it encounters many compounds, it will undergo different types of reactions such as redox and metathesis according to the chemical characteristics of the other party, and deduce a variety of chemical processes on the stage of chemical changes.
