What is the Chinese name of this substance?
Because I don't know the specific meaning of "this substance", I take the "salt" in "Tiangong Kaiwu" as an example to answer as follows:
Salt eaters are the ancestors of all flavors and are necessary for people's livelihood. "Tiangong Kaiwu" has a saying: "Where the salt production is the most different, the sea, pool, well, soil, cliff, sand and gravel are slightly divided into six kinds, and the sea is the bulk." The wide range of sources of this salt, the most considerable production of sea salt.
The production of sea salt depends on the time and place. First, the seawater is introduced into the beach, and it evaporates during the sun exposure. When the brine concentration gradually increases, it will re-enter the crystallization pool. After the hot sun evaporates, the sea breeze is brackish, and the brine then precipitates into salt grains. It is as white as snow, and it is The production of this sea salt is roughly the same.
Pool salt is found in the inland saltwater lakes of the northwest. The lake water has a high salt content, the summer is hot, the water evaporates, and the salt precipitates from the lake and gathers at the bottom of the lake. The people take it, and it can be used after a little finishing.
The production of well salt is prosperous in the Shu land. Dig wells and springs to get saltwater, draw it from bamboo tubes, and then after suffering, the water vapor rises, and the salt gradually condenses, and finally becomes well salt. Its method is exquisite, condensing the wisdom of the ancients.
As for soil salt, cliff salt, and sand and gravel salt, although the output is not as good as the first three, they also have their own methods, which are used by one side's livelihood.
The use of salt is not just for seasoning. When cooking, it can enhance freshness and flavor, making delicious dishes mellow; when pickling, it can keep food from being bad for a long time, and the flavor will remain over time. And it is important in many fields such as medicine and industry. It is actually an indispensable thing in the world.
What are the chemical properties of this substance?
This substance has a wide range of chemical properties. It is flammable. Under suitable conditions, it can burn violently in the event of an open flame or hot topic, just like a fire phoenix dancing in the air and a raging flame. This is because the molecules in the substance are rich in energy, and when combined with oxygen, they can quickly release a large amount of heat energy.
It is also oxidizing, and can capture electrons from other substances in a specific reaction, causing its valence state to increase, just like a king grabbing something, showing its majesty. This property often causes the reacting substance to oxidize, change its color, or change its texture.
And it is reducing, capable of giving its own electrons to other substances, increasing its own valence state. It is like dedicating one's own strength to help other things complete the transformation, and it is often found in reactions such as metal smelting.
Its acidity and alkalinity are also important chemical properties. If it is acidic, it can neutralize with alkali, just like yin and yang are harmonized to form salt and water. Its acidity is different, and the intensity of the reaction is also different. If it is alkaline, it can be combined with acid, and the transformation of this neutralization can also be completed.
Stability is also a key property. In some cases, the material is stable in nature and can be stored for a long time without changing easily, just like a rock. In case of special conditions, such as high temperature, high pressure, catalysts, etc., it may also break this stability, trigger chemical reactions, and initiate wonderful changes. These various chemical properties are intertwined to create a rich and diverse chemical picture of the substance, playing a crucial role in the field of chemistry.
In which fields is this substance used?
A certain substance has wonderful uses in many fields. In the field of agriculture, it can help crops grow, increase soil strength, and retain water and soil. If it is used as a base fertilizer, it can make seedlings thrive, the leaves are bright green, the resistance to diseases and pests is also strong, and it can prevent field desertification and compaction.
In the world of craftsmanship, this substance is widely used. In civil construction, it is a adhesive, which makes bricks and stones stable, and the built house is durable. In pottery production, it can be added to change the characteristics of clay, and the fired pottery is delicate in texture, warm in color, and regular in shape.
In the way of medicine, it has certain medicinal uses. It can be used as medicine to treat diseases, or externally to reduce swelling and pain, or internally to regulate internal organs. For those with trauma, swelling and pain, apply it to remove blood stasis and reduce swelling; for those with spleen and stomach insufficiency, use it in combination according to the prescription, which can slow down symptoms and help transportation.
In daily life, it is also indispensable. If you make clean things, you can remove dirt and make utensils clean; in the printing and dyeing process, you can help dye to fix color, and the dyed color is bright and lasting, and the fabric is colorful.
And in sacrificial ceremonies, it is often a offering, showing solemnity and piety; in craftsmanship decoration, it is carved and shaped into exquisite ornaments, increasing the elegance of the hall. All of these show that this substance has important uses in various fields and is relied on by the world's life and production.
What is the preparation method of this substance?
The method of making a certain substance is related to workmanship and number of techniques, and it needs to be decided according to its physical properties and materials. This is to imitate the classical saying of "Tiangong Kaiwu" and describe the method of making a substance.
If you want to make porcelain, first take the soil of Gaoling, which is delicate and sticky, and is the base material for porcelain. After mining the soil, put it in clean water to wash it, remove its sand, gravel and impurities, and make the soil pure. Then, pile the washed soil on the ground, cover it with grass, and age it for several months. The aged soil is soft like paste and easy to shape.
Then, by hand or with the help of a roulette wheel, shape the soil into the desired shape, such as bottles, jars, bowls, and cups. When shaping, the craftsman needs to be careful and steady, so that the utensils are well-proportioned around the circumference. The shaped blank should be placed in a ventilated place to dry in the shade, and should not be exposed to the sun to prevent dryness and cracking.
When the blank is semi-dry, use a special pen, dip it in paint, and draw the decoration on the blank. The pattern, whether it is landscapes, flowers and birds, or characters or auspicious beasts, is ingenious. After painting, apply a layer of transparent glaze, which can make the porcelain surface smooth and protect the decoration. < Br >
Finally, the glazed billet is placed in the kiln for firing. The kiln temperature needs to be precisely controlled. First, it is baked slowly over a low fire, so that the water in the billet is exhausted, and then it is gradually heated up. The porcelain kilns of porcelain firing are different from firewood kilns, coal kilns, and gas kilns. The porcelain burned in firewood kilns has a warm color and unique charm. After several days of firing, when the kiln temperature is cooled, the kiln is opened and taken out, and a piece of exquisite porcelain can be made.
Another example is the method of ironmaking. The iron-rich ore is selected, broken into small pieces, and put into the furnace in proportion to coke, limestone, etc. The coke is first ignited by fire in the furnace, and the coke combustion produces a high temperature, which reduces the iron ore to molten iron. The limestone combines with the impurities in the ore to form slag, which floats on the molten iron. When the molten iron is mature, open the mouth of the bottom of the furnace, let the molten iron flow out, inject it into the mold, and cool, it is pig iron. Pig iron can be tempered and forged to make various iron tools, such as agricultural tools, knives, etc.
The methods of making things are complicated, and they all rely on the wisdom and skills of craftsmen. They are passed down from generation to generation and strive for excellence.
What impact does this substance have on the environment?
The impact of a substance on the environment is related to ecological balance and the survival of all things, which cannot be ignored. Today, I will try to discuss it in the literary style of "Tiangong Kaiwu".
The material exists between heaven and earth, and it interacts with the environment, which is either beneficial or harmful. Looking at plants and trees, they can perform photosynthesis, absorb carbon and excrete oxygen, so as to moisturize the atmosphere, so that the air can last forever, which is also beneficial to the environment. And its root system is intertwined, solidifying soil and retaining water, so that water and soil will not be lost, and mountains and rivers can be stabilized.
However, there are also various substances, which are harmful to the environment. If it is a mineral, when it is refined, it often releases all kinds of poisons in water and soil. Sulfur and mercury are mixed into rivers and rivers, polluting people's drinking water and causing illness and health; they disperse into the soil, making the soil barren and barren, and making it difficult for plants and trees to grow. As for coal, although it can be used for people to heat and cook, when it burns, the thick smoke dies in the sun, sulfur oxides rise in the air, and when water encounters acid rain, it erodes everything, destroys forests, and ruins crops.
Then like all kinds of chemical substances, it is not easy to dissolve. If it is abandoned in the wild, it will accumulate for a long time but not disperse. Over the years, it will be bad for the ecological order. Plastic genera, or enter rivers, lakes and seas, harming aquariums. Fish and turtles eat by mistake, causing gastrointestinal obstruction, and their lives are in danger; birds pecking it, it is difficult to escape, and the ecological chain is therefore broken < Br >
There is also manure produced by animal husbandry. If it is not disposed of properly, its foul gas will diffuse, and the sewage will seep into the ground and sewage groundwater. However, if it is used reasonably, it can be used as a fertilizer for the field and turn harm into profit.
In a word, matter is in the environment, and interests depend on each other. People should understand its reasons, use it wisely, seek advantages and avoid disadvantages, so as to ensure the safety of the environment, the prosperity of all things, and the coexistence and prosperity of heaven and earth for generations.
