What are the main uses of 1,1,2,3,3,4,4-octafluoro-1,4-diiodobutane?

The author of "Tiangong Kaiwu" is written by Song Yingxing in the Ming Dynasty, and it is a great achievement of craftsmanship and technology. Looking at this question of "1, 1, 2, 2, 3, 3, 4, 4 - Eight Meridians - 1, 4 - Two Cakes and One Chicken", it is actually related to the game and entertainment equipment, mahjong.

The use of mahjong is not solely for entertainment. In the folk, after work, everyone sits around and rubs a game, which can relieve fatigue and increase friendship. It is a good recipe for social friendship. Friends gather, chat and laugh between cards, and the atmosphere is harmonious. It may eliminate barriers and add fun.

Furthermore, mahjong contains the beauty of strategy. Players need to judge the situation, observe the cards and deal with the cards, and weigh the trade-offs. Every step of the card is related to the overall situation. The art of card counting and the choice of eating and touching bars all show wisdom. Those who are good at mahjong seek opportunities to win in the change, which also exercises the mind and enlightens the mind.

And mahjong culture has a long history. Although the gameplay varies from place to place, it has regional characteristics. Its inheritance has been passed down for thousands of years, integrated into folk customs, and reflects the customs of one side. From the design of cards to the customization of rules, they are all rich in cultural heritage. Therefore, the functions of mahjong, entertainment, puzzle, and transmission, are indispensable in folk life.

What are the physical properties of 1,1,2,2,3,3,4,4-octafluoro-1,4-diiodobutane?

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, which explains the principle of all things in classical Chinese. Today, I answer this question in ancient classical Chinese:

If the husband is "1, 1, 2, 3, 3, 4, 4", it belongs to the series of numbers. As for the things of "Bachuan", "1, 4" and "two cakes and one chicken", if the physical properties are considered.

"Bachuan", the river flow is also fluid. Water is impermanent, can change with the device, and is fluid. Its quality is soft and can overcome stiffness. If it encounters resistance, it will be diverted, and it will follow the trend. It is soluble and soluble.

"1,4", if it is the representation of the number, the number of invisible, then it can be the quantity and order of things. Its physical properties are measurable and comparable, and it is the basis for measuring the quantity and order of all things. Although invisible, it can show the number and order of things.

"Two cakes and one chicken", if it is a pasta cake, it has a solid state, has a certain shape and volume, and the texture is crisp or tough, depending on the method of making it. Chicken, biological, also, has life activity, can move autonomously, has body temperature, its feathers can keep warm, and its bones and flesh have a certain physical structure, which can support physical activity.

All these things, each with its own unique physical properties, between heaven and earth, each showing its own state, each showing its own characteristics, and representing all things in nature.

What are the chemical properties of 1,1,2,2,3,3,4,4-octafluoro-1,4-diiodobutane?

"Tiangong Kaiwu" has a saying: "The hardware in the world is of different qualities. As for the chemical properties of two alum and one nitrate, each has its own wonderful." Two alum and one nitrate, among which alum are common green alum, alum, etc. Green alum, that is, ferrous sulfate crystals, is green in color, its sex is active, and it is easy to oxidize and change color when exposed to air. In chemical reactions, it is often used as a reducing agent. Alum, potassium aluminum sulfate crystal, has the ability to purify water, its hydrolysis can produce aluminum hydroxide colloid, adsorbs impurities in water.

And nitrate, mostly refers to potassium nitrate, which is a white crystal, easy to decompose when heated, and is a key ingredient in the preparation of ancient gunpowder, with strong oxidation. In the manufacture of fireworks, it is also indispensable, which can help burn and color. Dialum and nitrate are both important chemical substances that play an important role in traditional chemical processes such as alchemy, metallurgy, and gunpowder production. Although their chemical properties and uses have passed through the years, they are still important to future generations and are the cornerstone of chemical development.

What is the synthesis method of 1,1,2,3,4,4-octafluoro-1,4-diiodobutane?

If you want to combine the numbers "1, 1, 2, 2, 3, 3, 4 - Eight Wilderness - 1, 4 - Two Questions and One Tiger", you can have the following methods.

Looking at the sequence of numbers "1, 1, 2, 2, 3, 3, 4, 4", we can combine them in odd-even positions, or in order of number size.

First, you can group two in order. That is (1, 1), (2, 2), (3, 3), (4, 4), this is the method of combining the same numbers, and the numbers in each group are the same, which can represent the characteristics or states of a class.

Second, divide them by odd-even positions. The odd number is 1, 2, 3, 4, and the even number is also 1, 2, 3, 4. This division can be used to detect the relationship between parity digits, or to construct structures with parity and parity characteristics.

As for the mention of "Eight Wilderness" and "1,4 - Two Questions and One Tiger", if "Eight Wilderness" is a limited range concept, "1,4 - Two Questions and One Tiger" is a specific element combination requirement. On the basis of the above combination, if "1,4" is the key element, "1" and "4" can be placed according to a specific logic in the grouped or quantified structure. < Br >
If based on (1,1), (2,2), (3,3), (4,4), take out one "1" in a group and one "4" in a group, and the rest are arranged in the original order to obtain a new combination. Or in the parity combination, make the "1" of the odd number and the "4" of the even number correspond to form a new structure.

There are many ways to combine, and the appropriate method should be selected in detail according to the specific use map and situation to achieve specific purposes and effects.

What are the precautions for storing and transporting 1,1,2,3,3,4,4-octafluoro-1,4-diiodobutane?

In the storage and transportation of money and grain, which is related to the national economy and people's livelihood, it is a top priority, and many precautions cannot be ignored.

First, the storage place must be sturdy and open to prevent rain leakage and dampness from causing mildew and damage to the grain. And it should be inspected frequently, and if there is any damage, it should be repaired as soon as possible. As "Tiangong Kaiwu" said, "Every grain warehouse must choose a high and dry place, with masonry as the foundation, wood as the beam frame, covered with thick tiles", which is the foundation for protecting the grain.

Second, when storing grain, when the grain is dry and wet. If it is too wet, it will be perishable, and if it is too dry, it will be easily damaged. It must be dried in time according to the season's climate to keep the grain in good condition. As the old saying goes, "The valley is sunburned in autumn, and the warehouse is hidden in winter," observe the weather to protect the grain.

Third, during transportation, choose people who are good at driving boats and carriages. The boat must be sturdy, and the loading of the car and boat should not be too full to prevent overturning. And the itinerary is arranged, when there is a risk of wind and rain, choose the time according to the water conditions and road conditions. As mentioned in "Tiangong Kaiwu", "The water situation must be checked when traveling a boat, and the traffic must depend on the road conditions."

Fourth, above management, the accounts must be clear. The number of discrepancies should be recorded in detail to prevent criminals from stealing and corruptive practices. Special personnel are set up to supervise and check regularly, so that the amount of money and food is clear.

Fifth, prepare for the infestation of rats and insects. In the warehouse, install rat traps and rat poison, and keep the warehouse clean, so that rats and insects have no breeding place. For grain insect control, natural things, such as mugwort leaves, can be used to avoid insect damage.

All these things are important for the loss of money and grain storage, and they are related to the livelihood of the people under the world. Don't slack off a little.
