3-Jiang-4-Hai-1-Mackerers have a supple nature and can weave good songs. They live at the junction of rivers and seas, and their things are used for many purposes, which are beneficial for all kinds of matters.
The silk woven by mackerers is as thin as the wings of a cicada, as light as smoke, and does not get wet when it enters the water. It is extremely precious. This silk is in the world, and can be used to make clothes for officials and nobles. It is graceful and luxurious, and has the ability to avoid water. It can go up in the water without getting wet. It can also be used to make armor for warriors. It is light and tough. It can resist swords, guns and arrows, and protect people's bodies.
The song of mackerers is melodious and touching. Its sound can attract hundreds of fish to the dynasty and calm the waves. In times of war at sea, mermaids' songs can disrupt the hearts of the enemy's army and make their positions in chaos; in boats on the sea, in times of storms, mermaids' songs can soothe the wind and waves and keep the boat safe.
The mermaids are sobbing and crying, but they can become pearls. The pearls are round and bright, with dazzling light, and have the effect of healing injuries and diseases. For those who are injured and sick, hold the pearls close to the body, and the pain will gradually disappear; they can also ward off evil spirits in the house and put them in the house. All evil spirits will not invade, and the house will be peaceful.
And the mermaids are familiar with the paths of rivers and seas, and know where there are rare treasures and where to hide dangerous reefs. If there are people who sail, they can get the help of the mermaids, and they can ensure a smooth journey and obtain endless treasures
Therefore, the 3-Jiang-4-Hai-1-Mackerel, his skin, his song, the pearl of his tears, and his knowledge of the river and the sea are all rare aids in the world. They are of great use in many aspects such as clothing, war, navigation, healing, warding off evil spirits, and are valued by the world.

3-Jiang-4-Hai-1-Jingwei's quality is very different, each has a wonderful theory, detailed as left.
Its shape is also, river water soup soup, vast galloping, or detouring between the mountains, or flowing over the flat field, like a dragon walking on the earth, majestic. The sea water is boundless, the waves are turbulent, and it is dazed and connected with the sky. Its vastness is awe-inspiring. Jingshui and Weishui, one turbid and one clear, are distinct and distinct, like the outline of a divine stroke of creation, with unique wonders.
As for its color, the river water is often green and blue, which changes with the seasons. In spring and summer, it is full of green; in autumn and winter, the color turns dark. The seawater is mostly blue, and when viewed from a distance, it is like a gem paved, and when viewed from a close distance, it is also changed by light and shadow, and it is colorful. Jingshui is turbid and earthy yellow, Weishui is clear and white, and the intersection of the two is clear and yellow-white, which is a wonder.
The difference in taste is also very significant. The taste of river water is clear and slightly sweet, because it merges the essence of mountains and rivers in the place it passes through, so it has a unique flavor. The seawater is abnormally salty, which is caused by the fact that it contains a lot of salt. Although the water of Jingwei originates from mountain springs, it carries more sediment and sand, and the taste is slightly muddy; Weishui is relatively clear and has a lighter taste.
Its nature is also different. The river water is lively and lively, galloping endlessly, moving forward all the way, unstoppable, and seems to have an enterprising heart. The sea water is deep and tolerant, Nabai River does not refuse, calm when calm, violent when angry, full of majesty and grandeur. Jingshui is turbulent, due to the drop in terrain, the water flow is rapid; Weishui is gentle, flowing leisurely, and has its own calm state.
Looking at this 3-River-4-Sea-1-Jingwei, each with its own physical properties, or galloping, or vast, or clear and turbid, it is a masterpiece of creation in heaven and earth, which is breathtaking, feels the magic of nature, and understands the wonders of all things.

There are various ways to synthesize 3-ene-4-alkyne-1-bromonaphthalene.
One can be initiated by naphthalene derivatives, and bromine atoms are introduced at specific positions in the naphthalene ring. Commonly used brominating reagents, such as liquid bromine, are catalyzed by suitable catalysts (such as iron powder, etc.) through electrophilic substitution to connect bromine atoms to the naphthalene ring. Subsequently, alkenyl groups and alkynyl groups are introduced. The alkenyl groups can be reacted with metal-organic reagents (such as Grignard reagents) by halogenated hydrocarbons and metal-organic reagents (such as Grignard reagents) through a series of transformations to form carbon-carbon double bonds in the molecule. The introduction of alkynyl groups can be obtained by nucleophilic sub In this way, the synthesis of 3-ene-4-alkyne-1-bromonaphthalene can be gradually achieved.
Furthermore, the coupling reaction between the compound with the alkyne structure and the bromonaphthalene-containing structure fragment can be considered. For example, the coupling reaction catalyzed by palladium, such as Suzuki (Suzuki) coupling, Heck (Heck) coupling, etc. The borate or halogenated alkyne containing alkyne and the halogen or trifluoromethanesulfonate containing bromonaphthalene, etc., under the action of palladium catalyst, ligand and base, the formation of carbon-carbon bonds can be achieved, so as to obtain the target product. This method has good selectivity and relatively mild conditions, which can effectively avoid the occurrence of some side reactions.
In addition, starting from the selection and design of raw materials, starting materials with suitable functional groups can be found that are easy to convert. Through the gradual conversion and modification of the starting functional groups, such as the halogenation of alcohol hydroxyl groups into bromine atoms, and then the elimination reaction and addition reaction to construct the alkyne structure, and then synthesize 3-ene-4-alkyne-1-bromonaphthalene. This process requires precise control of the reaction conditions, and rational selection of solvents, temperatures, catalysts, etc. according to different reaction characteristics to ensure the smooth progress of each step of the reaction and improve the yield and purity of the product.

3-4-Sea-1-Finless porpoises, when it comes to conservation and transmission, all people should pay attention.
The protection of the environment is the first priority. The quality of its water is the key. If the water is dirty, it is difficult for the dolphin to survive. Rivers, lakes and seas should be kept clear, free from filth and poison. Waste from industry and pollution from life must be strictly controlled and carefully discharged, so as not to invade the dolphin's residence.
Secondary inspection of temperature and flow pattern. Dolphins are suitable for specific water temperature and water flow environment. Changes in climate can cause abnormal water temperature, and the flow rate and direction of water may also change. This is all related to the survival of the dolphin, and must be carefully observed and warned, so as to be unpredictable.
Furthermore, during the transmission, one should avoid disturbances. Dolphins are sensitive to noise and strong light, which can make them fearful. The sound of cars and boats and the brilliance of lights should be reduced to a minimum. The device of transportation should also be suitable for the body of the dolphin, spacious and comfortable, and ensure its peace.
Again, on the occasion of handover, the procedures must be clear. Everyone should abide by the rules and regulations, and do not make omissions. And the method of transmission and protection should be new with the world, and according to the nature and condition of the dolphin, better policies should be developed.
Also, it is always a priority to observe the state of the dolphin. Its food, movement and rest should be paid attention. If there is a slight abnormality, seek medical treatment quickly, and do not let the disease harm the dolphin.
In short, to protect and transmit the 3-4-sea-1-finless porpoise, everyone should be in awe, cautious, and do their part to ensure the prosperity of the porpoise, so that this spiritual creature can live forever between heaven and earth.

The impact of 3-4-gas-1-bromofluoride on the environment and human body is related to people's livelihood and cannot be ignored.
Bromine can diffuse in the environment through various channels. If it exists in the atmosphere or drifts with airflow, it affects a wide area. Descending in water bodies can cause water quality variation and endanger the habitat of aquatic organisms. Aquatic organisms are damaged by bromine, or their growth is blocked, or their reproduction is inhibited, and the ecological chain is also damaged. And the accumulation of bromine in soil will change soil properties, affect the uptake of nutrients by plant roots, and then affect vegetation growth.
Fluorine also has a significant impact in the environment. If fluoride in the atmosphere exceeds the standard, it can enter the human body with respiration and damage the mucosa of the respiratory tract. In soil, excessive fluoride can cause soil compaction, reduce fertility, and reduce crop yield. Plants are contaminated with fluoride, and leaves often appear damaged, which affects photosynthesis and reduces crop quality.
As for the human body, if too much bromine is ingested, it can disrupt the nervous system of the human body. Light or cause headache, fatigue, insomnia, or affect cognitive and behavioral ability. Bromine may also interfere with the human endocrine system and affect hormone balance.
The impact of fluoride on the human body should not be underestimated. Moderate fluoride is good for dental and bone health, but excessive intake can easily lead to dental fluorosis, and even bone fluorosis. Bone pain and deformation in patients with skeletal fluorosis seriously affect their ability to live and work.
Therefore, 3-4-gas-1-bromo fluoride has a great impact on the environment and human body. It should be treated with caution to prevent its pollution and protect the environment and human safety.
