Benzene 1 3 5 Trifluoro 2 4 6 Triiodo

The chemical properties of 1,3,5-triene and 2,4,6-triazine are related to many chemical principles.
1,3,5-triene has an unsaturated carbon-carbon double bond structure. This double bond is active in nature and can often participate in addition reactions. Due to the high electron cloud density of the double bond, it is vulnerable to attack by electrophilic reagents. For example, when encountering hydrogen halide, the positively charged hydrogen atom in the hydrogen halide first binds to one end of the double bond to form a carbon positive ion intermediate, and then the halogen ion binds to it to complete the addition and obtain the corresponding halogenated hydrocarbon. In the presence of a catalyst, it can be added to hydrogen to convert double bonds into single bonds to obtain saturated hydrocarbons. At the same time, 1,3,5-triene can also undergo polymerization. Under suitable conditions, many triene molecules are connected to each other to form high-molecular polymers, which is very important in the field of material synthesis.
As for 2,4,6-triazine, its molecular structure contains nitrogen heterocycles. The nitrogen atom has a lone pair of electrons, making the ring appear certain alkaline. It can react with acids, and the nitrogen atom accepts protons to form salts. Moreover, the substitution reaction on the 2,4,6-triazine ring is also characteristic. Due to the electronic effect of the nitrogen atom, the reactivity at different positions on the ring is different. In the nucleophilic substitution reaction, specific reagents can attack the appropriate position on the ring to achieve the substitution of groups, and then synthesize various compounds containing triazine structures. This structure is widely used in pesticides, medicine and other fields, because it can impart specific biological activities to the compounds by modifying its substituents.
In short, 1,3,5-triene shows its characteristics through the addition and polymerization of unsaturated double bonds, while 2,4,6-triazine exhibits unique chemical properties due to the alkaline and substitution reactions of nitrogen heterocycles. Both are of great significance in many branches of chemistry and have made great contributions to the synthesis of new substances and the exploration of new materials.

The "Three Rivers" represented by 1% 2C3% 2C5 and the "Triassic Spring" represented by 2% 2C4% 2C6 have different physical properties.
Let's talk about the "Three Rivers" first. Its water flow is turbulent, the water volume is huge, and it is majestic. The physical characteristics of water are mainly based on fluidity. It depends on the terrain drop, or turbulent, or meandering, and it goes forward without a change. And because it carries a lot of sediment and other substances, its density and viscosity also change. In terms of temperature, it is greatly affected by the region and season. The water temperature may be higher in summer, and it may cool down significantly in winter, or even freeze and freeze. In addition, the speed of water flow varies significantly in different river sections. The upstream water is turbulent and the kinetic energy is strong; the downstream terrain is flat, the flow speed is slow, the kinetic energy is gradually weakened and the potential energy is also reduced.
As for the "Triassic Spring", it is unique. The spring water falls from the height layer by layer, forming a wonderful landscape. In terms of physical properties, the spring water is relatively clear, contains less impurities, and the water quality is pure. Its temperature is relatively stable, mostly originates from the deep underground, and is less affected by changes in surface temperature. The temperature difference between the four seasons is not large. In terms of flow characteristics, although it is also flowing water, during the falling process, due to the action of gravity, a unique water flow pattern is formed. Each stack has a different drop, and the impact force and speed of the water flow are also different. It produces different degrees of water splashing in the air, and the sound is crisp and pleasant, which is very different from the majestic water flow of the "Three Rivers". And because the water flow disperses and falls, the contact area with the air increases, and the amount of dissolved oxygen in the water may be more abundant than that of the "Three Rivers".
In short, the "Three Rivers" and the "Three Rivers Spring" show distinct differences in physical properties, such as water quality, temperature, flow state, and interaction with air, and each has a unique physical charm.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, which contains many crafts and technologies in detail. In ancient Chinese, the answer to this question is as follows:
If you want to make a scene of the three pools of the printing moon, first look at the place. The three pools of the printing moon are located in the West Lake. If you want to imitate it, you need to find a place with a vast lake and shimmering water waves. The water should be clear and quiet before it can reflect the beautiful shadow.
As for the construction of the pool, the stone should be selected. The texture of the stone should be firm to prevent damage caused by erosion and water waves initializing. After taking the stone, carve it according to the shape of the design. The shape of the pool is better when it is in the shape of a gourd. This shape is simple and beautiful, and it is in line with feng shui. When carving, the craftsman needs to be meticulous and precise in the knife technique to make the lines of the pool smooth and natural.
When the pool is completed, place it in the right position in the lake. The three pools are distributed in an equilateral triangle, and the distance between the pools should be uniform, so as to create a symmetrical and harmonious beauty. When placing the pool, it is necessary to ensure that it is stable, buried deep in the mud at the bottom of the lake, or reinforced with the help of cornerstones, so that the pool can be safe in the wind and waves.
In addition, holes are placed on the pool. The number, size and position of the holes are all exquisite. There are seven holes in each pool, with a total of twenty holes. On the night of the full moon, the holes can reflect the moon, and they can reflect the moon in the sky, forming a wonder of "the moon in the middle of the moon". The size of the holes should be able to penetrate the moonlight and form a clear moon shadow, and the positions should be scattered and not messy.
In this way, after site selection, stone selection, carving, placement, hole placement and other processes, it can be made to resemble the scenery of the three pools printing the moon, and its charming style can be reproduced.

Looking at the arrangement of these numbers, 1, 3, 5 and 2, 4, and 6 are divided into two groups. The former should be related to the rivers, lakes and seas, and the place where the "Three Pools Yinyue" is located is often a watery resort.
"Three Pools Yinyue" is famous in the West Lake. The West Lake is a famous lake in the world, with water colors and mountains, which complement each other. There are many water pavilions and pavilions in its place, and scholars and writers often gather here to recite poems and leave many good stories.
In the field of water conservancy and irrigation, where the water network intersects, such as the water towns in the south of the Yangtze River, many lakes and canals nourish all things, the "Three Pools Yinyue" is located around the West Lake, which is convenient for water conservancy and irrigates fertile fields, so that people can have enough food and clothing.
In the field of boat shipping, although the West Lake is not like a river that can accommodate huge ships, it is also one of the scenes of shipping.
In terms of landscape tours, the "Three Pools Yinyue" is even more of a landmark landscape of the West Lake. On the night of the Mid-Autumn Festival, the moonlight shines on the pond, and the tower shadow, moon shadow, and cloud shadow melt into a lake, like a dream, attracting countless tourists to come and watch this wonder.
Furthermore, in the field of cultural inheritance, poems, songs, and legends related to the "Three Pools Yinyue" have been passed down through the ages, adding luster to Chinese culture and enabling future generations to appreciate the elegance and talents of the ancients.
In summary, the rivers, lakes and seas associated with 1, 3, and 5, and the "Three Pools Yinyue" involved in 2, 4, and 6 have their unique functions and significance in many fields such as water conservancy irrigation, boat shipping, landscape tourism, and cultural inheritance.

The first, third, and fifth people are the genus of the positive number, and their nature is strong and vigorous. They are also in the city. If they are brave and resolute, they are enterprising and fearless. They are often the vanguard of the city, expanding new territories, creating business opportunities, being bold and decisive, and acting with many pioneering abilities.
As for the second, fourth, and sixth people, the negative number and the like, their nature is supple, and they are like calm business in the city. They plan to move later, observe the slight changes in the city, be careful in action and careful in thinking, be good at keeping the existing karma, and seek progress when the times change.
However, the market is impermanent, and the mutual assistance of yin and yang is a long-term way. Although the generation of positive numbers is brave, if they move forward rashly regardless of the current situation, they may be frustrated; although the flow of negative numbers is stable, if they are too conservative and miss the opportunity, it will be difficult to make a big deal.
Taking the Three Kingdoms as an example, Cao Cao is like the number of yang, his power is fierce, chasing the central plains, forging ahead with determination, recruiting talents, and wanting to become hegemony. Liu Bei, on the other hand, had a weak foundation at the beginning, such as negative numbers, temporarily living under people, accumulating strength, and leaving when the time comes. Later, he obtained Zhuge, borrowed Jingzhou, Tuyizhou, and gradually became a powerful force.
Therefore, in today's market, the masculine should know how to converge at the right time and judge the situation; the feminine should be decisive and attack at the right time. The two complement each other in order to gain market opportunities, seek long-term benefits, and achieve great success in the unpredictable market.
