4-Fluoroisoquinoline

4 - The path used by the light in the river is important. This light has a special nature and is useful for all kinds of things.
Its primary use is in lighting. In the dark of night, the light in the river can break the mask of darkness, so that everything that shines is bright. Its light is soft and not dazzling, like the moonlight setting, and there is more separation. It provides clarity to those who walk at night, those who watch at night, and those who work in the dark, so that they can act safely, without being hindered or hindered by darkness.
Furthermore, the light in the river can be used for discrimination. Because of the things illuminated by its light,, is the text on the, is the reason on the utensil, can be clear. For those who use this light to write a book; For artisans, it can also be used to distinguish the coarseness of the utensil and the inferiority of the material, so as not to be judged.
In addition, Jiang Fang's light also has its use in the form. For sacrificial purposes, this light is used by the things of the gods, which can add to the atmosphere of Mu. Its light seems to be able to connect heaven and earth,, making it easier for the sacrificial mind to be used by the gods, praying for blessings and eliminating misery.
And because of its special nature, it can eliminate some evil things. In remote places, or where there are ghosts and ghosts, the river can be filled with light, which can make people feel safe and evil. This is not a lie, but the effect of the people, so that there are many people who use this light to keep their homes safe.
Moreover, the river light plays an important role in lighting, discrimination, style and warding off evil spirits. It is indispensable for people's lives and general actions.

In "Tiangong Kaiwu", it is said: "Where boron light is different, its properties are special, and there are many wonderful things." Boron light has unique physical properties.
One, its refractive properties are strange. When light enters the boron light material, it is different from ordinary matter. Ordinary light travels in a straight line or is deflected at a certain refractive angle. However, boron light can make light propagate in a special path inside, as if light is endowed with agility and meandering through it. This unique refractive property can be used to make delicate optical devices, such as special lenses, which can achieve extraordinary focusing and imaging effects.
Second, the polarization characteristics are special. Light has a state of polarization, and boron light has a unique effect on polarized light. It can selectively change the propagation characteristics of light in different polarization directions, just like setting special rules for light. It can be used to make polarizing devices, which is of great significance in the field of optical communication and display. For example, in high-end display screens, this feature can be used to improve image contrast and color reproduction, making the picture more realistic and gorgeous.
Third, the luminous properties are wonderful. Excited by the outside world, boron different square light can emit unique light. Or it is a brilliant color, or it has a special luminous intensity and lifespan. In the field of lighting, new light sources can be developed to provide soft and efficient lighting; in the field of biological imaging, it can be used as fluorescent markers, with its unique luminescence, accurately marking biomolecules, helping scientists to understand the mysteries of the microscopic biological world. Due to its unique physical properties such as refraction, polarization, and luminescence, the

boron heteroscale light has shown great application potential in many fields, which needs to be further explored and tapped by the world.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. Its text is simple and concise. Today, in its style, it discusses the chemical properties of Jiangyifang Guang (suspected to be "Jiangyifang Stone" and the like, assumed to be a special ore).
Jiangyifang Guang is often born in Jiangzhu rocks. Its color is blue and purple, and its luster is introverted, not shining. Touch it, the quality is firm and cool, like holding ice jade.
It is in the fire, and it changes when exposed to high temperature. At first, only sparks are slightly flared, and it seems unwilling to transform into this. And the fire is getting hotter, but it gradually melts, like spring ice meets warm sun. At this time, a strange aura was emitted, smelling it, slightly eerie, but there was a faint fragrance of grass and trees, like water and fire, giving birth to a different aura.
Tested with acid, the reaction was slow at first, and after a long time, fine bubbles gushed out, like the beginning of a spring, gurgling endlessly. The bubbles gradually increased, and the surface of the river's different light seemed to ripple, and then slowly melted, turning into a liquid, its color turned light green, and it was a little hazy in the clarity, like new leaves soaked in clear dew in spring.
If they encountered alkali, the two touched, and in an instant, there was a hissing sound, like a dragon singing in the abyss. Then, a white flocculent is born, floating in it, like a white cloud drifting, and this thing gradually condenses, eventually forming a hard block, indestructible, radiant in color, suet-like jade.
It is co-located with the metal, and may change strangely over time. Combined with copper, it can turn the copper color red, and the texture is firmer, like iron and stone, anti-corrosion and wear-resistant; when it encounters iron, the iron surface is colorful, glowing blue light, like a brocade robe, but its properties also change, and the flexibility is slightly increased, not as hard as before.
Jiang Yifang has unique photochemical properties and varies widely between water, fire, acid and alkali. It is a wonder of creation in heaven and earth. If it is well explored and utilized, it will definitely add a lot of help to the industries of engineering, medicine and utensils.

The ancient skilled craftsmen often used the principles of heaven and earth and nature to seek materials and techniques, so as to achieve their wonderful effects in light.
One of them is the most important material. If you want to get 4 square lights, or take precious stone jade, because it is the essence of heaven and earth, the earth and the light are transparent, and it can produce fantasy light and shadow. Such as the jade of Kun, its color is not good, and the tool of carving is placed under light, the light is refracted and the color is not good, or it can be close to the effect of 4 square lights. Or the natural crystal, some crystals are special, and the light has a special effect. To be refined, it is also a good material.
Second, the carving technique. The craftsman handles the knife, according to the shape and shape of the material, carefully. If it is jade, or relief, or empty space, the light will be on the concave and convex, and there will be different directions. The relief of the sculpture, the light will gather and reflect, and the gap of the void, the light will penetrate and penetrate, and the ingenious layout can make the light show a specific shape, and the environment of 4-square light. For the crystal, the polishing work is also good. According to the direction of the crystal, the center is polished, and the refraction angle of the whole light is refined, so that the light will be emitted, and it will be the desired light effect.
Third, use other things. Or use glass, colored stones and other things, and match the main materials. The color of glass is rich, and it can be used to make light and color. The color of colored stones is special, and it can shadow and scatter light. The two want to synthesize 4-square light materials together. In a specific arrangement and embedding method, light can be used by different materials to generate wonderful light, so as to make the 4-square light visible.
Fourth, by the power of nature. The ancients often used to observe celestial phenomena and observe the four, and use specific materials and places to make materials illuminated by nature. For example, when the sun rises in the morning and falls in the west at night, the light is soft and the angle is special. If the object to be synthesized is placed in the open air, it may be washed by the light of the sun, or it can lead to the transformation of the material, so as to promote the effect of the light. Or in special places such as mountains and caves, due to different factors such as temperature, current, geomagnetism, etc., the light has a special shadow, and the light material is placed in it, and it may also have a 4-10 square light-like effect for 7 days.
Of course, synthesizing 4-10 square light requires craftsmen to figure out carefully, and there are many factors such as materials, technology, heat, and land to achieve success.

The price of tetradeuterium isoamyl ether is between twenty-five gold and thirty-five gold per Dendrobium in today's market. The price fluctuates because of changes in supply and demand, and differences in the quality of the craftsmanship.
If there are many seekers in the market, but the number of products is small, the price will go up; on the contrary, if there are few seekers and many products, the price will go down. And those with excellent craftsmanship have high quality and high price; if the system is not good, the quality will be at a loss, and the price will be low.
Merchants who sell this light observe the movement of the market, judge the situation, and seek a good price. Its price is uncertain, often varies with time, or varies with geographical location. However, in general, the price of twenty-five to thirty-five gold per Dendrobium is the norm in the city. Those who buy and sell are based on this price and negotiate transactions for mutual benefit.
