The praseodymium-neodymium variant light is widely used, and it is of great benefit to all kinds of craftsmanship.
First, in the industry of smelting, the praseodymium-neodymium variant light can help to detect the quality of the casting. The ancient casting tools, in order to seek their firmness and refinement, often rely on this light to observe their inner flaws. Those who observe the casting of swords, using the praseodymium-neodymium variant light, can see that the texture of the sword body is dense, and if there are hidden cracks and dark wounds, they will not be hidden. This light can penetrate the interior of the casting, so that good workers can adjust the casting method according to their feelings, or increase the heat, or change the ingredients, so that the casting can be perfect.
Second, in the art of weaving and embroidery The silk is woven, and before the embroiderer applies the needle, the praseodymium and neodymium are illuminated in different directions, which can show the evenness of the silk strands. The silk has uneven thickness and different twists, and it is clear at a glance through this light. The embroiderer can use this light to distinguish the advantages and disadvantages of the silk, and choose the silk color scheme to make the embroidery color harmonious and the stitching uniform. And this light also has a great effect on inspecting the quality of the embroidery after completion. It can be seen that the density of the stitches, the connection of the silk threads, and whether there are off-threads or leaks of embroidery can be clearly presented.
Third, in the technique of pottery, the purity of the clay can be tested by the different light of praseodymium and neodymium. When the potter returns from mining, the soil sample is illuminated If there are too many miscellaneous stones and gravel, the method of washing and screening can be carried out in advance. When firing, use light to check the dryness of the pottery billet, and adjust the kiln temperature in a timely manner to make the texture of the pottery uniform, so as not to break due to uneven dryness and dampness. After leaving the kiln, this light can be used to check the flatness of the surface of the pottery and the uniformity of the glaze color, and help the potter to judge the grade of the utensils.
Fourth, in the construction of the work, praseodymium neodymium can measure the toughness of the wood. To build palaces and bridges, it is necessary to choose materials. The craftsman takes the wood and uses light to detect its texture to see if it has the appearance of moth-eaten or decayed. If the heart of the wood is decayed and the appearance is difficult to distinguish, This can ensure that the wood is solid and usable, so as to avoid the danger of collapse of the things created in the future. And in the selection of masonry materials, this light can also help the craftsman to distinguish its texture and make the foundation stable.

The physical properties of nitrocite are particularly good. This light originates from the interaction between the special structure and composition of nitrocite.
First of all, the color of nitrocite is often gorgeous, or like the green of fireflies, or like the red of the morning glow, the radiance is scattered and beautiful. This color is not a common light color in nature, because the elements in the stone are excited under special conditions, and the electron transition produces this special light color.
Furthermore, on its light intensity. The light intensity of nitrocite is not the same, either bright or dark, depending on the external conditions and the amount of composition in the stone. In the dark, its light can be visible, although not dazzling, it is enough to attract attention. And this light is not constant, or flickering, like the blink of a star, the mechanism of which is caused by the unstable release of energy in the stone.
And its light quality. This light is invisible to the touch, but it can be felt. Its quality is soft, unlike the scorching eyes of the scorching sun, nor the strangeness of phosphorous fire. When the viewer sees it, he often feels that the mind is calm, just like the power of peace in light. This feeling of softness is derived from the special combination of the frequency and amplitude of light, which interacts with the visual nerve of the human eye, resulting in this effect.
And nitrate stone light is penetrating. Although it cannot penetrate thick objects like sunlight, it can penetrate through thin objects or specific media, leaving light and shadow behind. This penetrating power is determined by the interaction between light and matter, which can cause atoms and molecules in some substances to vibrate, so as to achieve the effect of penetration.
In short, nitrocite has unique photophysical properties, and its color, strength, quality, and transparency are all extraordinary. It is a wonderful image between heaven and earth, waiting for everyone to explore in depth to solve the mystery.

Alum-based heterophosphors have unique chemical properties.
Alum-based heterophosphors often have strong oxidizing properties. In many chemical reactions, they can take away electrons from other substances and cause changes in their own valence states. For example, when they encounter reducing substances, they can promote oxidation and reduce themselves. This oxidizing property makes them a key reagent in some specific synthetic reactions, which can help to form new compounds and often exhibit efficient and selective reaction characteristics.
Furthermore, its stability is also characteristic. Under specific conditions, it can maintain the stability of the structure, and when it encounters suitable stimuli, such as changes in temperature, pH, or specific reactants, it can start a chemical reaction and exhibit active chemical activity. The unique structure endows it with sensitivity to different environmental factors, which makes the regulation of its chemical properties more flexible.
And the alum group is different in the acid-base environment, and the reaction tendency is also different. In acidic media, it may interact with certain acid ions to form a complex, and the formation of this complex may change the route and rate of chemical reactions. In an alkaline environment, it may react with hydroxide ions, etc., causing the rearrangement or decomposition of the structure, showing a chemical behavior that is completely different from that under acidic conditions.
And its photochemical properties cannot be underestimated. When irradiated by a specific wavelength of light, it may cause electronic transitions and the generation of excited states, which can promote a series of photochemical reactions. This photochemical activity makes it potentially useful in photocatalysis, photochromic and other fields. It can drive the occurrence of chemical reactions under light conditions and achieve specific chemical transformations.

The method of synthesizing mercury-based light is quite complicated, and in the past, there were many Fang families and warlocks who studied it carefully.
One method is based on all kinds of gold stones. First take Dan Sha, this is the raw ore of mercury, and its nature is pure yang. Put Dan Sha in a crucible and burn it slowly with charcoal fire. When Dan Sha is heated, it will separate, and the mercury gas will rise, and it will be carried by a condenser, so that pure mercury can be obtained. Then take a natural magnet, study it into a fine powder, and mix it with mercury. Place it in a cauldron and slowly refine it with a gentle fire. During this period, you need to keep the heat in place, so that it is not too much or too little. The properties of magnets can lead to the accumulation of mercury gas, and gradually change. When the color of the cauldron changes and the light fades, the preliminary synthesis can be obtained. < Br >
The second method is related to the combination of grass and trees and mercury. Find the spiritual grass comfrey, its color is purple and red, and it has the effect of activating meridians and harmonizing yin and yang. Take the stems and leaves of comfrey, juice and filter it. Pour the mercury into the comfrey juice, stir well. Then bury it in the soil, more than three feet into the soil. After ten days, take out the observation, the mercury has been mixed with the comfrey juice. Then use mulberry firewood as a fire to calcinate the mixture. The fire of mulberry firewood is mild, which can make the mercury and the nature of comfrey conform, and slowly form the embryonic form of mercury-based heteroscale light.
The third method is more strange, which is related to the weather and phenology. On a midsummer night, when the stars are shining brightly, put mercury on a jade plate in the open sky. The jade plate absorbs the moonlight, and the mercury is also cared for by it. When the night dew falls, dip it on the mercury. Before sunrise, collect the mercury liquid. Compound with realgar and orpiment powder and mix it with mercury. Realgar and orpiment are both sulfur-containing substances, and when they meet mercury, they can cause it to undergo wonderful changes. Seal this mixture in a lead box and hide it in a secret room for seven, seven, forty-nine days. Only then can this mercury-based square light be obtained, and its light is strange, or it can be used for various wonders.

When using gallium-based heteroscale light, all kinds of precautions must be paid attention to.
The first to bear the brunt is the consideration of the environment. Gallium-based heteroscale light is sensitive to changes in temperature and humidity. If the temperature is high, its performance may be variable, and if it is wet, it may be damaged. Therefore, the place used should be kept at constant temperature and humidity, and it should be protected from hot flashes, so as to ensure the stability of its performance.
Furthermore, when operating, the method must be cautious. Gallium-based heteroscale light is made of delicate material, and it is easy to damage if the external force is slightly increased. When taking and placing, it must be handled with care, do not apply force, and avoid touching with hard objects to prevent scratching and wear, and damage its light
Also, cleaning and maintenance is also the key. Dust and filth attached to it will hinder its luminous effect. However, when cleaning, do not use strong lotions, when gently wiping with a gentle thing, so as not to damage the special structure of its surface.
In addition, power supply adaptation should not be underestimated. Gallium-based heteroscale light has strict requirements on the stability of the power supply. If the current and voltage fluctuate too much, it can shorten the lifespan and even cause immediate damage. An appropriate power supply and a voltage regulator must be used to ensure the stability of the power supply.
At the end, storage is also important. When idle, it should be placed in a dry, cool and electromagnetic-free place. Electromagnetic interference or disorder of its internal structure, affecting future use.
All of these are what should be paid attention to when using gallium-based different square light. Those who use it must be carefully observed and practiced in order to maximize its effectiveness and prolong its lifespan.
