1 - What are the main uses of wood?

Wood, the use of wood. The gallops produced on it are important raw materials for use and labor. Gallops contain a large amount of oil. In terms of food, they can be collected, hemostasis, detoxification, and have effects on many diseases. In terms of labor, they can be used in tanning leather, ink, dyes and other fields, which can make leather and dyes add color.
Its skin and root bark can also be added to the skin, which has the functions of clearing and detoxifying, dispersing blood stasis and stopping bleeding. In case of bruises, hemorrhage in the stool, hemoptysis, etc., they can be used to solve the problem.
The flower of the wood, the rich nectar, and the good nectar source plants can attract bees to collect honey and help the development of the bee's work.
Furthermore, the quality of the wood, the root system, can fix the soil and retain water, and plays a role in soil and water conservation. It can prevent soil intrusion and balance the growth. Its branches are lush and can be used in forestry, adding to the beauty of natural scenery. And its fruit can attract other things, which is beneficial to the biodiversity. In addition, the wood has important value in many aspects such as use, engineering, and hygiene.

It is strong and dense, its color is silvery white, and it has a hint of luster, just like the pouring of the moon, restrained and charming. When you touch it, you can feel the coolness in your hands, as if ice and snow are melting at the beginning, and the chill is through your bones.
Looking at its physical characteristics, the melting point is quite high, and it is difficult to melt it without burning fire. It is like a stubborn stone that keeps its resolve and does not move. When it reaches the melting point, it turns into a liquid, flowing like a galaxy, and it is very agile. Its boiling point is also high. To vaporize it, you need extremely hot energy. This is its stability.
The density of potassium boron halide is larger than that of ordinary metals. When held in the palm of your hand, it feels quite heavy, as if it contains the thickness of the earth and carries the quality of all things. Its conductivity is good, the current passes through it, and it travels unimpeded, just like a horse galloping on a smooth road, without any obstacles. In the magnetic field, it also has unique responses, or it can conduct magnetism, or it can generate electricity, and the changes are wonderful, like a mysterious machine.
Its ductility cannot be underestimated, it can be beaten into thin sheets, as thin as cicada wings, and it can transmit light to reveal a magnificent color, which is beautiful. It can also be drawn into silk, which is slender and flexible, like spider silk in the air, swaying and constantly swaying in the wind, and is both rigid and soft. This variety of physical properties makes potassium boron halide useful in various processes and equipment, which can contribute to the country's important tools and help people's livelihood thrive.

The chemical properties of potassium halide are very different and interesting. Boron is non-metallic. It combines with halogen elements and potassium in potassium halide, resulting in a unique chemical behavior.
Potassium halide reacts with water. Water is a common solvent, and its molecules are polar. In potassium halide, the bond between boron and halogen atoms may be broken due to the action of water. The electronic configuration of boron is\ (1s ^ {2} 2s ^ {2} 2p ^ {1}\), which is characterized by electron deficiency and is vulnerable to attack by lone pairs of electrons on oxygen atoms in water molecules. The halogen atom, depending on its type, or the halogen ion is free in water. If potassium boron chloride encounters water, boron or reacts with water to form boric acid substances, chlorine forms chloride ions, and the intensity of the reaction depends on the specific composition and reaction conditions of potassium boron halogen.
Under the action of heat, potassium boron halogen also changes. High temperature can intensify the vibration of the chemical bonds in it, causing the bond to break and recombine. The binding force between boron and halogen atoms and potassium atoms may be destroyed, and the atoms are rearranged to form new compounds. In this process, there may be gas escape or solid phase changes.
And potassium boron halogen also exhibits in redox reactions. Although boron has many positive valence, under certain conditions, it may be able to obtain electrons and be reduced. In the halogen atom, fluorine has extremely strong oxidizing properties, and in the potassium halide, it may change the valence states of boron and potassium. Potassium is an active metal and is prone to losing electrons. In the potassium halide system, it also affects the overall redox properties.
The reaction of potassium halide with acid and base is also an important aspect of its chemical properties. In an acidic environment, protons may interact with certain atoms in potassium halide to change its structure and composition. In an alkaline environment, hydroxide ions may participate in the reaction to decompose or convert potassium halide into other substances. In short, the chemical properties of potassium halide are determined by its atomic composition, structure and external conditions, and it is worth exploring in depth.

The method of mercury, the ancient method is now. The ancient method of mercury, mostly from Dan sand.
In the case of Dan sand, the mercury sulfide is also red and bright. The method is to first take the Dan sand and place it in a dense vessel, and the "tripod" of this vessel is also "". The tripod is mostly made of clay or gold, and it is dense to prevent the escape of mercury.
The Dan sand is put into the tripod, and it is calcined by fire. The degree of fire is controlled by the grid. If the degree is low, the Dan sand can be decomposed; if the degree is high, the mercury or other substances can be collected quickly. With the slow addition of charcoal fire, the dansand is decomposed by heat, and the reverse reason is that because the mercury sulfide encounters high heat, the sulfur and mercury phase are reduced. Sulfur and oxygen are combined, and the sulfur dioxide of the sulfide escapes, and the mercury is reduced to the tripod.
The mercury that is reduced is condensed into the liquid when it encounters the cold wall of the tripod. The ancients or made a special process to make the mercury flow down the wall, and collect it at the bottom of the tripod or in the container. The mercury collected, or again, to remove the waste. The method of lifting the waste is also to steam it, and use a suitable device to add the mercury liquid, the mercury will rise, and the mercury will be condensed to obtain mercury.
In addition, in ancient times, there were also mercury-containing substances, but they all used similar chemical principles, or calcination, or other chemical reactions, to precipitate mercury, and then collect and extract it. The method of operation varies depending on the temperature, the place, and the materials used. However, it is necessary to obtain mercury for the purpose of mercury, and skilled skills are required to obtain mercury.

When storing and raising Tibetan bees, you need to pay attention to many matters.
First, check the territory of the place where they are kept. Tibetan bees are suitable for keeping in a place with high altitude, cool climate, and rich and clean honey sources. The mountains and rivers are beautiful, free of pollution and disturbance, and the top choice is the best. The nectar source plants here are diverse, and the flowering period is shared, which can preserve the bee food source. And the environment is quiet, without the hustle and bustle of cars and horses, and the disturbance of people and animals, Tibetan bees can make honey in their nests with peace of mind.
Second, choose beehives carefully. The material of the hive should be solid, durable, and breathable. Its shape should be suitable for the habits of Tibetan bees, and the size is accurate, which is conducive to the colony settlement. The quality of the nest spleen is related to the reproduction And the tool for taking honey must be clean and sterile, so as not to contaminate the honey and damage its quality.
Third, take good care of the bee colony. It is important to observe the state of the bee colony, and observe its frequent entry and exit, the health of the queen bee, and the increase and decrease of the colony momentum. Expand and and shrink the nest in a timely manner to respond to changes in the number of bees. When the flowering period is at its peak, it helps the bees to collect honey. When there is a lack of honey, it should be suitable for supplementary feeding. And to prevent the invasion of diseases, always check the bee colony, and know what you see. It changes according to the season, to adjust the temperature and moisturize the bee colony, to prevent heat in summer, and to keep out the cold in winter.
Fourth, the way to re-harvest honey. When collecting honey, choose a good day According to the honey source and the condition of the bee colony, determine the amount of honey to be collected, keep enough bee food, and keep the bee colony alive. The honey after harvest should be processed quickly to prevent deterioration, so as to maintain its pure flavor and nutrition. In this way, Tibetan bees can be properly cared for during storage and transportation, and the bee industry can thrive.
