Reaction of Red Phosphorus and IsopropvlThe reaction of red phosphorus with potassium alcohol was a substitution reaction, and the reaction formula was CH3- CH(SH) -CH3 +I2(P)→ CH3-CHI-CH3 +HOI, where P13 was the catalyst. In addition, the red phosphorus was mixed evenly with the alcohol, placed in a ball mill tank, and ball-grinded under a protective atmosphere, then washed with alcohol and dried to obtain the ball-grinded red phosphorus.

Film Formation by the Reaction of Poly (Glylene Glylene) and IsocyanateThe reaction of polygly lene with an amine could produce a linear high molecular weight. In the cross-linking reaction system related to water-borne pu dispersion, the amine group was a highly reactive functional group that could react with a variety of active hydrogen containing compounds (such as the hydrogen group in the polygly lene).
For example, in the preparation of certain materials, similar reactions may be involved. The reaction process may occur under certain conditions, such as a specific temperature, a suitable catalyst, and so on. These reaction products could be used to construct various functional and biological materials, but there was no direct indication that this reaction would directly form a film. From the perspective of some preparation processes, a series of complicated reaction steps, including mixing with other substances, reacting, adjusting the pH-value, etc., were used to obtain products with film properties such as protective paint.
Therefore, although the reaction of polygly lene glyols and potassium cyanates could produce a linear high molecular weight, there was no clear and singular description of the process and conditions for the direct reaction to form a film. It may require more reaction conditions, additional materials, and subsequent processing steps to form a film.

The film mainly reflected the following aspects:
1. The historical and cultural background of China's rural areas: The film reflects the history and culture of China's rural areas, including traditional agricultural economy, social structure, values, etc.
2. The impact of war and famine: The film described the impact of war and famine on China's rural areas, including the fate and living conditions of families, villages, and farmers.
3. The influence of political turmoil: The film portrays the impact of political turmoil on rural areas, including government policies, religious beliefs, social class division, etc.
4. The presentation of human nature and human feelings: The film portrayed the complexity of human feelings and human nature, including kinship, friendship, love, etc., by showing the emotional entanglements and human nature between family members.

There was no reaction from the red dots on his bodyIf there are small red spots on the body and there is no reaction, it may be a cherry-like hemomaly, commonly known as "red mole" and "senile hemomaly". It is mostly caused by the local capillaries of the skin. It is usually a manifestation of skin aging. The appearance of young people may be related to hormonal changes.(For example, pregnant women and people with high mental stress). It is not harmful to health and does not require special care. Pay attention to sun protection and avoid rubbing and scratching. If it affects the appearance, you can go to the Dermatology Department of a regular hospital to remove it by laser, freezing or electrocoagulation.
However, there were other possibilities. For example, spider moles often appear on the neck and chest. There are red blood vessels around the red spots. When the red spots and red blood vessels disappear when pressing, they appear after releasing the hand. This may indicate that the liver function is damaged. The liver cannot regulate the body's estrogens, causing estrogens to accumulate in the body and stimulate the blood capillaries to swell and expand.(This may happen with chronic viral infections, liver cancer, and other diseases, but it is normal for adolescent girls and pregnant women to have spider moles due to increased levels of estrogens in their bodies. Don't worry, they will disappear with age or after giving birth.)
It could also be a needle-like bleeding point caused by a decrease in the number of blood capillaries and a problem with the blood clot function. This kind of bleeding point would easily turn into a large bruise after bumping into it. Other parts of the body such as gums, oral mucus, nasal cavity, etc. might also bleed abnormally. In addition, viral infections (such as infant rash, chickenella, rubella, measles, etc.) may also appear as red spots on the body in individual cases, but it is generally accompanied by a certain degree of upper respiratory tract infection symptoms, fever, and mild itching. Family genetic factors may also cause some people to develop cherry-like hemomalies earlier. If the red dots persist or increase in number, it is recommended to seek medical examination to determine the cause.

gearA gear was a type of mechanical component. It had a tooth shape and could continuously mesh to transmit motion and power. Gears could be divided into different types according to the tooth shape, the shape of the gear, the shape of the tooth line, the surface of the gear teeth, and the manufacturing method. Common types of gears include cylindrical gears, conical gears, oblique gears, racks, and worms and wormwheels. Gears had a wide range of applications and could be used in a variety of mechanical equipment, such as mechanical watches, electric fans, and blenders. The design specifications and material selection of gears were determined according to the specific application requirements. The parameters of the gear included module, pressure angle, tooth height, tooth thickness, gear diameter, center distance, tooth backlash, etc. The development of gears was very mature. Modern gear technology could achieve very small modules and large diameter, and the transmission power and speed had a wide range. In short, gears were an important mechanical component. They had the advantages of efficient transmission, strong carrying capacity, and stable operation.
