3. Are there any poems and articles about scientific and technological innovation? Why do most household appliances such as electric fans, washing machines and refrigerators use three-wire plugs? What is the difference between a three-wire plug and a three-phase plug? Three-phase electrical appliances refer to three different live wires, and the voltage between each two wires is 380 volts. They are generally used in power systems and are more common in industrial electricity consumption.
Single-phase power supply is generally used in household appliances, and its three wires are live wire, neutral wire and ground wire. The voltage between the live wire and the neutral wire is 220 volts, so this is not three-phase electricity, and its plug socket is not a three-phase plug socket. The grounding wire is to ensure safety. Fruit hawthorn with antihypertensive effect; Hawthorn can dilate blood vessels and lower blood pressure and cholesterol.
You can choose 10 wild hawthorn (fresh is better), mash it with 30 grams of white sugar, and take it after decocting in water, which has a good effect of lowering blood pressure and invigorating stomach. Bananas; Bananas contain a variety of vitamins, which can clear away heat and lower blood pressure and can be eaten regularly.
It is also effective to decoct with 30~60 grams of banana peel or fruit stalk. Take a proper amount of plantain flowers and take them with water, and the curative effect is better.
Water chestnut; It has the effect of clearing away heat and lowering blood pressure. You can use fresh water chestnut (washed, mud removed) and jellyfish (washed and salt removed) to cook soup three times a day.
It can not only lower blood pressure, but also reduce phlegm and relieve cough. Pineapple basket: Eating pineapple regularly can strengthen the hydrolysis of fibrin in the body, which has a good effect on improving blood circulation and eliminating edema and inflammation in hypertension, edema and thrombosis.
Mume: Rich in citric acid, malic acid and succinic acid. For those with hypertension, dizziness, insomnia, and difficulty sleeping at night, 3 pieces of dark plum and appropriate amount of rock sugar can be stewed in boiling water, which has the functions of lowering blood pressure, sleeping peacefully, clearing away heat and promoting fluid production.
Apple: contains malic acid, citric acid, vitamins A, B, C, etc. 10. Eating apples often can improve arteriosclerosis. Scientific tips for drinking milk are beneficial to health, but many people still have some conceptual misunderstandings when drinking milk. Here are some tips for drinking milk scientifically.
1. It is not advisable to drink milk on an empty stomach in the morning. Because the gastrointestinal peristalsis is fast when the human body is on an empty stomach, the nutrients in milk often rush into the large intestine before being absorbed.
In addition, the method of swallowing milk is not feasible, because it will reduce the chance of mixing with saliva in the mouth, which is not conducive to digestion and absorption. You'd better eat some biscuits, cakes, etc. Before drinking milk, or eating snacks while drinking milk.
Drinking milk at night is more beneficial. Scientific research has found that there is a special law of calcium metabolism in human body: at night, especially at midnight, the plasma calcium content will appear a "trough", forcing the body to transport part of calcium in bones to supplement it through regulation mechanism.
Although this temporarily maintains the calcium in the blood, the calcium in the bones is reduced. Milk is rich in calcium. Drinking a glass of milk before going to bed can compensate the body's demand for calcium at night.
Milk should not be cooked with sugar. Milk is rich in amino acids. At high temperature, lysine in milk reacts with sugar to produce a new compound-fructosyl amino acid.
This substance can't be digested and absorbed by human body, but it affects human health. It is best to drink fresh milk. If it is too cold, you can heat it a little. If you don't like milk, you can drink yogurt.
Most people who hate milk suffer from lactose intolerance. These people can try to drink yogurt. The lactose content in yogurt is greatly reduced, but almost all the nutrients in milk are retained. Among them, lactic acid bacteria can survive and reproduce in human body, which is beneficial to the absorption and utilization of nutrients and improves immunity.
Yogurt contains no antibiotics, is easy to digest and absorb, and can be drunk on an empty stomach. 5. Yogurt can't be heated for drinking.
Drinking yogurt is mainly about eating its nutrients and living bacteria. For example, when yogurt is heated, the human body can only drink nutrients but lose bioactive lactic acid bacteria, so don't drink it after heating. Mercury is the smallest earth-like planet in the solar system.
It is difficult to observe because it is blocked by the strong light of the sun. On his deathbed, Copernicus regretted that he had never seen Mercury in his life.
Since the 1970s, people have learned more about water quantity. Mercury is the smallest earth-like planet in the solar system.
It is difficult to observe because it is blocked by the strong light of the sun. On his deathbed, Copernicus regretted that he had never seen Mercury in his life.
Since the 1970s, people have learned more about water quantity. Mercury is the closest to the sun, only 57.9 million kilometers, which is 0.387 times the distance between the sun and the earth. Mercury's equatorial radius is about 2/5 of that of the earth.
Mercury has no air. Mercury looks very similar to the moon, and its surface is covered with craters of all sizes.
Volcanic activity may have occurred hundreds of millions of years ago. Now there are several plains that look like volcanic lava on the surface of the star, and there are craters everywhere, large and small. Mercury has a huge concentric structure with a radius of about 1300 km. It is located at 30 degrees north latitude and 0/95 degrees west longitude of Mercury. Because it is extremely hot, it was named "Calorie Basin" by scientists.
There are more than 100 craters with radial stripes on the surface of Mercury, and a large number of cliffs three or four kilometers high, some of which are hundreds of kilometers long. The density of mercury is close to that of the earth.
Its center may be a core of iron and nickel similar to the size of the moon, and it also has a magnetic field, but its intensity is only1100 of that of the earth. Mercury's orbital speed is 48km/s, which is faster than the Earth's 18km.
It only takes 88 Earth Days, and less than three months after the Earth, Mercury will be 1 year. However, Mercury's "day" is very long. Mercury rotates 1 nearly 58.65 earth days, which means that 1 day of mercury is nearly two months of the earth, and only two sunrises and sunsets can be seen in 1 year on mercury.
Mercury, like Venus, has no satellites. Scientific and technological figure /chinababyxl/kwbc/kjrw/ Hua is one of the leading mathematicians in number theory.
But he would rather start a new stove and leave number theory to study algebra and complex analysis that he is not familiar with. As early as 1940s, he proposed that "genius lies in accumulation, and cleverness lies in diligence".
Although Hua is brilliant, he never mentions his talent. Instead, he regards "diligence" and "accumulation", which are much more important than cleverness, as the key to success, and repeatedly educates young people to learn mathematics so that they can exercise themselves at any time. In the mid-1950s, Hua proposed: "There should be speed and acceleration." The so-called "speed" means producing results, and the so-called "acceleration" means constantly improving the quality of results.
1978, he earnestly put forward at the Chengdu conference in chinese mathematical society: "Early publication, late evaluation." Later, it was further proposed: "Work hard.
