magma is the same way

4. It's not easy to find a reliable miner. The current miner is basically a process of transportation. It's not easy to be a miner

5. In the 1990s, China's mining machinery instry was the most difficult period. After entering the 21st century, China's mining machinery instry began to rise, and enterprises got out of the loss predicament and ushered in the development opportunity. However, the scientific and technological foundation of China's mining machinery instry is still relatively weak, and market for technology has always been the main way of development

the first problems existing in China's mining machinery instry are as follows: first, the comprehensive strength of mining machinery enterprises is not strong, and most enterprises are stagnant in terms of energy and capital investment in scientific research, new proct development, technological transformation and enterprise management. The domestic mining machinery procts, especially the key equipment urgently needed by the national construction, can not meet the requirements, and there are some problems, such as low technical content, low added value, unstable proct quality, low labor proctivity, etc., which cause the output value growth rate and profit growth rate of mining machinery manufacturing enterprises in our country is not commensurate

secondly, there are problems in proct variety, technology, quality and service, which lead to the low actual contribution rate of domestic mining machinery instry to mines. Taking metallurgical mines as an example, there are 1180 kinds of equipment in use at present. Only about 26% of the equipment can be self-sufficient in China, and most of them are low technology and low quality equipment. The rest
74% still need to be imported. Domestic equipment, especially mobile equipment with high technology content, such as full face roadheader, mining truck, excavator, scraper and so on, has a big gap compared with imported equipment

in terms of equipment manufacturing, China's mining machinery enterprises are relatively backward in both technology and experience, and have no perfect equipment. If we want to improve the comprehensive strength of China's mining machinery instry, we must first make efforts in scientific research and technological transformation and independent innovation. Since its establishment, Xinhai Mining Machinery Co., Ltd. has been adhering to the road of independent innovation, and the comprehensive energy saving of the world's first full section airlift micro bubble flotation machine can reach more than 85%; The superfine laminated autogenous mill has no st pollution and can double the capacity of the ball mill<

according to the analysis report on the development prospect prediction and investment strategic planning of China's mining machinery instry published by the Research Institute of prospective instry, the innovation of mining machinery instry can be achieved through the following ways:

firstly, the mining machinery manufacturing instry should establish different forms of alliances with foreign companies and domestic professional design institutes, including the formation of groups, consortia, the introction of technology, the introction of new technologies, the establishment of new technologies and the establishment of new technologies To introce talents, we should at least strive to adopt the method of joint design in a certain engineering project, first intervene and then improve, so as to achieve a win-win situation

secondly, it is necessary to establish and improve the Application Laboratory of advantage specialty as soon as possible to carry out the application technology research of proct and manufacturing process. The laboratory should start high and be practical; It includes test theory and method, test equipment and scale, control and detection technology. If necessary, foreign advanced technology should be introced. In addition, the related colleges and universities at home and abroad are not only the training base of mining machinery technical personnel, but also the origin of basic theory and experimental technology research of mining machinery, so we must take different forms of cooperation with them with the help of their strength.

6. YJL short video app is a platform of short video blockchain + miner mode. Meet the platform has been launched for 3 months, from the beginning because of the amount of sales and no

7. (1) He started his first experiment in his own wooden shed
Edison liked to think about a series of problems with his unique big head since he was a child. When he saw the blacksmith burning the iron red in the raging fire and hammering it into various tools, he shook his head and asked one question after another: what is fire? Why does fire burn? Why is the fire so hot? Why does iron turn red after it is burned in the fire? Why is iron red soft? Back home, little Edison started his first experiment in his wooden shed. He took the hay and lit it. He wanted to find out what the fire was. However, little Edison's first experiment led to a fire, burning down the wooden shed at home
(2) try to do more with less time
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty pear shaped glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. Because the bulb is pear shaped, it is not a regular status quo. Therefore, it is very difficult to calculate the perimeter and inclination of the bulb. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"
(3) even sleeping is absorbing the nutrition in the book
Edison, in order to carry out experiments, often does not go out of the laboratory for several days, does not sleep. I was so tired that I took a nap on the experimental table with a book as a pillow. One day, his friend joked with him: "no wonder Edison knows so many inventions. It turns out that he even sleeps to absorb the nutrition in the book."
(4) why can't I when hens can hatch chickens?
once, when it was time to eat, Edison still didn't come back. His parents were very anxious and looked around for him. They didn't find him in the grass shed by the yard until the evening. Father saw him lying motionless in the grass with a lot of eggs, so he asked strangely, "what are you doing?" Little Edison answered calmly, "I'm hatching chickens." It turned out that when he saw that hens would hatch chickens, he felt very strange and always wanted to try it on his own. At that time, his father pulled him up and told him that people can't hatch chickens. On the way home, he was still puzzled and asked, "why can't I, when hens can hatch chickens?"
(5) what's the secret in the beehive
Edison was always in danger because he was interested in many things. Once, he went to the house where the wheat was stored and accidentally fell into the wheat store. The wheat buried his head and could not move. He nearly died. Fortunately, he was caught by Edison's foot and pulled out in time. Another time, he fell into the water and was pulled up like a drowned chicken. He himself was shocked. When he was 4 years old, he wanted to see what was in the wild beehive on the fence, so he poked it with a branch. His face was stung by a wild bee, and he could hardly open his eyes.

8. Edison's story:
Edison only went to primary school for three months in his life, and his knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style

the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference<

the story of Edison
one snowy night, Edison's mother suddenly fell ill, and his father rushed to the doctor. The doctor said, "your mother has acute appendicitis and needs an operation.". At that time, there was only oil lamp, but no electric lamp. The light of the oil lamp was very dark, and it would be wrong if you were not careful. Edison suddenly thought of a good way, he took out all the oil lamps at home, and then put a mirror behind the oil lamp to let the doctor finish the operation smoothly. The doctor said, "son, you saved your mother with your wisdom and cleverness." Edison took his mother's hand and said, "Mom, I want to make a night's sun."

1. One day in August 1862, Edison saved a boy on the railway track, and the child's father was McKenzie, the station master of the railway station. He was very grateful for this and taught Edison's telegraph technology. Under the guidance of McKenzie, Edison learned the telegraph technology and sent his first telegram

In 1863, Edison was introced by Mackenzie to work as a telegrapher of Stratford junction station on the main line railway, but he was soon dismissed

from 1864 to 1867, Edison worked as a telegraph operator in the United States, living a vagrant life without security. During this period, Edison changed ten working places, five times was removed, and the other five times was his resignation. His footprints included Stratford, Adrian, Fort Wayne, Indianapolis, cincincinnati, Nashville, Tennessee, Memphis, Tennessee Louisville, Huron

At the end of 1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first patent for invention, which is a device that automatically records votes. Edison believed that this device would speed up the work of Congress and be popular, But a congressman told him that sometimes voting slowly was also out of political need, so Edison decided never to create inventions that people didn't need

In the late autumn of 1869, Edison came to New York alone to look for a job, but when he was looking for a job in a company, he happened to encounter a telegraph machine there was broken. Edison soon repaired the telegraph machine and was appreciated by the general manager. As a result, he became the chief telegraph technician, and had a stable working environment and salary, It provided good conditions for his later invention

In October of the same year, Edison and Franklin Popper jointly founded "Popper Edison" company, specializing in scientific instruments of electrical engineering, and invented the ordinary printing press at the same time

In 1870, Edison sold the patent right of ordinary printing press to a Wall Street company and asked the manager to make his own price. He wanted to ask several thousand dollars, but the manager gave Edison forty thousand dollars. After Edison got $40000, he built a factory on ward street in Wacker, New Jersey, which specializes in manufacturing all kinds of electrical machinery

In 1873, Edison devoted himself to the study of synchronous transmitter

In December 1874, the research work of synchro transmitter was coming to an end. The western union company promised to pay Edison 5000 US dollars and bid 25000 US dollars for his patent. It also paid him 233 US dollars per day as the cost of each line using this kind of equipment. But the western union company failed to fulfill the contract. Finally, Jay Gould bought the synchro transmitter patent with 30000 US dollars, It brought Edison through

At the end of 1875, Edison was about to have his second child. He felt that the space in his home was too narrow. The narrow gray streets and noisy environment of Newark factory also affected the working mood of the researchers. Edison finally made up his mind to move

In early 1876, the Edison family moved to Monroe Park, New Jersey, where he built a laboratory

Once, when it was time to eat, Edison still didn't come back. His parents were very anxious and looked around for him. They didn't find him in the grass shed by the yard until the evening. When his father saw him lying motionless in the grass with a lot of eggs, he asked Edison what he was doing. Little Edison replied that he was hatching chickens. It turned out that when he saw that hens could hatch chickens, he thought it was very strange and always wanted to try it himself

at that time, his father pulled him up with anger and laughter and told others that he could not hatch chickens. On the way home, he was puzzled and asked, "why can't I, when hens can hatch chickens?"
