1. The story of Edison
Edison only went to primary school for three months in his life. 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
"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 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. 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!"< 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."

2. Duan Jiaxuan, a research fellow in the machinery instry of CIC, pointed out that the construction machinery market in the second quarter was in decline, and the market was looking forward to the acceleration of affordable housing construction in the second half of the year. From the current construction progress and current situation of affordable housing in the market, there were mixed feelings. Benefited from the sustained and rapid growth of China's real estate and infrastructure investment, the growth of concrete machinery exceeded expectations, which once again highlights the inertia of China's relying on heavy instry to drive economic growth still exists

as an important part of construction machinery, the huge demand space of the market and the rapid development of the instry promote enterprises to continuously accelerate investment. With the acceleration of market investment, the competition between enterprises is also increasing. At present, the investment in the market tends to be irrational, and the market is still worried. On the basis of the decline of infrastructure investment, despite the bullish worries, the investment growth of leading enterprises has not decreased at all

according to the "2011-2015 China machinery instry investment analysis and prospect forecast report" released by CIC consultants, in the fierce market competition, market expansion is undoubtedly the common competition mode adopted by all enterprises. The market is in an accelerated state, and the competition is also accelerating, and there is a growing trend. The entry of Shantui and Liugong, together with the expansion of XCMG's concrete machinery instry, will form a direct competition with Zoomlion and Sany Heavy Instry, which have been dominating the concrete machinery instry for many years< According to Zhang Yanlin, research director of CIC, mining machinery is still a promising sub instry. The growth of mining equipment instry mainly depends on the investment in infrastructure construction. Due to the rapid development of China's economic construction, there are still many projects, including roads, railways and real estate. In the future, the development of mining equipment instry will continue to increase, The infrastructure investment kept at a certain level will become the main growth power of mining equipment instry in 2011.

3. I'm a PhD student in mechanics of Dalian University of technology. I'd like to give you some advice
this year's retest score line is about 300. For those with relatively high enrollment ratio (and Dagong doesn't give adjustment to other majors), the re examination score is 200 points, including English listening, speaking and professional courses. Professional courses include: theoretical mechanics, structural mechanics, elastic mechanics, plastic mechanics, partial differential equations, dynamics, tensor analysis, but they all test some simple basic questions, and some are questions ring the interview. These are the main professional courses required by mechanics of large engineering. It is suggested to study them carefully
about 30-40% of them are exempt from the test
the computational mechanics and engineering mechanics of Dagong are first-class in China, so we should work hard to see you report in Dagong next year.

4. In general, mechanics in Tsinghua University is better. Mechanics is an engineering subject, and Tsinghua University ranks first in China. However, if you are not talking about mechanics in the usual sense, but quantum mechanics, then Peking University is stronger, because quantum mechanics belongs to physics and is usually classified as science. Peking University's science is very strong ~
good luck`

5. China's famous heavy machinery manufacturing Co., Ltd. Beijing first machine tool plant, Henan Yurui, etc< < br > < br > machinery manufacturing refers to the instrial sector engaged in the proction of various power machinery, lifting and transportation machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters and other mechanical equipment. Machinery manufacturing instry provides technical equipment for the whole national economy< After 35 years of reform and development, Henan Yurui company has won numerous honors, including various certificates awarded by government organizations, awards from media and market research institutions, and public praise for enterprises through formal and informal channels.

6. First, we should be able to bear hardships, because the mines are in relatively remote places; Second, we should choose a machinery company with better equipment performance, or we should have too much trouble; Third, in terms of treatment, it depends on subsidies and reimbursement, as well as whether it is a resident or an expatriate. I have a friend who worked as the after-sales service provider of Zoomlion Zhongke road roller. He arrived at home about 3000 times a month
