1. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
mining machine is a tool for procing and mining bitcoin

4. Your idea is very good. In order to make contributions to China's top 22 enterprises, you must study the major of mechanical design and manufacturing and electrical automation in the direction of mining machinery. Only by studying hard can you get the recognition of the recruitment team and appointment officer of Shenhua head office! Learning is the first major direction. Effort is the second principle

5. The bearings of the key parts of Sany mining machinery SRT series mining mp truck are imported Timken bearings!

7. Hello
Sany company's treatment and development are still good, and one of the few private companies with such vitality
if it can help you, I hope to adopt it.

8. Which piece of debugging do you mean?
the debugging of Sany mining machine to the tramcar is mainly about the performance of the tramcar to see if it can meet the design requirements

9. Ha ha, this friend...
I can't say I'm your elder for a while. I'm three months older than you, so I can be your elder. Answer your question with nearly a year of R & D experience
the enterprise I work in is similar to sany1 in construction machinery, and its procts are also very similar. Of course, the nature of enterprises is different. When I work in state-owned enterprises, Sany's activity as a private enterprise is certainly better than that of state-owned enterprises
you're right. Sany head office does research and development, and the ecation threshold is a little higher. I also have classmates in Sany, and they can only do proction technology jobs at most. Moreover, for most of us, it's very difficult for undergraates to directly do research and development in Sany. This is a fact (he is not short of people)...
but you can try Sany's subsidiary, For example, the excavator division, Sany mining machinery, Sany Heavy equipment and other subsidiaries have a little lower income than the head office, but they are all fast-growing subsidiaries, and the demand for R & D personnel is very large, so there is still a good chance
however, Sany, as a private enterprise, is more impetuous (now the state-owned enterprises graally begin to have this problem), that is, it is more inclined to dig people and mature people, rather than patiently cultivate new people to do research and development< There is no difference between undergraates and postgraates. At least I don't feel that undergraates can learn all the things that postgraates can learn in a short time. Moreover, those things have no use for practical work. Even if it is applied analysis, undergraates can learn it by studying hard, but they don't give any chance
it's a fact that Sany head office recruits postgraates, but it doesn't mean that all its subsidiaries can recruit postgraates. Our company doesn't mean that only postgraates are recruited for R & D work when it comes to recruitment, but the fact is that I have not come in the same way. Of course, there must be certain opportunities
1. Big business or small business
large enterprises are more formal, learn standard things, and train new people systematically in a hierarchical way, which is beneficial for the long run. However, the threshold of large companies is generally higher, and whether they can get the job they like depends on their own efforts and some luck. Always in the workshop? No, there must be job rotation training. Of course, there is no job rotation training needed urgently. It depends on the needs of the company. Several of me and I have just been working for a month, and the workshop was taken away. I think Sany's subsidiary should also have many opportunities like mine, because it is an enterprise with rapid development and expansion
the answer on the second floor is very good. I personally agree that graate students are only useful for a while. When they come in, they will still rely on themselves later. If they do quality and technology, they will have a great chance to do research and development in the future, and they can lay a solid foundation. I do it like this. Fortunately, the foundation is still a little bit, or I will sweat to death
small enterprises, including small project teams of large companies, have many things that are not standardized and may come into contact with everything. One obvious advantage is that there are many opportunities for exercise. Just let it go. But the disadvantages are more obvious. After a long time, I find that I only know the technology, and the technology is not very good. If I develop bad habits, it is difficult to integrate into the formal team in the future. As for how to choose, there are different opinions
2. Mechatronics is the general direction of machinery, and electricity is just a tool, which I don't agree with. We can see how much our company takes in a month from Sany excavator division. In general structural design, it is difficult for pure machinery to compete with electricity. The prospect of electro-hydraulic direction is very good, but it's very difficult. It can't be achieved overnight. I don't need to say the hard work. It's also the sorrow of domestic technology instry. General mechanical, as long as you know the general design and common sense of electrical fluid, it is already very good
I don't have much experience, and I don't need much advanced R & D level for construction machinery. Most of my mechanical knowledge is used in traditional ways. A few years ago, it was quite training
ha ha, it's OK not to do research and development immediately, but to accumulate slowly. It's impossible to do mechanical work. Of course, I feel that it's better not to do mechanical work, ha ha...
for others, let's wait for our predecessors to supplement
to add to your question, it's true that state-owned enterprises are all apprentices led by masters (I'm in state-owned enterprises, and I'm very responsible to say that's right. Sometimes masters have to sign an agreement to guarantee how long they will bring their apprentices out), and they can quickly start with Masters (only limited to conventional technology). The salary of SINOTRUK is not very good, so we should consider it carefully. However, the R & D of automobile instry has a large contact area, which is very helpful for the accumulation of technology in previous years. I don't have any classmates in Gao tooth, so I can't make a final conclusion. However, the salary of state-owned enterprises that make parts is generally not high, but one advantage is that they definitely learn more about the more conventional theories of machinery, such as machining accuracy, heat treatment, tolerance and so on. If they can do research and development, they will train people
small companies are not standard, so consider carefully. I haven't tried it in foreign enterprises. I hope you can have a try and share your experience with us. ha-ha.
