Shiye is the enterprise Ethereum Alliance
Eth is the Federal Institute of technology of Zurich, located in Zurich, Switzerland. It is a world-renowned top research university. For many years, it has ranked first in European universities and enjoys the reputation of "the first university in Europe". It ranks sixth in the world in the comprehensive ranking of QS World Universities in 2020
The Federal Institute of technology in Zurich was founded by the Swiss Federation in 1854 and began to teach as a technical college in 1855. Initially, it consisted of six faculties of architecture, civil engineering, mechanical engineering, chemistry and forestry, as well as an organization integrating mathematics, natural sciences, literature, social sciences and politicsthe Federal Institute of technology of Zurich ranked 9th in the world in the 2016 QS World University comprehensive ranking; In 2017, QS ranked the eighth in the world; Ranked 10th in the world in the comprehensive ranking of QS World Universities in 2018; Ranked 7th in the world in the comprehensive ranking of QS World Universities in 2019; In 2020, QS ranked the sixth in the world
the development status of eth
the Swiss Federal Institute of technology was established by the Swiss Federal Government in 1855 for the needs of national instrialization, which is a Federal University. It is not only for its own development, but also for the whole country, Europe and even the world to engage in scientific research. At the beginning, the university only had civil engineering, forest science, mechanical engineering and chemistry, and then added humanities, sociology and political science
the school has 26000 teachers and students from more than 100 countries in 16 departments, and its teaching and research fields include architecture, engineering, mathematics, natural science, social science and management science. For eth, the number of students enrolled and tuition fees are not considered at all. With the support of the federal government, the college receives as much as 9.2 billion Swiss francs a year for ecation, which does not include the use of property management and new teaching facilities
the college has also received up to 3 billion Swiss francs from third-party funding and its own technology transformation. All these funds are used for school running and scientific research, or most of them are directly used for more than 20000 students and 500 professors (full-time equivalent personnel of more than 9000 person years)
Even so, ETH continues to say that it is short of money in its annual reports in recent two years, and the reason is very simple. In order to compete with other institutions (universities), our independence is the most important, so we need a long-term sustainable financial supportlast year, we expanded the enrollment of 4% of the students. At present, the number of students is 156% of that ten years ago, the number of professors has increased by 23%, and the number of scientific research personnel has increased by 53%. However, the government's scientific research funding has only increased by 42%, and the available area for ecation has only increased by 7%. We are facing great challenges
However, it is not surprising in Switzerland. Due to its unique ecation system, all resources in Switzerland are concentrated in 10 universities and 2 federal polytechnics. In other words, there are only 12 universities at the level of higher ecation, and the country is not short of money, so the current situation is formedthe first stage: the basic theory of blockchain technology is suitable for students who have various needs for blockchain technology. It is the most comprehensive and up-to-date curriculum system at present. With the rapid appreciation of bitcoin, blockchain technology has become more and more sought after and studied by people from all walks of life, Or from the perspective of technology research and development, this set of courses are very suitable for you to download and learn. Schele: Lesson 1 ICO & amp; EOS understands the risks of ICO and ICO projects, How to judge whether an ICO is reliable lesson 2 the past and present of bitcoin blockchain understand the origin and related background knowledge of bitcoin and blockchain lesson 3 cryptography master the necessary knowledge of blockchain related cryptography lesson 4 bitcoin transaction in-depth discussion of what happened behind bitcoin transaction lesson 5 block generation and link in-depth discussion of how blockchain is generated Lesson 6 bifurcation principle of blockchain and how to operate the coins in hand before and after the bifurcation Lesson 7 how does the wallet know how much money I have and how to hold the coins in hand more safely Lesson 8 mining understanding the history and principle of mining, Experience mining in bitcoin regression test environment Lesson 9 blockchain security, understand the security problems of blockchain, how to "steal" other people's money Lesson 10 smart contract learn the principle of blockchain 2.0 smart contract, understand how the smart contract is written and run

stage 2: introction to blockchain technology research and development, Blockchain technology is a very popular new technology at present, which is highly praised by large IT companies and experts all over the world. Not long ago, the blockchain technology platform enterprise Ethereum Alliance (EEA) announced its formal establishment, and nearly 30 giants including JPMorgan Chase, Microsoft and Intel joined in. Extremely optimistic about the future of Ethereum. At present, the term blockchain is very popular, but few people really understand blockchain technology. If you no longer want to be a onlooker, you are welcome to learn this course. After learning this course, you can master the following contents: deeply master the blockchain technology, understand what mining is, learn how to build your own blockchain network, how to publish your own applications on your own blockchain network or enterprise Ethernet network, and how to write smart contracts, Blockchain technology applications. This course is based on practical teaching, mainly teaching front-line practical skills, to ensure that students can quickly learn to apply! Timetable: 1.

(1) jaw crusher (tiger mouth): the crushing action is to periodically press the movable jaw plate to the fixed jaw plate to crush the ore block in it
(2)
cone crusher: the ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block
(3)
roller crusher: in the gap between two opposite rotating round rollers, the ore block is mainly subject to continuous crushing, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting
(4)
impact crusher: the ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher<
(5)
grinding machine: the ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder
(6)
other types of crushing mills: A. roller mill: crushing materials by rotating rollers< B. disc mill: the disc rotation of vertical axis or horizontal axis is used as crushing part
C. centrifugal mill. High speed rotating parts and medium are used to proce centrifugal force to complete crushing
D. vibration mill. High frequency vibration is proced by the rotating shaft, which makes the medium and material collide with each other to complete the crushing effect. All kinds of crushers have different specifications, different scope of use. At present, jaw crusher or rotary cone crusher are mostly used for coarse crushing in concentrator; The standard cone crusher is used for intermediate crushing; Short head cone crusher is used for fine crushing.
