Artificial intelligence, blockchain, digital twins... At this year's World Internet Conference, these increasingly hot technical concepts have been repeatedly talked about by the scientific community. The prediction of the global technology development trend next year has always been one of the most concerned topics in the industry. A few days ago, the US information technology research and consulting company Garten released the annual "Top Ten Strategic Trends". Gong Peiyuan, a partner of Gartner's senior management, recently interviewed the China Net Technology reporter and gave a detailed discussion on the report, and answered questions on the development prospects of Chinese enterprises' technology. Artificial intelligence foundations, intelligent applications and analysis, and smart objects were selected as the three technologies with the most potential for development in the field of intelligence in 2018. Gong Peiyuan said that in 2018 AI will no longer be an illusory technology, artificial intelligence and machine learning will penetrate into almost any field. By 2020, 30% of corporate CIOs will include AI in the top five investment priorities, and 30% of newly developed projects will have AI technology in them. In terms of artificial intelligence, Gartner predicts that by 2025, the ability to use artificial intelligence to help decision-making, reshape business models and ecosystems, and rebuild customer experience will be key drivers of digital program success. Technically, various manufacturers have already implemented AI on the chip. The English term for this technology is AI on Chip (ie, AI is integrated into the chip). Gong Peiyuan said that in the past, AI was in the data center. There were a large number of machines "running" data, and now "enter" the chip. Deep learning is no longer just a matter of the background data center, but also a chip thing. This makes the application of AI a leap forward, and the progress rate of autonomous driving technology is the result that people can see now. Gong Peiyuan stressed that people should realistically understand that AI is not omnipotent. Compared with the engineering and logic of the code, artificial intelligence learning is based on the data export results, people can train to make the results closer to the desired results. From a business perspective, what you need to do is learn to control AI, not develop AI. Driven by artificial intelligence, the range of applications of smart objects is becoming wider and wider. Gong Peiyuan said that the breakthrough speed of AI on the smart side will be faster and faster. At the same time, due to the wide application of the smart terminal, communication between “end†and “end†will result in smarter products becoming smarter. Among them, Gartner believes that autonomous vehicles for use in a controlled environment will be an area of ​​rapid growth of smart objects. By 2022, people will witness first-hand examples of autonomous vehicles driving on limited, controllable and well-defined roads. Digital technology trends, digital hygiene, cloud-to-edge, conversational platforms, and immersive experiences are on the list. Gong Peiyuan said that by 2020, 95% of the machines will cover the "end" of the Internet of Things, and the Internet of Things will help consumers and businesses save $1 trillion in operations, maintenance and services. At the same time, Gong Peiyuan pointed out that 2018 is the integration of cloud and edge computing, and edge computing will rise in 2018. Digital hygiene is the digital reproduction of real entities or systems. Digital hygiene can bring three benefits: observing business operations from a virtual environment; seeing operational results from a virtual environment; and predicting the results of optimization points in a virtual environment. Gartner predicts that digital twins in the context of the IoT project will be particularly promising in the next three to five years. In terms of human interaction with the digital world, Gartner believes that a conversational platform will drive the next major paradigm shift. Gong Peiyuan pointed out that the essence of the conversation platform is not a dialogue, but a perceptual interaction, a dialogue of words and things. Gartner believes that in the next few years, the session interface will become a primary design goal for user interaction, and will be implemented through dedicated hardware, core operating system features, platforms, and applications. With the development of technologies such as VR and AR, immersive experience technology has attracted more and more attention. If conversational interfaces change the way people control the digital world, then virtual, enhanced, and mixed reality are changing the way people interact with the digital world. However, Gartner pointed out that the virtual reality and augmented reality market is still immature and still in the fragmentation stage. However, people's interest in the field is very strong, which has spawned many novel virtual reality applications such as video games and 360-degree dome video. However, the commercial value of these advanced entertainment applications is currently very small. Blockchain landing will be seen in 2018 Mobile and safely breaking the company's barriers or bottlenecks is the focus of grid technology trends, blockchain, event-driven and continuous adaptive risk and trust are listed on the list of technologies. The blockchain is undoubtedly one of the hottest technology of the moment. In addition to the well-known financial services industry, blockchain has potential applications in government, healthcare, manufacturing, media distribution, identification, ownership registration services, and supply chains. Gartner believes that although the blockchain has a promising future and will undoubtedly have a subversive impact, the outlook for blockchain outweighs the reality of blockchain, and many related technologies are difficult to mature in the next two to three years. Gong Peiyuan believes that 2018 will be a year for the blockchain. "People will know how high its actual landing is and how much speculation it has," he said. To ensure that digital business initiatives are still effectively implemented in the face of advanced targeted attacks, Gartner believes that companies should adopt continuous adaptive risk and trust technologies to achieve real-time decision-making based on risk and trust with adaptive response. At the same time, it can be combined with trapping techniques. "Build a bait and let the hacker fight the bait. Because you can't guard against everything. The only thing you can do is to 'cheat' him to the other side. This is a continuous, progressive defense for the company. Gong Peiyuan said. Why do you like to use ferrite magnets? Because it does not rust, does not oxidize, does not corrode and is absolutely environmentally friendly.

Why don't ferrite magnets rust?
The chemical name of ferrite magnet is iron tetroxide. The main components are: Fe3O4. It is already an oxide of iron, so it is very difficult to be oxidized again. Other magnets (the main component is iron) are made of magnetized metal iron or other elements. Like other iron and steel, they can be oxidized and rusted, and the oxidized part will lose their magnetism.
What are the advantages (advantages) of ferrite magnets
1. Low cost, low price. Raw material cost is cheap.
2. Good temperature stability. It can be used in temperatures of -40 degrees Celsius and +350 degrees Celsius.
3. It is just mentioned that it does not rust.
4. The demagnetization curve is approximately a straight line.
5. Light weight, density is (4.6-5.1) X103kg/M3
6. The anisotropy constant of the magnetic crystal is large.
7. Large coercivity Hc (between AlNiCo alloy material and rare earth cobalt permanent magnet material)
8. High resistivity.
