Blockchain EEC
the earliest appearance of the former was in 2015. In the two years from 2015 to 2017, the personnel of Vicat MLM organizations, through false propaganda, selling Vicat, holding various propaganda meetings and establishing class system, led to more than 200 countries and more than 3 million people being cheated. Although in 2017, Vicat coins have been cracked, a total of 119 backbone were arrested. However, e to the large number of people involved in Vicat, even if the backbone is captured, some offline people are still using Vicat to continue to commit fraud. In the first half of 2018, many people found signs of recovery of Vicat
top 2: mchain (M-chain or MCC)
mchain, formerly known as M-chain or MCC, appeared in the second half of 2017. Through the Ethereum blockchain, the personnel of MCC pyramid marketing organization generated token MCC for free. Through careful packaging (for example, putting token MCC online to some unknown Shanzhai exchanges, inventing Galaxy online entertainment platform and cloud mining machine), they attracted investors to invest and promised high returns to investors. After investors take the t, MCC MLM organizations will ince investors to develop offline through other means< At present, MCC has not been detected by the police and is still active. However, Yuhang Public Security Bureau and Zhejiang Economic Investigation Bureau have already issued a warning, hoping that you will not easily get on the stolen ship that has lost your property
Top 3 of MLM: radar coin (ADAR)
radar coin appeared in 2014 and was exposed as a pyramid scheme by CCTV and public security in many places. It was once known as the largest online MLM project in China, but up to now, radar coin is still active
radar coin mainly relies on the Internet and community for promotion. As few people knew the concept of mining in the early years, radar coin was introced to store or promote the concept of mining, and it has continued to this day. As early as 2016, radar coin was stripped out, formerly known as VPAL (also pyramid scheme), because the source code of radar coin and VPAL is consistent, and radar coin uses the domain name of VPAL<
Top 4 of MLM coin: LCC (light cone)
LCC is a MLM coin scam that appeared around November 2017. MLM organization staff incited investors to take the initiative to invest and develop offline by manipulating prices and drawing big cakes. In just a few months, it expanded the scope of fraud to more than 10 provinces and cities in China, resulting in 50000-80000 people being cheated, The amount involved reached 4.9 billion yuan. At present, the top management of LCC pyramid marketing organization has been arrested by the police
Top 5 of MLM coin: Xinghan chain (SGC)
Xinghan chain was launched in September 2017. Like all MLM coins, Xinghan chain often holds various conferences at home and abroad to attract members and publicize Xinghan chain. Although the people of Xinghan chain pyramid scheme deliberately designed a complex algorithm in an attempt to cover up the fact of incing investors to go offline, it is just like mmm, the world's largest Ponzi scheme, and static income sold them out
in December last year, Xinghan chain was singled out as MLM. Five days later, it was suspected of MLM by Changsha crackdown office. In April this year, it was reported as MLM by many media platforms< Top 6: electric energy chain (EEC)
there is no official website, no white paper, nor shangshanzhai exchange. The only white paper with a little technical content is completely copied. The transaction is purely by manual transfer. If you transfer 1000 yuan, you will be charged 500, and if you transfer 2000 yuan, you will be charged 1000. At first glance, I thought it was charging QQ card. Buy 1000 coins a year, only 12 coins of income, to profit completely depends on the development of offline. It was exposed in May this year that it is a pyramid scheme< Top 7: popular money (TPC)
popular money appeared around may 2017 and was exposed as MLM by Hong Kong East weekly on February 4 this year. TPC has white papers, official websites, wallets, exchanges, points websites, game applications, and formal business licenses. It has a clear division of labor and strict discipline. No one would have thought that it would be a pyramid selling coin if it did not need to pay a threshold fee of 40000 yuan for one person and get a rebate for joining the army< In late March of this year, Datang launched illegal pyramid selling in the name of blockchain all over the country, and in just 18 days, it expanded its registered members to more than 13000, involving 31 provinces, cities and autonomous regions. Xi'an police set up a special team to destroy the case after receiving the report. According to the statistics after the incident, the amount of money involved in the case exceeded 80 million yuan, and this case has become the first "blockchain" mega network pyramid selling case in China
Top 9: Hero chain (HEC)
hero chain was listed on January 13 this year. Investors hesitated and repeatedly decided to report the case when people on the platform were cheated, the currency price plummeted and the market value evaporated by 90%. On March 14, 2018, the hero chain was put on file for investigation, and the relevant person in charge disappeared immediately after putting on file
Top 10: PMD (pyramid)
PMD was launched in June 2018, which completely imitated MCC's pyramid selling routine. After careful packaging, virtual cloud miner carried out fraud and hierarchical pyramid selling. Because PMD imitates MCC too much, it was discovered by the people of MCC MLM organization and exposed
top 11: WSC
WSC appeared around February this year. There is no white paper. The so-called official website is also composed of some scattered words and pictures. The staff of the pyramid marketing organization of Wenshang chain invented the cloud miner and launched the "welfare" of sending miner after registration to attract members. After the investors took the t, the staff of the pyramid marketing organization of Wenshang chain would pull the investors to the "business school" for centralized brainwashing training and development offline
Top 12: DK appeared at the end of 2015, which completely imitated the operation mode of MMM and learned from the experience of MMM crash, changed the realization time, promised 1% income and cheated investors. If investors think that the return of static income is slow, the people of the tic money pyramid marketing organization will encourage investors to develop offline, and set up a 20 layer pyramid hierarchical system, so that the leeks that have been locked up can trick new leeks into the pit. As the operation mode of tic is constantly changing, and its behavior is relatively low-key, so TIC has not been able to attract the attention of relevant departments and is still active

Electromagnetic compatibility (EMC) refers to the ability of equipment or system to meet the requirements in its electromagnetic environment and not proce unbearable electromagnetic interference to any equipment in its environment
With the development of modern science and technology, the number and types of electrical and electronic equipment are increasing, which makes the electromagnetic environment increasingly complex. In this complex electromagnetic environment, how to rece the mutual electromagnetic disturbance and make all kinds of equipment work normally is an urgent problem to be solved; On the other hand, the bad electromagnetic environment will have a bad impact on human and ecology 
extended data:
EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to the environment in the normal operation process cannot exceed a certain limit value; On the other hand, it means that the instrument has a certain degree of immunity to the electromagnetic interference existing in the environment, that is, electromagnetic sensitivity
in recent years, with the wide application of high sensitive electronic technology in medical electrical equipment and the rapid development of new communication technologies, such as personal communication system and cellular telephone, in various fields of social life; Medical electrical equipment not only emits electromagnetic energy, which affects the radio communication business and the work of other surrounding equipment, but also may be interfered by electromagnetic energy emission from surrounding equipment such as communication equipment in its application environment, causing harm to patients
filter connector is often of great help to the EMC performance of procts, but its cost is relatively high. Generally, when the problem can be solved by using on-board filtering, cable shielding and other methods, filter connector is not used. Filter connectors are usually used in some special situations, such as strict military standard requirements, small batch applications in harsh instrial environment and some special situations (such as structure size restrictions)
the research of EMC theory and technology in China started relatively late, and its development in the medical field only started in the 1990s. In 1995, China issued GB 9706.1-1995 General requirements for safety of medical electrical equipment. It was not until April 5, 2005 that the former State Food and Drug Administration issued the mandatory instry standard for medical devices YY0505-2005 Medical electrical equipment Part 1-2: General requirements for Safety - parallel standards: electromagnetic compatibility - Requirements and tests

suggestion:
you only have 4MB ADSL, and you don't have the conditions to build your own website server. You'd better go to the space service provider and buy the space and domain name together. They will do a good job in changing the domain name for you, and save the cost of purchasing fixed IP.
