Where is the virtual currency training institution

1. At present, the more reliable are bitcoin, Wright coin, Fuyuan coin, doggy coin, reborn coin and so on

bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system. Old brand cryptocurrency, the ancestor of cryptocurrency<

Fuyuan coin, a new generation of cryptocurrency for application business circle, is a decentralized cryptocurrency, which is generated in the proct operation and circulation of member enterprises of global Jewelry Instry Association (similar to business points). Users can obtain certain Fuyuan coin when purchasing jewelry procts of member enterprises, and Fuyuan coin can be used for shopping in member cooperative businesses, You can also trade freely on the Fuyuan currency trading platform.

2. There is no formal virtual currency trading platform in China. In the past 17 years, a document has been issued to prohibit the establishment of virtual currency trading venues in China. If there are any in China, it is illegal.

3. Virtual currency can only be traded online, it needs to be on a special website

4. Virtual property is not protected by law at present<

the association is just a special institution issued by the state, which is convenient for foreign currency exchange, a special commodity economy. In addition, money is not a problem of chaos. If money circulation and the country's economic imbalance account for the proportion of total output value, it may lead to one of the two consequences, one is inflation. Second, economic crisis. The annual macro-control and evaluation of GDP determine the amount of money in the next year. In order to maintain the economic balance of the country. Now, we can think about how the virtual currency in online games came from the society. The answer is very simple, most of the money in the game through killing monsters and winning virtual technology, no game will be a special currency issue. In other words, game currency can grow indefinitely. Therefore, this game is a very common case of inflation. Similarly, other virtual items in the game only need to be added in an appropriate way (such as plug-ins), or you can ignore the daily economic law and increase infinitely. If the property is suffering from these two completely different economic laws and influences, what will be the consequences?

5. Now the most reliable virtual currency is bitcoin, but there are few circulation channels. Some of Tencent's virtual currencies are OK, but they can only be purchased in its own procts.

6. The biggest reason for the rise in the price of the graphics card is mining, and the secondary reason is the cost of the graphics card. For example, there is a shortage of graphics memory and the supply exceeds the demand

8. The equipment on 054A is all made in China. The design basis of 054 frigate may come from the f-16u frigate used for export. Compared with the previous domestic Jiangwei class frigates, the 054 frigate is more concise and avant-garde in appearance, completely getting rid of the impression that the superstructure of Jianghu class and Jiangwei class frigates is scattered and low. Compared with the Chinese Navy's new 052B / C missile destroyer, the new 054 frigate has a more concise outline. It adopts a stepped superstructure integrated with the ship's side. The bridge, tower shaped front mast and composite rear mast / chimney structure are all inclined (and the inclined angle is generally quite obvious), avoiding acute angle and complex structure, Some equipment on the surface of the warship, such as boat crane, is also covered by bulwarks, which makes the stealth design of 054 frigate close to the advanced level of the West. The displacement and hull of 054 frigate is much larger than that of Jiangwei class II frigate with a displacement of 2250 tons. It has better ocean navigation ability and can accompany the ocean fleet. However, after the first two warships of 054 frigate were built and launched, it can be inferred that 054 frigate is still a kind of transitional warship from the eight joint haihongqi 7 air defense missile launcher. Starting from the third ship, the second batch of 054 frigates have made many significant improvements in design and equipment, among which the biggest improvement is the addition of domestic vertical air defense missile launcher, which greatly strengthens the air defense capability of this type of frigates. The improved 054 frigate is the present 054A stealth frigate. 054A stealth frigate is also a new type of surface combat ship equipped by the Chinese Navy, and a few of them can build more than two, which shows that its design has become mature. With the improvement of comprehensive operational performance and low cost, 054A frigate graally plays the role of general destroyer in Chinese fleet
while China is striving to narrow the gap with the world's naval power, Japan, a former naval power and China's neighbor, has built a strong 88 fleet as early as the 1980s to meet its demand for "1000 nautical miles ocean escort". Based on five general purpose destroyers, two air defense destroyers and one helicopter destroyer, this fleet has strong comprehensive combat capability. With the development of the times, Japan's newly-built "King Kong" class and "aitao" class air defense destroyers and "Gaobo" class destroyers have been serving in the sea one after another, and Japan's sea has formed a more sophisticated 90 fleet accordingly[ Overall layout and stealth capability first of all, 054A stealth frigate: Based on the data provided by all parties, it is assumed that the data should be 3600 tons of standard displacement and 4000 tons of full load displacement (there is also a saying that 3900 tons of target displacement and 4500 tons of full load displacement). The ship is 134m long, 16m wide, 5m draught, and the aspect ratio is close to 8.6. Maximum speed 27 knots, 18 knots, enrance 3800 nautical miles, 190 crew
in terms of overall situation, since the Chinese Navy had a lot of exchanges with the European navies in the 1980s, especially the French, Italian and British navies, and was deeply influenced by their design, when Jiangwei class frigates appeared, they inadvertently revealed some traces of the design of Western ships, When the 054 frigate appeared, it obviously borrowed some of the body designs of some French "Lafayette" frigates: popular flying shear bow, freeboard high and floating out, square stern linear structure, and small aspect ratio. Its bow is high (the height is similar to that of Russian 956 "modern" class destroyer) and its transverse section is deep V-shaped, which can well prevent buffeting and waves. Its excellent hull line shape, relatively small aspect ratio and reasonable use of fin stabilizer can ensure its seakeeping to meet the needs of ocean navigation, which has been confirmed by the second and third batch of naval escort operations to the Persian Gulf
in terms of stealth design, the effect of Lafite class is also obvious, with freeboard camber of 10 °～ twenty °， Superstructure sidewall inclination 7 °～ fifteen °， Both of them are combined into an organic whole by the corner line which is almost used to pass through the whole ship. By making its cross section present a rhombic structure, the direction of the radar radiation wave can be changed, the scattering space can be reced, the echo intensity can be reced, and the radar reflection cross section can be reced. At the same time, the corner line starts from the back part of the wall of the ship's bow side, which is strongly floating, and passes through the shielding net outside the space of the lifeboat on the side side of the midship, which is flush with the helicopter platform. Its purpose is to cover the chain winch, cable pile, windlass and other equipment on the bow deck which is not concive to radar stealth, and the design idea of deliberately recing the target signal characteristics runs through the design. In addition, radar absorbing coating is used to further improve radar stealth performance. In terms of acoustic stealth treatment, diesel engines and generators use double-layer raft devices to rece vibration and noise, and the use of new low-noise 5 large side slope low-speed propeller also strengthens this purpose. In the infrared stealth processing, its huge chimney shows that it has spray cooling facilities to suppress infrared radiation
let's look at the "high wave" class: 151 meters in length, 17.4 meters in width and 5.3 meters in draft. The standard displacement is 4650 tons, and the full load displacement is 5500 tons. The ratio of length to width is 8.88, the maximum speed is 30 knots, carrying 175 people. In addition, the layout of engine room is similar. The differences are mainly reflected in the bridge, helicopter hangar and chimney. The ship has excellent ocean navigation quality to ensure that it can normally use oqr-2 low-frequency towed sonar to carry out anti submarine operation in bad sea conditions
in the stealth design, the "high wave" class also uses two methods: shape modification and absorbing coating (such as the use on the mast) to achieve the goal of weakening the radar reflection. Its hull is 8 ° The cross section is V-shaped e to the outward inclination of the cross section; The superstructure should be designed to eliminate the radar reflection as much as possible; In terms of infrared and noise stealth, relevant infrared suppression devices, shock absorbing floating rafts, low-noise and highly skewed propellers, and aerosol noise rection systems are also adopted to improve the comprehensive stealth capability. The overall stealth effect has reached the world advanced level[ Power system in power system: 054A is also influenced by Lafite class, and adopts CODAD power propulsion mode, which is composed of four pilstek 16pa6v280stc diesel engines proced by Shaanxi Diesel according to the license, with a single maximum power of 6400kw and a total power rate of 25600kw. Two new 5-blade adjustable pitch and large pitch low speed propellers are driven by two shafts. The design of the air intake in the lower front of the chimney is similar to Burke's style. The large size of the chimney indicates that it has a spray cooling facility to suppress the infrared radiation. In addition, there are two mtu-396 diesel generator sets with power of 1500kW, reaching the same level as "high wave". Don't underestimate this change. One of the reasons why the modernization of Chinese Navy destroyers and frigates was very small in the past was that the power of the power station was very small (400KW), which could only meet the power supply demand of the electromechanical, electronic and weapon equipment on board when they were newly built. The reserve power could not meet the needs of the newly improved equipment on board. As a result, the modernization was only related to communication and communication In the field of electronic warfare and other systems
many people have different opinions on the use of CODAD power mode for 054A. In fact, the power mode of CODAD first appeared on the French Navy's Casar class air defense missile destroyer. Its four high-power pierstick 18pa6v280btc diesel engines can output 31752kw of total power, so that the 5000 ton Casar can reach 29.5 knots. It was a good area air defense ship for fuhee and later Charles de Gaulle (CVN). Later, the Lafite class adopted the CODAD power unit composed of four 16pa6v280stc diesel engines. In fact, Lafite class still exists in the formation of French aircraft carriers. Considering that the output of domestic gas turbine can not meet the Navy's needs at present, the first thing is to ensure the demand of domestic large ocean destroyer. At the same time, the technical support department of the Chinese navy has rich experience and complete technical means for long-term maintenance of such power plants. Therefore, it is the most appropriate project to use advanced and mature high-power medium and high-speed diesel engine as the main power device of medium-sized warship
rihai has fully implemented COGAG since it was on the "Chaowu" class general destroyer. At that time, it was referring to the model of dd-963 class of the United States. Considering that its full capacity is less than 4200 tons, which is almost half of the latter, rihai chose four "Spey" SMIA gas turbines from the traditional supplier R.R., with a total power of 39100kw. It can solve the contradiction between the quiet environment of high-speed pursuit of nuclear submarine and low-speed towed linear array sonar. When the new "village rain" class was built later, because the full discharge increased to 5100 tons, more power was needed to ensure that the speed could reach 30 knots. Therefore, two of the main engines were replaced by lm2500 with higher power, in order to keep the original characteristics in the case of increased displacement. The "high wave" class basically "copies" such a mode: four main engines are installed in two power cabins respectively, and the general layout of front and rear port and starboard is adopted. The first engine room is arranged on the front port side, with No.1 and No.2 engines built in to drive the left propulsion shaft. The second engine room is arranged on the starboard side of the rear, with No. 3 and No. 4 engines built in to drive the right propulsion shaft. 1. Unit 4 is lm2500 proced by GE; 2. Unit 3 is sm1c proced by R.R. The advantages of this arrangement are: first, it improves the anti damage ability of the aircraft; second, as a cruiser, sm1c has lower fuel consumption and noise than lm2500; its navigation quietness and enrance are better than "Chaowu"; third, the total power is 44400kw when the vehicle is combined to ensure that the maximum speed is 30 knots, meeting the needs of pursuing submarines[ [editor's note] the antisubmarine capability is the same as that of the "high wave" class. In the general layout and power plant selection, the 054A attaches great importance to the quiet environment required for the low speed towed linear array sonar's submarine search time outline, and the corresponding development work is carried out, and the goal is basically achieved through various efforts. The common equipment and use of ball bow active intermediate frequency sonar and towed linear array towed sonar can search and lock nuclear submarines and quiet diesel electric submarines. At the same time, the imported Ka-28 antisubmarine helicopter has a complete set of relatively perfect antisubmarine detection equipment. It is equipped with a small sea search radar under the nose. In addition to detecting sea targets, it can also detect submarines in the ventilation tube state. There is a special ordnance cabin under the fuselage, a vgs-3 active low frequency suspended sonar, and a magnetic detector at the rear of the fuselage
in addition, as early as the 054 basic model, the Chinese Navy for the first time has a complete and systematic anti submarine equipment on the frigate. In a sense, it has basically reached or approached the level comparable to the "high wave" class. By the end of 054A, it has realized the rocket assisted torpedo with hot vertical firing, and has the potential to become a professional anti submarine ship. It is similar to the Ka-28 anti submarine helicopter (which can carry the former Soviet Union's anti submarine helicopter specially designed to deal with us made nuclear submarines) АПР-ЗЭ Air anti submarine torpedo, Yu-7 324mm light anti submarine torpedo and 3200 6-Tube rocket deep bomb launcher constitute three anti submarine fire strike networks in the far, middle and near,

9. Hello, friend! Because the 571 Yuncheng missile frigate belongs to the 054A missile frigate, its standard is built according to the 054A missile frigate standard. Next, I will refer to the 571 Yuncheng missile frigate with the 054A missile frigate data. 054A Jiangkai improved missile frigate brief introction: 054 series anti submarine frigate is China's first stealth frigate that has really formed mass proction. The 054A anti submarine frigate has strong air defense and anti-ship capability, but it still lags behind the traditional naval powers such as Japan and the United States in the core technology and displacement, such as power system, general heat vertical generator, etc. After entering the 21st century, China has launched several new types of frigates. In addition to the 052B / C missile destroyer of Jiangnan Shipyard, Hudong Zhonghua shipyard in Shanghai and Huangpu shipyard in Guangzhou have also started to build the latest 054 frigates. The first ship of ship No. 525 was launched in Shanghai Hudong factory in December 1999 and launched on September 11, 2003, named Ma'anshan; The second ship was built by Huangpu factory in Guangzhou and launched on November 6, 2003, named Wenzhou
