What does virtual currency letter conversion represent

1.

1. RMB - RMB

the legal currency of the people's Republic of China is RMB, and the people's Bank of China is the national authority in charge of the management of RMB, which is responsible for the design, printing and issuance of RMB

the unit of RMB is yuan, and the subsidiary units of RMB are Jiao and Fen. One yuan is ten Jiao, and one Jiao is ten Fen. The first letter of the alphabet of RMB is capital Y with two horizontal lines, that is "&#"

2. U.S. dollar; ISO 4217 currency code: USD; Symbol: USA $) is the legal tender of the United States of America. The US dollar banknotes in circulation at present are all kinds of banknotes issued since 1929

In 1792, the coinage act of the United States was passed. The current issue of dollars is controlled by the Federal Reserve. Since 1913, the United States has established the Federal Reserve System and issued Federal Reserve bonds. More than 99% of the banknotes in circulation are Federal Reserve notes

Japanese yen - JPY

yen (Japanese: 円, Japanese Roman: en, English: yen), whose banknotes are called Japanese bank notes, is the legal currency of Japan, and Japanese yen is often used as reserve currency after US dollar and euro. The currency code is JPY

Japanese yen is the name of Japanese currency unit, which was founded on May 1, 1871. In 1897, Japan established the gold standard system, and the gold content was set at 0.75 g. in May 1953, the gold content was announced to be 0.00246853 g. on March 31, 1988, the gold standard system was completely abolished

there are four banknotes in circulation, namely, 1000, 2000, 5000 and 10000 yen, and six coins in denominations of 1, 5, 10, 50, 100 and 500 yen

4. Euro - the euro is the currency of 19 countries in the European Union. The 19 member states of the euro are Germany, France, Italy, the Netherlands, Belgium, Luxembourg, Ireland, Spain, Portugal, Austria, Finland, Lithuania, Latvian, Estonian, Slovak, Slovenian, Greek, Maltese and Cyprus

on January 1, 1999, the single monetary act was implemented in the European Union countries implementing the euro. In July 2002, the euro became the only legal currency in the euro area

the euro is managed by the European system of central banks (ESCB), which is composed of the European Central Bank (ECB) and the central banks of the euro area countries

5, pound sterling - GBP

pound sterling is the name of the national currency and monetary unit of the United Kingdom. Sterling is mainly issued by the Bank of England, but there are other issuers. The most commonly used symbol for pound sterling is & #;. The ISO 4217 currency code adopted by the international organization for Standardization for pound sterling is GBP (Great Britain pound). In addition to the United Kingdom, the currency of the British Overseas Territories is also in pounds, and the exchange rate with the pound is fixed at 1:1

as Britain is the first instrialized country in the world and once dominated the international financial instry, pound sterling used to be the most widely used currency in international settlement business

2. According to the roadmap published on the official website, there are two major branches, one is the expansion of underlying functions, the other is the optimization of user experience. The underlying function expansion is mainly to develop new functions on the basis of peer-to-peer payment to support the long-term vision of a real Internet of value (IOV). For example, expand Op_ Return, optimizing the cache architecture for balance, anonymity on the chain, and native protocol component based on op code are designed to support the implementation of functionality
there are two main reasons why user experience optimization is listed separately. First, LBTC wants to build an excellent peer-to-peer e-cash system. Its basic idea is to put payment experience and user first, so it puts it at a high level, such as cross platform light wallet, accelerating payment confirmation speed, optimizing irreversible block mechanism, etc. Second, LBTC has always emphasized superior chain governance system. Before that, there was a standardized SGS (spark governance system) governance system, but it still needs to constantly improve the relevant mechanisms. For example, we should greatly optimize the node parameters and election mechanism, establish the LBTC foundation, multi-channel proposal process, and light wallet's support for the governance function on the chain.

f=N μ N is the positive pressure, that is, the pressure acting on the contact surface, μ It is the dynamic friction coefficient, which refers to the influence factors of the roughness of the contact surface on the friction. Or use the balance f = f; It's only used when it's stationary or moving in a straight line at a constant speed, but it's the most used in junior high school

the so-called friction is the force that hinders the relative motion of the object, and the direction of friction is opposite to the motion direction or relative motion direction of the object. The conditions of friction are as follows:

(1) two objects must contact each other

(2) there was extrusion between two objects

(3) there is a tendency of motion or relative motion between two objects

If an object is stationary on a horizontal plane, it will not be affected by friction if it is not pushed or pulled. If thrust or pull is received, it belongs to the category of static friction. The size of friction is equal to that of pull or thrust, and has nothing to do with the gravity or pressure of the object. Only the maximum static friction is related to the pressure or gravity on the object

if the object is not pushed by 10N force, the object will be subjected to static friction, which is equal to the thrust. Just push with 15N force, and the friction force on the object is the maximum static friction force. If the thrust force is increased later, the friction force will not change. Theoretically, the sliding friction of objects is less than the maximum static friction, but it is generally considered that they are equal

The friction force is f = 15-10 = 5N

extended data:

methods to increase beneficial friction

(1) increase the roughness of contact surface

(2) increase the pressure

(3) change rolling friction into sliding friction

(1) replace sliding friction with rolling friction

(2) make the contact surface separate [form a layer of air cushion or magnetic suspension on the contact surface of the object]

(3) decrease the pressure

(4) rece the roughness of the contact surface

In engineering technology, people often rece friction by applying lubricating oil. The science of this problem is called tribology, which is a branch of mechanical manufacturing

If two objects, which are in contact with each other and squeeze each other, but relatively still, only have a relative sliding trend under the action of external force, but do not have relative sliding, then the force between their contact surfaces hindering relative sliding is called "static friction". When the static friction increases to the maximum, the object will move

size: the static friction varies according to the external force, but there is a maximum value, which is called the maximum static friction. The maximum static friction is slightly greater than the sliding friction

direction: tangent to the contact surface, opposite to the direction of relative motion trend

On the basis of a large number of experiments, G. amunton and C. - A. de Coulomb proposed the following law of friction in 1699 and 1781:

① the friction between two objects in contact does not exceed a certain maximum value, which has nothing to do with the size of the contact area

(2) the maximum value of friction is proportional to the normal pressure n between two objects

(3) the direction of friction is opposite to the sliding direction of the object, and its magnitude is directly proportional to the normal pressure n between the two objects

the above conclusion is only a rough empirical rule, but because it was found in the early days of mechanical science, it was called the law of friction, also known as Coulomb's law

5. Anyone who knows the current Internet situation knows that at present, the domestic Internet has been basically monopolized by bat, and several mountains of traditional Internet have been placed in front of us. It is very difficult for young entrepreneurs to keep pace with it, let alone surpass it! Compared with the commercial connection of traditional Internet, blockchain instry is just a "big town fair", and everyone has the opportunity to develop. Now there are many blockchain + projects. There is a SMIC blockchain service platform project launched by the blockchain Instrial Park of Changsha high tech Zone, which is a blockchain application landing project and a blockchain + public service mode, Enterprises are being solicited to join the chain.

7. It depends on the ultimate goal of the hacker. Hackers attack website is generally to paralyze the system, so that it can not work normally according to the designer's intention. If the hacker hacked a system and changed his target, that is to say, the hacker links the website that the visitor wants to visit to other websites. If the connected website is full of malicious, then your visit is very dangerous.. In general, the virus is tied to the file to access, if you do not conct a special antivirus scanning process, it is difficult to be found.. Don't put too much hope in the firewall...

8. It's a P2P platform, and now these platforms have greater financial risks.

9. The cat you are talking about is called modem, which is also called modem. It is a necessary hardware device to access the Internet through telephone dialing. Generally, the internal use of the computer is "digital signal", while the signal transmitted through the telephone line is "analog signal". The function of modem is to convert the digital signal used in the computer into the analog signal which can be transmitted by telephone line when the computer sends information, and send it out through the telephone line; When receiving information, the analog signal from the telephone line is converted into digital signal and transmitted to the computer for receiving and processing. So you can't just plug in

10. Domestic uranium ore grade is very low, radiation intensity is not big, as long as you don't stay in the space with uranium ore for a long time, there should be no problem! There's no need to talk about nuclear discoloration!
