What is the amount of digital currency

1.

The digital currency of the central bank is DCEP

the name of the digital currency developed by the central bank is DCEP (digital currency electronic payment). DC is digital currency. EP is electronic payment. Payment transmits digital things through a certain way, not paper currency. Therefore, electronic payment itself has the attribute of digital currency

The characteristics of digital currency are: low transaction cost; Fast trading speed; Highly anonymous

Application of digital currency

I. fast, economic and safe payment and settlement

cross border payment helps RMB internationalization. In 2015, the settlement volume of cross-border payment involving current account is about 8 trillion yuan. To accelerate the internationalization of RMB, cross-border payment and settlement procts and solutions with low cost, high efficiency and low risk are needed

At present, there are still a lot of repetitive human work in the bank's electronic loan process and processing process, and as the basic support of loan issuance, many of the collateral has the situation of false pricing or multiple or even no collateral. We can consider using digital currency to price and track bank collateral:

3. Bill finance and supply chain finance

in recent years, various bill market businesses based on commercial bills have grown rapidly, and bill financing procts have become a hot area of Internet financing. However, about 70% of the current bill businesses in China are still paper transactions, Supply chain finance is also highly dependent on labor costs

2. I can't give you an accurate answer to this question because digital currency covers too many aspects. There is also the possibility that many new cryptocurrencies are born or die every day. Now the world's more well-known digital currencies are bitcoin, dogcoin, Leyte coin, bitstock, reborn coin, Yuanbao coin, Diandian coin and so on. It is said that Ecuador, a small South American country, recently created its own official cryptocurrency
according to incomplete statistics, more than 200 counterfeit coins have been proced since 2014, and more than 100 have survived. The life cycle of Shanzhai coin is generally about 2-3 months. Because the purpose of some Shanzhai coins is to earn money without any innovation. When the price is high enough, the makers will sell a lot to cash out. Without the support of the makers, this kind of counterfeit money will eventually die.

3. You have said that digital currency and RMB are 1:1 equal use, then 10 million digital currency, of course, can be converted into 10 million RMB

4. 500 kinds

6. The most secret silver is in the wasteland and the otank valley. If you can collect all the secret silver, you can go to the insect nest in the lower left corner of gakison.
there are East West plague and burning plains in sainganglo.

high explosive bombs are made by engineering. You are calling for a comprehensive project to send you a formula. You can provide him with raw materials and give him some gold handicrafts

7. It should be one yuan fund
in July 2015, one yuan fund obtained the registration certificate of private equity fund manager issued by China Securities Investment Fund Instry Association, registration number: p1017159. It is a legal and compliant management company engaged in private equity investment
if one yuan fund refers to digital currency, it should be cautious. It may only be under the guise of digital currency. The real digital currency is cryptocurrency with a good application scenario planning, such as bitcoin, Ruitai coin, Laite coin, Qianjin card, etc.

To calculate the helical gear parameters, you need to know the basic parameters:

normal molus M_ n. Number of teeth Z, normal pressure angle α_ n. Helix angle β

generally, the crown height coefficient h * is 1, and the root height coefficient C * is 0.25. If there is displacement, it is necessary to calculate the displacement: x

the following is the basic parameter

end face molus: M_ t=m_ n/cos β

Calculation formula of pressure angle at the end face: Tan α_ t)=tan ( α_ t)/cos( β)

diameter of dividing circle: D = m_ n × z/cos( β)

addenm circle diameter: no displacement: Da = D + 2 × m_ n × H * with displacement: Da = D + 2 × m_ n × H * + x)

root circle diameter: no displacement: DF = D-2 × m_ n ×( H * + C *) with displacement: DF = D-2 × m_ n ×( H * + C * - x)

diameter of base circle: DB = D × cos α_ t)

in addition, there are more important dimensions, such as normal pitch, end pitch, etc., which can be obtained by referring to relevant manuals

Extended data:

judgment of helix rotation direction: first, we make the gear axis vertical, if the right height of helix is right rotation; On the contrary, the height on the left side of the helix is left-handed

end face and normal surface parameters:

end face: the plane perpendicular to the gear axis, and the parameters on the end face are generally added with subscript t

normal plane: the plane perpendicular to the helix, and the parameters on the normal plane are generally subscript n

(1) pitch and molus: = t= π

(2) pressure angle: generally, the parameters in normal plane are standard parameters

The correct meshing condition: the helix angle must be equal in size and opposite in direction. The normal molus m is equal to the normal pressure angle

B. geometric dimension calculation: in calculation, the calculation formula of spur gear can be directly applied to the end face of helical gear because a pair of helical gear transmission is equivalent to a pair of spur gear transmission on the end plane

there are many kinds of gear transmission, among which the efficiency of helical gear is very high, for example, the efficiency of spur gear transmission is lower than that of helical gear transmission

Like spur gear mechanism, helical gear can be used to improve the load capacity of transmission by recing the center distance a, which can be used for high-speed operation. Helical gear recer is a new type of recer. The helical gear recer is small in volume, light in weight and good in economy

Advantages:

(1) good meshing performance: the meshing process between helical cylindrical gears is an excessive process, and the force on the teeth is graally from small to large, and then from large to small; Helical gear is suitable for high speed and heavy load

(2) large coincidence degree: the increase of coincidence degree can improve the bearing capacity of gear. So the life of the gear is prolonged. The coincidence degree mainly depends on the meshing time, while the long meshing time and large contact area of helical gear rece the stress. The transmission is stable and the economy is increased

(3) compact structure: the less the minimum number of teeth, the more compact the structure

9. Digital currency and RMB have the same value. One yuan of digital currency is equal to one yuan of RMB. Their area is equal.

10. Token is just token in English, also known as token. It generally refers to the digital currency issued based on blockchain technology. When you say 200000 token, you don't specify the specific token type, such as bitcoin or Ethereum, EOS, or Monroe, etc. bitcoin now costs about 24300 yuan and Ethereum 800 yuan, so it depends on what token it is
