The impact of deflation on digital currency

1. Inflation is the price rise that causes the devaluation of a country's currency. The essential difference between inflation and general price rise: general price rise refers to the temporary, partial and reversible price rise of a certain commodity e to the imbalance of supply and demand, which will not cause currency devaluation; Inflation is a sustained, universal and irreversible rise in the prices of major domestic commodities that can cause the devaluation of a country's currency. The direct cause of inflation is that the amount of money in circulation in a country is greater than its effective economic aggregate
deflation is deflation: when the amount of money in circulation in the market decreases, the people's money income decreases, and the purchasing power decreases, which affects the prices and causes deflation. The long-term monetary tightening will restrain investment and proction, lead to the rise of unemployment rate and economic recession
these two are inflation and deflation respectively.

2. Huang Mitong said that Yesi is that if there is less money in circulation in the market, his price will rise, because it is the principle of economics that the rare is the most expensive.

Recently, the price of global crypto digital currency is quite unstable. Bitcoin has fallen below US $7000 from its peak of US $20000 at the end of last year, and soared by more than 11% in one day. There are huge fluctuations in the market, and there are many differences in the attitudes of countries towards digital currency. Some announced that they would issue the world's first sovereign legal digital currency, showing a "strong support" attitude, and more countries carefully observed and focused on research and guidance

the existing monetary and financial system is not a natural evolution, but an inevitable result of legal restrictions or government regulation. Although cryptocurrency has many defects, it is also a valuable experiment, especially in the exploration of super sovereign currency. Different from precious metal currency and credit currency, they are oriented to the exploration of "transaction benchmark consensus" in the data age. Of course, if it is affected by too much price fluctuation, speculation, deflation restrictions, etc., and the payment function of crypto digital currency can not be truly implemented, it can only be further and further away from the "currency experiment", or become a special basic "digital asset", or a flash in the pan in the long history

still want to cancel virtual currency< br />

4. 1. The impact of currency deflation on foreign exchange investment starts from the price first, and the impact of deflation on currency is more favorable, which also means that the fluctuation of market form of foreign exchange investment is more favorable, and more investment profit opportunities will appear. If there is currency deflation, there will be corresponding fiscal policy. If fiscal policy tends to adjust the situation of currency deflation, it may affect the proportion of capital in foreign exchange investment. Consumers may turn to other spot investments in order to ensure the value of their wealth, which will make the foreign exchange market cold and depressed
2. Currency deflation increases the wealth value of consumers, so that investors have more spare wealth to invest. Currency deflation promotes the foreign exchange market, so more people will choose foreign exchange investment to drive the development of the foreign exchange market, and successfully make the market volatility more favorable, which virtually provides more profit opportunities for investors
3. The above is the possible impact of currency deflation. The foreign exchange market is very big, and many factors may affect the market, thus affecting the investment of investors.

5. They have invested 300000 yuan, and some people have invested 1 million to 7 million yuan. The interest rate of zhaocaimao is not the highest. The interest rate of platform is much higher than that of zhaocaimao. However, the government has given zhaocaimao more honor. The victims believe in the government. Now they are in liquidation, and they have to pay the interest for three years. Before that, they didn't pay any interest, Moreover, the boss, Mr. Yuan, has been hiding from the victim and consulting a lawyer. Only one year or so can he get back the money. Three years of the platform is full of trust time. One year later, the victim will go bankrupt or run away. It's good that the victim can only get back one-third of the money, while the boss of the platform can be happy without paying back the money.

6. As an outstanding representative of command-line tools in win10, Microsoft intends to replace CMD with this tool to some extent. At present, it has been used as the default command-line tool for right-click menu of start button. This tool can be used to verify files, such as calculating MD5, SHA1 value, etc<

the specific methods are as follows:

1. Default normal verification (sha256) command:

get filehash file path | format list

2. Special requirements verification

get filehash file path algorithm verification content | format list

it home prompt 1: the verification does not support CRC32 (as shown in the figure above), The following are the authentication types supported by this command< br />
• SHA1

• SHA256

• SHA384

• SHA512

• MACTripleDES

• MD5

• Ripemd160

it home prompt 2: enter a similar D: &# 92 in the command line; When program files (x86) is used as the path, it will be difficult for the program to recognize it directly because of the characters such as spaces and brackets. Therefore, it is necessary to add double quotation marks before and after the path& quot;， This is not necessary for normal folder names

tip 3 of it home: the parameter algorithm cannot be specified more than once in the same command. Only one check value can be calculated for a command

if you want to quickly check multiple values, you can use the file master of soft media Rubik's cube (click to download), just drag the file into the program window.

7. Partition management
the principle of conventional hash and linear hash is the same. After adding and shrinking partitions, the original data will be redistributed according to the number of existing partitions. Hash partition cannot be deleted, so drop partition operation cannot be used to delete partition
partitions can only be merged by alter table... Coalesce partition num, where num is the number of subtracted partitions
you can add partitions by alter table... Add partition partitions num. here, null is the number of partitions added on the original basis
1. Merge partitions
subtract three partitions
alter table tblinhash coalesce partition 3< br />SELECT PARTITION_ NAME,PARTITION_ METHOD,PARTITION_ EXPRESSION,PARTITION_ DESCRIPTION,TABLE_ ROWS,SUBPARTITION_ NAME,SUBPARTITION_ METHOD,SUBPARTITION_ EXPRESSION
FROM information_ schema.PARTITIONS WHERE TABLE_ SCHEMA=SCHEMA() AND TABLE_ NAME=' tblinhash';

note: after subtracting the two partitions, the data is redistributed according to the existing partitions, in order to & # 39; 2003-04-14' For example: power (2, ceiling (log (2,3))) = 42003 & (4-1) = 3,3 & gt= 3,3 & (ceiling (3 / 2) - 1) = 1, so the present & # 39; 2003-04-14' This record changed from P3 to P1

2< br />SELECT PARTITION_ NAME,PARTITION_ METHOD,PARTITION_ EXPRESSION,PARTITION_ DESCRIPTION,TABLE_ ROWS,SUBPARTITION_ NAME,SUBPARTITION_ METHOD,SUBPARTITION_ EXPRESSION
FROM information_ schema.PARTITIONS WHERE TABLE_ SCHEMA=SCHEMA() AND TABLE_ NAME=' tblinhash';

when four partitions are added to the three partitions, the 񟭃-04-14' is changed from P1 to P3, and the other record is changed from P2 to p6

9. The answer is already in the above
this is the test question of CET-4 in 2013
the original question is
1dhcp: request, t ype:DHCPdiscover
2DHCP:Reply，T ype:DHCP 11
3DHCP:Request，T ype:DHCPRequest
4DHCP:Reply， T ype:DHCPACK
DLC: --- DLC: destination = [12]
DLC: source = 001122334455
DLC: Ethertype = 0800 (IP)
IP: D = [13], s = 192.168.0.1
[14]: D = 68, s = 67
the answers are
11: offer

12: ffffffffffff
13: 255.255.255.255
14: UDP
meaning
1-4 are the four packets in the DHCP process, Discover, preallocate, request, confirm

then the following is the link layer packet header
according to the information, the packet is DHCP offer
DLC: destination = ffffffffff; Link layer destination address (destination MAC address, because the client has no IP address at this time, it can only broadcast)
DLC: source = 001122334455; Link layer source address (source MAC address, MAC address of DHCP server network card)
DLC: Ethertype = 0800 (IP); Type (indicating that the Ethernet frame carries an IP packet)
IP: D = 255.255.255.255, s = 192.168.0.1; Source destination IP address (at this time, the client has no IP address, so broadcast is used, and the source address is the DHCP server address)
UDP: D = 68, s = 67; Source destination port (DHCP uses UDP, server port number is 67, client port number is 68)

10. Now the automatic plate and frame filter press is often used in instry. After filtration, the filter plate of the machine is compressed automatically by the hydraulic system. After filtration, the hydraulic system also realizes the pressing, plate opening, cake stripping and removal. The working efficiency of rotary filter press is much higher than that of ordinary filter. Although this kind of hydraulic control filter press can save labor and realize the automation of the filtration process, the additional hydraulic system takes up a lot of space, and still can not change the shortcomings of the ordinary plate and frame filter, such as short filtration cycle, low filtration rate and relatively small processing capacity. The rotary filter press can realize continuous filtration for a long time. The filtration cycle, filtration efficiency and material handling capacity are far more than those of ordinary plate and frame filter, and the floor area is small. As a plate and frame filter, to continue to use the machine for filtration after the filtration is terminated, the first step is to dismantle the filter plate and remove the filter cake, which is undoubtedly quite tedious work. Moreover, it is different from the common plate and frame filter press that the filter cake should be careful not to break when washing, otherwise the washing effect will be greatly reced. Its washing is completed in the process of continuous mixing and thickening inside the machine, and finally discharged from the slag discharge valve, so there is no need to worry about the "short circuit" problem of filter cake washing. Although the energy consumption is more, the rotary filter press is a better choice than the ordinary filter press in the filtration process with high added value, large material handling capacity and long filtration time. Moreover, the concentration of the concentrate discharged from the filter is quite high. Generally, the solid content is controlled at about 60%, sometimes it can reach about 70%, which is no less than the moisture content of the filter cake pressed by the ordinary plate and frame filter press. If it is necessary to concentrate the solid phase in the suspension, the proction efficiency of the rotary filter press is much higher than that of the ordinary plate and frame filter press. And it takes a lot of time.
