advantages of digital currency:
1. Save cost and improve efficiency
in the traditional electronic payment process, funds are stored in the third-party platform. The third-party platform deposits funds through the time difference of payment to obtain short-term interest income, which makes customers and businesses suffer losses, and the transaction process has two capital transfers, which makes the transaction process rendant. Electronic payment based on blockchain technology eliminates the third-party platform and realizes peer-to-peer payment (P2P), which simplifies the payment process and reces the payment cost
2. Optimize the traditional payment function
digital currency can inherit the advantages of cash payment (point-to-point payment, instant payment and settlement, convenient and fast), and solve the defects of cash at the same time. In this condition, controllable anonymity can be realized at the same time. That is to say, compared with traditional mobile payment, digital signature is used to effectively protect the personal information of each participant, so as to prevent the loss, leakage or malicious tampering of the user's personal information
3. Control the whole life cycle of currency and control the return of currency
The economist Stiglitz studies the macroeconomic management of e-money system, and points out that the electronization and digitalization of money will help to improve the ability of central bank to monitor money flow and organize market, and improve the effectiveness of monetary policy. More importantly, legal digital currency will create a new price based monetary policy tool, which can break the zero interest rate lower limit and release monetary policy space Digital currency does not rely on physical outlets and labor services, and has low cost of infrastructure and human resources. It can obtain a larger service capacity with less material and human input, which is concive to the expansion of financial services in remote and poor areas. Moreover, financial services based on digital currency have the characteristics of small amount and convenience, such as "massive transactions, small and micro single amount", which create conditions for the general public to facilitate life and increase employmentIn recent years, digital currency has appeared frequently in the public's view. Shenzhen Luohu has also followed the trend and announced the release of 10 million digital red envelopes. How can we get the digital red envelopes this time
this activity is aimed at the vast number of indivials in Shenzhen. The total amount of RMB 10 million will be issued, with 50000 red envelopes and 200 yuan each
after receiving the digital red envelope, more than 3000 merchants in Luohu District can freely use it within the validity period of the digital red envelope. However, digital RMB can not be lent to others or cashed directly, and the digital currency will be withdrawn if it exceeds the validity period
it can be said that this way of giving back to the public is also a way to promote regional economic development. In the future, more and more places will use the Internet, and electronic red envelopes will become the mainstream
therefore, the way to get the red envelope is still very simple, but the probability of winning the prize is not very high, so it's time to rely on luck. I hope that all the little friends who read this article will have good luck and get a big red envelope of 200 yuan

electromagnetic frequency
in addition, RF is the abbreviation of radio frequency, which means the electromagnetic frequency that can be radiated into space, and the frequency range is from 300kHz to 30ghz
RF for short, RF is RF current, which is short for high frequency alternating electromagnetic wave. The alternating current that changes less than 1000 times per second is called low frequency current, and the alternating current that changes more than 10000 times is called high frequency current, and the radio frequency is such a high frequency current. CATV system uses radio frequency transmission mode
in the theory of electronics, when current flows through a conctor, a magnetic field will be formed around the conctor; When alternating current passes through a conctor, an alternating electromagnetic field is formed around the conctor, which is called electromagnetic wave
when the frequency of electromagnetic wave is lower than 100kHz, the electromagnetic wave will be absorbed by the surface and cannot form effective transmission. However, when the frequency of electromagnetic wave is higher than 100kHz, the electromagnetic wave can propagate in the air and be reflected by the ionosphere at the outer edge of the atmosphere, forming long-distance transmission capability. We turn the high-frequency electromagnetic wave with long-distance transmission capability into radio frequency, Abbreviation: RF
molates the telecommunication information source (analog or digital) with high frequency current (am or FM) to form RF signal, which is transmitted to the air through the antenna; After receiving the radio frequency signal in a long distance, it is demolated and restored to an electric information source. This process is called wireless transmission
wireless transmission has developed for nearly 200 years, forming a large number of users and proct groups. However, e to climate change and the impact of surface obstacles, it can not transmit perfect information
in modern times, people invented cheap high-frequency transmission cable (RF line). In order to pursue perfect information transmission quality and take into account the original wireless equipment, wireless wired transmission has become popular. The concept of radio frequency transmission came into being
if your information source is molated twice and transmitted to the opposite end by cable, and the opposite end restores the information source by anti molation before application, no matter how low the frequency is, it is also a radio frequency transmission mode. If there is no process of molation and anti molation, it is just to transmit the information source by cable to the opposite end for direct use, no matter how high the frequency is, it is a general wired transmission mode
RF in analytical chemistry
the ratio of the distance from the original point to the origin of the spot and the distance from the solvent front of the origin in thin layer chromatography
is a parameter of a method to indicate the moving position of components in chromatography. It is defined as the ratio of solute migration distance to mobile phase migration distance. Under certain chromatographic conditions, the RF value of specific compounds is a constant, so it is possible to identify compounds according to the RF value of compounds< br />Rf=distance moved from origin by component ÷ Distance moved from origin by solvent)
calculation method:
power sensitivity (DBM, dbmv, dBuV) DBM = 10log (pout / 1MW), where pout is the power value in MW
dbmv = 20log (Vout / 1mV), where Vout is the voltage value in MV
dBuV = 20log (Vout / 1uv), where Vout is the voltage value in UV
conversion relationship:
pout = Vout × Voit / R
dbmv = 10log (R / 0.001) + DBM, R is the load impedance
dBuV = 60 + dbmv application example calculation of wireless communication distance
3. [image authorization mode]
RF (royalty free) royalty free use mode, also known as royalty free use right mode,
defined as RF mode pictures, the use authorization obtained by users has the characteristics of non exclusive authorization. After the user purchases the use license, the use of the picture is not limited by the number of times, time, space and purpose. The authorized price of RF procts mainly depends on the size of the picture, not on the specific use. Once the user has purchased the RF image proct, it can be used for multiple purposes in multiple times without paying any additional fees (of course, illegal uses are prohibited). RF image procts are only for the buyer's own use, can not be transferred or sold again, and can not be bought out of exclusive use
RF mode authorization and pricing standardization, because of its "one purchase, multiple use" characteristics, has also been welcomed by many customers.
