2. Three safety factors of E-bike: speed, weight and strength
1. Speed: in the new national standard of 2013, the maximum speed is no more than 26 km / h. Give consideration to speed and safe speed, so that travel more assured
2. Vehicle weight: in the new national standard, the vehicle weight is not more than 55 kg. It is divided into three grades, of which the intelligent type is 40kg, the auxiliary type is 50kg and the electric type is 55kg. The heavier the body, the better the safety
3. Strength: refers to the firmness of the frame. Thin body, poor stability, small wheel contact area, low friction coefficient, long braking distance, in case of accident, it is often too late to brake. On the contrary, good quality electric vehicles can effectively rece the safety risk
the Shenzhen Liaison Office of Guangdong bicycle and Electric Vehicle Instry Association believes that there are some misunderstandings about e-bikes among the public, including some laws and regulations and the media's over emphasis on speed and vehicle weight while neglecting other hardware factors such as frame firmness and software factors such as safety awareness.

3. This is a 25 cent commemorative coin in circulation, belonging to the series of 50 states and overseas territories in the United States
the $25 in the Mariana Islands is the sixth and last commemorative coin in the six SAR and territory commemorative coin program. The design of the coin uses images derived from the history and natural resources of the islands
near a tropical coast stands a huge latte, a huge limestone pillar used by the ancient Chamorros to support buildings. A boat of a native of the Northern Mariana Islands demonstrates the ability of the local people to sail. Two white terns are flying overhead. A bunch of flowers surround the bottom of the design. The local people call this flower "mwar", which symbolizes the virtue of honor and respect
the archipelago was ruled by the Spaniards for centuries, until they sold it to Germany in 1899. Japan seized the island in 1914, and American troops conquered them in World War II. After the war, the island belonged to the U.S. Pacific island territory, which ended in 1986. Local residents made a choice in 1975 to make the islands the common wealth of the United States, and President Ford signed a document to establish the "territory of the Northern Mariana Islands" the next year. Most of the islands in the southern part of the Mariana island chain, such as Guam, have applied for independent territories. The $25 is the third in the series.

4. The legal currency of the people's Republic of China is RMB. The people's Bank of China is the national authority in charge of the management of RMB and 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. Since the issuance of RMB, the people's Republic of China has lasted for more than 50 years. With the development of economic construction and the needs of people's life, it has graally improved and improved. So far, it has issued five sets of RMB, forming a multi variety and multi series monetary system of paper money and metal money, ordinary commemorative money and precious metal commemorative money. Except for 1, 2 and 5 cent coins, the first, second and third sets of RMB have been withdrawn from circulation. The current circulating RMB is the fourth set of RMB issued by the people's Bank of China since 1987 and the fifth set of RMB issued in 1999. The two sets of RMB are in circulation at the same time< On December 1, 1948, the people's Bank of China established and issued the first set of RMB, with 62 editions of 12 denominations, including 2 yuan bonds, 4 yuan bonds, 4 yuan bonds, 7 yuan bonds, 7 yuan bonds, 7 yuan bonds, 10 yuan bonds, 5 yuan bonds, 6 yuan bonds, 6 yuan bonds, 5 yuan bonds, 4 yuan bonds, 5 yuan bonds, 4 yuan bonds and 2 yuan bonds

the unified issuance of RMB is a major measure taken to meet the national liberation. It eliminated all kinds of currencies issued by the Kuomintang government, ended decades of inflation under the Kuomintang rule and China's nearly 100 years of history of foreign currency, gold and silver currency trading in the market, and promoted the overall victory of the people's Liberation War, It played an important role in the early period of economic recovery<

the second set of RMB

was issued on March 1, 1955, and the first set of RMB was recovered. The conversion ratio between the second set of RMB and the first set of RMB is 1:10000. The second set of RMB has 11 denominations, including 1 Fen, 2 fen, 5 fen, 1 jiao, 2 jiao, 5 jiao, 1 yuan, 2 yuan, 3 yuan, 5 yuan and 10 yuan. There are 2 kinds of 1 yuan vouchers, 2 kinds of 5 yuan vouchers, and 2 kinds of notes and coins for 1 Fen, 2 fen and 5 fen vouchers. In order to facilitate circulation, three kinds of coins, one cent, two cent and five cent, have been issued since December 1, 1957, which are equivalent to paper cents. On March 25, 1961 and April 20, 1962, black 1 yuan coupon and brown 5 yuan coupon were issued respectively to adjust and replace the face pattern and pattern. Due to the high technical requirements of large denomination banknotes, 3, 5 and 10 yuan were printed by the Soviet Union at that time

the second set of RMB has clear design theme, advanced printing technology, reasonable structure of main and auxiliary currency, and novel pattern color. The main scene pattern embodies the style of new China's socialist construction, the fighting course of the Communist Party of China's revolution and the theme of great unity of the people of all ethnic groups. In the printing process, in addition to the Fen coin, all other coupons are overprinted with rubber concave. The gravure plate is made by the traditional manual carving method in China, with a unique national style. Its advantages are deep pattern, thick ink layer, and good anti-counterfeiting and anti-counterfeiting function

the third set of RMB was issued on April 20, 1962. There are 7 denominations and 13 editions of the third set of RMB, including 1 jiao, 2 jiao, 5 jiao, 1 yuan, 2 yuan, 5 yuan and 10 yuan. Among them, there are 4 kinds of 1 jiao voucher (including 1 kind of coin), 2 jiao, 5 jiao and 1 yuan have 2 kinds of notes and coins. In 1966 and 1967, the 10 cents note was revised twice, mainly by adding full version watermark and adjusting the back color

the third set of RMB face design patterns reflected the policy of China's national economy at that time, which was based on agriculture, led by instry, and developed both agriculture and light instry. In terms of printing technology, the third set of RMB inherits and develops the technical tradition and style of the second set of RMB. In the process of plate making, the combination of machine and traditional manual makes the pattern and pattern fine; The ink color matching is reasonable, and the color is novel and bright; The paper width of the ticket is small and the design is beautiful< In order to meet the needs of economic development, further improve China's monetary system and facilitate circulation and transaction accounting, the people's Bank of China has issued the fourth set of RMB since April 27, 1987. There are 9 denominations of dime, dime and dime, 1 yuan, 2 yuan, 5 yuan, 10 yuan, 50 yuan and 100 yuan, of which dime, 5 yuan and 1 yuan have two kinds of notes and coins. Compared with the third set of RMB, it has increased by 50 or 100 yuan in large denominations. In order to meet the needs of anti-counterfeiting RMB work, on August 20, 1992, a revised version of the 1990 version of 50 and 100 yuan voucher was issued, adding a security line

the fourth set of RMB has certain innovation and breakthrough in design idea, style and printing process. Under the leadership of the Communist Party of China, the theme of building socialism with Chinese characteristics is embodied in the design of the main scene. In terms of design style, this set of RMB maintains and carries forward the traditional characteristics of Chinese national art. The pictures on the back of the main coin are drawn from Chinese historical sites and famous mountains and rivers, and the patterns on the back are all full of Chinese national characteristics. In the printing process, the main scene all uses a large number of head portrait watermark, the carving process is complex; Banknote paper adopts full page watermark and fixed portrait watermark, which not only shows the line picture, but also shows the level of light and shade. The technology is very high, which further improves the level of China's banknote printing technology and banknote anti-counterfeiting ability< On October 1, 1999, the people's Bank of China issued the fifth set of RMB in succession, with a total of eight denominations of 10 cents, 5 cents, 1 yuan, 5 yuan, 10 yuan, 20 yuan, 50 yuan and 100 yuan, of which 10 cents, 5 cents and 1 yuan have two kinds of notes and coins. According to the needs of market circulation, the fifth set of RMB increased the denomination by 20 yuan and cancelled the denomination of 2 yuan, making the denomination structure more reasonable

the fifth set of RMB inherits the traditional experience of China's printing technology and draws lessons from the advanced technology of foreign banknote design, which has greatly improved its anti-counterfeiting performance and adaptability to the modernization of currency processing. The front of each denomination currency adopts the head portrait of Chairman Mao Zedong in the early days of the founding of the people's Republic of China, the background adopts the Chinese famous flower pattern, and the back main scene pattern fully shows China's long history and magnificent mountains and rivers, and carries forward China's great national culture through the selection of representative patterns with national characteristics<

On the left side of the ticket are "Commemoration of the 29th Olympic Games", denomination number "10", Chinese pinyin "Yuan" and light holographic window safety line; On the top right of the bill are the name of the people's Bank of China in Chinese pinyin and the words and denominations of the people's Bank of China in Mongolian, Tibetan, Uygur and Zhuang languages
the Commemorative Banknote includes many anti-counterfeiting features: there are bright and variable denomination numbers on the top left of the front face of the note; There is a watermark in the blank area on the left side of the front face of the ticket; Holographically locate the hollow out logo on the lower left side of the front face of the ticket
in addition, the Commemorative Banknote also has anti-counterfeiting features such as two-color connection, special-shaped number, pearlescent pattern, light variable holographic window opening safety line, offset micro text, etc
the number of commemorative banknotes issued is 6 million. Commemorative Banknote has the same function as the current circulating RMB, and it has great potential for appreciation with the same denomination RMB. The reasons are as follows:

the number of issued currency is large, and the speculation factor is high.

in recent years, the circulation of low-grade currency is generally large. The larger the circulation is, the stronger the speculation is. There are almost a certain number of popular varieties that are easy to cause speculation in the currency market. Without enough quantity, it will not form a scale and a climate for speculation, This has become a major feature of China's post currency card market in recent years. Some senior coin investors have never been afraid of issuing a large number of varieties. They are only afraid that the market lacks themes and hot spots of speculation. Just like the 10 million "constitution" coins, the circulation is not small, but in the spring of 1997, did not they still reach a high of more than 60 yuan? In the current currency market environment with imperfect management and unreasonable operation, large circulation is just a rare advantage of speculation in a sense. Some circulating commemorative coins published in recent years have large circulation, unique design and theme, and all belong to the potential varieties with strong speculation<

good mass foundation and great social demand

in fact, a small circulation does not mean a large social demand, and the circulation of commemorative coins has become a popular public collection, which is concerned by the majority of coin collectors. A large social demand has become a major feature of circulation of commemorative coins, especially those issued late, with a large circulation of commemorative coins Varieties with low market prices are more likely to be welcomed by people

good design and low market price

since the spring of 1997, the price of commemorative coins in circulation has plummeted. Although there were several small rebounds ring this period, it is difficult to become a climate. Nowadays, the circulation of commemorative coins, especially the low-grade commemorative coins issued in recent years, not only have good topics, new design and good proction, but also their prices have fallen seriously. Looking at the current coin market, the author thinks that the space for these low-grade commemorative coins to fall further is only 10%, while the space for them to rise is 100%, or even higher

2008 will be a year when commemorative coins will bloom everywhere. The big market has just begun. We should make good use of the once-in-a-lifetime opportunity of the 2008 Olympic Games. The opportunity is only for those who are prepared to take practical actions and welcome you with fruitful results

5.

The material and weight of real gold and silver coins are made of pure gold and silver, and the weight tolerance and dimension tolerance are strictly controlled; Most of the counterfeit gold and silver commemorative coins are made of copper and low fineness silver

2, special anti-counterfeiting process

for specific precious metal commemorative coin projects, there are special anti-counterfeiting processes, including invisible carving, laser illusory color, color changing ink, oblique wire teeth, full tooth interval half teeth, etc., showing a unique effect. The counterfeit precious metal commemorative coins do not have similar anti-counterfeiting technology or the anti-counterfeiting pattern is not clear, so consumers can identify them by referring to the announcement issued by the people's Bank of China

3. Color printing effect

the genuine color precious metal commemorative coin has full color, uniform ink distribution, accurate alignment with the relief on the bottom, and no offset or exposure. The ink distribution of counterfeit colored precious metal commemorative coins is uneven, and it is easy to appear color deviation, white and other phenomena

On August 20, 2015, the people's Bank of China decided to issue a set of commemorative coins for the 70th anniversary of the victory of the Chinese people's war of resistance against Japan. The main design on the front of the commemorative coin is the national emblem, which shows that the commemorative activity of this national, world-famous and significant historical event was held in the name of the country. The year number "2015" below shows the issuing time of commemorative coins and the year of commemorative activities

the set of commemorative coins, including three gold and silver commemorative coins and one nickel clad steel commemorative coin, are legal tender of the people's Republic of China. Among them, 7.776 grams (1 / 4 ounces) of Gold Commemorative Coin 1; 1 silver commemorative coin of 31.104 g (1 oz.); 155.52g (5oz) Silver Commemorative Coin 1; One nickel clad steel commemorative coin

when the people's Bank of China issues commemorative coins, it will announce the plan of issuing commemorative coins to the public in advance, and when each project is issued, it will also announce the announcement of issuing commemorative coins to the public, which can be found on the website of the people's Bank of China. The information of these commemorative coins should be fully understood and carefully selected in advance. Don't trust some false propaganda to avoid being deceived

6. If it can be detected that the piece is broken, just replace it. Generally, the four small batteries of electric vehicles will not break together. My father's electric vehicle is broken. I spend 50 yuan to replace the broken one with a good one. It's OK to install it. It's very simple. Otherwise, it will cost more than 500 to replace the new battery, which is also a waste!

7. It is feasible in theory
battery discharge / charge mode switching can be set at high speed or downhill. Convert kinetic energy into electricity

in fact, some electric vehicles already have such designs. When deceleration is needed, the complex structure automatically switches the working mode, and the permanent magnet installed on the wheel cuts the back EMF proced by the magnetic line of force to slow down the vehicle, rather than only through the traditional brake pad friction deceleration

however, e to the fact that the speed of the bicycle is not very high, the energy that can be converted ring deceleration is relatively small, the deceleration time is not too long (mainly depends on the friction of the brake pads to decelerate quickly), and the downhill situation is not very frequent. Considering these factors and the requirements of the simplified design of the bicycle itself, it is not worth the cost to increase the facilities for converting electric energy, or it has little effect.
