1. This is because bitcoin is recorded in the form of encryption. Based on the above reasons, the Chinese government does not allow bitcoin to circulate, fearing that bitcoin will compete with China's digital RMB.

2. It is the trend of the times for digital currency to replace paper money, which is the trend and necessity of social development. But at this stage, when digital currency comes out, paper money will not disappear. Although some countries in Eastern Europe are trying to de paper money, it is not fully realized. Moreover, these countries are highly developed countries with small land area and complete infrastructure
in China, the digital currency issued by the central bank will coexist with the paper currency for a long time, until the paper currency is graally replaced by the digital currency. Of course, digital currencies such as bitcoin, Leyte and decent can only exist as a supplement, and cannot become the mainstream.

3. Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"

all those who have made great achievements at all times and in all over the world are as good as gold at all times. The ancient book Huainanzi says: & quot; Sages do not value the wall of the ruler, but the Yin of the inch& quot; There is such a poem in changgexing, the Yuefu of Han Dynasty: & quot; When will all rivers return to the sea? If you don't work hard when you are young, you will be sad when you are old& quot; In Jin Dynasty, Tao Yuanming also had his poems of cherishing time: & quot; If you don't make a comeback in the prime of life, you can't make it in the morning. Just in time, you should be encouraged, and time will wait for no one& quot; In the late Tang Dynasty, Wang Zhen's poem "White Deer Cave" has more & quot; An inch of time is an inch of gold; It's a wonderful metaphor. Balzac, a French writer, compares time to capital. Goethe, a German poet, regards time as his own property. Lu Xun has a deeper understanding of time. He said: & quot; Time is life. Wasting other people's time for no reason is tantamount to murder& quot; After middle age, in order to save time, Faraday devoted his whole body and mind to scientific creation, strictly controlled himself, refused to participate in all activities unrelated to science, and even resigned as the president of the Royal College. Madame Curie never put a chair in the drawing room so as not to delay the visitors. Einstein, 76, fell ill. An old friend asked him what he wanted. He said, "I just hope there are still a few hours left for me to sort out some manuscripts."< However, do you know how much they cherish their time? As early as more than 200 years ago, before the independence of the United States, Franklin, the initiator, scientist, instrialist and one of the leaders of the independence movement of the United States, collected two popular and influential maxims in his book the road to wealth: & quot; Time is life& quot; Time is money;. In the early 1990s, the youth delegation of Liaoning Province of China attended a meeting in Japan. Before going abroad, the head of the delegation prepared a thick stack of speeches. However, at that time, the order sheet submitted by Japanese officials read: & quot; Speaking time of the Chinese side: 10:17:20 to 18:20& quot; The speaking time is only one minute. This is in those & quot; A cup of tea, a cigarette, a newspaper for a long time; It seems inconceivable to most people, but it is very common in Japan. From workers to scholars, Japan has a strong sense of time. Their basic criterion for assessing the incompetence of workers is the amount of labor per unit time on the premise of ensuring the quality, and the time is generally accurate to seconds<

Franklin, a famous American scientist, once said: "do you love life? Then don't waste time, because time is the material of life It is true that the value of a person's life lies in the value he creates for the society, but this kind of value is realized with the extension of time. Just imagine, which of the great masters of science and art who created a lot of material and spiritual wealth for human beings in history did not enrich and make sense of their lives by "sparing time"? Let's listen to their own experience first. Goethe is a famous poet all over the world. His autobiography is the best annotation of his understanding and feelings of time: "time is my property, my field."

to save time is to make a person's limited life more effective, which means to prolong his life

- Lu Xun

I think the most valuable thing in the world is "today", and it is also "today" that is easily lost. Because it is the easiest to lose, it is more valuable

- Li Dazhao must remember that our time for study is limited. Time is limited, not only because of the short life, but also because of the complicated personnel. We should try to spend all our time doing the most beneficial things

- Spencer

the more one knows the value of time, the more he feels the pain of lost time<

- Dante

Edison, the great inventor who influenced the world. He can't read until he is 12 years old. He only stayed in a regular school for three months. His math and reading and writing skills are very poor, and he can't concentrate. He is a trouble boy. He was dyslexic because of hearing loss as a child. All his life, he had difficulty in writing and spelling

Edison's earliest interest was in chemistry. He collected about 200 bottles and saved every penny to buy chemicals and put them in bottles. At the age of 12, he went to the train to sell newspapers to earn money

In 1861, the civil war broke out in the United States. Edison used the convenience of the train to run a tabloid to convey the war situation and information along the way. He is a journalist, editor, typesetter, proofreader, printer and distributor. The tabloids were popular, and he gained talent, knowledge and experience from his intense work. He also earned a lot of money to continue his chemical experiments

But unfortunately, when he was doing an experiment on the train, the train suddenly bumped, causing a piece of phosphorus to fall on the board and cause combustion. The conctor came to put out the fire and slapped him in the face, deafening his left ear. He was driven off the train when Edison was only 16 years old

The frustration didn't make Edison lose heart. He fell in love with telegraph again. After repeated research, he invented an automatic electric recorder in 1868, which was his first invention. Later he invented two new types of telegraph. In 1877, he invented the carbon telephone transmitter, which made the original telephone sound clearer; In addition, he invented the phonograph. People call him "the magician"

Edison died on October 18, 1931 at the age of 82. However, so far no one has been able to break his record of holding 1093 invention patents. People call him the king of invention

extended materials:

main achievements

first, phonograph

in 1877, Edison found that the diaphragm in the telephone transmitter would vibrate with the sound of the voice, so he took a short needle to do the experiment, and got a lot of inspiration from it. Edison asked his assistant to make a "strange machine" composed of a large cylinder, a crank, a receiver and a membrane plate

after it was made, Edison took out a piece of tin foil, rolled it on a metal cylinder with spiral grooves, and let one end of the needle gently rub the tin foil to rotate, and the other end was connected with the receiver. Then Edison shook the crank, sang to the receiver, put the needle back to its original place, and then shook the crank, and the machine played back Edison's voice

In December, Edison publicly displayed this "tin foil gramophone", which caused a sensation all over the world

The first inventor of electric light was not Edison, but Edison improved electric light. As early as 1801, a British chemist named Humphrey David used platinum wire to electrify light in his laboratory

In October 1879, Edison finally successfully made the carbon fiber filament incandescent lamp, which was called "carbon cotton filament incandescent lamp", and then put into mass proction, and set up a company to set up the power station and transmission network and other corresponding infrastructure, which soon made the electric lamp widely used in the United States

During the

period, he constantly improved his technology, and finally decided to use tungsten filament as the filament, which is called "tungsten filament lamp", and it has been finalized and used so far, so Edison has become a recognized inventor of electric lamp

Thirdly, in the aspect of film, there are

According to the main development trend of non-metallic mineral exploitation and utilization in the world and the current situation of non-metallic mineral resources and utilization in Henan Province, the development of non-metallic mineral instry in Henan Province must serve the economic construction of Henan Province and provide high-quality non-metallic mineral raw materials for the development of instry, agriculture and high-tech instry in Henan Province; At the same time, we should focus on the domestic and international markets, expand domestic and foreign sales, and increase the fiscal revenue of Henan Province. Give full play to the role of science and technology as the primary proctive force, strengthen the close cooperation between scientific research institutions, especially the National Research Center for comprehensive utilization of non-metallic mineral resources, luonai Institute, Sanmo Institute and other scientific research institutions, factories and mines, jointly tackle key problems, form a number of leading and exemplary achievements, and change the backward situation of only procing raw materials and primary processing procts as soon as possible, We should accelerate the transformation of non-metallic mining instry from simple labor-intensive to technological development, to the instrial development direction of deep processing procts, improve the economic benefits of factories and mines, and turn resource advantages into economic advantages

the nonmetallic minerals listed below are mainly developed in Henan Province from the 10th five year plan to 2010: ① kyanite, andalusite, sillimanite; ② Xinyang Shangtianti bentonite, perlite, zeolite, tuff and other non-metallic minerals; ③ Bauxite and refractory clay; ④ Graphite; ⑤ Rutile; ⑥ Sericite; ⑦ Nepheline syenite; ⑧ Natural alkali

in Henan Province, the following instries should be developed

In addition to large reserves, Henan Province also has a complete range of refractory minerals, including high alumina clay, hard clay (coke gem), soft and semi soft clay, bauxite, etc., as well as kyanite, bauxite, etc., which can be used to proce high-quality and special refractory materials Sillimanite, andalusite, forsterite and so on. At present, a proction scale of 2.5 million tons of raw ore and 1.5 million tons of refractory has been formed. However, the resources available for development and utilization are seriously insufficient, because there are more reserves of low-grade ores and less high-grade ores with high quality. Some foreign trade export units and refractories factories purchase high alumina mature materials with Al < sub > 2 < / sub > o < sub > 3 < / sub > content more than 85%, and aluminum factories only collect rich ores with Al / Si ratio greater than 8-10, which will inevitably lead to indiscriminate mining, with mining rate of only 30% - 40%, rapid rection of high-quality high alumina clay, destruction and waste of resources. In the face of this phenomenon, in addition to strengthening the administrative management of government departments, conscientiously implementing the "mineral resources law of the people's Republic of China" and making overall planning for resource development, it is more important to strengthen the research on Beneficiation and purification process of low and medium grade ores (al < sub > 2 < / sub > o < sub > 3 < / sub > content below 60%) to supplement the shortage of high-quality and high-grade ores, It not only ensures the sustainable and healthy development of refractory instry, but also ensures the demand of High Alumina ore for high alumina cement and alumina proction

The key to improve the quality of refractory clay mineral procts in our province is to rely on the progress of science and technology and improve the proction technology and equipment level of mining, beneficiation and calcination. In order to ensure the stability of ore supply and the quality of ore, measures such as homogenization should be taken to rece the mixed grade in the mining process. Improving calcining furnace and adopting advanced calcining furnace are important measures to improve the quality of refractory clay clinker. In the calcination proction, we should graally eliminate some earth shaft kilns with small diameter and small height difference between inlet and outlet, transform and popularize large calcination shaft kilns with diameter greater than 3.0m and height difference between inlet and outlet of 10m, and build some downdraft kilns with the diameter of 100m < sup > 3 < / Sup > or above or 0.3m in places where conditions permit × 60m rotary kiln, so that the quality of calcined clinker continues to improve, in order to enhance market competitiveness

depending on the progress of science and technology, the refractory clay proct structure of our province should be updated. High quality high alumina clay resources (DUJIAGOU, JIAJIAWA, etc.) should be further processed to proce high quality high alumina hard refractories such as magnesia alumina spinel and mullite

In view of the current situation of low concentrate grade, low recovery and poor economic benefit, it is necessary to strengthen the research on "three stone" beneficiation process. The concentrate grade of Kyanite in acidic pulp beneficiation process is higher than that in alkaline pulp beneficiation process, but the equipment is seriously corroded. Desliming operation takes away part of fine Kyanite and reces its recovery. The reagent system of alkaline pulp beneficiation process is more strict than the former, which has poor adaptability to the ore. in order to ensure the concentrate grade, sometimes the grade of the selected ore has to be increased, thus increasing the beneficiation cost. There are similar problems in the processing of sillimanite and andalusite, so it is very important to study the "three stone" processing technology in Henan Province

In the future, we should take Yinshan kyanite, Neixiang, Zhenping, Tong sillimanite and Xixia andalusite as the development objects, focus on the research on the technological characteristics of "three stone" minerals, and the comprehensive utilization of quartz, mica, garnet and other major associated minerals, so as to turn the resource advantages of "three stone" into economic advantages. In short, China's high aluminum mineral development and utilization base should be formed in Nanyang area, Henan Province, and its procts will occupy an important position in domestic and foreign markets

at present, the "three stones" in our province are mainly mining rich ore, high-quality ore, and selling beneficiation concentrate after beneficiation treatment, and the research on the proction of special refractory procts with them needs to be strengthened. It should be developed in the direction of high-grade series of andalusite brick, sillimanite brick and amorphous refractory. Increase the proportion of high-quality and high-grade refractory procts with high added value, and change the situation of only selling raw materials and low-grade procts

in order to meet the development requirements of domestic metallurgy and other high-temperature instries, and increase its share in the international market, a batch of high-quality synthetic refractory materials and high-efficiency procts with high technology content, good market prospect and instrialization should be developed as soon as possible, such as sintering materials, electric melting materials, rection nitriding materials, high-quality amorphous refractory materials, etc

to build a number of high-quality and efficient refractory raw material bases which are representative in technology and radiation in economy, and can drive related instries and have a certain scale. Such as thousand ton slide plate, thousand ton continuous casting nozzle, thousand ton vent plug, thousand ton high quality kiln furniture, thousand ton new unshaped refractory, thousand ton new century coke oven silica brick proction base

By adjusting the proct structure, the proportion of ordinary refractory procts decreased to less than 40%, the proportion of amorphous refractory materials increased to more than 35%, and the output value of high-quality and efficient refractory materials accounted for more than 70%. We will cultivate a number of leading enterprises with advanced management, strong technological innovation ability and annual output value of 100-500 million yuan

Second, strengthen the comprehensive utilization degree of Shangtianti non-metallic minerals, and strengthen the development of raw ore deep processing instry. Among them, perlite, bentonite, zeolite, tuff and other instrial reserves of large, good quality has been well-known at home and abroad. The mining area has a good economic, traffic and geographical environment. Although the mine has been developed for many years, the resources have not been reasonably utilized. Basically, the raw ore is sold, and the economic benefit is very poor. In order to get rid of this situation, we must fully and rationally develop and utilize all kinds of minerals in Shangtianti, strengthen scientific experiment and research, and expand the varieties and application fields of various deep-processing procts

The first is perlite, which is the main raw material of lightweight building materials. The rapid development of the construction instry puts forward higher requirements for building materials, which need a large number of new building materials with high strength, light weight, good heat and sound insulation performance, expanding the use area and improving the construction progress. According to the demand of construction market, the following procts should be developed: light perlite interior wall panel, light perlite exterior wall panel, light perlite wall block, perlite ceiling decorative panel, high-grade perlite roof insulation brick and tile, etc. To develop these procts, we should pay attention to solve the following technical problems

The first is to transform the existing perlite expansion furnace or introce a new type of expansion furnace. At present, the expansion ratio of the expansion furnace used is small, the - 60 mesh perlite can not be put into the furnace, the proction efficiency is low, and the pollution is serious, especially the glass shell perlite beads which meet the requirements of the construction instry can not be expanded. However, the Japanese bought a large number of Shangtianti perlite sand and proced various sizes of glass shell perlite beads, which were made into high-grade light-weight building boards of various colors

The second is to strengthen the research on comprehensive utilization of perlite powder and expand its application scope. Especially the utilization of - 60 mesh mineral powder. In addition to improving and manufacturing the new expansion furnace and expanding the size range of the slag powder, it is necessary to strengthen the experimental research on the silicon sources used as ceramic raw materials, perlite foam procts, filter aids, raw materials, abrasives, fillers and chemical procts, so as to solve the problem of resource waste and environmental pollution. p> The third is to develop the proction process of perlite plate. From preparation, mixing, molding, curing, drying to packaging and warehousing, a set of efficient, low-cost and complete proction process is formed, which completely changes the current backward proction mode of manual operation

Fourthly, it is necessary to develop a new and practical early strength curing adhesive, which is a necessary material for the proction of perlite plate. This adhesive must have the characteristics of good bonding effect, firmness, weather resistance, non-toxic and low price

In addition, new uses of perlite have been found. For example, as adsorbent: animal feces fast deodorization, activated with hydrochloric acid or sulfuric acid, used for purification of wastewater and waste; As carrier material: it is used as carrier of insecticide and herbicide, and it still has fluidity after reabsorption. It can also be used for perlite cement mortar, which has the characteristics of flame retardant and good insulation, and is 60% lighter than conventional cement mortar; If reinforced fiber is added, the anti cracking strength is high, and the perlite cement slurry is easy to use. Perlite powder is a kind of rubber and plastic filler with better quality

The main proct of Shangtianti bentonite ore is - 200 mesh calcium base powder after fine grinding of raw ore, which has poor technological performance and low economic benefit. In order to completely change the backward situation of relying mainly on the proction of - 200 mesh calcium based powder, we must first solve the problems of bentonite purification technology and equipment. Only the purified raw materials can be processed into high value-added procts. Aiming at the purification procts with different content of montmorillonite, organic bentonite, lithium-based bentonite, high-efficiency activated clay series procts and high-quality foundry clay were developed

At present, the zeolite ore in Shangtianti is mainly used as cement raw material, so its application in agriculture, environmental protection and other fields should be strengthened

the tuff of Shangtianti has high iron content, so it can be used as glass material instead of soda ash after removing iron

The Shangtianti non-metallic deposit is a variety of non-metallic deposits, which is a unique advantage. The mining area has a good economic, traffic and geographical environment, and has a certain foundation after years of development. It is necessary to strengthen the investment in Shangtianti mine, organize scientific and technological research, reform and update old equipment, focus on the proction of market-oriented deep processing procts, and graally build Shangtianti mine into a base for the comprehensive development and utilization of non-metallic mines in China

Graphite is one of the dominant non-metallic minerals in Henan Province, mainly distributed in the mountainous areas of Western and southwest Henan Province, with abundant reserves. Among them, Lingbao flake graphite ore and Xixia cryptocrystalline graphite ore are in the middle
