Virtual currency address transaction
Here are some personal experiences in the exchange
(1) the coin search website has the advantages of low service charge, quick withdrawal and multiple currencies. It supports a variety of well-known virtual currency transactions and is convenient to purchase usdt. It has app and high security
(2) kucoin overseas version (coin win background) has smooth interface operation, and the speed of coin withdrawal is not bad, but most of them are junk ICO coins, many names have not been heard of, such as app
(3) China bitcoin overseas version EXX (slow coin withdrawal, kengdai) gambling platform, fixed-point blasting futures pop you up, there seems to be a problem with cash withdrawal, no app
(4) fire coin overseas version, Collude with OK, dozens of junk money a week, no bottom line, many small problems. Support C2C transactions, there are app
(5) okcoin overseas version, this does not say, OK life black, although support C2C transactions, but bottomless line shelf circle coins, flicker leeks, C2C transactions can not be withdrawn, embezzle the user's assets after the decimal point of tens of millions, careful into
(6) BTCC overseas version, support us dollar UnionPay direct charge, but the handling charge is high, it is relatively low-key in China, The experience of the transaction interface is very poor
(7) the overseas version of cloud coin has few currencies and many problems, so it's all warriors
(8) currency security is currently the largest exchange in China, with the most complete currency and many activities. It doesn't card you to withdraw and recharge money. Although there are so many junk money in ICO, it doesn't have as many problems as hot money OK platform. It can be said that it is the best exchange in China. It has app, needs to turn Q, and mobile client doesn't need to turn Q
(9) Yuanbao overseas version has Canadian financial license, legal operation, insufficient depth, small amount of currency, small transaction volume and insufficient UI beautification
(10) in the bitage, the overseas version takes a very long time to review, and it takes you a long time to pick up the coin and issue the coin. The miner's fee used to be a little higher, but now it's just a little higher. 0.5% for recharge, 1% for withdrawal, and the highest withdrawal fee in the whole universe. The garbage made by the K-line chart can't hold on to the ICO coin. At present, this platform can't stand the temptation of interests, and the card is only issued half a day, The trading volume is a little less. At present, I have abandoned this platform
(11) the overseas version of China's bitcoin has just been opened for trading, and C2C trading has a unique qash trading area. There are many small problems, so be careful to enter
It's already so hard in 2019. Will it be even harder in 2020
2019 has passed. Looking back at the major events in the field of automatic driving in this year, we still feel that automatic driving is still so near but so far away from us
has just started this year, and Waymo has heard the news of large-scale proction of L4 class autopilot cars. This has led many people to think that L4 unmanned vehicles will soon come. But wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait. Looking at these popular driverless cars, even writers can't help but hope that the era of driverless driving will soon come
However, another recent event has left me at a loss: starsky robotics, a self driving start-up, wants to sell itself because it has failed to raise new funds to maintain its operation. Before that, Wu Enda's driverless company, drive.ai, was sold to Apple at a low price e to financial difficulties. Another start-up driverless company, oryxvision, directly announced its shutdown. Even cruise, its driverless company, announced that it would postpone the deployment of robotaxi. The author also thinks that the current situation of driverless may not be so optimistic, Large scale commercialization still has a long way to golet's review these landmark events in the field of automatic driving in 2019
general Cruise postponed the autopilot taxi program. At the beginning of
2018, when GM released the relevant information on the fourth generation of CruiseAV autopilot, it had indicated that it would put the automatic driving vehicle safely into commercial application in 2019. However, after nearly a year and a half of preparation, in July 2019, cruise CEO Dan Ammann suddenly announced that cruise would postpone the auto driving business plan originally scheled for formal implementation in 2019, and said cruise was discussing with regulators how to measure when its technology "only has a positive impact on road safety"

Waymo said the new plant will focus on large-scale proction of L4 class automatic driving vehicle to expand its automatic driving business. Waymo said in a statement: "with the commercialization of our business, the number of autopilot cars has begun to increase. We need an expandable and powerful autopilot assembly plan. We're preparing for that now, and it's going to start in Michigan. " However, Waymo is not alone in running the project, but by co operating with Magna, the autopilot system is installed on the cars proced by the partners. Waymo executives said the company plans to do so in mid-2019 and put the project into operation in 2024
local time on April 23rd, Waymo said it had reached an agreement with the US axle manufacturing company, which was relocated at an old factory in Detroit to rebuild the autopilot car. It is reported that the factory will become the second factory in Michigan to manufacture L4 automatic driving vehicle, and Navya, a self driving feeder manufacturer, has opened an assembly plant in Saline, Western Detroit, Michigan. p> On September 26, the network announced that the trial operation service of the autonomous taxi team robotaxi was officially opened. Since then, ordinary Changsha citizens can log on to Apollo's official website to apply for being a seed user, and have the opportunity to have a trial ride
it is reported that the self driving taxi used in the trial operation of the network is the "red flag EV" jointly developed by FAW Hongqi and FAW Hongqi, with the first batch of 45 vehicles. Based on Apollo's self driving technology, these vehicles have been upgraded and optimized in all aspects, such as the software and hardware of automatic driving, the mass proction capacity of front loading of proction line, the human-computer interaction in the car, the security rendancy guarantee and the cloud fleet management. Moreover, red flag EV is also equipped with Apollo customized OBU, which can realize L4 level vehicle road cooperative sensing driving with intelligent network connected roadside devices, and reflect the current information of pedestrians and cars on the road, as well as the blind area that can't be seen from the driver's perspective, on the vehicle screen, and even give advance notice of traffic light changes and waiting time, Realize the close combination of intelligent car and intelligent road. This move marks that domestic automatic driving technology has really started to enter the market from internal R & D and carry out large-scale landing
subsequently, network Apollo further expanded the scope of robotaxi manned test, and officially opened the automatic driving manned test in Cangzhou in early November. On December 30, the joint working group of Beijing automatic driving test management issued the notice of the first batch of road manned test for automatic driving vehicles, and network Apollo won 40 automatic driving manned test licenses in one fell swoop, becoming the first domestic enterprise to carry out automatic driving manned test in Beijing. So far, the number of manned test licenses for online Apollo autopilot has reached 120, far ahead of other autopilot players in China
with the in-depth promotion of network Apollo automatic driving manned test, its layout in the field of automatic driving is constantly improving. On December 18, Apollo held the first ecological conference in Changsha. In addition to the continuous upgrading of the open platform for automatic driving, Apollo also launched two new open platforms, namely, vehicle road collaboration and intelligent vehicle alliance. So far, Apollo has formed a three platform, triple open layout
at the conference, Apollo autopilot open platform launched Apollo 5.5, the core highlight of which is the opening of "point-to-point urban autopilot" capability, which is the first time in the world that this capability is open to the outside world. In addition, Apollo also released new procts and solutions such as autonomous driving cloud, Apollo vehicle road collaborative open platform, intelligent vehicle alliance open platform, small car 2020, vehicle planning level network Swan chip, and released Apollo's report card in 2019, with 150 automatic driving road test license plates, 1237 intelligent driving patents, test mileage of more than 3 million km Road tests were carried out in 23 cities, 36000 developers worldwide, 177 ecological partners, and 560000 lines of code were opened up, comprehensively leading China's autonomous driving progress in technology, ecology and other fields
Guangzhou released the automatic driving vehicle sampling inspection method
following the announcement of the release of automatic driving road test in many places in China in 2018, in terms of automatic driving test in 2019, the favorable policy will be released again
on December 23, Guangzhou issued the measures for the management of "three tongs" test vehicles of Guangzhou Intemet vehicles (Trial) (hereinafter referred to as the measures), proposing that the same batch of "three tongs" (the same model, the same system, and the same architecture) test vehicles should, in principle, be divided into a group of at most five vehicles, one of which is randomly selected from each group, and the closed test is organized by the operation center
This means that in the future, the cost of road test for autonomous driving R & D enterprises will be greatly reced. Previously, the domestic issuance of automatic driving test qualification was based on test vehicles. If an enterprise wants to launch several automatic driving test vehicles, it must apply for several licenses However, while the measures rece the burden of enterprises, the requirements for testing vehicles are also higher and higher. For example, the "measures" stipulates that the same batch of "three same" test vehicles shall be jointly and severally liable. In case of the following situations, all test vehicles in the same group will be stopped testing: any test vehicle in the same group has accumulated 12 points in a scoring cycle; During the test, the fault light is on, the data is not synchronized to the cloud, the manual takeover is more than 3 times within 30 minutes, and the vehicle is running in a serpentine shape. This also shows that the automatic driving R & D enterprises must provide a more stable and more stable autopilot if they want to get the relevant policy convenience. p>in addition to issuing the "three same" test vehicle management measures, the regulation is also breaking the ice in cross regional test qualification mutual recognition and automatic driving manned vehicle test. In September 2019, the relevant leaders of the three provinces and one city in the Yangtze River Delta signed the "Yangtze River Delta regional intelligent network connected vehicle road test mutual recognition cooperation agreement" to effectively regulate the test behavior. Subsequently, in the administrative measures for road test and demonstration application of Shanghai intelligent network connected vehicle (Trial), the relevant provisions clearly pointed out that the applicants who have obtained provincial or municipal road test licenses of Jiangsu, Zhejiang and Anhui can obtain the road test qualification of Shanghai intelligent network connected vehicle according to the appropriate simple procere under the condition of meeting the corresponding test and evaluation proceres
12, in the guidance of the Guangzhou city on the intelligent network joint vehicle road test, it also clearly pointed out that for enterprises that have already carried out automatic driving vehicle road tests and reached a certain level of technology in other cities in the country, the test proceres in Guangzhou can be simplified. p>
in the same month, in the detailed rules for the implementation of road test management of automatic driving vehicles in Beijing (for Trial Implementation), three stages of manned and loaded standards were defined for the first time: in the first stage, the safety test with the manned test benchmark of more than 100000 km for internal staff was carried out; In the second stage, we will carry out a safety test with a manned test benchmark of more than 500000 km for social personnel; In the third stage, we will carry out a safety test with a manned test benchmark of more than 1 million km for social personnel, and apply for at least 50 test vehicles. It can be seen that although the policy level has been relaxed, it is not easy to get a license for automatic driving manned test in Beijing

In today's society, e to the high proportion of coal volatilization, the enthusiasm of burning slime in small and medium-sized pulverized coal fired boilers has been improved. Adhering to the new instrialization path, China's rapid economic growth, especially the state's incentive policy for comprehensive utilization of slime. This will bring many difficulties to the coal system of the power plant. According to the calculation, it is necessary to speed up the elimination of backward proction skills, processes, skills and equipment. However, when the moisture content of coal slime is not well controlled, the power sector has caused difficulties in the past e to the entry of coal slime into the coal dryer / lignite dryer system. However, e to the economic benefits, e to the introction of pre crushing, evacuation, dispersion and anti sticking processes in the slime drying process, the plan of coal dryer and lignite dryer is reasonable. Slime is a proct bred in the process of coal mining, and 30% of Slime (weight ratio) can be used when burning medium coal. The application of slime in pulverized coal fired boiler should be carried out actively; Change the cage for birds & quot; According to the strategy, the power plant used slime as fuel to maintain a relatively long-term operation. After manual cutting and drying, it fell behind the coal pulverizing system with intermediate storage bin, but it also paid huge resource and environmental prices. It should be recognized that this has realized the comprehensive utilization of slime, and the utilization of slime can reach 50% (weight ratio) when burning raw coal
practice has proved that the small and medium-sized pulverized coal fired boiler can bring benefits to the enterprise with low energy consumption. The coal dryer and lignite dryer adopt the new technology of crushing and evacuating the slime first, and then thermal drying. Improve the proct awareness

The internal structure of our equipment is very particular, and the selection of special rable materials, the weight tons of coal dryer and lignite dryer are real.
in the selection process of coal dryer and lignite dryer, we need to see the size and cohesiveness of the materials, and choose different forms of board reading. Coal dryer / drying system of lignite dryer includes dryer, combustion furnace, feeder, discharge machine, st removal system, etc
Application of chemical construction coal dryer / lignite dryer: it can dry sticky materials that can not be processed by ordinary rotary dryer. It is a patented proct developed and designed for sticky filter cake materials, which is suitable for drying sticky filter cake materials such as coal slime, washed clean coal, urban sludge, coal slime, choline chloride, red mud, biological waste resie, etc. in large-scale proction
working process of coal dryer / lignite dryer: the slime containing 27-30% moisture is evenly and continuously sent into the coal dryer / lignite dryer through the feeding belt conveyor. The main body of the dryer is a slightly inclined and rotatable cylinder. The hot air generated by the hot blast stove enters the dryer through the connecting pipe, and contacts with the wet coal slime downstream. Coal drying machine / the internal depolymerization mechanism, movable grate wing plate, cleaning device and crushing and dispersing device of lignite drying machine are used to crush the wet coal slime, mix, advance and strengthen heat exchange, and finally dry the wet coal slime into a loose spherical proct with final moisture of 12% - 16% and particle size of about 5-20 mm
features of chemical construction coal dryer / lignite dryer: no material accumulation on the machine wall, high thermal conctivity, fast drying speed, uniform and sufficient drying, good quality, high efficiency and energy saving, etc. Slime dryer | slime drying equipment heat supply system, heat exchange system, ventilation and st removal system organically combine and play its best effect. Among them, the idea of high temperature fast boiling furnace, sectional drying and the collection method of high humidity waste gas st are the first in China. The system of coal dryer and lignite dryer integrates heating, drying and st collection into an organic whole to maximize the drying efficiency of the whole system
the wechat app with the characteristics of "open to use, run out" innovates the service mode of the museum instry, and is one of the convenient and efficient ways to spread museum service and culture. The application of wechat app in museums will open up new channels and paths for the spread of museum culture. Three trends are attracting the attention of the instry:
first, the cultural interpretation and media of cultural and Museum institutions with physical objects as the media are increasingly inseparable from the extension and flying role brought by digital technology. The historical experience of "a thousand years at a glance" and the cultural confidence from the heart will often be better released in the context of physical objects and mobile screen
secondly, the smart guide, smart service and smart management presented by smart museum are increasingly becoming the inevitable choice for the development of Museum in the present and future
thirdly, the cooperation between museums and high-tech enterprises, especially the enterprises of digital proction and R & D, is becoming a work norm that cannot be separated from each other.
