Digital currency microblog with the most attention

1. Yes, and it's 100% layoff
but this is in the future. The future wallet may be just a mobile phone, or a small pendant, or just your face recognition, or your iris scanning, or your DNA sequence, or the electronic identification chip implanted when you were born...
the development of the wallet will replace human beings, regardless of the instry. All the workers in the operation workshop have been replaced by robots. Why can't the money printing factory
don't be biased. Technology will bring a lot of things in the future. All mechanical and non creative instries will be replaced
even the current financial instry has begun to be replaced by artificial intelligence (the largest in the United States), service robots in banks (being promoted in China), medical robots (Japan), newspaper editors (many articles in China have been written by robots)...
too many
in a word, there are endless ways for technology to defeat what you think is solid
to say the ultimate future of a future financial instry, the future national finance is likely to be replaced by all kinds of bitcoin, lightcoin and so on. In other words, the financial system of the future world is one or more, and the original intention of blockchain design is to de govern
forget it, it is estimated that it will be blocked again
learn by yourself.

Transmission ratio = working torque ÷ nine thousand five hundred and fifty ÷ Motor power × Motor power input revolutions ÷ Service factor

transmission ratio = driving wheel speed divided by driven wheel speed = reciprocal of their graation circle diameter ratio. That is:

characteristics of gear transmission

1. High efficiency. In common mechanical transmission, gear transmission efficiency is the highest, and closed transmission efficiency is 96% ~ 99%, which has great economic significance for high-power transmission

Compared with belt and chain drive, compact structure needs less space

It works reliably and has a long service life. Gear transmission with correct and reasonable design and manufacture, good use and maintenance is very reliable, and its service life can be as long as ten or twenty years, which is incomparable with other mechanical transmission

Stable transmission ratio is the basic requirement of transmission performance. Gear transmission is widely used because of its characteristics

3. The pressure angle is the acute angle between the direction of force and the direction of motion without calculating the friction. The larger the pressure angle is, the more difficult the transmission is. The remainder of the pressure angle is called the transmission angle. The pressure angle or transmission angle of mechanism is one of the indexes to evaluate the dynamics of mechanism. The maximum pressure angle or minimum transmission angle should be limited in the design of mechanism.

4. How to calculate the area after force transfer in the process of soil force transfer
1. C2F double flange force transfer joint adopts GB / t12465-2002, and the former model of double flange force transfer joint is vssjaf
2. The double flange force transfer joint is composed of flange loose sleeve expansion joint, short pipe flange, force transfer screw and other components. The double flange force transfer joint can rece the pressure thrust (blind force) of the connected parts and compensate the installation error of the pipeline. The double flange force transfer joint can not absorb the axial displacement. Double flange force transfer joint is mainly used for loose sleeve connection of pump, valve and other accessories
3. Single flange loose sleeve force transfer joint, model vssjafg (1999 standard) or CF (2002 standard), is composed of flange loose sleeve expansion joint, short pipe flange, force transfer screw and other components. It can transfer the pressure and thrust of the connected parts (blind plate force) and compensate the installation error of the pipeline. It can not absorb the axial displacement. It is mainly used for loose connection with the pump, valve and other accessories. Features: simple and convenient installation, convenient valve installation; Features: one side flange, one side welding.

5. The transmission performance of mechanism can be measured by C. transmission angle. The transmission angle and pressure angle are the remainder of each other, that is, the transmission angle plus pressure angle is equal to 90 ° The smaller the pressure angle is (the larger the transmission angle is), the more "consistent" the force is with the direction of motion. When the pressure angle is 0, the direction of force is "coincident" with the direction of motion. For reference.

From the collective collapse of the currency circle, 220000 people burst this situation to analyze, further deepen the concern of outsiders for virtual digital currency, their market is graally recognized, more and more not optimistic{ RRRRR}

the fourth reason is that virtual digital currency has the characteristics of insecurity. To put it bluntly, this kind of virtual digital currency without physical support is just a string of data on the network. This data situation is very vulnerable to hackers. In fact, virtual digital currency has been stolen by hackers for many times. Afterwards, there is no way to investigate. For those customers who have been stolen virtual digital currency, It's all the result of bad luck

7. How to prohibit QQ security components to solve the conflict between QQ and 360
the principle is very simple, and the operation of QQ security components is prohibited
XP system, in C: &# 92; Documents and Settings\ User name & # 92; Application Data\ Tencent\ Under QQ, set the permission of safebase folder to completely reject

win7 system, in C: &# 92; Users\ User name & # 92; AppData\ Roaming\ Tencent\ Under QQ, set the permission of safebase folder to completely reject

PS: despise TX again, sample, I can kill you with any setting.
