Zcash force distribution
The following is the distribution chart of computing power:
the computing power of bitcoin is mainly controlled by some mine owners in the world, and the computing power of retail investors is very small, almost negligible. The computing power of China's mining pool even accounts for more than 80%, and China's voice is increasing
however, many digital currencies no longer need to be mined. Some digital currencies will be directly sent to investors through ICO, and Puyin is one of the representatives, but these digital currencies generally correspond to real assets
Aries clothing = constellation badge + sheep BAABAA (sheep Baa Baa is bought in the mall, gold coins × 20)
Gemini clothing = constellation badge + double row chocolate (double row chocolate can be mined). Pure guess luck)
Leo clothing = constellation badge + love gift box (love gift box mining can get, also can buy from players)
Virgo clothing = constellation badge + snow wool (snow wool can raise sheep, also can buy from other players)
Taurus clothing = constellation badge + Taurus (Taurus can buy in the mall, gold coins) × 2)
Scorpio clothing = constellation badge + Blue Crystal (blue crystal can only be obtained by mining)
Sagittarius clothing = constellation badge + Cupid's arrow (Cupid's arrow can be purchased from other players or sent by your boyfriend / girlfriend)
Capricorn clothing = constellation badge + wool (wool can raise sheep by itself, You can also buy it from other players)
Pisces costume = constellation badge + Aquarium (aquarium can go to mine, open treasure box and buy it from other players)
Aquarius costume = constellation badge + Black T-shaped water pipe + black straight water pipe (two items can be purchased from other players through mining)
I have finished this task for Libra costume and cancer costume. So I forgot what I needed.
There is no such saying, only the saying of photocell
The principle of phototube is photoelectric effect. One is the semiconctor material type of phototube, its working principle is photodiode, also known as photodiode, is thevacuum phototube
when the pole is up, e to the external photoelectric effect (see photoelectric sensor), the photoelectron is emitted from the pole layer to the vacuum. Under the action of the electric field, the photoelectron accelerates between the electrodes and is finally received by the anode with high potential. The photocurrent can be measured in the anode circuit, and its magnitude depends on the light intensity and the sensitivity of the photocathode. According to the different shapes and settings of photocathode and anode, photocells can be generally divided into five types
(1) central cathode type: because the cathode area is very small and the luminous flux is not large, this type is only suitable for low illumination detection and measurement of photon initial velocity distribution (2) Central anode type: e to the large area of cathode, the size of incident focus spot is not limited; Because the distance from photocathode to anode is the same, the electron transit time is consistent; The disadvantage of this method is that it needs higher anode voltage because of its poor photoelectron receiving characteristics (3) semicircular cylindrical cathode: this structure is beneficial to increase the insulation performance between electrodes and rece the leakage current (4) parallel plate electrode type: this type is characterized by the fact that photoelectrons fly from the cathode to the anode in a parallel straight line, and the electrode has good consistency for light incidence. ⑤ Flat plate cathode with cylinder: it is characterized by compact structure, small volume and stable operation I hope I can help you solve your doubts
