1. It means to give away. For example, 300 blood diamonds come with a gift bag of 300 blood diamonds, which means that you will give you 300 diamonds in addition to the 300 diamonds you spend 30 yuan on
2. I don't think so
3. Yes,
bitcoin's
computing power is very high now. You have to use a professional
mining machine to dig. Using on-line software is pure deception. Be careful
4. The transfer of the wallet is actually the transfer of the BTC in the wallet, so direct remittance is the most convenient. You can choose not to pay for the transfer. Although it is slower, it is generally acceptable. The private key is actually a string. To understand it simply, f (data, private key) = secdata, where f (x, y) can be RSA algorithm. Conversely, f (secdata, public key) = data. In other words, the data encrypted with the private key can be decrypted by the person who has the corresponding public key, and you can't solve it yourself (unless you also have a public key, Of course, you usually have) in addition to encryption, it also has the function of "non repudiation". If you use your public key to encrypt a data, only the person who owns the corresponding private key can unlock it, which is usually owned by only the person who owns the private key. Key pairs must be generated at the same time. Specifically, in bitcoin software, they are generated automatically ring installation. This private key will be used automatically in the software, but it is usually not used directly. It is thought that asymmetric algorithms such as RSA consume resources, so it is usually encrypted with a symmetric algorithm first, and then RSA encrypts the random key of that symmetric algorithm, Then the two parts are added together for transmission, so it's not necessary for you to know your private key for operability, unless it's for research. In daily backup work, the software has dealt with the backup of the key and bitcoin data link, at least in the Windows version. Users only need to back up their wallet, which is equivalent to exporting all the required information, Earlier, BTC still had a problem. After a backup, if you have experienced more than 100 remittance operations, you must back up again, otherwise you will lose BTC. I don't know if it is completely repaired now, but it's not troublesome and safe to back up more than once.
5. You have to look at this on the forum of that website, or not
6. Mu is the unit of area, cubic is the unit of volume, the two can not be converted
1 mu = 666.667 m2
Mu is the unit of land area in China's municipal system, one mu is equal to 60 square feet, and 15 mu is equal to one hectare
60 square feet is selected because of the counting method in ancient China. Nowadays, most counts are carried by ten units, while in ancient times, most counts are carried by & quot; 60 "is a unit carry
Unit conversion:
1 mu = 10 points = 60 square feet = 6000 square feet
1 m = 3 feet; 1 square meter = 9 square feet; On the other hand, 1 square foot = 1 / 9 square meter
Therefore, 1 mu = 6000 / 9 m2; 1 point = 600 / 9 square meters = 66.67 square meters
extended data:
there are three land area units stipulated in China: square kilometers (km & # 178;),
, Ha, Square meters (M & # 178;). Mu, mu (a) should be avoided. The symbol of hectare is HM & # 178;, Ha is not recommended in China
unit conversion
1 mu = 10 points
1 mu = 60 square feet = 6000 square feet
1 m = 3 feet; 1 square meter = 9 square feet; On the other hand, 1 square foot = 1 / 9 square meter
So 1 mu = 6000 / 9 m2
1 point = 600 / 9 square meters = 66.67 square meters
the formula of changing square meters into Mu is "add half and move left three". 1 square meter = 0.0015 mu, for example, convert 128 square meters into mu
the calculation method is: first use 128 plus half of 128: 128 + 64 = 192, and then move the decimal point to the left by 3 places, that is, the mu of 128 square meters is 0.192
7. If the main prosperous talent is Ziwu or kuiding's share of gold, this Anyu pond can not only urge talent, but also have many happy events, the Western unitary position is greedy wolf, the Wuqu lucky star prison position, the second position is e south, and the left auxiliary prosperous star prison position
8. 1. The relationship between power and area is converted according to the general situation in the calculation of fish pond refrigeration. The corresponding refrigeration capacity per square meter is 180W, and the heating capacity is 220W, which can be used to determine the cooling capacity and power of the air conditioner. For a small fish pond, it is a waste to choose a large number of air conditioners; For the large space of fish pond, if the number of pieces is not enough, the ideal refrigeration and heating effect can not be achieved
2, refrigeration principle
liquid vaporization refrigeration is realized by the endothermic effect of liquid vaporization and the exothermic effect of liquid condensation. The liquid vaporizes to form steam. When the liquid (refrigerant) is in a closed container, there is no other gas in the container except the liquid and the vapor generated by the liquid itself. The liquid and vapor will reach equilibrium at a certain pressure. At this time, the gas is called saturated steam, the pressure is called saturation pressure, and the temperature is called saturation temperature. In equilibrium, the liquid is no longer vaporized. At this time, if part of the steam is removed from the container, the liquid must continue to vaporize to proce part of the steam to maintain this equilibrium. When liquid vaporizes, it needs to absorb heat, which is called latent heat of vaporization.
9. It depends on what kind of school you are. If you attack high, you should burn double. If you are similar to FC, you should brush the school constantly, because no one will take you, except that you have good friends
