Ethereum wallet application address
I. the meaning of blockchain
in a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
ENS is Ethereum domain name service, a distributed, open and extensible domain name system based on Ethereum. Some hash addresses used in Ethereum ecosystem are usually very long, such as Ethereum wallet address and swarm file hash address, while ENS domain name system is designed to provide users with short and easy to read domain names. Ens does not grant any trademark or declare any ownership. The domain name application of ENS is a completely decentralized process. The domain name is not obtained through purchase. You need to deposit a certain amount of ether coin in the corresponding registration contract as a deposit for at least one year. In order to avoid garbage and meaningless operation, the process of auctioning domain names includes locking deposit and destroying penalty, trying to ensure that the domain name will be registered by the actual user. The ether money spent in the process will eventually be returned to the successful bidder and destroyed in breach of contract. It will not generate income and is completely non-profit.
first register and log in Bitz, find Ethereum under the asset, and click recharge to get the recharge address
then charge the Ethereum in your wallet directly to this address.
first of all, confinement is usually for one month. So whether at home or in the confinement center is the same, it needs to live for a month. But this time is not certain, can only be said to be at least a month's time to live. A month is a minimum time, even if the maternal recovery is fast, but also to live enough for a month. But if the maternal recovery is relatively slow, then it is not only to live for a month, it is necessary to live longer. Therefore, it is more recommended that pregnant women take delivery at home, which is more convenient and comfortable<
secondly, confinement is the key period for a newborn baby to recover. During this period, it is necessary to take good care of the baby. The time of each confinement is different, but it is generally 30 days or 42 days, so the body will recover more completely
in the end, the place to take delivery of the baby must choose a better place, a place with more complete facilities and better service. Otherwise, if the pregnant woman goes to the delivery center and no one is in charge, the delivery of the baby will be greatly reced
pay attention to diet after childbirth:
women have higher requirements for diet when they are in confinement, and many women think that there are not so many restrictions after childbirth, but as long as women are still in lactation, there are still many things to pay attention to
1. During lactation, women should not eat food with milk returning function, such as leek, malt, etc. Many women think ginseng tonic body is very effective, but ginseng will make maternal milk, in breast-feeding, it is best not to eat. In addition, more estrogen content of food is also easy to cause milk, such as pigeons, hens and so on
2. Women should not eat caffeinated food ring lactation. Caffeine can stimulate the nervous system. It is likely to enter the child's body through milk, causing damage to the child's nervous system and heart, and also causing indigestion
3. Eat less salt and monosodium glutamate, too much salt will increase the burden on the kidney. And monosodium glutamate will affect the development of children, eat too much monosodium glutamate will make children appear mental retardation, growth retardation and so on
women should not only pay attention to their diet when they are in confinement, even when they are out of confinement, as long as they are still in the lactation period, they can not do whatever they want in their diet, so as not to have adverse effects on their children.

Digital China is an auxiliary line for diverting funds, which resonates with the index at the end of the day, but it is difficult to judge whether to take advantage of the situation or build up the momentum. It still depends on the situation.
Through the method of experiment, the cutting force data of various influencing factors are measured, and the expression reflecting the relationship between various factors and cutting force is obtained by processing, which is called the empirical formula of cutting force calculation
In practice, there are two empirical formulas of cutting force: one is exponential formula, the other is unit cutting force. Exponential formula: FC = KC & # 8226; ap• f=kc• hd• bd kc=Fc/A d=Fc/(a p• f)=F c/(b d• h d)FP -- back force (n) P>

extended data:
compared with ordinary machine tools, CNC machine tools have the following characteristics: high machining accuracy and stable machining quality; high precision and stable machining quality; It can carry out multi coordinate linkage, and can process complex parts; When the machining parts are changed, generally only the NC program needs to be changed, which can save the proction preparation time
the machine tool itself has high precision and rigidity, and can choose favorable processing amount, with high proctivity (generally 3 ~ 5 times of that of ordinary machine tool); High degree of automation of machine tools can rece labor intensity; The quality of operators is required to be higher, and the technical requirements of maintenance personnel are higher
