1. 1. What is blockchain
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system [1]
2. What is a concept
concept has two basic characteristics: Connotation and extension. The connotation of the concept refers to the meaning of the concept, that is, the unique attribute of the object reflected by the concept. For example: "goods are labor procts for exchange.". Among them, "labor procts for exchange" is the connotation of the concept of "commodity". The extension of the concept refers to the scope of the object reflected by the concept. That is, things or objects with attributes reflected by concepts. For example, "forest includes shelter forest, timber forest, economic forest, firewood forest and special purpose forest", which is to explain the concept of "forest" from the perspective of extension. There is an inverse relationship between connotation and denotation of a concept, that is, the more connotation a concept has, the smaller denotation it has; vice versa. A more understandable explanation: the connotation of the concept refers to the meaning of the concept. There are necessary conditions, that is, objective things (objective objects), among which there is only one necessary condition and N sufficient conditions. The more conditions, the smaller the extension of the concept. Conditions are functional. For example: the cup needs space to carry. And it is used to hold water, wine and other liquids. Moreover, it is a kind of utensils (the defined items cannot be directly or indirectly included in the definition items), so the meaning of the concept of cup is: utensils used to hold water, wine and other liquids. And if we know the sufficient conditions, we can roughly dece the things or objects. Because it must be connected with the objective things. The functions of concept include judgment, description, attribute, category, definition (conceptual clarity), etc
the description of concept in China is: concept is avant-garde, novel, trendy, with future trend, background and picture. The concept has the strict fixed content, also has the certain fuzziness. Concept is not real, but imaginary. We should use concept to think and use concept to show its authenticity. The pattern of consciousness is endless. The more thorough the images are, the better it will be for us to enter a fine and infinite field. Otherwise, one thing will always be reced to another
from the perspective of form: ideas are more advanced, concepts appear in the form of words, and ideas usually appear in the form of a complete sentence. But in the same form; They are all based on Chinese and symbols. Therefore, it can be understood that the concept is a brilliant idea that condenses more information. Therefore, the concept is imaginative and pictorial, while the scientific concept is systematic. Concepts must also be comprehensible, so they are universal and objective.

3. Fill the 70 ml cup with 100 ml water, then there is 30 ml water left in the 100 ml cup. Pour the water out of the 70 ml cup, then pour the remaining 30 ml water into the 70 ml cup, and then fill the 100 ml cup, so that 130 ml water can be weighed out.
4. Pour some ice water into the inner cup, and then soak the outer cup in hot water. Pull it out immediately, and you can separate the two cups. This is because the heat expands and the cold shrinks, the inner cup contracts, and the outer cup expands. This tiny change can destroy the adhesion formed by the thin water film between the two cups, and the cups can be separated. It should be noted that the action must be fast, otherwise the cup will stick more firmly

6. Put ice into the small cup, soak the large cup in hot water, and use the principle of heat expansion and cold contraction to do it.
7. 50-30 + 50,
= 20 + 50,
= 70 (g)
A: you can measure 70 grams of water with these two cups
= 20 + 50,
= 70 (g)
A: you can measure 70 grams of water with these two cups

9. It should be said that: Xiao Ming wants to measure the quality of water in the cup, he first measures the total weight of the cup, m, and then pour out the water, also called the weight of the cup, m, then the weight of the water is m water = M-M. Then we get the mass of the water in equal quantities.
