China has a strong household registration statistics and management system. Why does it take time, effort and manpower to conduct a census...

1. Accurately understand China's population data. China has a strict household registration management system. Basically, citizens born in China have their corresponding information in the household registration management system.

2. Now that the network is so developed, the census still needs to be conducted manually. The main reason is that people are unwilling to take the initiative to register their personal information. There will be many problems in the process of registering information, so manual supervision and guidance are also needed.Only in this way can the analysis of the work data of the census be completed.

3. The national census is conducive to improving the population development strategy and policy system, and promoting the long-term balanced development of the population. China's economy is in the trugy period of transforming the development mode, optimizing the economic structure and transforming the growth engine.

4. In addition to "people's investigation", these things also need to be investigated. First of all, black accounts, fake households and newborns without household registration, etc. This information is not comprehensive enough, or the information registration is not timely enough. These require census officers to conduct in-depth census and visit each family accurately to count Get more real data.

5. The status of materials and resources provides a reliable basis for the country to formulate long-term plans and policies. Therefore, census is a kind of comprehensive investigation, which has the advantages of comprehensive, detailed and systematic scope of information.The census is a one-time special survey, because the census has a large workload, a lot of money, and a long time cycle, it is generally not suitable to be held frequently.

Which is better, fire-fighting system or human defense system

The type is different. The human defense project is an important facility to prepare for sudden enemy attacks, effectively cover up personnel and supplies, and preserve the potential of war. It is an engineering guarantee that adheres to urban combat and supports the anti-aggression war for a long time until victory. Firefighting is to prevent fire. Things to be prepared for are different. Human defense is to prevent mechanical, physical and biochemical injuries.

Different definitions Human defense planning: Urban human defense planning, in China, refers to an integral part of urban master planning. Fire planning: Urban fire planning is actually an urban fire construction plan. It is a comprehensive technical work with strong guidelines and policies.

Ventilation does not belong to the fire department, but is only used as ventilation. However, now, in order to save costs, many basements, including human defense, use ventilation and fire exhaust smoke together, and this kind of fan uses a dual-speed fan. Usually, the ventilation is low-speed, and when the fire alarm linkage starts the fan, the smoke is discharged at high speed.

Fire reporting is different from human defense reporting. The object of the report is different. The fire department is reported to the fire department, and the person's defense is reported to the human defense office. The content of the drawing is different. In addition to the main body and structure of the building, there are also the facilities of the human defense part; fire protection is the main body, structure, installation drawings of the building, etc.

System I and System II

1. Kahneman quoted the concept proposed by early psychologists Gis Stanovich and Richard West to divide human consciousness into two sets of thinking systems, namely system 1 and system 2. System 1" refers to an unconscious and fast-thinking way of thinking, which is an unconscious way of thinking.

2. Type I system and Type II system in automatic control theory are the number of poles of the open-loop transmission function of the system at the coordinate origin, that is, the type of the system. Type I system and Type II system have one and two respectively.

3. This theory may first come from Thinking Fast and Slowly. Daniel Kaneman said that the thinking operation system of our brain is divided into system one and system two. System 1 is characterized by particularly fast response, low energy consumption and sensitivity. For example, when we see a snake, we will be afraid and want to escape, which is the system at work.

4. The operation of System 1 is unconscious and fast, without much brain, no feeling, and completely in a state of autonomous control. System 2 shifts attention to brain-consuming brain activities to include complex operations. The operation of System 2 is usually associated with subjective experiences such as behavior, choice and concentration.

5. System I and System II are the "dual-process theory of the human mind" proposed by Stanovich, which was later promoted by Carniman in his book Thinking, Fast and Slow.

How to distinguish between global view and system optimization

1. In a sense, system optimization has a relationship between whole and part, but the system has three characteristics, namely integrity, order and internal structure optimization.

2. The concepts are different. Real-time optimization refers to real-time optimization, and global optimization refers to the optimization of the whole situation. The scope is different. Real-time optimization refers to partial optimization, and global optimization refers to overall optimization.

3. The distinction. The comprehensive view focuses on all the elements of a thing and related things. The systematic view focuses on the relationship between various elements of a thing; then consider whether the thing and the related things constitute a larger system. The systemic view is the sublimation (scientificization) of the comprehensive view.

4. The system is a unified whole composed of interconnected and interacting elements. The basic characteristics of the system are the optimization trend of integrity, order and internal structure. To master the method of system optimization, we should focus on the integrity of things, pay attention to the orderliness of the internal structure of the system, and pay attention to the optimization trend of the internal structure of the system.

The process of material exchange between the internal environment and the external environment

What do you want to ask is the material exchange process between the internal environment and the external environment? The biophysiological process is realized. According to the query elite tutoring network, the exchange of substances between the internal environment and the external environment is realized through the breathing, digestion, excretion and other physiological processes of organisms.

The outside worldThe exchange of substances between the environment and the internal environment requires the participation of various systems such as digestion, respiration, circulation and urination. Cells and the internal environment also influence and interact with each other.

The internal environment is the medium for the exchange of substances between cells in the human body and the external environment. The internal environment is the place where cells directly exchange substances and the environment in which cells live directly.

The difference between system and coordination

The overall balance is the premise of system promotion. Overall balance and integrated promotion are the distinctive characteristics of discipline inspection and supervision in the new era. The concept and idea of overall balance and integrated promotion, especially the integrated promotion of the ideas and measures of not daring to be corrupt, cannot be corrupt, and does not want to be corrupt, provide an important guideline for the realization of high-quality development of discipline inspection and supervision in the new era.

The relationship between the system concept and the overall balance is that the system concept can help better understand and recognize the interconnection and dependence between things, so as to better coordinate and coordinate.

The difference is as follows: the scope of overall application is wider, and the scope of application is relatively less. Coordination generally refers to preparing for something.

The management method is different: the personal account is recorded in the medical insurance system, which is owned by the insured individual, and can be carried over across years and inherited according to law. The coordination fund is recorded in the medical insurance system and unifiedly managed by the medical insurance agency. The funds are dedicated and shall not be misappropriated.
