Question 2: What do you mean by function and influence? 1. Meaning: When evaluating historical events, remember: thinking must be comprehensive and answer questions dialectically from front, back and front. 2. Impact: The impact of historical events on future generations. Remember: the influence must be dealt with under the influence of reciting the book before, and supplemented and corrected appropriately! 3. Nature: the definition of a historical event is not as good as its status and class = = Remember: when answering nature, nature can only have one supplement: Note: Actually, learning history well is very simple, and the method I summarized may be beneficial to improve your historical achievements. 1. Book knowledge, read more, not only big words, but also small words! 2. One material question every day. Listen to the teacher's analysis of the material, grasp and clarify the problem-solving ideas 4. Back five more. Practice and refine this word, and then discuss it in the article as I do when answering questions.
Question 3: The purpose and significance of the paper. In the opening report, the meaning and purpose of the topic are taken as the first content, that is, whether the topic you are studying has research value or discussion value. The purpose of writing the opening report is actually to let the tutor judge whether our topic has research value, whether this research method is possible, and whether this argument logic has obvious defects.
When writing meaning, decide the form according to your topic.
It can be divided into practical significance and theoretical significance.
You can also write the purpose and meaning together without subdivision to highlight the novelty and importance of your own point of view.
Suggestions can be described from these two points, but according to their own topics, do not copy mechanically:
1. (Your topic) has not been studied by predecessors, which means that a novel and meaningful topic in the research field has been ignored by predecessors.
2. Previous studies have been made or elaborated, but the argument is not comprehensive enough. You should enrich it or refute the previous view.
In short, the meaning and purpose must be clearly stated and there must be some new ideas.
Secondly, pay attention to the theory you use. What theory do you use to prove your point?
Also make it clear, otherwise it will be difficult to be convincing.
There should also be a detailed literature review and evaluation basis of domestic and foreign research level.
Only in this way can you set off the meaning of your topic.
Question 4: What is the difference between meaning and importance and necessity? Meaning includes importance and necessity. But meaning also includes inspiration.
Question 5: What is the significance and purpose of the simulation experiment? System simulation is a new discipline gradually formed with the development of computer technology since the late 1940s. Simulation is the process of establishing the model of the actual system, and using the seen model to carry out experimental research on the actual system [2]. At first, the simulation technology was mainly used in a few fields, such as aviation, aerospace and atomic reactors, which were expensive, long-term, dangerous and difficult to achieve actual system testing. Later, it gradually developed into some major industrial sectors, such as electric power, petroleum, chemical industry, metallurgy, machinery, etc., and further expanded into some non-engineering system fields, such as social system, economic system, transportation system, ecological system, etc. It can be said that modern system simulation technology and integrated simulation system have become indispensable means of analysis, research, design, evaluation, decision-making and training for any complex system, especially for high-tech industries. Its application scope is constantly expanding, and its application benefits are becoming more and more obvious.
1. system simulation and its classification
System simulation is a comprehensive experimental subject based on control theory, similarity theory, information processing technology and computer basic theory. With special physical effect equipment such as computers as tools, the real or hypothetical system is tested with system model, and the experimental results are analyzed and studied with the help of experts' empirical knowledge, statistical data and information materials, and then decisions are made. Broadly speaking, the method of system simulation is suitable for any field, whether it is engineering system (machinery, chemical industry, electric power, electronics, etc.). ) or non-engineering systems (transportation, management, economy, politics, etc.). ).
According to different models, system simulation can be divided into physical simulation, mathematical simulation and physical-mathematical simulation (semi-physical simulation); According to the type of computer, it can be divided into analog simulation, digital simulation and hybrid simulation; According to the characteristics of the system; It can be divided into continuous system simulation, discrete time system (sampling system) simulation and discrete event system simulation. According to the relationship between analog clock and actual clock, it can be divided into real-time simulation, under-real-time simulation and ultra-real-time simulation.
2. General steps of system simulation
For each successful simulation research project, its application includes specific steps, as shown in Figure 9-2. No matter how different the types of simulation projects and research purposes are, the basic process of simulation remains unchanged, and the following nine steps should be carried out:
Problem definition
target setting
Describe the system and list all assumptions.
List all possible options.
Collect data and information
Establish a computer model
Checksum and confirmation model
operation mode
Analysis output
The following briefly defines and explains the nine steps. It is not to lead to a detailed discussion, but to play a role in attracting jade. Note that simulation research cannot simply follow the nine-step sequence, and some projects may return to the previous steps after obtaining the internal details of the system. At the same time, verification and confirmation need to run through every step of simulation engineering.
Definition of (1) problem
It is impossible for a model to present all aspects of the simulated real system, sometimes because it is too expensive. In addition, if a model shows all the details of a real system, it is often a very poor model, because it will be too complicated to understand. Therefore, it is wise to define the problem first, then set the goal, and then establish a model that can completely solve the problem. In the problem definition stage, we should pay attention to assumptions and don't make wrong assumptions. For example, it is better to assume that the waiting time of forklift trucks is long than that there are not enough receiving docks. As a simulation program, the more general the statement defining the problem, the better, and consider the possible causes of the problem in detail.
(2) Set goals and define system efficiency measures.
It is useless to simulate research without goals. The goal is to guide all the steps of the simulation project. The definition of a system is also based on the system objectives. The goal determines what assumptions should be made and what information and data should be collected; The establishment and confirmation of the model consider whether the research goal can be achieved. Goals need to be clear, definite and realistic. The goal is usually described as something like "Can you make more profits by adding more machines or extending working hours?" Wait a minute. When defining a goal, it is necessary to specify a performance measure to determine whether the goal is achieved. Hourly output rate, worker utilization rate, average queuing time and maximum queuing length are the most common system performance indicators.
Finally, the preconditions of the simulation results are listed. For example, the existing equipment must be used to achieve the goal, or the maximum investment should be within the limit, or the lead time of product ordering cannot be extended.
(3) Describe the system and list the assumptions.
In short, the simulation model ... >>
Question 6: What is the meaning of learning? 1. Learning is a necessary means for individual survival. Animals and people are inseparable from learning. Learning is a necessary condition for animals and people to keep balance with the environment, maintain their survival and development, and also a means to adapt to the environment. In order to survive and continue the population in the acquired environment, animals must first rely on the innate population instinct behavior, but this innate instinct can only adapt to the relatively fixed or small and slow external environment. In order to survive, animals and people must also gain individual experience through learning. This acquired behavioral experience can adapt to relatively rapid changes, and its significance is obviously much more important than innate instinct. For example, a lamb keeps learning from its mother, knowing where to find abundant food and how to avoid being chased by wolves. If lambs don't study, they can't adapt to the changing external environment and survive. However, the role and importance of learning in individual life are very different among various animals. The higher an animal is, the more complicated its lifestyle is, the less the role of instinctive behavior is, and the greater the importance of learning is. In lower animals, there are few behaviors and the speed of acquisition is very slow, so learning can be said to have little impact on their lives. For example, after the birth of protozoa, most of the actions in their lives have already appeared, and most of the reactions needed the day after tomorrow have already been met. Their learning ability is very low, and the time to keep experience is very short, so the result of learning has little influence on their lives. Man is the tallest animal, with an extremely complicated lifestyle and the most unstable instinctive behavior. Most human behaviors are acquired, and the ability to learn and the role of learning in human individual life are bound to be the greatest. Compared with newborn animals, the independence and innate adaptability of human infants are relatively low. It can be said that babies can't survive without the support of their parents. However, human beings have incomparable learning ability, and can adapt to the environment quickly and widely through learning. For example, growing grain, obtaining food, and relying on learning; Defeating natural enemies such as poisonous snakes and beasts, and dealing with the terrible plague will not be completely annihilated, but also depends on learning. Generally speaking, compared with other animals in nature, such as lions, tigers and even sparrows, people are at a disadvantage in many ways. People can become the spirit of all things through learning. There is a famous saying abroad, which is called "no learning, no skill". 1972, the Commission for International Education Development of UNESCO published a famous research report "Learn to survive", which directly linked learning with survival, showing the importance of learning to human survival. Second, learning can promote people's maturity. With the growth of age, people's physiology and psychology will gradually mature. But maturity is not a purely natural process completely divorced from the influence of environment and learning. The influence of learning on maturity is first supported by animal psychology research. In recent twenty or thirty years, many psychologists have found that the environmental richness of animals, especially newborn animals, can affect the development and maturity of animal senses, as well as the weight, structure and chemical composition of the brain, thus affecting the development of wisdom. D krech (1966) divided the young rats into three groups: the first group was given abundant * * *, which made its reaction more and more complicated; Let the second group live a normal life in the cage; The third group is completely isolated from the environment. After 80 days, three groups of young rats were dissected and compared. The results show that the first group is the best and the third group is the worst in terms of the weight and density of cerebral cortex. The three groups also showed significant differences in acetylcholinesterase, which is closely related to nerve impulse transmission. The first group is the richest, the second group is the second, and the third group is the least. Rosencssveig (M.R. Rosenzweig, 1972) also found that the weight and thickness of cerebral cortex, the number of glial cells and the number of synapses increased within 4- 10 weeks. Compared with another group of young mice with monotonous and harsh environment and lack of learning and training, the famous Swiss child psychologist. He also said: "As children grow older, the importance of natural and social environmental influences will increase." Experimental study on white's training of neonatal hand-eye coordination & gt
Question 7: The difference between three words: function, function and meaning: the thought and truth contained in things.
Function: the influence on the life of things
Function: the beneficial expression of something or method
As far as primary school moral education is concerned, the first thing is to understand the concept of primary school moral education and the truth contained in it, which seems to point out the direction. Secondly, the role of moral education in primary schools is what kind of influence it will have under the guiding ideology, how to implement it and the best function of moral education in primary schools. After the guiding ideology and implementation, after a period of verification, we will initially understand its effectiveness.
