What are the three levels of the complete theoretical system of athletic training and what is the focus of each level of research

The establishment of the three-level theoretical system of athletic training

When people describe the theoretical system of athletic training, it can be framed differently from the horizontal and vertical dimensions. Horizontally, the theoretical system of athletic training science mainly includes five aspects such as the principle of athletic training, the content of athletic training, the method of athletic training, the arrangement of athletic training, and the load of athletic training. Vertically, it can be interpreted as containing three levels: general training, group training and specialized training. The theory of athletic training that applies to all sports is called "general training"; the theory of athletic training that applies to some sports is called "group training"; and the theory of athletic training that applies to one sport is called "specialized training". "Specialized training science". The key to building such a three-level theory system lies in the proposal and establishment of item group training science.

In 1984, Tian Maijiu put forward the idea of establishing "classification training", and in 1987, he published a paper titled "the conception and naming of the item group training theory" in academic journals, and in 1990, he published a paper titled "the establishment and application of the item group training theory" in the Beijing Asian Science Conference, and in 1998, he published "the item group training theory" in academic journals. In 1998, he published the monograph "Item Group Training Theory".

In 2000, the publication of "sports training" national sports colleges and universities in the general textbook, the "group training theory" as an important chapter, which shows that the group training theory has been recognized by the training community, to reach the **** knowledge. The first section of this chapter for the group training theory of the general theory, including the establishment of the group training theory and its scientific significance, the division of competitive sports programs, classification and the composition of the group system and the application of the group training theory of the three aspects of the content; the second section of the athletes in accordance with the dominant factors of athletic ability of the aggregation of eight different groups of the respective athletic characteristics and training methods.

The theory of item group training has been introduced for more than ten years, and has been generally emphasized by the sports world, and has been continuously developed and improved. The main theoretical advances include: the division of the group according to the composite dominant athletic ability, multi-criteria and multi-dimensional group combinations, the characteristics of the group divided into training cycles, and the concept of the group of a wide range of applications

What are the levels of macromolecular structure? What are the contents of the study of each level

(1) The structure of macromolecules is characterized by the following four main aspects:

(1) long chain macromolecular structure;

(2) macromolecular chain with flexibility;

(3) macromolecular structure with polydispersity and inhomogeneity;

(4) with the diversity of aggregated state structure and complexity.

(2) The structure of macromolecules can be divided into chain structure and aggregation structure, while the chain structure is divided into proximal and distal structure, aggregation structure is divided into tertiary and higher structure; proximal structure is mainly related to the chemical composition of the molecular chain, structure and configuration; distal structure includes the size of the molecular chain and the geometric shape of the space; tertiary structure is the formation of aggregation state structure, which is formed by the mutual arrangement of the molecular chain of the polymer of the same kind. The tertiary structure is formed by the same type of polymer molecular chains stacked on top of each other to form the aggregation structure, including crystalline structure, amorphous structure, liquid crystal structure, orientation structure, etc.; and the higher secondary structure is formed by the polymer molecular chains of different types of different types of polymer molecules stacked on top of each other to form the aggregation state structure, including the **** hybrid structure and the structure of the organism.

(3) polymer structure level is not independent of each other, the lower structure level will affect the formation of higher structure level. For example, the proximal structure affects the conformation and chain flexibility of the molecular chains (distal structure); the stereo configuration and conformation of the molecular chains in turn affect the geometrical arrangement between the molecular chains (aggregated state structure). On the other hand, each structural level has an impact on the effectiveness of the polymer, with the proximal structure determining the basic properties of the polymer and the aggregated state structure directly affecting the effectiveness of the polymer in use.

What is studied at each level of polymer structure?

Proximal structure of polymer chains

Intramolecular and intermolecular interactions in polymers

Distal structure of polymer chains

Intramolecular rotation and flexibility of polymer chains, conformational statistics of polymer chains, conformation of chains in the polymer lattice, worms, rigid chain structure

Polymer condensed structures

Polymers Amorphous and Crystalline, Polymer Orientation, Polymer Liquid Crystals, Polymer Alloys

What is Feng Shui and is there a complete theory?

Feng Shui, this is the art of the phase of the ground, that is, the method of the field school geography, also known as the ground phase, the ancient name of geomancy, according to legend, the founder of the Feng Shui is nine days of the Xuan Nü, the more perfect Feng Shui originated in the Warring States period. The core idea of feng shui is the harmony between man and nature, the early feng shui is mainly concerned with the palaces, houses, villages, cemeteries, the location of the site, the seat of the direction, the construction and other methods and principles, the original meaning is to choose the right place of a study.

Chinese Feng Shui, now known as the study of the living environment, originated in the primitive period, the prototype in the Yao and Shun period, matured in the Han and Tang dynasties, and flourished in the Ming and Qing dynasties. Feng Shui is a valuable experience accumulated by human beings in the long-term practice of living. Facing the sun, avoiding wind and rain, preventing fire, being close to water sources, and facilitating traveling have become the most basic theories of living. Thousands of years or even tens of thousands of years, people continue to summarize the advantages and disadvantages of the living environment to the Han and Tang dynasties formed a very mature and systematic theory of Feng Shui in China. Peng Zu's disciple, Qing Yi, said: "The internal qi sprouts, the external qi takes shape, the internal and external multiply, and feng shui comes into being. Jin Guo Pu "funeral scripture" explains feng shui: "gas multiplied by the wind will be dispersed, the boundary of the water is stopped, the ancients gathered so that not scattered, traveling so that there is a stop, so it is called feng shui". In the Han Dynasty, King Huainan wrote "Huainanzi", which discusses: "Heaven and earth execute the way. To the monthly order of yin and yang changes, there is a time when the phase of the impulse, there is the time of the conjunction, the former is fierce, the latter is auspicious. The meaning of geomancy is actually the way of heaven and earth. Xu Shen "Shuowen" explanation: Kan, the way of heaven; mikoshi, the way of the earth.

Feng Shui: Taiji born two meters (yin and yang, positive and negative), two meters born four phases (five elements), four phases born gossip, gossip twenty-four mountains.　

Feng Shui is divided into: dragon, points, sand, water, water, intention, shape, day (celestial layout) all the higher Feng Shui masters, are to do according to these principles, but to combine the human destiny, the nature of the calculation; because of the former people a fortune famous saying is: a life, two luck, three Feng Shui, four accumulation of virtue five reading; Zen master Pan Guo Jing said: the universe any substance is changing, all through the four stages of becoming, living, bad, empty. Ancient Chinese feng shui known as geomancy, also called geography so called geomancy feng shui geography. Can be interpreted as: Can (observation of the sky), public opinion (survey of the ground), wind (air space), water (hydrology and water quality), ground (topography and geology) reason (the theory of the study and analysis)

- - from the "Into the Taoist"; jies98.unibbs. Feng Shui culture is unique to China's traditional culture. One of the Feng Shui phenomenon is a natural phenomenon that does exist, so what is Feng Shui? Feng Shui Feng Shui, is the formation of wind phenomenon of water! What is the "water" in the I Ching? I learned in the "water, wood, fire, earth and gold" five elements, this water is the five elements of water, is water, not the fresh water we drink. What are the five elements of water? It is what we now call field energy. Field energy is a kind of what substance? It is the virtual substance air body. Simply put, feng shui material is the virtual air body. What is the virtual air body? Virtual matter is the air in addition to gas molecules in the space of the material, that is, the singularity of the material. We know that wind is the result of air flow. What is air made of? According to Western science, it is composed of gas molecules, according to Yijing, it is composed of "qi", and according to Taoism, it is composed of virtual matter and gas molecules. The virtual material is the "gas" material, that is, the "feng shui" material, that is, the material that forms the meridian and acupoint system. There is no gas molecules in space, but there is still wind, the cosmic wind, such as solar wind, geomagnetic wind, the essence of the energy flow generated by the planet, in the I Ching is called "line of Qi, five elements". Therefore, Yijing is correct. Wind is the result of the flow of air, not the result of the flow of air molecules, the flow of air molecules is only the phenomenon of wind, not the essence of wind. We breathe air for two purposes, that is, to use oxygen and air body: oxygen provides oxidizing energy (five elements of fire), and air body provides meridian acupoint substances - yuan qi (that is, air body). We know that too pure oxygen cannot be used for breathing, it will burn people. So what happens to too pure air body? It will cause a person to go into hibernation and fake death. Air is very important to life, because the air body can replenish the body's meridian points in the qi material, that is, yuan qi material. Yijing reveals that meridian acupoint substance (yuan qi) is the key substance that determines the quality of life, and feng shui determines the fate of living things. What is fate? It is the study of the laws of movement and action of the qi of yin and yang (now called energy, force and information). Feng Shui is an important discipline of Yijing, which is the study of the distribution of feng shui, the effectiveness of yin and yang and the five elements, and the influence of the role of life. Yijing says: "one life, one luck, three feng shui, four virtues, five names, six reading", that is, a person's life fate is determined by these six factors. Life and luck by the birth of the eight characters to decide, once born can not be changed, by reading the knowledge of the eight characters to understand; feng shui is the air in the air and energy air flow of energy air flow, life has a decisive impact; virtue is merit, is to build a career and good deeds, is an individual's contribution to society; name is the name of the community is the affirmation of the individual's behavior and contribution to the community; reading a general reference to the individual's various efforts. It can be seen that other efforts can also change the influence of bad fate, we do not need to be obsessed with feng shui, and the land resource constraints do not allow us to utilize feng shui (yangzhai feng shui techniques can be used). The effect of Feng Shui on life, Taoism has provided the method of "Tao body health care technology" and "special vacuum technology".

What are the three levels of communication studies?

I don't know what you mean by the three levels of communication research

If it is the research object of communication, it is the five media research, content analysis, control research, audience research and effect analysis.

If the three levels of communication effects are:

1. Cognitive level: the role of the domain of the people's memory system, caused by the people's knowledge, knowledge structure changes belong to the cognitive level of the effect.

2, attitude level: the role of people's concepts, value system and cause people's emotions and feelings of change, belong to the psychological and attitudinal level of the effect.

3, action level: these changes are manifested through people's behavior is the effect of action level.

If we talk about the three stages of communication research, it is: strong effect theory - limited effect theory - moderate effect theory

What is the focus of Math III?

In the case of Math III, the required advanced mathematics topics generally include:

Functions, limits, and continuity

Univariate function differentials

Univariate function integrals

Multivariate function integrals

Infinitesimal numbers

Ordinary differential equations and difference equations

So, as can be seen, the advanced mathematics is generalized calculus, with a few more grades and ordinary differentials.

Finally, don't think that 85-90 is enough for math

What is the level of automation research

Automation is divided into many levels

The current broadly divided into control science and intelligent technology

Undergraduate automation is divided into strong and weak power, strong power is mainly for the factory installations, as well as the power supply (in the past, called industrial automation), the weak power is mainly for the micro-controllers, such as the design of the hardware

For example, Tsinghua University automation covers a very wide range, including motion control, electrical and mechanical control, and the design and development of a new automation system. p> Shanghai Automation is also very good, the development of faster

Tianjin University automation to detection technology as the no1

Hefei University of Technology, mentioned above, is also the detection technology and mine automation as a strong point

Donghua University is the textile automation of the authority How many levels of pre-life material evolution and the characteristics of the various levels

Chemical origin of the origin of life into four phases (Miller's), and the origin of life is divided into four phases (Miller's). origin into four stages (Miller's experiment). The first stage, the generation of small organic molecules from small inorganic molecules, i.e., the chemical evolution of the origin of life was carried out under primitive earth conditions, a process that has been described in the textbook and will not be repeated here. What needs to be emphasized is Miller's simulation experiment. In this experiment, a flask containing an aqueous solution represents the primitive ocean, and its upper spherical space contains a "reducing atmosphere" of hydrogen, ammonia, methane, and water vapor. Miller first heated the flask, so that the water vapor in the tube back to the circle, then he two electrodes through the discharge of electric sparks, simulating the original sky lightning, in order to stimulate the different gases in the sealed device to chemical reactions, and the lower part of the spherical space connected to the condensation tube so that the products of the reaction and the water vapor cooled to form a liquid, and then flowed back to the flask at the bottom of the simulation of the process of rainfall. After a week of continuous experimentation and circling back. Miller analyzed its chemical composition and found that it contained a variety of new organic compounds including five amino acids and different organic acids, as well as the formation of cyanohydric acid, which can be synthesized into adenine, the basic unit of nucleotides. Miller's experiments attempted to confirm to people that the first step in the origin of life, the formation of organic small-molecule substances from inorganic small-molecule substances, was entirely possible under the conditions of the primitive earth. The second stage, the generation of biological macromolecular substances from organic small molecular substances. This process occurred in the primitive ocean, that is, amino acids, nucleotides and other organic small molecule substances, after a long period of accumulation, interaction, under appropriate conditions (such as the adsorption of clay), through the condensation effect or polymerization to form the original protein molecules and nucleic acid molecules. The third stage, from biological macromolecular substances to form a multimolecular system. How is this process formed? The former Soviet scholar Obalin put forward the hypothesis of agglomerates, he showed through experiments that proteins, polypeptides, nucleic acids and polysaccharides, etc. are placed in a suitable solution, they can automatically condense and aggregate into dispersed globular droplets, these droplets are agglomerates. O'Baring et al. believe that agglomerates can exhibit life phenomena such as synthesis, decomposition, growth, and reproduction. For example, agglomerates have membrane-like boundaries, and their internal chemical characteristics are significantly differentiated from the external solution environment. Agglomerates can draw in certain molecules as reactants from the external solution, and can also undergo specific biochemical reactions catalyzed by enzymes, and the products of the reactions can also be released from the agglomerates. In addition, some scholars have proposed some other hypotheses such as microspheres and lipospheres to explain the process of organic polymeric substances to form multimolecular systems. The fourth stage, Figure 7 Schematic diagram of the simple metabolism of agglomerates The fourth stage, the evolution of organic polymeric systems into primitive life. This stage was formed in the primitive ocean and is the most complex and decisive stage in the process of the origin of life. Currently, one cannot verify this process in the laboratory.
