The law of medical service support mainly starts with summarizing medical service support and medical service construction, and discusses the basic and specific laws of medical service to enhance scientific prediction and provide scientific basis for medical service construction and support decision-making.
The organizational system and corresponding system established by the organization system of military medical service department provide a theoretical basis for the organization to use medical service force, give play to the role of medical service manpower and material resources, and improve work efficiency and benefit. The principles, policies, principles and rules and regulations of military health work are based on the actual situation of the army, so that health work has rules to follow and laws to follow.
Under various conditions, the extensive application of high-tech weapons and equipment in the war has brought many new features and requirements to medical support. We should strengthen the research on medical support in special geographical conditions, non-linear combat, the law of health attrition and the characteristics of war injuries, put forward the implementation methods of organizing medical support, give full play to the role of medical theory, technology and medical equipment, and continuously improve medical support capabilities.

3. Common sense about hygiene and health
In winter, there are many people running long distances.
As we all know, long-distance running is a whole-body exercise, which consumes a lot of energy and has good exercise effect, while long-distance running in winter has more benefits. Long-distance running can clean up the waste in the body. In winter, the temperature is low, and long-distance running can * * * the body's protective response, accelerate blood circulation, accelerate the blood flow in the brain, and improve the regulation ability of the brain's body temperature center, thus supplying more nutrients to the brain and making the brain more awake.
Persisting in long-distance running in winter can improve the memory function of the brain. Long-distance running in winter can also enhance the functions of cardiovascular system and respiratory system, promote the healthy work of muscles, bone marrow, nerves and various organs, thus improving the body's disease resistance, and the most obvious effect is to prevent flu.
Long-distance running in winter can also clean harmful substances in the excretory system. According to the measurement, 16 minutes running 3 000 meters or 25 minutes running 5000 meters can reduce blood cholesterol.
This has a good preventive effect on hyperlipidemia, arteriosclerosis, coronary heart disease, cerebrovascular disease and so on. In addition, long-distance running makes people full of optimism and feel comfortable, which helps to increase appetite. Long-distance running can also strengthen digestion and promote nutrient absorption.
Persisting in long-distance running in cold weather also helps to exercise willpower. Don't wear too much clothes for long-distance running in winter. Due to the low temperature in winter, you should pay attention to the following aspects when exercising for long-distance running.
Before long-distance running, you must make full preparations. Do some gymnastics to move your knees, ankles and shoulders, or jog for a while first, and then officially run after the blood circulation of the whole body is improved and the upper limbs sweat slightly.
Don't wear too many clothes, and don't wear cotton clothes, so as not to cause fever, sweaty underwear and cold wind after running, which will cause colds and muscle joint pain. Pay attention to the weather for long-distance running in winter. It is foggy in winter. Remember not to exercise in the fog, which contains harmful substances such as acid, alkali, salt, benzene and amine.
After inhaling into the lungs, the oxygen supply in the alveoli is insufficient, causing chest tightness, which can cause bronchitis or some allergic diseases in severe cases. You can't stop immediately after a long-distance running in winter. It is very important to master the correct breathing method.
At the beginning of running, especially when running against the wind, you should breathe through your nose or breathe through your mouth, because the nasal cavity can reduce the cold air's impact on your throat; At the same time, mucus in nasal cavity can filter and purify air. When the running speed is accelerated, in order to take in more oxygen, it is necessary to use mouth-nose mixed breathing.
Roll up the tip of the tongue slightly against the upper jaw, so that air can be inhaled from the nasal cavity and between the teeth at the same time. Don't open your mouth and gasp, which is easy to cause respiratory muscle fatigue, cough, tracheitis and abdominal pain.
Breathing should be even and rhythmic, with one breath in two steps and one breath in two steps, or one breath in three steps and one breath in three steps. In addition, when running, you should use the forefoot to land, and it is best to wear rubber shoes with sponge soles to avoid heel pain.
During transportation, some sports drinks containing vitamin C should be supplemented several times in a small amount. After long-distance running in winter, don't stop immediately, but jog for a while, because at this time, the blood is concentrated in the lower limbs and suddenly stops, and the blood can't fully flow back into the heart, which will cause "gravity shock".
Attention should also be paid to keeping warm in time, ensuring sleep, and promoting fatigue recovery by means of * * * and hot bath. In short, knowing more about winter long-distance running can reduce the blindness of exercise and make the exercise effect of winter long-distance running better.

In order to prevent wrinkles, it should be placed on the upper floor of the wardrobe when collecting, and a few pieces of interlining can be placed on it to reduce moisture from entering the wardrobe.
Store silk clothes, don't use mothballs, or the clothes will turn yellow. Also be careful not to mix cotton silk clothing with real silk clothing, so as not to discolor the real silk clothing.
5. How to remove the odor of clothes? We can treat it with salt. Because salt can disinfect, sterilize and prevent cotton cloth from fading, it must be soaked in salt water before wearing new clothes.
6. How to prevent the TV and stereo at home from getting dusty? Dilute the clothes softener with ten times of water, and then dip it in a paper towel or soft cloth to gently wipe the surface. At this time, you will find that the dust does not adhere to the electrical appliances as quickly as before, which is mainly because the softener plays an anti-static role. 7. How to prevent the mat from slipping? Put a piece of plastic wrap under the mat, which increases the friction between the mat and the floor, and naturally it will not slip.

6. May I ask primary school students about health knowledge?
I) Main contents of primary school health care work 1. Teaching health care students' learning activities is mainly carried out through the classroom.
Therefore, the health care work in classroom teaching plays an important role in school health care work. Paying attention to health problems in teaching is not only related to the growth and development of students, but also directly affects the quality of teaching.
Teaching hygiene mainly refers to students' brain hygiene and eye hygiene. The potential power of the human brain is very great, but it must be used scientifically to play its role.
In particular, primary school students' brains are in a mature stage, which is easy to get excited and tired. If students' brains are kept in a state of tension for a long time in violation of the laws of brain activity, they will suffer from excessive fatigue, ranging from inattention, slow thinking and giddiness, to disorder of excitement and inhibition, headache and insomnia, listlessness, memory and attention loss, and then neurasthenia will occur, which will seriously damage students' health, make students' academic performance decline, and even make them unable to persist in their studies.
Therefore, we must prevent and overcome the phenomenon that students are overburdened in teaching. Students' eye hygiene should also be paid full attention to.
If students' eyesight is damaged, it will bring difficulties to students' learning, affect students' reading effect and memory, affect students' observation ability, and limit students' intellectual development; Far away, it will cause difficulties for students in their future work, make them unable to engage in certain professional work, limit their talents, and also be a loss to socialist construction. There are many reasons for students' poor eyesight, but one of the main reasons is that they don't pay attention to eye hygiene.
For example, the reading time lasts too long, the posture of reading and writing is incorrect, the light is insufficient, and the printed matter, desk and stool are not suitable. Therefore, schools should improve the illumination of classrooms under possible conditions, equip students of different grades with different types of desks and chairs, and at the same time educate students to pay attention to eye hygiene, not to read books for a long time, not to read books in places with insufficient light, to have a distance of 30 cm between eyes and books when reading and writing, and to do eye exercises frequently.
2. Personal Health Care Students' personal diet and personal hygiene is also an important part of school health care. Most primary school students live at home, and the key to personal hygiene lies in the family.
In addition to cooperating with parents, schools should also put forward reasonable hygiene requirements and necessary guidance to students. If you want to eat on time, wash your hands before and after meals, don't eat on the road, don't play while eating, don't be greedy, don't drink raw water, don't eat rotten fruits, wash or disinfect raw fruits, etc., especially pay attention to overcoming students' bad habits such as eating snacks.
Students should be educated to keep their bodies clean. Wash your face and brush your teeth before going to bed and after getting up every day, cut your nails often, and take a bath often if possible.
The cleanliness of the body can eliminate the parasitic conditions of bacteria and prevent diseases. 3. Environmental sanitation school is the main activity place for students. It is necessary to continuously beautify and green the campus, do a good job in the cleanliness of school building equipment, and ensure that classrooms, reading rooms, dormitories, toilets, dining rooms, sports grounds, workplaces and other equipment are clean and hygienic.
Schools should establish a sound environmental sanitation system, which should generally be cleaned once a day and cleaned once a week. 4. Reasonable work and rest system A reasonable work and rest system is a necessary condition to ensure that students study, work and rest regularly and make them grow up healthily.
The formulation of school life and rest system should be based on the teaching plan, taking into account students' study, entertainment, sleep and rest, and should also be suitable for students' age characteristics. The school life work and rest system is mainly reflected in the curriculum and work and rest schedule, which includes the arrangement of study time in various subjects, the time regulation of extracurricular activities (physical exercise, social activities, extracurricular group activities, etc.), and the arrangement of food, sleep and rest time.
Students must be guaranteed enough sleep time. Sleep is the basic physiological requirement to eliminate fatigue and protect health.
Pupils should have about ten hours of sleep time, and students should be educated to develop good sleep habits. Such as going to bed early and getting up early, washing your face and feet before going to bed, not eating before going to bed, not reading and talking in bed, etc.
Special attention should be paid to ensuring the supply of breakfast for students. Generally speaking, if students don't eat enough breakfast, it will affect their study in the third and fourth classes in the morning.
According to the survey of the health department, the calories consumed by students in sports, labor and study activities now exceed the calories they take in, which is noteworthy. Studies have shown that eating breakfast with sufficient calories is of positive significance for concentrating students' attention and improving their mental state.
Conditional schools can add breakfast after the second class. (2) How to do a good job in health care for primary school students. The headmaster, the director of education and every teacher of the school have the responsibility to do a good job in school health care.
However, in order to have a specific person in charge, large-scale schools should have full-time school doctors or health care teachers; Small-scale schools can employ doctors from nearby hospitals as school doctors, or designate a teacher to be responsible for the health care work of the whole school, assist the principal to supervise and check whether the environmental equipment of the school meets the sanitary conditions, and organize the teachers and students of the whole school to carry out patriotic health activities. To do a good job in health care for primary school students, we should pay attention to the following points.
1. Carry out health care publicity and education, often explain some basic knowledge of physical hygiene and public hygiene to students, put forward measures and requirements for disease prevention, and educate students to master some medical knowledge and treatment methods for common ailments. The publicity and education of health care should be combined with the patriotic health campaign.
Different contents of publicity can be carried out according to the epidemic situation of diseases in different seasons, such as food hygiene publicity in summer and prevention of colds in winter. Publicity methods should be varied, such as radio, slides, movies, pictures, blackboard newspapers, etc., and health exhibitions or special lectures can also be held.
Some schools use microscopes to organize students to observe bacteria in rotten food and nails, and have achieved good publicity results. 2. Establish various health care systems to cultivate students' good health habits. In addition to establishing a reasonable work and rest system and a clean and hygienic system, students should also have regular physical examinations, establish students' health cards, and treat diseases in time.
To check students' personal hygiene every day, we can carry out competitions and competitions, and issue a red flag of hygiene flow, so as to improve students' enthusiasm and initiative in health care. 3. Carry out "Youth Red Ten".
7. Health knowledge and learning methods.
According to many years' practice, the formula of senior high school mathematics learning is summarized and simplified; Generalization knowledge is difficult to change, and high school mathematics is clever to remember.
Concise and catchy, combined with textbooks is better. The first thing will be ugly, and throwing bricks will attract white jade.
The content of "* * * and Function" is intersected and complemented, and there are power-finger pair functions. The odd and even nature and the increase and decrease are the most obvious observed images.
The compound function appears, and the law of property multiplication is distinguished. To prove it in detail, we must grasp the definition. Exponential and logarithmic functions are reciprocal functions.
The base is not a positive number of 1, and 1 increases or decreases on both sides. The domain of function is easy to find.
Denominator cannot be equal to 0, even root must be non-negative, and zero and negative numbers have no logarithm; The tangent function angle is not straight, and the cotangent function angle is uneven; Real number set of other functions, intersection in many cases. Two mutually inverse functions have the same monotone property; The images are symmetrical to each other, and Y=X is the symmetrical axis; Solve a very regular and inverse solution to the domain of substitution; The domain of the inverse function, the domain of the original function.
The nature of power function is easy to remember, and the exponential reduced fraction; Function properties are exponential, odd mother odd son odd function, odd mother even son even function, even mother non-parity function; In the first quadrant of the image, the function increases or decreases to see the positive and negative. Trigonometric Function Trigonometric function is a function, and quadrant symbols are labeled.
Function image unit circle, periodic parity increase and decrease. The same angle relationship is very important, and both simplification and proof are needed.
At the vertex of the regular hexagon, the chord is cut from top to bottom; Write the number 1 in the center to connect the vertex triangles; The sum of the squares of the downward triangle, the reciprocal relationship is diagonal, and any function of the vertex is equal to the division of the last two. The induction formula is good, and after the negative is positive, it becomes large and small, and it becomes a tax angle, so it is easy to look up the table, and simplification is indispensable.
Half an integer multiple of two, the odd parity is unchanged, and the latter is regarded as an acute angle, and the sign is judged by the original function. The cosine value of the sum of two angles is converted into a single angle for easy evaluation, and the cosine product is subtracted from the sine product, and the formula of changing angles is deformed.
The sum difference product must have the same name, and the complementary angle changes its name. The calculation proves that the angle comes first, pay attention to the name of structural function, keep the basic quantity unchanged, and change from complicated to simple.
Guided by the principle of inversion, the product of ascending power and descending power and difference. Proof of conditional equality, the idea of equation shows the way.
The universal formula is unusual, and the rational formula takes the lead. Formulas are used smoothly and reversely, and deformation is used skillfully; 1 add cosine to think cosine, 1 subtract cosine to think sine, the angle of power up is halved, and it is a norm for power up and power down; The inverse function of trigonometric function, in essence, is to find the angle, first find the value of trigonometric function, and then determine the range of angle value; Using right triangle, the image is intuitive and easy to change its name, and the equation of simple triangle is transformed into the simplest solution set; Inequality is the way to solve inequality, using the properties of functions.
The opposite irrational inequality is transformed into a rational inequality. From high order to low order, step by step transformation should be equivalent.
The mutual transformation between numbers and shapes helps to solve problems. The method of proving inequality is powerful in real number property.
Find the difference and compare it with 0, and make a quotient and 1 to compete for it. Comprehensive method with good direct difficulty analysis and clear thinking.
Non-negative common basic expressions, positive difficulties are reduced to absurdity. There are also important inequalities and mathematical induction.
Graphic function to help, drawing modeling construction method. "Number Series" is the arithmetic difference of two number series, and the sum of n terms in the general formula.
Two finites seek the limit, and four operations are reversed. The problem of sequence is changeable, and the equation is reduced to the whole calculation.
It's difficult to sum the sequence of numbers, and it's easy to transform the dislocation and cancel each other, learn from each other's strong points and make up for each other's weak points, and calculate the sum formula of split terms. Inductive thinking is very good, and it is good to make a program to think about: one counts two and three associations, and guessing proves indispensable.
There is also mathematical induction, which proves that the steps are programmed: first verify and then assume, add 1 from k to k, and the inference process must be detailed and affirmed by inductive principle. As soon as the imaginary unit I of Complex Number came out, the number set expanded to complex number.
A complex number and a logarithm, the real and imaginary parts of the horizontal and vertical coordinates. Corresponds to a point on the complex plane, and the origin is connected with it as an arrow.
The arrow shaft is positive to the X axis, and the resulting angle is the radial angle. The length of an arrow shaft is a model, and numbers are often combined.
Algebraic geometry triangle, mutual transformation try. The essence of algebraic operation is I polynomial operation.
The positive integer of I is the second time, and four numerical periods appear. Some important conclusions, remember the results skillfully.
The ability of mutual transformation between reality and reality is great, and the complex number is equal to transform. Use the equation to solve, and pay attention to the whole substitution.
On the geometric operation diagram, the addition parallelogram and subtraction triangle rule are judged; Multiplication and division operations, reverse and forward rotation, expansion and contraction of the annual module length. In the operation of triangular form, it is necessary to distinguish the radiation angle from the mode.
It is very convenient to take the square and make the square by using Di Mofo formula. The radial angle operation is very strange, and the sum and difference are obtained by product quotient.
Four properties are inseparable, equal sum module and * * * yoke, two will not be real numbers, and the comparison size is not allowed. Complex numbers and real numbers are very close, so we should pay attention to the essential differences.
The two principles of addition and multiplication in the theorem of permutation, combination and binomial are the rules that run through. It is combination that has nothing to do with order, and it is arrangement that requires order.
Two formulas, two properties, two ideas and methods. The arrangement and combination are summarized, and the application problems must be transformed.
It is common sense to arrange and combine together and choose the back row first. Special elements and positions should be considered first.
Don't worry too much, don't miss too much, and tying and inserting is a skill. Arrange the combinatorial identities and define the proof modeling test.
On binomial theorem, China Yang Hui triangle. Two properties, two formulas, function assignment transformation.
"Solid Geometry" is a trinity of point, line and plane, represented by cylindrical cone billiards. All distances start from points, and all angles are formed by lines.
Vertical parallelism is the key point, and the concept must be clarified in the proof. Lines, lines, planes, planes and three pairs are circulated.
The whole idea of equation is solved, and it is reduced to consciousness. Before calculation, it is necessary to prove and draw the removed figure.
Auxiliary lines of solid geometry, usually vertical lines and planes. The concept of projection is very important, and it is the key to solving problems.
The dihedral angle of a straight line with different planes and the volume projection formula are vivid. The axiomatic nature is three perpendicular lines, which solve a lot of problems.
Plane Analytic Geometry: Directed line segment, straight circle, elliptic hyperbolic parabola, polar coordinates of parametric equation, and combination of numbers and shapes are called paradigms. Descartes' viewpoint pair, point and ordered real number pair, the two correspond, creating a new way of geometry.
The two kinds of thoughts reflect each other and turn into thoughts to fight the front; It is said that the undetermined coefficient method is actually the idea of equations. The three types are summed up, and the curve is drawn to find the equation, and the curve and the relationship between the curves are given to the equation.
Four tools are magic weapons, with good coordinate parameters; Plane geometry can't be lost, and the complex number of rotation transformation can be found. Analytic geometry is geometry, and you can't get carried away.
Graphics are intuitive and detailed, while mathematics is mathematical. In the Northern Zhou Dynasty of Sui Dynasty, when the history learning formula was flourishing, it reached 58 1, and it was a consort Yang.
