What are the methods of milk withdrawal? The great gods help to milk. Small folk prescription: 1. Stir-fried malt back to milk, buy 60 ~120g of stir-fried malt in Chinese medicine shop, take it with water, take it with15g each time, twice a day, take it with warm water, and wean; 2. Radish seeds are effective for milk withdrawal, and radish seeds are also called radish seeds. After that, 30 grams of tobacco seeds will be broken, decocted in water and taken twice in the morning and evening. This is a daily dose and can be used repeatedly when the effect is not obvious. There are also weaned foods: malt extract, maltose, barley tea, raw cereal, ham meat, square leg meat, barley tea, maltose, leek, pepper, aniseed, monosodium glutamate, beans and ginseng. If you think it's too much trouble, you can go to the Taobao shop "Happy Life of Mi Ma and Xiao Mi Ma" to buy her nave's milk-returning soup and wean it for 3 days to prevent sagging.
What are the methods of physics experiment? The gods help me. Physical method is not only a method for scientists to study problems, but also a common method for students to learn physics. The new curriculum standard also requires students to master some physical methods to explore problems. The common physical method model method is to express abstract physical phenomena with simple and understandable concrete models. For example, the solar system model is used to represent the atomic structure, and simple lines are used to represent levers. Superposition method In physics, the same small and difficult physical quantity is often superimposed, and the method of averaging after measurement is commonly known as "superposition method". Among all kinds of phenomena in nature, the control variable method is often complicated. There are often many factors that determine the emergence and change of a phenomenon. In order to find out the reasons and laws of things changing, we must try to artificially control one or several factors to keep them unchanged, and then compare and study the relationship between the other two variables. This scientific method of studying problems is the "control variable method". This method is mostly used in junior high school physics experiments. For example, the current I through a conductor is influenced by the conductor resistance R and the voltage U across it. When studying the relationship between current I and resistance R, it is necessary to keep voltage U constant. When studying the relationship between current I and voltage u, it is necessary to keep the resistance r unchanged. There are some physical phenomena in the method of experiment+inference, which cannot be directly verified due to the limitation of experimental conditions. We need to experiment first, and then draw the correct conclusion through reasonable reasoning. This is also a common scientific method. If the alarm clock is placed in a sealed glass cover, when the air in the cover is taken away, the bell will become smaller, and it is inferred that vacuum cannot transmit sound. Some invisible and intangible physical phenomena of transformation method are not easy to know directly, but we often know them indirectly according to the phenomena they show. For example, according to the thermal effect of current to identify the size of the current, according to the strong role of magnetic field on magnets to identify the magnetic field. When studying physical problems, sometimes in order to simplify the problem, one physical quantity is often used to replace all other physical quantities, but it will not change the physical effect. For example, the resultant force is used to replace each component, the total resistance is used to replace the resistance of each part, and the buoyancy is used to replace the pressure of liquid on the object. Description for the convenience of studying problems, we often use lines and other means to describe various invisible phenomena. For example, light is described by light, magnetic field is described by magnetic induction lines, and force is described by graphics. When we know some physical concepts by analogy, we often compare them with familiar and common phenomena in life to help us understand them. If you know the magnitude of the current, use the analogy of water flow. When understanding voltage, use water pressure for analogy. Processing method of physical experimental data Experimental data is the basis of experimental quantitative analysis and the first-hand information for exploring and verifying physical laws. When the systematic error is certain, whether the experimental data is properly processed will directly affect the size of accidental error. Therefore, the processing of experimental data is one of the important contents of experimental review. This paper briefly introduces the processing method of experimental data with examples. 1. average method is a commonly used data processing method to reduce accidental errors. Usually, under the same measurement conditions, the results of multiple measurements of a physical quantity will not be exactly the same. It is the best approximation of the true value to use the arithmetic average of many measurements as the measurement result. 2. Listing the data in the list method experiment can concisely express the relationship between related physical quantities, which is convenient for checking whether the measurement results and operations are reasonable and helpful for finding and analyzing problems. The list method is also the basis of the image method. The following points should be paid attention to when listing: ① The table should directly reflect the relationship between related physical quantities. General independent variables are written in the front and dependent variables are written in the back, which is convenient for analysis. (2) The table should clearly reflect the number of measurements, the names and units of measured physical quantities, and the names and units of calculated physical quantities. The units of physical quantities can be written in the title bar, and generally do not appear repeatedly in the numerical column. ③ The data listed in the table should correctly reflect the significant figures of the measured values. 3. Drawing method selects appropriate independent variables, and through drawing, we can find or reflect the changing relationship between physical quantities, which is convenient to find out the law and determine the functional relationship of corresponding quantities. Drawing method is one of the most commonly used experimental data processing methods. The requirements for drawing an image are as follows: ① Choose the coordinate axis according to the measurement requirements, generally taking the horizontal axis as the independent variable and the vertical axis as the dependent variable. The coordinate axis should indicate the name and unit of the physical quantity it represents. ② The scale of the coordinate axis should be selected properly, so that the measured data can be accurately reflected on the coordinate axis. In order to avoid a large blank on the drawing, the coordinate origin can be zero or non-zero. The estimated reading of the division of the coordinate axis should correspond to the estimated reading of the measured value (i.e. the last significant digit).

What method can treat chilblain? Hello, great gods, the domain name movement elite group is happy to answer your question: chilblain has no specific medicine and is a common disease in winter. It is easy to occur in low temperature (below 10℃) and humid environment, and it recurs in winter and heals itself after the weather gets warmer. Cold is the root of frostbite, so it is very important to prepare for cold when winter comes. Especially limbs, such as hands, feet, ears, etc. It is mainly related to your personal physique, such as autonomic nervous dysfunction, poor blood circulation in limbs, sweating in hands and feet, etc. It is frostbite that grows easily. Therefore, it is very important to strengthen physical fitness and improve one's cold-proof ability. Domain name elite group reminds you to take part in physical labor and physical exercise frequently, such as running, in order to strengthen your physique and promote blood circulation. In addition, you can eat more high-calorie foods such as mutton and chocolate in winter, and you can also eat some wine and pepper to sweat and promote blood circulation. First of all, we must strengthen warmth. If chilblain is only a hard knot, it can be scrubbed with pepper tincture and hot alcohol when it is not broken. If it is broken, it can be rubbed with erythromycin ointment and lard honey ointment to promote its early healing. There is no quick cure for chilblain, and prevention is the key. So, I suggest you don't worry. Soaking hands and feet in warm water for about an hour every day is very helpful for relief and recovery. Change it slowly. It's no use being anxious. In addition, we should pay attention to prevention. In late autumn and early winter, use cold water to soak the parts that were often frostbitten in previous years, such as hands and feet. Soak for half an hour first and then for an hour every day, so that it is not easy to recur in winter. Secondly, pay attention to local warmth, such as using gloves, windproof earmuffs, scarves, etc. Wear warm shoes when going out in cold weather, but not too tight, which can effectively prevent frostbite. In addition, the domain name sports elite group suggested that you can eat some beef and mutton at the same temperature in late autumn and early winter to enhance your body's cold tolerance. If it is a person diagnosed as yang deficiency and internal cold by traditional Chinese medicine, Chinese patent medicines such as Liuwei Dihuang Pill can be taken orally as soon as possible for prevention. Rub chilblain cream 1 ~ 2 times a day, roast radish slices and apply hot compress, or go to a Chinese pharmacy and ask a pharmacist to prescribe a dose of Yaoyinzi stewed chicken soup, soak dried peppers in alcohol (forbidden for those with broken skin and ulceration), and drink a mouthful of red wine to increase blood circulation. If your hands are hot and itchy but not festering, you can put them together and rub them repeatedly between your thighs to keep them warm, or you can use a hair dryer. Beware of advertisements! Wish: health and happiness!
