The autumnal equinox is the sixteen thirteen solar terms in the solar terms of the lunar calendar. It is a special solar term. The following are all about the equinoxes.
Autumnal (autumnal equinox), the sixteen thirteen solar terms in the solar terms of the twelfth lunar calendar, usually on September 22 or 23 of each year. The climate in the south began in this autumn. One is that the sun reached 180 degrees of the Yellow Sutra on this day, and it directly hit the Earth's equator. Therefore, the day is divided equally between the day and night of the day, 12 hours each; the world is boundlessly poleless. After the autumnal equinox, the polar night range near the North Pole gradually increases, and the polar area near the South Pole gradually increases.
Equinox is also an important solar term for agricultural production. After the autumn equinox, the position of the direct sun moves to the southern hemisphere. The amount of solar radiation received by the northern hemisphere is decreasing, while the amount of calories dissipated on the ground is higher, and the rate of temperature decrease is significantly faster. The farmer said: "A cold autumn rain," "Bai Luqiu night, overnight cold night." “The Yanmen Gate opens in August, and the geese come under the feet of the frost.†It is not surprising that the equinoxes see the frost as early as the year in the Northeast.
Meteorologists said that according to the lunar calendar, “Liqiu†is the beginning of autumn, and “frost†is the end of the autumn. “Equinox†happens to be half of the 90 days from Liqiu to Frost. From the day of the equinox, the climate presents three major characteristics: the direct sunlight continues to move from the equator to the southern hemisphere, the phenomenon of short-duration in the northern hemisphere will become more and more apparent, the daylight will gradually become shorter and the night will become longer (until the winter solstice reaches The longest in the night and the shortest in the daytime; the temperature difference between day and night will gradually increase, and the amplitude will be higher than 10°C; the temperature will decrease day by day, become colder day by day, and gradually enter the autumn season. In the Southern Hemisphere, the opposite is true.
The characteristics of rapid cooling in the fall make the autumn harvest, autumn farming, and autumn cropping of the “three autumns†extremely busy. The autumnal cotton bolls and the tobacco turns from green to yellow, which is an excellent opportunity for harvesting. In North China, winter wheat has been planted, and the Yangtze River basin and the vast southern regions are busy harvesting late rice, clearing the land and preparing for rapeseed sowing. The lack of dry rain or continuous rain during the autumnal equinox is the main unfavorable factor affecting the normal implementation of the “three autumnsâ€. In particular, continuous rain may cause the upcoming crops to fall down, moldy or germinate, causing serious losses. "Three Autumns" are busy and you are in the "early" word. Harvesting the harvested crops in a timely manner can be protected from the dangers of early frost and continuous rain. Early timely sowing of winter crops can make full use of the pre-winter heat resources and nurture strong seedlings to safely overwinter for the next year to lay a foundation for high yields. “The autumn equinox does not reveal its head and it cuts the feed for the old cows.†The southern double-season rice is heading for flowers, which is a key period for the formation of yields. The “Ecstachy†weather formed early in the low temperature and rainy weather is the main threat to the late-night flowering and must be taken seriously. Do a good job in forecasting and defensive work.
Equinox solar health points
According to the motherland's medicine, the physical activity of the human body must adapt to changes in the yin and yang of the natural world. Therefore, the autumn should pay special attention to maintaining the yin of the guardianship. The principle of “relying on income†cannot be removed for accommodation, diet, spirit, and exercise.
In autumn, nature's yang changes from dredging to convergence and closing. People's daily routines need to be adjusted accordingly. "Q. Q. The Four Seasons Regulates God": "Autumn in March, early morning and early morning, with chicken "Early morning, in order to comply with the fine collection, in order to raise" close "gas; early rise, in order to comply with the yang long comfortable, so that the lung can be stretched.
1, autumn health "lung" first
Dryness is the main gas in autumn, and in ancient times, our country has the concept of “drying and injuring the lungs.†This is the time when the human body is vulnerable to dry spells and injure the lungs. Therefore, the health of the first autumn has the lungs.
Dry evil invasion will make people sick, often called "Qiuzao." If you do not pay attention to health in the fall, when the temperature and humidity changes greatly, the body's resistance will drop, the most common illness is a cold, cough. At the beginning, the nasopharynx felt dry, followed by dryness and discomfort. Afterwards, it appeared itchy throat, dry burning pain, dry cough and less sputum, coughing or bloody sputum, called "dry cough." If the "dry cough" treatment is not timely or adverse, it will lead to bronchitis, bronchitis, and make the lungs more injured.
Qiuzao can be further divided into "dryness" and "dryness." After the autumnal equinox, the cold evil gradually wins, which means the air-conditioning is compelling. Therefore, at this time, dry-blooded lungs are called dryness. The results of dryness and evil cause loss of Yinjin, dry skin and body fluid loss, and other symptoms, but also cause skin itching, hair withered, constipation and other symptoms. Therefore, the autumn health lungs first.
2, can not forget the warm stomach
After the autumnal equinoxes, the climate is getting cooler, which is also the season of multiple gastrointestinal diseases and recurrence. Special attention should be paid to keeping the stomach warm. Add clothes at a proper time and cover the quilt at night. Do not eat cold, too hot, too hard, too hot, too sticky food, but avoid too much overeating, to quit smoking. The best time to take medicine is to prevent the exacerbation of the gastric mucosa and cause the disease to deteriorate. According to the medical science, the gastrointestinal tract is very sensitive to cold stimulation. Paying attention to shelter protection and dietary patterns of life will effectively reduce the recurrence of related diseases.
3, after the equinoxes of the autumn equinox, the climate is gradually cooler, which is the season of intestinal infectious diseases and JE.
Autumn also often causes many relapses of old diseases, such as the relapse of chronic bronchitis and asthma in the elderly. If middle-aged and elderly people suffering from hypertension, coronary heart disease, and diabetes are neglected to prevent, they will increase the risk. Please pay more attention to everyone.
Second, living health
After the beginning of autumn, stay up late to balance, and stay up late to cool, you should adjust your own schedule, from the early summer to get up early, overto the "early morning to get up early", do not covet for the early morning cool and lazy bed. Get up early to avoid getting cold and get up early to take in fresh air. Get up early around 6-7, moderate exercise, so that yang can be declared.
Spring and autumn frozen
During the autumnal season, when the weather turns cold, care should be taken to keep warm: when it is cold, clothing is added, and when it is dry, it can be reduced. It should also be appropriate to “fall and freezeâ€, not to rush to add more clothes, focus on cold-resistant exercise, in order to enhance the ability of the heart and lungs to adapt to changes in the weather.
Health can not "eat a hungry meal thirsty"
When you are thirsty for drinking water and hungry for food, it seems to be natural, but it is not reasonable to use it for health.
Qiuzao: Drink water without thirst! Adhere to active daily replenishment of 1500 ml, is beneficial to anti-Qiuzao, improve lung function, promote blood circulation, prevention and treatment of the autumn.
Third, sports health
After a few autumn rains, the temperature dropped, and after experiencing the hot summer heat and wet stuffiness, people felt the coolness and comfort of autumn. Pleasant autumn is also the golden season for exercise. Hiking, jogging, walking and playing are all suitable sports. You can also choose to play Tai Chi, do Baduanjin, practice aerobics and other projects. To the heart and soul Kangtai effect.
IV. Spiritual rehabilitation
In the autumn, the weather gradually dries up, the sunshine decreases, and the temperature gradually decreases. People's emotions are inevitably a kind of coveted feeling. Therefore, there are words of “falling autumn rain and falling rainâ€. Therefore, at this time, people should maintain their peace of mind and conciliate their aura, avoiding the irritations of nervousness, anxiety, and irritation, and slowing down the influence of Qi and chill on the human body.
Chinese medicine has long said that "smiles and lungs". Different degrees of laughter have appropriate coordination effects on the respiratory organs, chest, abdomen, internal organs, muscles and other organs. Laughter can regulate emotions, but also to promote the lung, promote heart and lung function, kill more than one, why not do it.
V. Diet nursed back to health
Because the fall is lung gold, sourness can be convergence of lungs, pungent diarrhea can spread diarrhea, and should not be scattered in the fall, so try to eat less onions, ginger and other pungent products, appropriate to eat more sour and cool moisture products, such as: Lily, white fungus, yam, autumn pears, wolfberry, persimmon, sesame, duck, etc., to lungs and fluid, nourishing Yin Qing dry.
The automatic biochemical analyzer is an instrument that measures a specific chemical composition in body fluids according to the principle of photoelectric colorimetry. Due to its fast measurement speed, high accuracy and small consumption of reagents, it has been widely used in hospitals, epidemic prevention stations and family planning service stations at all levels. The combined use can greatly improve the efficiency and benefits of routine biochemical testing.
principle
The automatic analyzer is to automatically run all or part of the steps of sampling, mixing, warm bath (37°C) detection, result calculation, judgment, display and printing results and cleaning in the original manual operation process. Today, biochemical tests are basically automated analysis, and there are fully automatic biochemical analysis systems designed for large or very large clinical laboratories and commercial laboratories, which can be arbitrarily configured according to the laboratory's testing volume.
Whether it is the fastest-running (9600Test/h) modular fully automatic biochemical analyzer today, or the original manual-operated photoelectric colorimeter for colorimetry, the principle is the use of absorption spectroscopy in spectroscopic technology. It is the most basic core of the biochemical instrument.
Optical system: is a key part of ACA. Older ACA systems used halogen tungsten lamps, lenses, color filters, and photocell assemblies. The optical part of the new ACA system has been greatly improved. ACA's beam splitting system can be divided into front splitting and rear splitting due to different light positions. The advanced optical components use a set of lenses between the light source and the cuvette to convert the original light source. The light projected by the lamp passes through the cuvette to bring the beam to the speed of light (unlike traditional wedge beams), so that the spot beam can pass through even the smallest cuvette. Compared with traditional methods, it can save reagent consumption by 40-60%. After the spot beam passes through the cuvette, the spot beam is restored to the original beam through this group of restoration lenses (wide difference correction system), and is divided into several fixed wavelengths (about 10 or more wavelengths) by the grating. The optical/digital signal direct conversion technology is used to directly convert the optical signal in the optical path into a digital signal. It completely eliminates the interference of electromagnetic waves to the signal and the attenuation in the process of signal transmission. At the same time, the optical fiber is used in the signal transmission process, so that the signal can achieve no attenuation, and the test accuracy is improved by nearly 100 times. The closed combination of the optical path system makes the optical path without any maintenance, and the light splitting is accurate and the service life is long.
Constant temperature system: Since the temperature of the biochemical reaction has a great influence on the reaction results, the sensitivity and accuracy of the constant temperature system directly affect the measurement results. The early biochemical instruments used the method of air bath, and later developed into a dry bath with constant temperature liquid circulation which combines the advantages of dry air bath and water bath. The principle is to design a constant temperature tank around the cuvette, and add a stable constant temperature liquid that is odorless, non-polluting, non-evaporating and non-deteriorating in the tank. The constant temperature liquid has a large capacity, good thermal stability and uniformity. The cuvette does not directly contact the constant temperature liquid, which overcomes the characteristics of the water bath type constant temperature being susceptible to pollution and the uneven and unstable air bath.
Sample reaction stirring technology and probe technology: The traditional reaction stirring technology adopts magnetic bead type and vortex stirring type. The current popular stirring technology is a stirring unit composed of multiple groups of stirring rods that imitate the manual cleaning process. When the first group of stirring rods is stirring the sample/reagent or mixed solution, the second group of stirring rods performs high-speed and high-efficiency cleaning at the same time. The set of stirring bars also undergoes a warm water washing and air drying process at the same time. In the design of a single stirring rod, a new type of spiral high-speed rotating stirring is adopted, and the rotation direction is opposite to the spiral direction, thereby increasing the stirring force, the stirred liquid does not foam, and reducing the scattering of light by microbubbles. Reagent and sample probes are based on the principle of early capacitive sensing, but slightly improved to increase the alarm of blood clots and protein clots, and re-test results according to the alarm level, reducing sample aspiration errors and improving the reliability of test results. . Large-scale biochemical instruments can detect more than 1,000 tests per hour, so automatic retesting is very important. Subjective evaluation of test results and manual retesting can no longer meet clinical needs.
Other aspects: barcode recognition of reagents and samples and computer login. Due to the lack of barcode recognition function of early biochemical instruments, there are more opportunities for errors. In recent years, both imported and domestic chemical instruments have adopted barcode detection. The use of this technology in biochemical instruments has provided technical support for the development of high-speed ACA, and also made the instrument quite supportive. The software development is simple and easy, therefore, barcode detection is the basis for the intelligence of the instrument. Open reagents, as an important factor for hospitals to choose models, whether the instrument supports open reagents is very important. After the reagents are opened, hospitals and scientific research units can choose their own reagent suppliers, and have a greater degree of freedom in measuring the price, the reliability of the test results, and the validity period of the reagents. Ion Selective Electrode Analysis Accessory (ISE), human serum and urine electrolyte indicators are very important, and hospitals can save money by adding ISE to the ACA system.
