Vitamin B2, safe "nuclear" weapon

Vitamin B2 has a wide range of effects:

1. Promote development and cell regeneration;

2. Involved in the growth and metabolism of cells;

3. With other substances in a variety of metabolism;

4. Promote growth and development, maintain skin and cell membrane integrity;

5. Prevent and eliminate oral reproductive syndrome;

6. Promote normal growth of skin, nails, and hair;

7. To promote the body's absorption of iron, can prevent anemia;

8. Improve vision and reduce eye fatigue. Vitamin B2, also known as riboflavin, is a safe "nuclear" weapon.

Note: Oral Reproductive Syndrome, also known as Behcet's disease, is characterized by oral ulcers, genital ulcers, ophthalmia, and skin lesions. The disease often affects the nervous system, digestive tract, lungs, kidneys, and epididymides, and the condition is repeated. Alternation of attacks and remissions.

Vitamin B2 has three characteristics: First, it is easily damaged by light (especially ultraviolet light); second, it can be destroyed by heating in alkaline solution. Therefore, it needs to pay more attention to the use of food and drugs. Third, the body reserves are limited and must be supplemented daily. .

We usually supplement vitamin B2 daily with food or nutritional supplements, and it works better with vitamin B1, vitamin B6, vitamin C, and folic acid. Some special patients can use drugs to supplement. Under normal circumstances, vitamin B2 does not accumulate in the body, so even if it is taken in excess, it will not be poisoned.

Vitamin B2 is widely used

Vitamin B2 has a wide range of effects. In addition to the aforementioned growth-promoting, anti-anemia, and visual acuity, the study found that it has the following uses:

1. Treatment of patients with angina pectoris Coronary heart disease, myocardial ischemia and angina pectoris, each serving vitamin B2 75 mg, 3 times a day, after 2 to 3 months of medication, the frequency of angina pectoris is reduced. Pharmacological studies confirm that vitamin B2 can improve heart blood supply by participating in energy metabolism in the body. In addition, vitamin B2 can also inhibit platelet aggregation, improve myocardial ischemia and reduce the scope of myocardial infarction, improve myocardial function, there is a great future in the protection of the heart!

2. Migraine is caused by a decrease in the brain's energy reserve or by a strong cerebrovascular accident. Recent studies have shown that large doses of vitamin B2 can reduce the frequency of migraine attacks and shorten the duration of attacks. Taking 200 to 400 mg of vitamin B2 per day as prescribed by the doctor can effectively prevent migraine headaches and at least reduce the frequency and degree of attacks. Those who have a history of migraine can use prophylactic applications in appropriate amounts. The combination with magnesium agent Pan Jinnan (editor's note: potassium magnesium aspartate) is more effective.

3. Improve ***ual life Vitamin B2 is related to the quality of ***ual life, especially women. Vitamin B2 deficiency can be expressed as vaginal dryness, vaginal muغير مجاز مي باشدal hyperemia, ulceration, susceptibility to cheilitis, vaginitis, skin was scaly, rough skin, exfoliation of the outer skin, increased exudation, can be extended to the near thigh ... ... Causes loss of libido, frigidity, and ***ual pain. Therefore, women (especially reproductive period) should pay attention to the supplement of multivitamins, including not only vitamin B2 but also folic acid.

4. Pharmacological studies on the prevention and treatment of benign prostatic hyperplasia have shown that vitamin B2 has a beneficial effect on urinary detumescence and is helpful in eliminating symptoms such as poor micturition. Patients with benign prostatic hyperplasia can take 50 mg of vitamin B2 every day. After six months, the symptoms can be improved. The hypertrophy of the prostate can also be reduced. It is particularly suitable for patients with prostatic hypertrophy and edema.

5. To enhance cold resistance Vitamin B2 combined with vitamin E and iron can enhance the body's ability to withstand cold. This is because they can all participate in and enhance the energy metabolism of the human body or participate in the human hematopoietic process, and its comprehensive effect is to promote the body's prolific fever and achieve cold-proof purposes.

6. In addition, the study also found that vitamin B2 has certain anti-cancer effects and prevents nephritis edema.

Vitamin B2 food supplement is enough

Vitamin B2 is mainly found in animal foods such as dairy products, eggs, lean meats, and animal livers. Insufficient intake of vegetarians or animal foods can cause vitamin B2 deficiency. As long as there is a reasonable diet, it will not be lacking.

If there is a lack of vitamin B2, choose milk and its products, animal viscera (liver, kidney and heart, etc.), egg yolk, a variety of fish (especially squid, squid, etc.), spinach, carrots, mushrooms, seaweed, eggplant, Vegetables such as celery and tomatoes, oranges, and mandarin oranges are usually consumed without additional supplements.

In late February, Shandong Shuanglun Group Co., Ltd. launched a four-day closed special session. The theme of the four-day theme conference is only one, which is closely related to the unified deployment of the “Year of Quality Project Construction” and “Year of Independent Innovation” determined by the Municipal Party Committee and the Municipal Government in 2008, and discusses the company's future development goals and directions.

“2008 is the Chinese year of the world and is the year of the Olympics in China. This provides us with a tremendous opportunity for development. The year of quality project construction and the year of independent innovation proposed by the municipal party committee and the municipal government have provided the impetus for the development of our company. We must seize this rare opportunity for development and create a new breakthrough in 2008, said Yao Hongchun, chairman of Shandong Double Wheel Group Co., Ltd.

The two-wheel group is a high-tech enterprise of the National Torch Plan and a national credit-worthy contract-holding enterprise. It has more than 100 offices and distributors in large and medium-sized cities throughout the country, forming a nationwide marketing network. The products are exported to North America and the Middle East. , Southeast Asia, Europe and many other regions, and with high-quality products and efficient and comprehensive services widely favored by users, its product trademark "two-wheel" is China's pump industry's first well-known trademarks.

Yao Hongchun is not satisfied with this: “The two-wheel group has indeed achieved certain results in recent years, but there is still a huge gap between the company’s scale and production capacity and the world’s pump giants ITT and Japan’s Ebara. In terms of the production capacity of large-diameter pumps and special pumps, there is also a large gap between Shenyang Pump Factory and foreign companies in some special fields such as national petrochemical and power stations, which still occupy most of the market share. 3 to 5 times."

The two-wheeled group turned the gap into momentum. The Group has hired well-known engineering and technical personnel in the industry to the company to lay a solid foundation for the development of the company. At the same time for many years, we employ well-known experts and professors from the domestic machinery industry as special consultants for enterprises to provide constructive opinions and suggestions on the development of the industry and products. “This year we have identified new business and product development directions and goals. Our goal is: an expansion, two subdivisions, and three improvements. That is, expanding the production of the parent company of the Group’s subsidiary, Fender Pumps Co., Ltd., Sales capacity, subdividing products, segmenting markets, improving product quality, increasing production capacity, and increasing the speed of business development.” Yao Hongchun stated that in 2008, the Group determined that the economic indicators of the two-wheel pump Co., Ltd. of Fender were higher than those of 2007. To double, and plan within 3 years, various economic indicators strive to double each year, and develop the subsidiary to show itself as a window to the international pump industry. At the same time, in accordance with the development trend of petrochemical and power station industries at home and abroad, we plan to invest RMB 30 million in 2008 to establish Shandong Double Wheel Fluid Machinery Co., Ltd. to produce and design petrochemical and power station industry pumps with independent intellectual property rights. “We will also combine the characteristics of foreign markets for the demand for pump products and build a new industrial park dedicated to the production of large and medium-sized export products in the region. In addition, we have launched Zhangcun in order to fully improve the company’s special material casting level and capabilities. The construction of the second phase of the factory area. In the near future, the two-wheel brand will become the best brand in the domestic pump industry and become a well-known brand in the international pump industry.” Yao Hongchun is very confident.

Picture distortion and interference

In the video surveillance system, video signal transmission, whether using coaxial cable or digital network cable, in the transmission process, once the external interference signal intrusion, usually affect the picture quality, thereby reducing the monitoring effect. In the surveillance system, there are many reasons for video interference and noise, and it is difficult to fully and clearly summarize. However, it is certain that these interferences and noises come from both the equipment itself and the external environment. For different noise and interference, the method of exclusion is not the same. If it is the reason of the equipment itself, it usually can be solved simply by replacing the faulty equipment; however, it is more difficult to deal with interference signals caused by external lines and the environment. Next, we will analyze each of the twelve major phenomena mentioned above one by one in order to deepen the reasons for their occurrence.

The color of the video image is distorted and twisted: usually this problem is caused by a short circuit between the positive and negative electrodes after the analog coaxial cable is connected to the video, or after the coaxial core wire is bent, the micro-touch contact connector housing may be on the twisted pair transmission. The positive and negative poles of the converter of the transmitting end and the receiving end are connected inversely. In addition, it is also possible that the signal pins of the network line are connected incorrectly. This kind of problem will not damage the equipment, and only the positive and negative polarity can be changed;

The horizontal white or black ripple of the video screen moves toward the top of the screen: this is mostly caused by insufficient voltage, but in some cases, the AC voltage of the power supply is low, and the voltage drop exceeds the rated operating voltage of the camera or DVR by more than 10%. , Or DC power supply failure so that the voltage from 12V DC to 9V below will cause the screen to move. In addition, it may also be caused by a decrease of the current from the supply limit to a current condition in which the load device cannot be operated or a current harmonic generated by the power supply increase;

· Multiple black horizontal lines appear on the video screen: The phenomenon is caused by the signal lines being too thin, the cable pulling distance too long to cause the signal to be weak, or the signal distributor without amplification compensation is used;

There are two overlapping scenes on the video screen: this signal called “ghosting” has secondary reflections. This phenomenon is also known as overlap shadowing or afterglow. Most of the problems are caused by incorrect cable impedances or short circuit lengths. Delayed reflections; it is also possible that there are too many signal assignments, causing signal reflection delays;

Twill or right-to-left twill stripes appear on video: This type of twill or web-like interference appears on the video monitor. This kind of interference does not affect the normal image when it is light, but when it is serious, the video has problems with the general monitoring. This kind of phenomenon is numerous and complicated. First, the quality of the video transmission line may be poor, especially the poor performance of the shielding and isolation noise, poor quality of the isolation network, or the accumulation of noise due to a capacitive reactance caused by the aluminum foil plus the copper wire network; or the imbalance of the ground impedance is not 75Ω. Caused by floor wave noise entering the cable, if this part is serious, on the analog coaxial cable will produce an imbalance of the voltage to the ground, so that the cable becomes a capacitor case accumulation current, once the engineer touches the BNC connector will discharge, so that Engineers produce electric shock or discharge sparks to damage the equipment circuit; again, it may be due to the power supply system head and tail end not equal to the ground potential and the power source is not purely correct AC, but will also be caused by the wrong power phase. There is such interference; finally, there is a strong source of interference near the monitoring system, such as ground wave noise interference caused by high-frequency equipment or radio and television signal transmission towers in the vicinity;

Color and sound deviation

The color of the video screen becomes light and the colors are weird: In general, the problem is that there are many problems in adjusting the color saturation, but there are also problems caused by broken skin or poor grounding on the line.

The video screen jumps up and down continuously: If the next runout is not an excessively weak signal, the camera itself loses the level of the synchronization signal because of the adjustment of the grayscale signal; also, because the wire is not long enough during construction, the solder is not soldered during wiring. Welding, resulting in out of sync. In the case of multiple signals, the vertical sync signal caused by uneven intensity makes the screen jitter;

There are water ripples and bright spot noises on the video screen: This type of problem is mostly caused by poor aperture adjustment of the lens, but it is also possible that the field signal lines are disturbed by the external environment. Because the environment is often scattered with noise, resulting in the subtraction of the foreground and background, there are a lot of fragmented spots of non-moving objects, these spots will destroy the target information, and then cause the system to misjudgment, it is also one of the more difficult interference problems, but If simply refers to the bright spot noise, it may be the problem that the illumination can be solved by adjusting the aperture.

The video was originally in color format but turned black and white: even if it were a fool, the “stupid and naive” engineers would inevitably run into it. Since the current camera has the NTSC and PAL dual system selection function (whether analog or network surveillance cameras are all the same), some engineers found that after the camera was installed, the video could only display black and white images. It was just trying to check the lines. , monitors, and DVRs often ignore the camera's own system switching options. However, this is not an absolute and unique reason. It may also be the result of the group's resistance to changes caused by the short-circuiting of positive and negative poles of the line. Therefore, it must be carefully checked;

There are regular white highlights in the picture: this problem usually occurs when the video transmitter's line is poor or moisture in the connector penetrates into the fiber cable connector; of course, high-frequency devices can also cause the camera to produce such picture-interference noise, especially This phenomenon is most likely to occur in the near-range antenna of an FM AM radio station; in addition, poor monitoring of the grounding of the monitoring equipment may also occur.

In the dark areas of the video screen, bright colored patches of different colors, such as white, reddish or green, and blue, appear. The cause is similar to the previous problem, but this situation will only occur on digital optical transceivers, and its root causes Should be caused by improper processing of the signal demodulation circuit. The product quality of product manufacturers in this part will also affect the results of the project;

A second video interference situation occurs in video or sound: crosstalk is mainly caused by the mutual interference between the signal and the signal; it may also be caused by electromagnetic radiation between the signal wires, or transmitted from the power plane and the ground plane. The necessary signals are generated; it may also be due to the adjacent interference from the equipment or the excessive proximity between the cables and cables of different strengths and different types of signals.

After reading the above reasons, the reader may ask: It seems that such problems are not related to cables. This is true, because the quality of the cable construction is directly related to the quality of the project. Therefore, before discussing the problem of video noise interference, it is necessary to understand the influence of transmission of video frequency spectrum and coaxial cable on noise interference.
