CVs should be vigilant at 20kmThe CVS's failure at 20km could be caused by a variety of reasons, so it was necessary to be vigilant.
I. The reasons related to the structure and principle of CVS
1. ** Steel belt related issues **
- CVs were driven by steel belt friction. At a speed of 20km/h, if the ratio of the driving wheel and the driven wheel was abnormal, such as too large, it would be considered a slip. At this time, the oil cylinder will clamp the steel belt. During the process of gear shifting, there will be a sense of lag through the calculation of the electromagnetic valve and oil pressure. From the slipping of the steel belt to the non-slipping, there will be a speed change, resulting in a setback.
2. ** Simulate the characteristics of shifting gears **
- Although CVs were infinitely variable, there were simulated shifts, such as six, seven, eight, and so on. At 20km, if it was at the node of the simulated gear shift, because it was not the real gear full transmission, there might be a setback during the gear shift.
II. Reason related to other parts
1. ** Engine problem **
- When the output power of the engine is insufficient, for example, after the engine has serious carbon pollution, if it needs to be upshifted at a speed of 20km/h, the load will increase, and the cylinder may have a slight fire phenomenon. This would cause the angular velocity of the output end of the crank shaft to be unequal in a unit of time, causing the vehicle to falter. Even if the root of the problem was the engine, it would appear as a CVS falter.
2. ** Transmission internal fault **
- Failure of the internal friction plate of the transmission may cause a setback at 20km. In this case, it is necessary to go to the 4S shop for maintenance.
- Transmission fluid problems could also cause a setback, which could be solved by changing the oil.
- The failure of the oil pump may also be the cause. If the damage is not serious, special temporary treatment methods can be used (such as applying soap on the damaged part, separating the damaged pump membrane from the intact pump membrane, staggering the damaged part and reinstalling it). If the damage is serious, it needs to be replaced.
- The response speed of the transmission was not fast enough. At 20km, if the speed of the upshift could not keep up with the speed of stepping on the accelerator, there would be a sense of frustration at the moment of shifting. At this time, you could try to step on the accelerator slowly.
- Insufficient grease could also cause a setback at 20km. Adding new oil could solve the problem.
3. ** Energy recovery system involved (if the vehicle has such a system)**
- At 20km, if the driver released the accelerator pedal or stepped on the brake pedal, the generator would immediately work and put a burden on the engine, affecting the engine speed, causing the engine speed to be out of sync with the clutch plate speed, resulting in a setback. In this case, it was necessary to go to the repair shop for repair.
4. ** Low-speed frequent gear change (if applicable)**
- If the 20km was in a low speed state and the vehicle frequently switched between the first and second gears (simulation), the clutch would be constantly separated and combined, and the power transmission could not be completed smoothly in a short period of time, resulting in a setback. In this case, when driving at low speeds, one had to avoid frequent switching between first and second gears.
5. ** Electromagnetic valve oil circuit problem **
- If the oil circuit of the electromagnetic valve is not smooth, the movement of the valve core up and down to cut the magnetic induction line will be hindered, resulting in the oil pressure adjustment being insensitive, and there may be a setback at 20km.

Heatstroke, cold body, be vigilantIt was common to feel cold after a heatstroke. This was because one was in a state of high fever and would show fear of the cold in the normal environment. When this happens, you need to be vigilant. First, you should take physical measures, such as adding clothes, avoiding going out and resting in bed. He could take Huoxiang Zhengqi Water to alleviate the symptoms. If the fever is serious, fluid replacement, lysinyl-adrenaline should be used to reduce the fever, and the patient's Lymph nodes should be wiped with a warm towel. At the same time, pay close attention to the development of symptoms. If the symptoms worsen or there are signs of severe heatstroke such as consciousness disorder, muscle convulsions, convulsions, etc., you must call 120 for emergency treatment in time.

At 19 weeks, the fetus is not active. Be vigilant.There were many reasons for the fetus to be inactive at 19 weeks of pregnancy. It needed to be considered comprehensively, but there was no need to be overly alarmed.
First of all, during this week of pregnancy, most pregnant women could feel the fetal movement, but the fetal movement was not very obvious. If the abdominal fat of a pregnant woman is thicker, she may only feel slight fetal movement occasionally, or even sometimes not feel it. This is a normal phenomenon.
Secondly, the difference in the time when the fetal movement appeared also had an impact. Some of the fetus 'movements appear earlier, and at 19 weeks, the fetal movements may be obvious and frequent; but if the fetal movements appear later, they may not be very active at 19 weeks, which may also be normal.
In addition, there were differences in the personality of the fetus. Some of the fetus were lively and loved to move, and the fetal movement was large and obvious; while some of the fetus were lazy and introverted, and the fetal movement was relatively weak and not so active.
Also, the mother's living conditions would also affect the perception of fetal movement. If the pregnant mother was always standing or walking, busy, and did not focus on the fetal movement, she might feel that the fetus was not active, but in fact, the fetus might have fetal movement but was not noticed. When the pregnant mother rested, sitting or lying for more time, she might feel more fetal movement.
However, if the fetus had no fetal movement at all, or was accompanied by other abnormal symptoms such as abdominal pain, menstrual bleeding, etc., it could be that the fetus had stopped breeding, or it could be a serious problem such as fetal oxygen deficiency (fetal oxygen deficiency could affect the development of the fetus 'brain and even cause the fetus to die in the womb). In this case, he had to go to the hospital in time for a B-ultrasound examination and listen to the fetal heart rate with the fetal heart stethoscope to understand the fetal heart rate and fetal movement of the embryo or fetus in the womb, as well as whether there were abnormalities in the umbilical cord, the umbilical fluid, and the placenta. If the examination shows that the fetus is in good condition in the womb, dynamic observation can be made; if there is no fetal heart rate or no obvious fetal heart rate through auscultation, it is considered that the fetus has stopped developing and the pregnancy should be actively terminated.

The skin is burning and painful, so be vigilantWhen there was burning pain on the skin, the diseases that needed to be vigilant were hormone dependent facial hemorrhoid and shingles. Hormone-dependent skin irritation on the face was caused by long-term use of hormones. It would destroy the skin's surface barrier, causing the skin to become more sensitive, causing local burning pain and other discomfort symptoms. Shingles was a viral infection. In addition to the skin, it was also accompanied by pain in the nerves. If there is no answer in the given information, answer "I don't know".
Wechat detected continuous abnormalities, be vigilantWhen WeChat detected continuous abnormalities, it was indeed necessary to be on high alert. This could be reflected in many aspects, such as continuous logins from other places. For example, in the case in document 4, the hacker used the account password obtained from the phone to log in to other people's WeChat on the new device. The account owner would receive a risk warning for logging in from other places. If there were continuous abnormal logins from other places, there was a high risk that the account had been stolen.
It could also be an abnormal operation such as sending frequent messages. This might be the hacker using the account to carry out fraud activities, such as sending money to friends, asking for personal information, etc. This not only damaged the reputation of the account owner, but also may cause the loss of the friend's property.
In addition, if there were continuous abnormalities in Weixin Pay, such as receiving continuous payment risk warnings, it might be that the security of the account had been threatened and there was a risk of being used for illegal transfers and consumption, just like how the hacker cracked the payment password and made a small transfer to avoid risk control. Therefore, once WeChat detected continuous abnormalities, users should take timely measures, such as changing passwords, contacting WeChat customer service, etc., to ensure the security of their accounts and their own property.

Albendazole-induced fever should be vigilantAs a broad-spectrum anthelmintic, albendazol had certain adverse effects, including fever. In addition, some parasitic infections could also cause fever.
Based on the pharmacology of albendazol, it was rapidly digested after entering the human body, blocking the parasite's absorption of glucose and a series of other effects to deworm the parasite. However, this process may cause some body reactions, such as fever. When fever occurs after taking albendazole tablets, you should be wary of possible adverse drug reactions.
At the same time, consideration should also be given to the possibility of misdiagnosis of other diseases and the use of albendazole. For example, myparasitism may have headache and fever as the first symptoms, and the percentage and absolute value of peripheral blood eaosophils may be increased. If no worms are found, it is easy to be misdiagnosed as other diseases and treated with albendazole.2 Therefore, if fever symptoms appear after taking albendazole tablets, it is necessary to make a comprehensive judgment whether it is caused by the disease itself (such as parasitic infection that has not been effectively controlled) or the fever caused by adverse drug reactions. If necessary, stop taking the medicine and seek medical advice in time.

40-year-old with white hair, be vigilant40-year-olds with white hair at the temples may need to be wary of the following situations:
1. ** Deficiency of Qi and blood **: If there is a deficiency of Qi and blood, the nutrition cannot nourish the hair, which may lead to white hair at the temples. Under the guidance of a doctor, you can take the Eight Treasures Pill and other qi and blood replenishing drugs for treatment. However, it is forbidden for those who are allergic to the Eight Treasures Pill. It is not suitable for patients with cold and fever.
2. ** Heat in the liver and gallbladder **: When the heat in the liver and gallbladder is high, the body fluid will burn and cannot rise to the head and the sides of the liver meridian, causing the temples to turn white. It can be treated by taking drugs such as Longdan Xiegan Pill to clear liver and gallbladder heat, but it is prohibited for those who are allergic to this product. Pregnant women and those with stomach cold should be used with caution.
3. ** Kidney Yin Deficiency **: If the kidney yin fluid is insufficient, it cannot flow to the head to nourish the hair. It can also cause white hair at the temples. You can take Liuwei Dihuang Pill and other yin nourishing drugs. Those who are allergic to this product are prohibited. It is not suitable for patients with cold and fever.
4. ** Bad Living Habits **: Long-term bad living habits, such as smoking, drinking, staying up late, often eating heavy-tasting food, too much pressure, low mood, etc., may not only cause white hair to appear earlier, but may also increase white hair.
5. ** Often picky about food and partial eclipse **: Hair needs a variety of nutrients, such as potassium, vitamins B, a variety of minerals, etc., often picky about food and partial eclipse, lack of these nutrients will affect the formation of dark, resulting in white hair.
6. ** related diseases **: If it is not caused by the above factors, be wary of related diseases, such as hormonal system diseases (hyperactivity, hypoactivity, wasting diseases, etc.). These diseases may damage the health of scalp hair bulbs and cause partial white hair.
7. ** Genetic factors **: Part of the premature aging white hair disease is related to genetics. White hair is still white after being pulled out. At present, there is no good way to deal with it. It can only be improved by dyeing hair.
