According to my understanding, I will also say a sentence. In each F1 race, the tires of the car need to be heated with a heating blanket during the preparation period of the race, but the general heating blanket can only heat the tires to between 60 and 80 degrees Celsius, and the ideal working temperature of the racing tires during the race is about 100 degrees Celsius, between 80 and 110 degrees Celsius. If it is too hot, it is easy to wear out quickly and glue balls appear.
If it's too cold, there will be a lack of grip and the car will slip and slide sideways. The speed of the car is reduced. The temperature of the road surface generally does not exceed 50 degrees Celsius during the race, and once the heating blanket is removed, the temperature decreases quickly.
Therefore, there will be a warm-up lap, just to rub the tires on the track to make the temperature a little higher, so as to avoid too many accidents at the start because the tire temperature is too low. After changing the tires during the race, you also need to run two laps on the track, and the friction between the tires and the ground makes the tire temperature reach the working state. As for the problem that the heating blanket cannot be directly added to the working temperature, I think that the tire pressure of each track F1 racing car should be set according to the specific situation of the track and the road surface temperature, which is said to be accurate, and the car in the pit station in the case of low speed, after the tire and the road surface contact, the temperature drops quickly, so it is meaningless, too high will affect the use of the tire (tire pressure).
I don't know what the landlord thinks.

At present, there are two types of medical heating blankets in use in the country:
1. Inflatable heating blanket, this heating blanket is composed of a blower and a disposable blanket, the main principle is to blow up the disposable blanket through the ventilation pipe after the compressed gas of the blower is heated (just an air cushion bed), cover the patient's body, and heat the air through the small hole on the disposable blanket.
2. Carbon fiber thermal conductive 24V voltage electric blanket, the heating blanket is also a direction in the current world, taking into account safety at the same time, the effect is guaranteed, for repeated use, no consumables and waste, reduce the cost of patients and hospitals. The product has been used for decades in European and American countries, and China is currently represented by Jiangsu Bairun Medical.

Going to the hospital? Hit **, call someone? It's not an emergency, and the queue is half an hour, or even an hour or two.
I didn't expect the consultation to take only five to ten minutes, and it was over. Medical resources are too precious, but people's time is also precious. Go out with a mobile phone**, don't have to queue up for a long time when you get to the hospital, consult the doctor directly if you have questions, don't have to run to register a number in order to ask a few questions, don't have to squeeze in the front desk of the hospital to fill in the case information, or wait for the staff to enter the computer for you, all mobile phones go online to the platform, bind the social security card directly to the medical insurance, make a direct appointment for the next follow-up, and the medical staff can also evaluate the ...... if they are not seriousSave money, save roads, save time, save processes.
I won't talk about the rest.
The top dressing at the seedling stage was mainly light and light fertilizer; After the top dressing twice, the first time was from early June to early July, at this time is the long-term period of Sun Jiangwang, which is the peak period of ginger fertilizer absorption, 20 kg of compound fertilizer and 10 kg of urea per mu; The second time was in early September and early October, when the ginger tuber was rapidly expanding, and 30 kg of compound fertilizer and 10 kg of potassium chloride were applied per mu. >>>More

When Zheng He went to the West, the fleet was basically the most advanced ships at that time, and Zheng He used a total of more than 200 ships when he went to the West, and the types of ships were also very special. Some ships are loaded with **, some ships are loaded with silk, tea, vegetables, etc., and when Zheng He went to the West, a total of 27,000 people were used to accompany him, including soldiers, doctors, sailors, flag soldiers and all kinds of craftsmen, etc., the scale can be said to be very huge. <> >>>More
I don't think this can simply say whether it is good or bad, the social system is best only if it adapts to the social and economic development of the country, and the United States has a system of separation of powers, which has been established since the US Constitution in 1787 and has been used for more than 200 years, and it has developed very well, it should be said that this system is more suitable for the development of the United States itself. Residents of the country can elect independently**, enjoy more democratic rights, and the United States** is also more efficient. There are successes and failures in each session, and it cannot be simply said that it is a failure, Bush Jr. just adapted to the situation at that time, and was also intervened by many interest groups, and some people did not think that he was a failure, but looked at it from a different angle.
