Owners of high-altitude vehicles with smoking habits often carry lighters with them. If you, like Mr. Zhang, forget to take the lighter out of the car during a hot day, then a lighter explosion may occur at any time. Once it explodes, the resulting flames come in contact with flammable substances and may even cause spontaneous combustion of the lift truck . It should be noted that there are many spontaneous combustion phenomena caused by the explosion of a lighter in the car. In addition, flammable and explosive materials such as perfume bottles, sealed beverages and sprays are also the main culprit, especially in the case of high-temperature exposure, the possibility of such items exploding is very high.
Relieve the crisis: Remind those careless car owners to check whether there are such dangerous goods left in the aerial vehicle before getting off the train.
Aerial boom crisis
Xiao Xu, the owner of the aerial vehicle, walked down in the scorching sun. Suddenly, he noticed a problem in the rear wheel. Many years of driving experience told him that the wheel was punctured. He slowly parked his car behind the speed bump and called the trailer.
Xiao Xu's approach is very correct. He must not step on the brakes after finding a puncture, and should stop the car after slowing down. There are many reasons for causing a flat tire, especially in the summer, because the conditions for using the tire are worse than before, and the possibility of a flat tire is even greater.
Relieve the crisis: Remind those owners who have been working long hours in the hot sun to try to control travel time and avoid high temperatures. If you need to drive in the hot sun for a long time, then allow the vehicle to cool down at regular intervals, and avoid using cold water to rush the truck and tires that have just been exposed . In addition, regular inspection of the tires is also very important.
Stable isotopes are naturally occurring isotopes that their radioactivity cannot be detected by current techniques.Compared with the tracer technique of radioactive element, stable isotope technique has no radiation damage, and it is not affected by half-life period, which can be applied to long time tracer experiment, and its quantitative test has high accuracy.
In the nuclear industry, 10B can be used to produce neutron counters, reactor control rods, and thermal neutron shielding materials. In the medical field, boron neutron capture therapy method is a new radiotherapy method for cancer treatment based on the ability of B10 for capturing thermal neutrons. As a dopant, 11B can be applied in the semiconductor industry, which makes silicon ion layout closely, so that the highly integrated and high-density microchips can be produced. 11B canbe used to produce neutron counters, reactor control rods, and thermal neutron shielding materials.
