3. Physical period: Uniform circular motion is a kind of periodic motion. The so-called periodicity refers to the fact that after a certain period of time, the moving object repeats back to its original position, and the instantaneous speed repeats back to its original size and direction. The time it takes for an object to move in a uniform circle is called a period. The period is expressed by the symbol T, and the period is also a physical quantity describing the speed of uniform circular motion. The long period indicates the slow motion of the object, while the short period indicates the fast motion of the object.
After this time the mines have come into play, The company commander also ordered us to take advantage of the gap between operations. To replace the mines that have already triggered the explosion with new ones, I was one of four people on this mission, I remember when I went down there, I saw the bodies of the dogs, I can't help but look at those who were killed by steel balls but were relatively complete.

In addition, As Zhang Xiaobo said, On the front line at that time, Wearing or not wearing a helmet is a "choice", Because Vietnam is located in Southeast Asia, The climate is hot and humid, Helmets are heavy and airtight, Wearing it is very easy to cause heatstroke, Particularly in fast maneuvers, This is the easiest way to do strenuous activities such as running. Therefore, in order for the troops to fight more efficiently, There would be no mandatory order for everyone to wear a helmet, If you don't want to wear it, you can choose to wear a cloth cap with eaves. So in the vast majority of relevant historical photos, Among our troops participating in the war, The highest percentage of helmets is worn by artillery, It is mainly used to defend the fragments of enemy artillery and various hard objects brought up by explosions in artillery warfare. Even some border militiamen wore helmets in large numbers, On the contrary, the impact is at the forefront, Infantry units carrying out a large number of mobile combat missions are rarely worn, Investigate its reason, It is for the infantry troops to carry out large-scale interspersed operations frequently. Exercise is enormous, It is really inconvenient to wear helmets, This approach has both advantages and disadvantages, It is not good to judge right or wrong here, but when facing such a horrible "killer bee" on the ground on 149, it is regrettable and regrettable that the heavy casualties caused by the low wearing rate of helmets have to be said. If they had worn helmets instead of military caps like Zhang Xiaobo, the casualties caused by the sting attack of "killer bee" would have been much smaller.
