▌作品介绍：随着高层建筑越建越多，当发生火灾时，怎样让人快速离开一直是世界难题。我想设计一把高楼逃生伞，当发生火灾时，立即打开逃生伞的开关，快速膨胀的高压气体在伞的下端形成缓冲气球，用来减缓到地面的冲击，打开的伞减缓了下降的速度。最后逃生伞沿着楼顶垂下的救生绳安全到达地面，使人们得以快速逃生。
此文自动翻译Introduction:As more and more high-rise buildings are built, how to make people leave quickly is always a difficult problem in the world when there is a fire. I want to design a high-rise escape umbrella. When a fire breaks out, open the switch of the escape umbrella immediately. The rapidly expanding high-pressure gas forms a buffer balloon at the lower end of the umbrella to slow down the impact to the ground. The open umbrella slows down the speed of descent. Finally, the escape umbrella reached the ground safely along the lifeline hanging from the roof, enabling people to escape quickly.
