kinetic energy head

基本解释

Hitting a dust mote-sized particle would impart the same kinetic energy as slamming head on into a speeding freight train.
与尘埃级别的颗粒相撞，都可能得到与高速货车迎面相撞的能量。
This is probably due to a combination of less kinetic energy and a greater ability to stabilize the head in headshot compared with boxing, " says Henrik Zetterberg."
这很可能是因为较小的动能和更大的使头部稳定的能力综合作用的结果。”Henrik Zetterberg说。
Then the turbulence characteristics of the spur dike head and backflow region and the distributions law of flow and turbulence kinetic energy around spur dike are obtained in this paper.
