The total kinetic resistance of a moving part (a firearm bolt) was acquired by experiment because water resistance was difficult to be got accurately.

因水阻力较难准确求得，可利用实验确定活动件(枪机)运动总阻力。

So the bugs go with the flow and offer little resistance. And the drop slows only slightly, keeping its kinetic energy rather than blasting the bug.

因此，小虫子顺其自然，使了一点小劲，然后雨点就略有放缓，不过仍保持着它的能量而不是使劲冲走小虫。

By using MR technology, MR damper, which has many notable advantages such as continuously controllable resistance and strong ability to consume kinetic energy, is widely used in many fields.

基于磁流变技术的阻尼器由于有耗能能力强、阻尼力连续可调的优点已被广泛应用于众多领域。
