The force and moment exerted on the solid body are expressed as the rate of change of the first-and second-order kinetic vorticity moments, respectively.

作用在任意运动物体（系）上的力和力矩可以分别表示成流场中动力学涡量的一阶矩和二阶矩随时间的变化率。

Then the inertia force is reduced by the inconstant acceleration, so that the static rigidity of the machine is raised and the kinetic performance of the machine is improved.

通过变加速方法降低惯性力，提高了机床的静刚度，改善了机床的动力学性能。

It also studied general variation regularities of wave force, added mass and added damping, TLP's kinetic respondence based on engineering examples and got some valuable conclusions (see text).

基于工程实例，分别研究了TLP波浪力、附加质量与附加阻尼、TLP的动力响应的一般规律，得到了一些富有工程意义的结论(详见正文)。

After 20 minutes, two men on dhol (a large handheld drum with the tubby resonance of the tabla and the kinetic force of a conga) who were not with the band joined the parade and started playing along to the music.

And I think in the past -- I have given you a blow by blow of the comparison in terms of sanctions taken in Bosnia, or the use of military kinetic force in Bosnia and how long it took for the world to act in those case.

WHITEHOUSE: Press Briefing

It will certainly condition how we view any use of force and kinetic action because I think we have a more precise understanding about the relationship - I won't claim we've fully cracked the code on this but we have a better understanding of the relationship between the use of force and the radicalization of those watching it.
