How does particle speed relate to figuring out what dark matter is?

微粒的速度和找出暗物质的性质之间有着怎样的联系呢？

The stronger the loaded shock, the stronger the porous effects. The pressure, density, temperature and particle speed do not approach their equilibriums at the same rate.

加载的冲击波越强， 材料的多孔特征越显著。 压强、密度、温度、粒子速度趋于或远离平衡的节奏并不同步。

By experiment, the curves and equations of relationship between the heat transfer coefficient and parameters of average diameter, particle size distribution and particle speed are obtained.

用试验方法研究了固体粒子绕流园管的换热系数，得出了换热系数与固体粒子的平均直径、粒度分布、颗粒运动速度等参数的关系曲线和关系式。

I have shown you yesterday that the speed of the particle as it goes around the circle is this .

我昨天讲过,质点做圆周运动的速率等于这个

A clock tells you what time it is, but you can also say what time it is by seeing how fast the particle is moving because you know it started with some speed.

时钟能告诉你现在的时间,但你也可以通过测量质点速度,来判断当前的时间,因为你知道它的初速度

Whenever you see a particle moving in a circle, even if it's at a constant speed, it has an acceleration, v square over r directed towards the center.

只要看到质点做圆周运动,即使是匀速圆周运动,也存在一个加速度,大小为 v^2 / r,方向指向圆心

Both use vast particle accelerators to speed up electrons, which spray out X-rays as they pass around the accelerators.

Because nobody knows what the mass of a Higgs boson might be, the particle must be hunted indirectly, typically in giant machines that propel particles to near-light speed, then smash them together and generate an array of other subatomic particles.
