Experiment results showed that the relation between exciting voltage and induced velocity magnitude was linear, but the influence of supply frequency was not evident.

实验结果表明，等离子体激励作用主要集中在近壁面附近；激励电压与诱导速度近似为线性关系，激励频率对诱导速度的影响不大。

The fact that when you go in a circle, you accelerate is what we're learning here, coming from the fact that velocity is a vector and its change can be due to change in the magnitude or change in direction.

而当你做圆周运动时你也在加速,这是我们在这里所学到的,原因就在于,速度是一个矢量,其变化可以通过改变模长,或者方向来实现

take the derivative of this, get the velocity vector and you notice his magnitude is a constant Whichever way you do it, you can then rewrite this as v square over r.

对这个式子求一次导,就能得到速度矢量,你会发现其模长是常数,不管用什么方法,加速度也可以写成 v^2 / r
