Some parameters affecting the frequency and magnitude of power supply, such as supply voltage, duty of control sigal. the R and C of oscillation circuit are discussed.

对影响放电电压大小及频率的电源参数进行了讨论，如供电电压、控制信号占空比、振荡电路的R和C等。

The G-R relation between the earthquake magnitude and frequency has been an important premise in seismological study, but its actual distribution often deviates from its theoretic result.

地震震级频度的古登堡·里克特关系式(简称g - R关系式)一直是许多地震学问题研究的重要前提之一，然而实际分布常常与这一关系式有一定的偏离。

And then the predicted earthquake magnitude in seismic risk areas and the happened magnitude have also been taken into account, R-value of different magnitude levels have been calculated.

进一步考虑不同危险区预报震级与实际发生地震震级间的差异，文中还分震级档计算了相应的R值评分。

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
