So, just to get you used to this idea, I'm going to draw a level surface of a function of three variables OK, so it's a surface given by the equation w of x, y, z equals some constant c.

为了令你们习惯于这个想法，我画一个三变量函数的等值面,这是一个平面,由函数w=c给出的。

The vegetation cover and management factor ( C ) in the universal soil loss equation (USLE) is an index to evaluate this effect, which has been studied deeply and used widely.

通用土壤流失方程（USLE）中的植被覆盖与田间管理因子（C）是评价这种抑制作用的有效指标，并被广泛采用和深入研究。

c We know it's very specific for light because in this equation is c, the speed of light. So any time you go to use this equation, if you're trying to use it for an electron, just ask yourself first, does an electron travel at the speed of light?

我们知道它只对光适用是因为在这个方程里有,光速，所以下次你们用这个方程前，如果你们要把它用到一个电子上，先问问你自己，电子的运动速度是光速吗？
