比方说，抛硬币的试验，我将正面向上的结果对应数字1，反面向上的结果对应数字0，这样我就定义了一个随机变量。

For example, the experiment could be tossing a coin, I will call the outcome heads the number one, and I'll call the outcome tails the number zero, so I've just defined a random variable.

并根据设计的硬币花纹工艺试验表明，选择较高的主脉冲频率，可获得较小的加工间隙，进而获得良好的表面质量。

It is indicated from the process experiment of coin figure that smaller gap and higher surface quality are obtained by choosing higher main pulse frequency.
