从扫描雷达每次扫描中获得位置数据或者从轮流传输数据的通道获取信息，很自然地就得到可离散变量。
Discrete variables occur naturally, as from a scanning radar that obtains position data once per scan or a data channel that transmits many pieces of information in turn.
实验的自变量是图形的离散度参数，因变量是单位时间图形信号的视觉通道信息传递量。
The experimental variable was the dispersion of polygons, and the dependent variable was the rate of visual information transfer.
