Cubic Curves

The industrial waste water showed non-EKC characteristics while the industrial solid wastes and industrial emissions ( include SO2 ) clearly showed the characteristics of cubic curves .

其中，工业废水呈现非EKC特征，而工业废气与工业固废、二氧化硫则呈倒u型曲线的前半部分，而COD呈明显的三次曲线特征。

With the changes of actual demand and the emergence of a great deal of the ways of drawing curves , such as parametric cubic curves , B é zier curves , B-spline curves , NURBS curves .

随着实际需求的变化，曲线的绘制方式不断的涌现，如参数三次曲线、B（？）zier曲线、B样条曲线、NURBS曲线。
