本文讨论了任意函数类的一条光滑平面参数曲线段，在适当的射影变换下，可以变为相应的有理形式的平面三阶参数曲线。

By using a certain projective transformation, a smooth planar parametric curve with any function may be changed into a new planar parametric curve of order 3 in a rational form.

该文利用自由幺半群上的有理形式幂级数理论，构造出该概率分布的约化线性表示，从而完全解决了噪声变量的概率分布计算问题。

In this paper, we propose a reduced linear representation of such distribution based on the formal power series on free monoid which can be easily used to calculate the probability distribution.
