摘要将一类非线性系统等价表示为时变线性系统，研究了非线性系统的广义预测控制。
In this paper , we use the main results of type 2 vdr to analyze the spherical symmetric distribution . we obtain the two equivalent representations of the spherical symmetric distribution . they are both a product of a positive random variable and a random vector with uniform distribution , and the domain of uniform distribution are both related with sphere
本文将第二类垂直密度表示的主要结论应用于球对称分布，得到了球对称分布的两种等价表示形式，它们都是一个正随机变量与一个均匀分布向量的乘积的形式，且均匀分布的区域都与球有关。
