On the basis of dual feature identification method, combined with small wave analysis, it effectively extracts failure features, analyzes the stability power failure vibration signal feature on the general Fourier atlas, analyzes the shock power failure vibration signal feature on the resonance modulating Fourier atlas, using small wave to analyze the shock failure vibration signal feature.

是一种在"双特征判别法"的基础上，结合小波分析，有效提取故障特征，进行诊断的"三特征判别法"，所述的故障信号"三特征判别法"就是：在常规傅立叶谱图上分析平稳功率故障振动信号特征，在共振解调傅立叶谱图上分析冲击功率故障振动信号特征，利用小波分析冲击故障振动信号特征。

In this dissertation, the attention has been focused on the design and function predication of the modern Edger for the rolling line, which is significant theoretically and practically.

文章用系统的观点，从轧线大系统的角度阐述了立辊轧机子系统在轧线上的作用和功效，指出了原立辊轧机的多处先天不足，得到必须"推倒重来"的结论。

The article describes the characteristics in structure of edger stand at rougher area of 2150mm hot continuous mill supplied for Anshan Steel and the merits and shortcomings on the design in comparison with similar edger stands home and abroad.

介绍鞍钢2150mm热连轧机机组粗轧区立辊轧机结构上的特点，同国内外同规格的立辊轧机进行比较，说明该轧机设计上的优缺点。

These two things are what we will study in sectionⅢ. We call them GS and PS. In this section we will study the impact of the two and the relationship between them. Of course, there are some other ways to observe the problem. One of them is to consider the period and the distribution of eigenspace. These are what we will study in sectionⅡ.

这两方面也就是本文中第三章所讲的生成序列和扰动序列，这一章中我们主要研究了这两个因素对分数傅立叶变换算子的影响及它们之间的关系；当然还有另一种看问题的角度就是从算子的周期性和特征子空间的分布的角度，这就是第二章中所介绍的内容，在这里我们给出了两个三周期的分数傅立叶变换算子并比较了其特征性质。
