《机械振动基础》是为航空宇航科学与技术、机械工程、力学、动力工程和交通运输工程等专业的本科生编写的基础课教材。《机械振动基础》共分6章，包括单自由度系统的振动、多自由度系统的振动、无限自由度系统的振动、振动分析的近似方法和数值方法、非线性振动以及振动实验。附录介绍了如何使用数值分析软件平台MATLAB计算振动问题。《机械振动基础》结构严谨，内容丰富，强调分析、计算与实验相结合，借鉴了国际著名大学的机械振动教学计划，融入了作者多年的教学和研究成果，反映了工程振动领域的新进展。("Base" mechanical vibration is written for Aerospace Science and technology, mechanical engineering, mechanical, power engineering and transportation engineering and other professional undergraduate course teaching. "Base" mechanical vibration is divided into 6 chapters, including single degree of freedom system, the vibration of multi degree of freedom system vibration, infinite degree of freedom vibration system, the vibration analysis of the approximation method and numerical method, the nonlinear vibration and vibration experiment. The appendix describes how to use the numerical calculation and analysis of vibration problem of software platform MATLAB. "Base" mechanical vibration strict structure, rich in content, stress analysis, calculation and experiment are combined, the mechanical vibration program of international famous university, the author has incorporated many years of teaching and research, reflecting the new progress of Engineering Vibration field.)

EMD 方法在理论上可以应用于任何类型的信号的分解， 因而在处理非平稳及非线性数据上，具有非常明显的优势,适合于分析非线性、非平稳信号序列，具有很高的信噪比。(EMD decomposition method in theory can be applied to any type of signal, which in the non-stationary and nonlinear data, with a very distinct advantage, suitable for analyzing nonlinear and non-stationary signal sequence, with a high signal to noise ratio .)
