This book gives a detailed introduction to the technical background, feature extraction methods, PHM models and big data embedding methods of the big data theory in PHM for intelligent electromechanical systems. Combination with deep learning and big data, this book explains the hybrid algorithm framework of PHM such as ensemble intelligence and optimized intelligence and introduces PHM models for bearing, IGBT, MOSFET and other components and their big data embedding platform. This book improves the PHM method and theory of electromechanical system under industrial big data and provides reference for the development of intelligent electromechanical equipment and intelligent industrial production in the future.

《前尘不扫》是一部自传体长篇小说。作者曾做过"知青"、矿工、公务员和留学生。退休后，他以自己的传奇人生为题材，耗时六年，完成了这部作品。此书以主人公坎坷的人生经历为主线，通过对人物心路历程的剖析和对那个特殊年代的客观描写，反映出当年那场声势浩大的"上山下乡"运动，对国家和那一代人所产生的深远影响。此书情节跌宕起伏，人物塑造形象逼真，景物描绘新颖别致，凸显作者文字功底之深厚、感情世界之丰富和阅历之广博，更显示出作者"嬉笑怒骂皆成文章"的写作风格。
