机械工业是我国的传统工业，机械装备技术直接影响和制约国民经济诸多领域的发展。信息科学是一门迅速发展的前沿学科，已经渗透到国民经济的各个领域。文章从机械产品的角度出发，讨论了如何用信息技术来提升和发展传统的机械产品，提出了机械产品信息化的内涵、特点与实现的步骤；结合作者过去的一些科研实践，重点分析了机械产品信息化过程的信息融合和特征提取两个技术关键；文章最后强调了理论开拓是产品拥有自主知识产权和核心技术的前提。

Mechanical engineering is the basic content in traditional industry in China. Especially, the development of mechanical equipment will confine the development of many fields in national economy. The information technology is a frontier subject with rapid progress, and has been penetrated into many domains. This paper discusses how to use information technology to motivate and develop the traditional mechanical engineering from the viewpoint of mechanical product, i. e. mechanical product informatization. The paper introduces in detail the connotation, characteristics and realization steps of informatization. Combining with some achievements in authors' research practice, the paper mainly analyzes information fusion and feature extraction during the process of mechanical product informatization. In the end, the paper proposes that the theoretical breakthrough is essential for assuring autonomous intellectual property and kernel techniques.
