《机械工程》杂志去年曾就机械工程学的历史形成与发展,以及所涉及的实际内容,探究过机械工程学的内涵与外延。为了在纵向予以深化和在横向予以扩展,本文再从科学基础来探究机械工程学的含义。 机械工程学包括涉及机械制造带普遍性,全局性、最一般性问题的学科。是机械制造业的理论基础。它研究与解决有关机械的计算、设计、制造与 Last year, Mechanical Engineering magazine explored the connotation and denotation of mechanical engineering on the history formation and development of mechanical engineering and the actual contents involved. In order to deepen vertically and expand horizontally, this article explores the meaning of mechanical engineering from the scientific basis. Mechanical engineering includes disciplines that deal with the universality, generality, and generality of mechanical manufacturing tapes. Is the theoretical basis of machinery manufacturing industry. It studies and solves the mechanical calculation, design, manufacture and
