机械类专业的内涵按传统说法,“机、电、土、化”是国民经济的四大基础工业。其中的“机”则是指机械工业,专司各种机械设备的制作和生产,它担负着为工农业、交通运输业等各部门(包括上述三大基础工业)提供机械设备和生产装备的重要任务,因而它的产品更加丰富多采,其服务面更为广阔。“机械”是一个大门类,按机械设备的功能可将机械分为工作机和工具机两大类。其学科体系也是比较繁杂的。根据学科性质及其内涵可分为“机械工程”、“仪器科学与技术”、“材料科学与工程”、“动力工程及工程热物理”等一级学科。每个一级学科下再细分为多个二级学科。如培养从事机械设计专业人才,培养机械 According to the traditional connotation of mechanical specialty, “machine, electricity, earth, and” is the four basic industries of the national economy. One of the “machine” refers to the machinery industry, specializing in all kinds of machinery and equipment production and production, it is responsible for the industrial, agricultural, transportation and other sectors (including the three basic industries) to provide mechanical equipment and production equipment Important task, so its products more abundant, its service is more extensive. “Machinery” is a major category, according to the function of machinery and equipment can be divided into two types of machine and machine tools. Its disciplinary system is also more complicated. According to the nature of the discipline and its connotation can be divided into “Mechanical Engineering”, “Instrument Science and Technology”, “Materials Science and Engineering”, “Power Engineering and Engineering Thermophysics” and other disciplines. Each level of discipline is subdivided into multiple secondary subjects. Such as training in mechanical design professionals, training machinery
