机械图样是工程界的技术语言,图样的通用性必须靠国家标准的权威性来做保证。因此,必须充分认识国家标准在制图教学中的必要性、重要性、紧迫性、时效性和适用性的特点,努力培养学生的标准化意识,运用标准绘图、读图的能力以及严谨的作风,为今后的学习和工作实践奠定良好基础。 Mechanical drawing is the technical language of the engineering community. The commonality of drawings must be guaranteed by the authority of national standards. Therefore, we must fully recognize the necessity, importance, urgency, timeliness and applicability of national standards in cartographic teaching, strive to cultivate students’ awareness of standardization, the ability to use standard drawing, reading pictures and rigorous style as The future study and work practice laid a good foundation.
