摘　　要：用形式逻辑关于下定义、划分等理论,结合工程制图教学实践,分析了GB/T17452—1998《技术制图图样画法剖视图和断面图》中的概念、画法、标注中存在的逻辑问题,提出了相应的修改建议。意在探讨技术制图标准中概念、画法的科学性、严密性,使之不断完善;同时,也使工程图学学科的概念更趋于清楚,以利于发挥标准在工程实践中的指导作用。In the light of the theories about Definition and Dividing in the Profoma Logic, combined with the teaching experiences in the engineering drawing, the logic problems were studied systematically, which existed in the concept, the method of drawings and the noting of the GB/T174521998《Technical Drawings Representation of Drawings Section and Cut》. The correlative suggestions of mend were put forward to discuss the validity and strictness of the concept and the drawing method in the Technical drawing criteria, and to improve them continually; At the same time, the concept of engineering drawing science was made clearer, which will benefit to exert the instructive action of the standard in the engineering practice.
