画法几何题解的定义域分析及表现形式研究

Analysis on the Domain of Solution of Descriptive Geometry Problem and Research on Its Expression Form

围绕画法几何习题解的定义域展开讨论,通过具体示例探讨画法几何题目有解的决定因素,设计题目应给定哪些不同条件,题解的各种表现形式,表明各种几何元素间的空间位置、几何元素的形状及其对投影面的位置均会影响画法几何题目的设计及定义域,不同题目解的定义域应分别进行讨论.

This paper discusses the domain of the solution of descriptive geometry exercises,probe into the decisive factors of solving descriptive geometry theme solutions through concrete examples,what different conditions should be given for a design problem,the various forms of problem solution,showing the spatial positions of various geometric elements,the shape of a geometric element and its position of the projection plane,which affect the design and domain of them,so the domain of solution for different problems should be discussed separately.
