摘要
对“图解计算法”进行了新的研究,推导出具有普遍意义的正投影作图公式,据此可以确定任一已知形状相似形的单个正投影所示图形的实形,为一类射影问题提供了初等“图解计算”证明和解法.
A new study of “Graph-Computing Method”was conducted.A directprojection graph-drawing formula with universal significance was derived,according to which any of the real forms of the figures indicated by a singledirect projection of similar figures with given shape can be determined.Averification and solution of primary “Graph computation to a kind of projec-tion problem is provided.
