摘　　要：本文提出在曲面体表面的展开图中确定截交线上各点位置的极坐标法,从而克服了直角坐标法中实际放线时由于画垂直线或平行线而产生人为的偏差,而且便于在现场实施.A polar coordinate method for determining all the points on the sectional line in the expansien figure of curved surface,is presented in the paper.This method is more convenient and accurate than that of traditional right-angled coordinate.It is easy to re- alize at the working site.
