In this paper the me sured results about the conductivity of the erth in the middle prt of China are given. The methods which are used to measure conductivity and the problem dividing erth's surfce into regions for equiv lent conductivity are discussed. And we suggest a method to make conductivity distribution map of China for time service and n vigtion at longwre.

Any areal symbol of a thematic map is made of aboundary line with certain sym- bols filled in it.The boundary line may be a polygon,a smooth curve of a combination of the two,and it can be drawn as those thiner elements,while the symbols to be filled are of different types,such as parallel lines,alphabets or other pictures,and the automatic drafting methods are quite different.The key point to draw parallel lines auto- matically within a boundary line is as follows:with the help of a computer,according to the digitized coordinates of the boundary points as well as the given parameters of parallel lines the position of their ends is to be found and then to connect them success- ively on the automatic drawing machine can be realized.In this paper,a mathematical method on the calculating of the coordinates of the ends of parallel lines within a poly- gon is introduced and the processes of lining,pairing and outputting are described.

专题地图上面状符号是由轮廓范围线加填充符号构成。轮廓线可以是多边形或光滑曲线,也可以是由折线和曲线组成,其自动绘制方法与一般线状要素同;填充符号可有多种形式,如晕线、字符、图案和其他符号,其自动绘制方法亦各不相同。在轮廓线内晕线的自动描绘,关键在于根据轮廓数字化的轮廓点坐标,按照给定的晕线参数用计算机辅助的方法确定晕线端点的位置以及用自动绘图机将晕线端点有序地联结起来。本文介绍在多边形轮廓范围内(规定数字化轮廓点时沿轮廓边按顺时针方向进行)计算晕线端点坐标的数学方法,以及晕线端点的排队、配对和输出的过程。
