轴测体视图的轴测轴和轴向变形系数的图解法

The Graphic Means to Determine the Oblique Axes and the Axial Coefficient of Foreshortening of an Oblique Stereograph

在绘制物体的轴测图时,轴测轴应根据物体的形状特征来确定,绘制其体视图也是一样。轴测体视图是由一对斜轴测图构成,而绘制轴测体视图的关键是体视配对图中轴测轴和轴向变形系数的确定。介绍了轴测体视图轴测轴和轴向变形系数的确定方法,给出了一个应用实例,并对不同观察方法下的体视配对图的位置作了说明。

When the object抯 axonometric drawing is drawn, the axonometric axes ought to be determined according to the characteristic of its shape. As its axonometric drawing is drawn, so its oblique stereograph is drawn. An oblique stereograph consists of tow oblique drawings. Determining the oblique axes and the axial coefficient of foreshortening of the oblique drawings in an oblique stereograph is the hinge, drawing an oblique stereograph. This paper introduces a method to determine the oblique axes and the axial coefficient of foreshortening of an oblique stereograph and gives a piece of stereograph. And it explains the position of the oblique drawings in an oblique stereograph that is viewed by different means.
