This paper prorides a new approach to determine the interfingering lines of two tree - dimensional objects . this method can be used not only in solving the general interfingering lines , but also the complexed ones 本文介绍了一种用投影面的垂直面作为辅助平面来求解相贯线，它不但能解决一般相贯线的求解，而且能解决复杂相贯线的求解。
Abstract : by cooperating the two - model method with parallelogram frame in this paper , the curve of two crossed cylinders with their axises in a state of vertical can be easily and accurately realized , and the mechanism withdrawn from the method can be applied directly to the hole gas - cutting on high pressure capsules 文摘:采用双靠模法与平行四边形机构的组合，可简易、准确地实现轴线垂直的两圆柱体相贯线轨迹的复现，其原理可直接用于压力容器上圆孔的气割。
