一、线共轭曲面的曲率关系空间两任意给定位置,按特定规律运动,并任意瞬时都保持线接触的曲面称为线共轭曲面。其特定规律运动称为共轭运动。众所周知,线共轭曲面及其共轭运动应用很广,根据给定条件及求解对象不同,在实际中经常遇到四类共轭曲面问题。 First, the curvature of the line conjugate surface The space two arbitrary given position, according to a specific law of movement, and any instantaneous line contact surface is called the line conjugate surface. Its particular law of motion is called conjugate motion. As we all know, the line conjugate surface and its conjugate motion is widely used, according to the given conditions and the object to be solved, in practice often encounter four types of conjugate surface problems.
